A little how-to:

  1. Cut stencils from 110-lb paper

  2. mark stencil mirrored on back of record

  3. (i use a) Dremel Tool with these bits

  4. The trick is to learn how the "burn" comes off of the record while you cut in order to get clean edges

  5. Trim frayed label and rough edges with small Xacto blade.

  6. Wipe with vinyl cleaner.

General advice, some obvious, some not, in no particular order -

Get a step bit. I can recommend this set of 3, which is $9 shipped -
They are great for aluminum. If you want to drill through something harder than aluminum, they will do the trick but use a drop of WD40 or oil where you drill.

Drill BEFORE you paint and sand as it's easy to hose your paint job if you drill after painting. If you must drill a painted enclosure, drill through blue masking tape so the little curls of aluminum don't cut spirals through the finish.

Measure a lot and make sure your stuff is going to fit and be centered. Pencil and a ruler and blue tape are helpful. If you are doing it a lot you can make a wooden drill template.

Make a starter dent with a punch as mentioned below.

Clamp your enclosure in place before drilling. If you're using a drill press and value your fingers you really gotta do this.

That's all I got. Good luck!

u/thegoddamntrain · 10 pointsr/Wet_Shavers

You're going to have a hell of a time keeping the hole round with a dremel. If you don't have a drill press available, hand sand it with some coarse (80 grit or coarser) sandpaper, it'll take a while, but it's much easier to control. Another option is to drill it out with a drill press, clamps and a forstner bit; just have to be sure it's clamped down well and you have it perfectly centered before you start drilling. Easy way to do it is to start with a step drill bit, knock down the top lip to the size you want and drop the forstner bit into the recess at the top before you hog the rest out with the forstner.

Giant mousepad protip:

You can use MTG playmats as mousepads. They're larger, the same material, machine washable and cheaper than an equivalent steel series. I can fit my 10keyless keyboard and mouse on this while browsing and move my keyboard off while CS:GOing.

I start my hole with a Dremel and the round (ball) bit of a diamond Burr set found here:

Once that's through I finish up with a cone shaped 1/2" Diamond Burr set made for a real drill:

I haven't used the second ones, cause I bought mine off ebay but I used the exact dremel bits on the first link

u/TheMetalDetectorist · 7 pointsr/smoking

River Country!!! To install in the WSM, I had to purchase a unibit and drill out the hole to 13/16" to fit it in, but this thing is affordable and bang-on accurate!!!! Stole the idea from T-Roy Cooks on youtube. Additionally, there's a set-screw type deal in the back where you can calibrate it - so if you wanted it to sit in the hood like I have but actually read what the temp is at the grate level, you can stick a probe in at grate level and calibrate the River Country to read what that reads- so even though it's placed in the top of the smoker, it will read the correct transcribed temp from the grate level. Couldn't recommend this therm enough.

Oh man, I wish I were crafty and skilled enough to machine metal...

My Fiancee got this for me as a gift and I love it, here's the link: Jewelers Universal Holder

I was looking at mini holders and couldn't find anything I liked. The top is a hex grid with circular holes for pegs and you can adjust it for all kinds of base sizes under 50mm

There's even a Desktop Version of the Jewelers Holder (though its a little more expensive)

u/khanable_ · 6 pointsr/ender3

Outside of the things others have mentioned (springs, tubing, couplers, SKR, BMG, etc.) - if you don't already have some good tools/spare parts you can use this time to invest in some.

u/reverendwrong · 6 pointsr/StonerEngineering

Absolutely! Just make sure you have either ceramic, diamond, or carbide bits otherwise you're gonna destroy all the bit heads. If you don't have them I may suggest either of these...

...they ain't the worlds best bits but the price is just right and they've lasted me at least 3 projects, and will probably make it another 3 for sure. And they're cheap to replace!

u/FuzzyRocket · 5 pointsr/cosplay

Dremel is a name brand for hand held rotary tools. I have and have had several so I will give you my .02

Vacuum powered - You connect it to a shop vac or other vacuum and the suction powers it, while this may sound good on the surface I can't see this having anykind of power from this I suggest avoiding it.

Cordless - Battery powered, I have had several. You get less torque than with a corded version, and they run down. I do have their new micro version and I like it so far, but cordless will always be a balance between power and battery life.

