u/Nemo_Griff · 4 pointsr/lockpicking

Gut the lock entirely then put the lock into a vise and drill the caps all the way through with a drill bit that is smaller than the caps.

After that you can use a punch with a hammer and knock the caps out. The hole allows some relief for the cap to slide down the chamber without doing a lot of damage on the way down. I would suggest that you drill and punch every other one to start.

Start off with a M3.5 tap and run it all the way through to make it a serrated chamber. To replace the caps, use a M4 tap to widen the diameter a bit and replace the caps with M4x4mm grub screws.

This was how I did it.

The screw is an m3 grub screw, 6mm or 8mm long. Not sure. I would recommend you measure your existing one.

u/chaosissteve · 2 pointsr/electronic_cigarette
  1. Lightning vapes has 316l clapton spools, all I've been using lately. It's really good. Had the same one in my serpent for 2 weeks. 25 feet for 11 bucks and fast shipping.

  2. If they are the same as the serpent mini grub screws, which I would imagine to be true, these will work.

This should be what you're looking for. As far as I know, all saber manufacturers use 8-32 screws.

u/Tourtoise · 2 pointsr/FidgetSpinners

Ahh yeah sometimes you just have to swap the screws on some buttons to make them more compatible. It’s a pain for others but I personally like having the flexibility to adjust. Here’s the assorted set screes I have

u/glennac63 · 2 pointsr/FidgetSpinners

I recently got this set. I’m finding most makers use the largest size (M3), but don’t use the longest length (6mm). I often find that after adding desired spacers the installed grub screws are not long enough to reach. Switching the 4 or 5 mm originals for 6 mm work great.

I checked my box too. I got spare philips instead of hex. But I found a link on Amazon that were the same specs and preferred by a lot of vapers.

u/regallegion · 2 pointsr/MechanicalKeyboards

While I'm not sure which height you would want, something like these brass standoffs are what you want. That being said, you would likely have to get some sort of headless screw (these are just an example, not sure which kind would be best or fit) to screw into the case and then use tiny m2 screws to hold the plate on.

u/the_duck17 · 2 pointsr/ak47

If you use an inconel screw for the gas restriction, then a set screw and that would be using the same high end parts on ar-15 adjustable gas blocks on the market right now.

If you can use a spare gas block to know where to drill into your current gas block, I don't see why you can't get this to work on the cheap.

As far as I know, Tyler uses standard M4 