Corded - Best bet IMHO, get more features for less money than with the cordless and do not have to worry about waiting for one to charge.

Suggested Features -

  • Do not stick with a single speed version, go with variable speed. In fact the more speed options the better IMHO. Different bits require different speeds, for example a cutting bit needs to run quicker than a wire brush.

  • Multi Tool chuck - Some bits come in different diamters, this one will take them all. I love this and have replaced the old style chuck on all of my units.

    Bits - This will depend on what you want to use it for. I use my Dremels for everything from mixing epoxy to cutting and sanding everything (metal, wood, foam, fiberglass, etc). You can get more for your money if you buy a family of bits in a kit (example) but a few bits I have found most useful are:

  • Sanding drum - then you buy the different sleves that slide over the tip and come in different grits. Again look for kits.

  • Cut off disk - Go for the re-enforced ones like this

  • carbide disk - Love this thing it cuts wood and softer material very well.

  • carbide bits Come in many shapes and sizes, I find that they work well for shaping wood and softer materials.

    NOTE Like most power tools, a rotary tool takes a bit of practice, they can get away from you and eat up material (including your jeans and leg) if you are not careful. I have found that 90 percent of the time a light touch.. pull back.. and light touch.. pull back is the best method.

    edit: spelling and format
u/desrtfx · 4 pointsr/3Dprinting

A fairly simple method:

  • bend the brim first against the model and then backwards - repeat a couple times and the brim will fall off
  • use a deburring tool (sample only - first link I found) to remove the remaining brim.
u/shadyguyinthecorner · 4 pointsr/Homebrewing

Just drilled holes in the same kettle.

I used this step bit along with some 3 in 1 oil. It was a breeze! Nowhere near as hard as I had anticipated.

Start out drilling a small pilot hole. For the pilot hole I used a faster drill speed and a small amount of pressure. After that the step bit will easily get through the stainless steel. For the step bit, drill slowly, take breaks to add oil, and use a decent amount of pressure. Each rotation should be making progress, otherwise you are just heating and hardening the steel. Finish stepping up the correct size drilling from the inside of the kettle, this will deburr and flatten the hole.

Good luck!

u/ArmstrongTREX · 4 pointsr/prusa3d

I am mostly recommending tools rather than consumables (like a truck load of filaments :P)

A digital caliper, use it every single day, must have. A $20 Chinese made should be more than sufficient for the tolerance we are printing at.

A pair of good quality side cutter. Prusa printers don’t come with them.
Hakko Micro Cutter

A Noga deburring tool. Very useful for finishing a print and trim sharp edges (brims for example). Cuts plastic like butter.

A set of taps. Can’t get very strong thread in plastic, but often good enough. I would prefer a metric set.

A vise. Depends on how much space you have. I use a drill press vise and I find it ok so far.

u/fmephit · 3 pointsr/amateurradio

I used a stepped drill bit designed for cutting through sheet metal to cut my NMO mount in the roof of my pickup. Like, one of these:

Way easier than trying to align a punch, and no bending of the edges, etc. Took about 10 seconds to line it up and step it out to the right size.

u/pedgaro · 3 pointsr/Wet_Shavers

Cut the crack down with a round file, sandpaper on a 1/4" dowel, dremel..burr might work best or a bench grinder. If it's the alum block and not the stick, just use the other side.

Standard Ultrapro playmat tends to run around $20. You can get cheaper ones that are plain if you want. creates custom playmats for $25. I personally recommend them, as I've enjoyed every mat I've gotten from them.

u/xakh · 3 pointsr/3Dprinting

Ooznest is great, they actually used to sell an i3 kit that was quite good, and my goto for Great Britain recommendations insofar as cheap-ish kits were concerned. Last I checked they're a genuine reseller, so what you got should be the correct component. Anyway, if you want to upload a picture, the easiest way is to upload it to an external image host, like imgur, for instance, then link it in your comment.

So, by broken in half, do you mean it looks like this? If so, it is possible to overtorque the two halves against each other inside an M6 nut. It'll be pretty wobbly, and it definitely won't last for more than a couple of prints, but it should work enough to get it through a single print. Actually, since you ordered from Ooznest, you're probably in the UK, or nearby in Europe, right? That means hardware stores should just carry most kinds of metric fasteners, and you can get ahold of an M6 coupler nut, which would definitely join the two halves together long enough for you to get a print off of it. In addition, you could get an M7 tap of some sort, and drill out the Anet's original heatsink. The E3Dv6's heatbreak is an M7 on the top, M6 on the bottom, so that could work. You'd have issues with heat creep long-term, since the E3D uses a metal interior instead of PTFE like the Anet does, but you'd probably be able to get the mounting adapter for an E3D off of it before it gunked up too much.

u/antaymonkey · 3 pointsr/Homebrewing

Only thing of concern to me is that it says max temp is 170° F. Strike and sparge temperatures are very borderline there.

u/cleansoap · 3 pointsr/bicycling

Should be using a stepper bit anyhoo.

Or a reamer.

Or even a file.

Auger bits are for drilling holes, not enlarging holes. Especially in sheet metal / tubing.

I applaud the ingenuity and OP should be happy they got the job done, but others should consider best practices.

u/caddis789 · 3 pointsr/woodworking

Dremel has some attachments that would work (like these). If you don't have a dremel, you can run them in you drill.

u/ExHempKnight · 3 pointsr/AskReddit

You'll need a pencil grinder (or a Dremel, if you don't have an air compressor), and a small teardrop 1/8"-shank carbide burr (something like THIS... 5th or 6th from the left). You'll also need a steady hand, because you'll be grinding that bit out. If you're careful enough in removing the broken bit, you should be able to drill the hole a little larger, and use the next-size-up extractor. I don't know if you used an form of Loc-tite on the bolts, but you may have to use a bit of heat as well.

Source: Aircraft mechanic for 10 years, and have removed many bolts/screws in this fashion.

u/The_Mushroominator · 3 pointsr/shroomers

Warm the surface up. I use a heat gun for a few seconds, but a hair dryer will work as well. It cracks because the plastic is brittle. Give it a little heat and it gets a little more pliable. Not too far or you create a whole different problem. There are also different drill bits you can use. I've had great luck with Forstner Bits
and an almost perfect record with Step Bits

As u/FungalScripture (great name BTW) says, go slow. Keep pressure on the tool very light, and some support on the back side of the plastic you're drilling through can help too. Best of luck.

u/shanniganz · 3 pointsr/Nerf

I would also recommend picking up a set of these:

They are invaluable for shell work.

u/dorpal_the_great · 3 pointsr/minipainting

Thank you, I'm glad you liked it. They're not my highest quality work but I'd call them good enough for tabletop. Especially if I was doing an army of these. This is the vice I use. It's pretty handy, especially for filming.

u/Metalsand · 2 pointsr/engraving

There's a decent one for like $25 that you can buy.

It's not quite as fancy and smooth to use, but it's highly functional for irregularly shaped objects such as rings that can be difficult to hold in place.

u/illuxion · 2 pointsr/electronic_cigarette

friction fit tips are something like a cherry vapes cloud chaser or the ones I got on ebay. It just depends if you like it really airy or not, some don't. Here's the underside of 3 of my tips, the ones with the smaller holes are standard and the same size as the hole in the Stillare. The big hole is a Cherry Vape tip, the hole happens to be around 5/16, so I opened up the stillare to match. Just make sure the hole in the stillare is the same size as your tip, or the top cap will be the limiting hole. To do the actuall drilling I used the long skinny bit from these bits

u/baileyp03 · 2 pointsr/minipainting

I'm not sure about foods, though imagine some exercises could be beneficial. Years back I injured my hand, nothing serious but a bit of scar tissue limited how much I could bend my finger. I ended up seeing a physical therapist that specialized in hands. Perhaps you can talk to one or just find out information through online searches for exercises to help steady your hands. I know, not a ton of help, but maybe it's a start.

In terms of things specific to mini painting, a good holder can help. I use something like this. You can also get a table mounted version which sometimes I'll use for very fine detail freehand work. That allows me to also use my other hand to help steady the brush if needed. Place the index finger of your other hand against the brush just below the bristles and apply a light amount of pressure. I think you'll find this gives you an increased amount of control.

When I paint, I find I often extend my pinky (on the hand holding the brush) and will rest it on either the figure or the figure's holder while I paint. It's something I do without thinking most of the time. It helps my hands (the one holding the figure and the one holding the brush) move together and gives me a sense of greater control.

u/Smooz · 2 pointsr/whatisthisthing

The shape is similar but I think those bits might be a lot smaller. These have a 1/8" shaft

Small to none. You would have better luck at a local machine gun. Harbor Freight might have one, since they import everything from China, but a for warning they suck. They are cheap on Amazon and Ebay.

u/coherent-rambling · 2 pointsr/woodworking

If you're working with soft materials, you want something called a 0-flute countersink. They're designed for merely deburring metals, but in wood and plastic they make beautifully clean countersinks. There are several brands, but Keo is the one I'm most familiar with and can endorse.

Check out the sight glasses at Brew Hardware. I've purchased many items from Bobby, and have had good experiences.

Assuming a weldless application, you'll need a step bit for your drill. The one linked worked great for me. When drilling, use oil to cool the bit and go SLOW or you'll harden the steel.

Bobby's install/calibration videos can be found here and here.

Good luck!

u/jared213 · 2 pointsr/Vaping

For my longer jobs like drilling and grinding the air holes on kayfun lite clones I actually hold it under dripping water in the sink. For smaller quick jobs I've used old e liquid, since it can be a pain in ass to wash out machine oil and I have a bad full of e liquid that I don't use. If you use the automotive sand paper you can just wet it with water, the paper I got is made for wet sanding. I think I got it from Walmart it was years ago when I was panting truck parts so it may have come from an auto parts store.

This is the last diamond bits I bought

Just take it slow on the glass and smooth the sharp and I think you'll be happy with the difference it makes. Oh and if you try to mod any metal parts don't force the bits down into tight holes like small air holes because they can overheat and break of in the hole and it sucks trying to get them back out. I learned how important patience is real quick doing that, and keeping your work cool and lubed.

u/Bacun · 2 pointsr/OklahomaJoe

For those interested, here's a pic of the inside.

Here's a list of my mods.

  • Grommet on the side for probe access: So handy! The most useful mod. I used this titanium drill bit to create a hole large enough. It took me about an hour of sweating my butt off with the drill to make the hole. I feel like this mod is a must because if you use any kind of probe this will be a lifesaver. Constantly closing and opening the lid of the smoker with the wire in the way will eventually damage the wire. With this grommet bypassing the door entirely, you don't risk damaging the wire anytime you open or close the lid. If your hand slips when opening the lid and the lid slams down, it can CUT the probe wire! Lifesaver indeed.
  • Lavalock Thermometers x2: I bought two of these for both sides. Tested them for accuracy with boiling water and they work pretty great.
  • Lavalock Gaskets: I used these to seal the lid of the main chamber. It helps create a seal for lower smoke leakage.
  • Clamps: These make 100% sure you are airtight when smoking. When used together with the gaskets, I get virtually no leakage from the main chamber. One annoying thing though is that the clamp installed on the side of the fire chamber can get in the way of you opening and closing the fire chamber lid. But, overall I'm happy with them, especially for longer cooks.
  • High Temp Silicone Caulk: This is a MUST. The areas around the smoke chamber leak smoke SO MUCH. I've used it to seal around every nook and cranny of the fire chamber and it's done wonders.
  • Water pan: Not sure if this counts as a mod, but it's just a simple steel water pan.
  • Oklahoma Joe Firebox Basket: The reverse flow smoker came included with this. I think the regular Highland Smoker does not have it. In my opinion, it is extremely helpful in maintaining heat throughout your cook and makes the temperature fluctuate less.

SE DT220R 180 Grit Diamond Burr Set, 20-Piece

Use the egg-shaped bit. Hold the bottle under a small stream of cold water in your sink so that it is rolling over the spot your going to drill. Use a dremel on highest speed. Go slow and occasionally lift the bit off the glass while you're drilling. Once the bit is through the glass, use the sides of the spinning bit to sand away the glass and open the hole to to desired size. Bob's your uncle and you got a pipe. I'm currently in a pipe/bong making phase and this is my method.

I'm particularly proud of this one... Recycled Coca-Cola bottle 2-chamber glass bong

u/BrewerMan · 2 pointsr/Homebrewing

It's working great! Electronics wise the only thing I would change is going with all Auber PID's, but I have the Mypin ones tuned pretty well now.

On the mechanical and equipment side I have added a hop spider, and I am considering adding some sort of automated stir thing to constantly stir the mash and increase efficiency. But thats about a year down the line to be honest.

I also added one of these to help prevent tunneling in the grain bed, it works great after enlarging all the holes in it. I have also been playing around with a plate chiller, but it is proving to be more trouble than it's worth. I bought a new chiller a while ago but haven't gotten around to playing with it yet.

u/ImmortalCorruptor · 1 pointr/magicTCG
  • Take your time learning. Magic is kind of like Chess in the way that it's simple to pick up and play but takes a lot of time and effort to master and no one becomes a guru overnight.

  • If there are any specific cards you're looking for it's usually cheaper to buy them individually instead of gambling with booster packs. There's a chance to pull some $20+ cards from boosters but the odds are heavily stacked against you.

  • Know what your cards are worth and don't be afraid to turn down a trade if you aren't 100% certain of the value of everything involved.

  • Always keep your expensive cards protected and keep your decks stored inside of deck boxes so they don't get crushed or bent. Using rubber bands to keep cards/decks together can seem like an acceptable budget solution until they start to bend or wear the edges of the cards, which turns a $50 card into a $0 drink coaster.

  • It's definitely worth investing into some card sleeves for your decks. They make decks easier to shuffle and prevent your cards from getting dirty. I can't tell you how many times I've seen people open a valuable foil rare from a booster draft, play it unsleeved for the tournament and then find out that no one wants to trade for it afterwards because it's completely scratched to hell.

  • You also might want to look into getting a playmat. It's not nearly as mandatory to have as sleeves but it helps extend the life of your cards even further, it guarantees that you'll be playing on a clean surface and it helps mark your space at a table.

I did something similar a few months ago, but I used a drill press. They're kind of expensive so I'd ask around for one you can use. You need a step drill bit. Just mark out where you want your holes to be and make sure the cymbal is clamped down nice and tight, then drill away.

I bought a cheap chinese set of carbide burrs from Amazon. $11

I used the cylindrical one with the round head to grind out two bolts that held the sway bar clamps on one of my W163 MLs. The bolt goes through the control arm and the two clamp halves and is a colossal pain. The head breaks off of the bolt almost every time.

Very time consuming and it takes a lot of pressure on the drill to make it cut but it worked great. I used a 2x4 as a level and was probably putting close to 100lb of pressure on the drill. Took forever but it worked.

u/tsaico · 1 pointr/DIY

I like these types of drill bits, step drills for small metal projects.

They are great for thin metals, especially since I don't do lots of drilling into metals, I can have many different sizes on a few bits.

u/cannababushka · 1 pointr/StonerEngineering

Now that I’m home and have a minute to type, here’s how I made it:

-I used a step drill bit to cut two 3/4” holes in the mason jar lid. I kept the lid on the jar while drilling, held the jar with one hand and the drill with the other and it worked just fine (I marked the holes with a sharpie before drilling)

-I put in one hookah hose grommet and one “downstem grommet” (I get these from my local ace hardware. You just ask for a rubber grommet with an inner diameter of 1/2”, an outer diameter of 31/32”, and a 3/4” groove, I think the stock number is 55059) in the holes I drilled

-downstem time. I get them from a local smokeshop and I use just regular ol’ glass on glass downstems that work with a 14mm bowl. Before you fit it into the grommet, lube them both up with whatever cooking oil you have on hand (I use coconut oil). Getting the downstem in is the trickiest and scariest part to me but it goes relatively easy if you coat it in oil first

-all set, just put in a 14mm bowl in the downstem and a regular hookah hose in the hookah grommet and you’re good to go

I have 2 and I prefer my Dremel brand one because it has 5 speed settings whereas my B&D only has 3.

My Dremel is a 3000 but there are lots of options in the Dremel world. I would say to avoid wireless/battery operated ones if you plan to ever use it for metal cutting because battery operated ones tend to lack the speed and power of a corded model.

Also consider investing in a rotary file bit or 3 ( - the circular cutting bits are a pain to angle sometimes and are useless for rounding corners, etc. A rotary file bit is great for when you want to shave away a surface instead of cut INTO a surface. Kinda hard to explain in text. You'll see what I mean if you ever try them in person.

And here you go:

SE 82331TF 30-Piece Set of Titanium-Coated Diamond Burrs, Grits 120-150

I've been pretty happy with those so far. I think I might try my hand at engraving sometime soon.

Sorry, went to bed. As long as you are slow and deliberate, I wouldn't think you would have a problem with cracking. There are some issues with the glass flaking off where you cut it, but that can be fixed with sanding.

I used these bits to finish the edges after cutting. The "globe" bit, 7th from the right, is what I used to drill a drainage hole in the glass.

edit: also, for sanding the edges, get Emery Cloth, it's in the sandpaper isle at home depot. It's sandpaper that is bound with cloth, so you aren't going to cut through on a sharp edge when you are sanding it down.

u/abronia · 1 pointr/guitarpedals

Not OP, but you just need a set of set drill bits and a cordless drill to drill through enclosures. Takes a few seconds to drill through to your desired size!

u/TheDarkHorse83 · 1 pointr/Homebrewing

I picked up a WinWare aluminum boiling pot for $40 last year, drilled a hole in it (I think that the bit was $20) and installed a $20 valve. Since purchasing it, I've used the bit for two valves, a thermometer, and two sightglass installs.

Edit: The pot

The Bit

The valve

Holiday Deal Valve Alternative

You might be able to find better deals on Cyber Monday, though.

All you need is a drill gun and dish soap (the soap is a nice lubricant so you don't wear the bit down quickly)

u/BrewCrewKevin · 1 pointr/Homebrewing
  • I recommend 8 to 10 gallons. You will need plenty of space to prevent boilovers.
  • Like skunk says, maybe get one with no fittings and start with BIAB? I know you don't have the tools now, but you really only need a step bit for your drill. It's super easy if you get weldless fittings from
  • I would def recommend a dip tube. They aren't expensive if you already have a ball valve, too.

    I'll agree with skunk in that I think the sanitary fittings was a bit overblown. I use threaded fittings on everything and have never had a problem. I take them apart about every 5 batches or so to clean them more thoroughly, but they stay pretty clean.
u/puffers · 1 pointr/crafts

You are absolutely going to need diamond tipped bits. This is not at all easy to do. This IS going to result in a ton of broken attempts. Please make sure you wear really good eye protection AND a respirator. I have not made any designs on/in glass with a dremel but I have had to drill several half inch holes in the side of bottles before. If you go to fast it will break. If you let the dremel bounce or get out of control it will probably break the glass. If you look at it wrong it will break the glass...seriously though, it is something that is going to take some practice and a steady patient hand. I wish you the best of luck!

u/alf3311 · 1 pointr/Homebrewing

Depending on how big a hole you are making, it might be easier to do it yourself. If you have a decent drill (preferably corded by a nice cordless one will also work), you can get a step drill bit and some cutting oil. You do not need a punch unless you are doing a ton of holes or are doing something very large.

u/theruthlessnb · 1 pointr/knives

I bought these:

CO-Z 5pcs Hss Cobalt Multiple Hole 50 Sizes Step Drill Bit Set with Aluminum Case

And turned them by hand or very slowly in a drill.

u/BL24L · 1 pointr/BudgetAudiophile

I highly suggest picking up a step drill bit for making holes in cabinets. Makes a cleaner hole then a hole saw and easier too,

*A hole that would take me 10 min of frustration with a hole saw is basically as easy as drilling a normal hole with a step drill bit.

Here's a picture of a hole I drilled with that same bit at work. The top "hole" was done by whoever did the installs here. The bottom hole was with that drill bit I linked.

u/saucedog · 1 pointr/Woodcarving

Thank you so much for this info, c0nduit. I really appreciate it. I aim to do carving in the round. I'll see if I can get away with a generic big hook instead of the stand. Would a hook > spring > motor help keep the motor's sound down / keep it from rattling or vibrating the wall/cabinet the hook is connected to? Or is that a non-issue? My bench doesn't support any of the elevated stands they sell.

Thanks for letting me know the big burrs that come with the kit are functional and I had no idea fire is the best medicine for a clogged burr. Thank you also for a look into your workflow. I will pick up the detail diamond files. I anticipate them being very helpful. I'll also get the diamond "detail" burrs cause they're also cheap and it sounds like small diamond burrs will work well enough in moderation. Hopefully those and a basic detail knife set for edges will get me through the first few projects and aim me towards a stronger detail game-- hopefully without acquiring another power tool :]

Am I right to think the small diamond, almost engraving burrs might be OK for very limited detail work? Or would they get clogged immediately and be a huge pain to repeatedly clear out?

Thanks again for 1 -validating my research and 2 - your thorough answers. This is a really big help.

u/ItzDaWorm · 1 pointr/trees

Well this + this(1.75L) should work ok. At least its what i plan on using shortly.

u/thepirho · 1 pointr/trees

that one seems a bit big, possibly smaller ones are cheaper?

hole saw set - says diamond tipped

hole saw - 1 bit 3/4 inch

dremel kit - must have a dremel for sufficiENT speeds

I used a half inch spade bit and it kinda cracked my first one

Has slide to bottom and then removable bowl
stuff at neck is hot glue for a air tight seal, glass was to thick for gromit that came with the slide

bottle cutter - for other fun things

u/themellowmedia · 1 pointr/watercooling

Haha sure thing, its a rather simple mod. All you need is a through hole fitting.

Basically, it allows you to create a pass through on the case where you can screw any type of G1/4 threaded fitting into it. For the plug, you can use any type of G1/4 stop fitting.

The best way to drill the hole is to use what is called a step bit. So you drill a pilot hole with a standard 1/4" bit, and then you use this step bit to step up the size of the hole. If you are only going to be doing it for this build, I would recommend getting the link I provided as most of these bits go for $55 at your local hardware store.

All in all it's easy-peasy. Just be sure you know for sure where you want the port to be before you drill ;).

u/studiouspanda · 1 pointr/lockpicking

Thanks everyone for the advice everyone, I probably would have bought them had I found them yesterday, but I decided to go the DIY route. Since picking must be a very budget conscious hobby for me, I went ahead and took the plunge and bought the important tools. I figured making my own pins would be difficult and require a lot of crazy equipment, but I looked into it and realized it was a lot easier than expected. So just for anyone who's curious, here's what I got:

  • $50 Kwikset rekey/pin set from eBay. 200 of each type of pins, 8 types of pins. Clips, followers, springs, and anything else needed to reassemble locks. That leaves enough pins to make absolutely every security pin that I know of, as well as any others that I find from watching people pick challenge locks. There are a good variety of these sets, so you can save some money here by getting only 50 or 100 of each pin type if you prefer. I just decided to start off big so I hopefully never have to buy another.
  • $35 Rotary Tool. Used for a huge variety of DIY projects, including and excluding lockpicking. There are some cheaper options, but in my opinion you're better off buying at least a decent one to start so you don't have to upgrade later.
  • $7 Needle File Set. Used in conjunction with your rotary tool as cutting/smoothing tools
  • $25 Base Vice. Also is very useful for holding locks while picking.


    So in total $112 for all the components needed to make as many locks as I can imagine, many of which can be used for other projects.


    To add supplies for a few other DIY projects I also added:

  • $6 Rotary Tool Bit Set. Used for various DIY projects.
  • $9 Cutting Wheels for your Rotary tool.
  • $6 Wood Plank. I'll use this along with the dremel bit set above to make a nice pinning tray.
  • $2 12" x 0.5" x 0.023" Stainless Steel Feeler Gauge. Used to make picks, tension rods, etc. making it $2 per 2-3 tools. If the thickness you want is expensive/in short supply on amazon you can buy directly from the manufacturer here but in my experience the shipping is slower and the price is usually a ~$0.10 higher per 12" rod. If you really get into making DIY tools you can buy stainless steel feeler coils from easterngage which are 25' x 0.5" x 0.15"/0.18"/0.23"/0.25"/0.26" or any thickness you want really. For 25', depending on the thickness it'll cost you anywhere from $50.64 to $64.95. You might need the 1" wide coils for making double sided tension tools.


    So another $21 brings it to $133 plus $2 per 2-3 tools that you need. Add in this $6 case and a few $4-$6 practice locks around aliexpress (1st, 2nd, 3rd, 4th 5th, 6th, 7th), and you've got a great starter kit that sets you up to DIY anything you might need in the future. I also took advantage of Peterson's mega christmas sale (plus the 10% discount code they gave us) and got a ~$25 order of $1-$3 picks to start me off
u/Electric_fuzz · 1 pointr/StonerEngineering

Rookie mistake to buy a $20 drill bit, when you can get 20 for $4

u/underachievingazn · 1 pointr/Yugioh101

Amazon is a good choice. Inked Gaming has ones with custom art if you're into that.

u/dudebroski · 1 pointr/airsoft

Here it is on Amazon. Try searching "thread die" for other shops. CCW are also referred to as "left hand" threads

u/SanityIsOptional · 1 pointr/CAguns

Try using a deburring tool to chamfer the edges of the cut.

u/Funbunion · 1 pointr/trees

I think it's definitely worthwhile to drop a few bucks on glass drill bits. There about $15 in a hardware store or you can look online. I got this set and immediately made a nice steamroller. Be aware that they're too small for most downstems.

He gives an instruction sheet with it. Let me snap a picture.

Sorry about the cell phone pictures. I don't have a scanner anymore since I went to a cheap color laser printer.

edited to say: I need to break down my MK3s and put in those tubes but haven't done it yet as I'm waiting to finish doing upgrades to my ender3 and setup my anycubic photon, basically I can't be without a 3d printer and have been limping by with my MK3s with the jamming issue. I currently follow this guide:

The Chassis: Most of the handle is MHS v2 (where the leather wrap is), and then both ends adapt up to MHS v1. Because of this I ended up going with Goth 3D chassis parts that are 0.99 OD. But they are modular pieces, so you pick and choose which ones you want. I needed to use spacers between some of the parts so that I could route the cables through, so I put spacers between all of them to look cohesive. Other than the Goth 3D parts, there are a few Skywampa, TCSS, and other various hardware bits. Everything is linked below.

Goth 3D

  • Crystal Chamber part 1 in polished nickel steel
  • Crystal Chamber part 2 in polished gold steel There is 1 LED in the bottom of this piece
  • Chassis part 1 in plastic white - Soundboard Was perfectly sized for the Warsabers board
  • Chassis part 2 in plastic white - Battery
  • Chassis part 3 in plastic white - Speaker Had to mod the speaker so this would fit inside the handle
  • Chassis part 4 in plastic white - Recharge port
  • Chassis part 5 in plastic white - Spacer disc

    Excluding the crystal chamber parts, the Goth 3D chassis parts were all white, which was a mistake. Should've done black. So I painted all of them in a few steps. 1st was paint them flat black. 2nd was paint them graphite. 3rd was a layer of silver leaf Rub'n Buff thinned with enamel thinner and applied to just the outside to help it look more like metal.

    Here are the other pieces of the chassis with explanations:

  • Skywampa 1" chamber part These are used as spacers between the crystal chamber and the chassis. Also helped with providing a channel for the wires.
  • Skywampa 35mm Graflex to MHS connector disc. This is the disc between the blade holder and the MHS Chassis disc below. You need it to connect the two pieces together. It's not on their Etsy page right now so I can't link to it.
  • TCSS Chassis Disc Style 4 This is the part that threads into the handle and holds a 2nd LED for the crystal chamber.

    The Skywampa and TCSS discs are treated with a combination of Aluminum Black and Ebony Rub'n Buff to give them that "weathered" look.

    Here are the various hardware bits to connect all of it:

  • Crystal for the crystal chamber Picked one that looked right but was a little big, then reshaped it some to fit properly
  • Brass rods that run the length of the chassis These were treated with Aluminum Black to look old. I also tried carbon fiber and steel rids but like the brass ones the best
  • Steel spacers These are between the the fins, crystal chamber, TCSS disc, Skywampa disc, & blade holder
  • Screws to connect the TCSS disc, Skywampa disc, & blade holder
  • Crimp Beads These are the spacers between the battery, soundboard, recharge port, & speaker chassis components.
  • Brass tubes between the crystal chamber and the TCSS disc. Don't remember the size though. These provide a little extra stability for the brass rods because they flexed a little too much for my liking.
  • 5mm LED bezel Two of these, one on each side of the crystal chamber.
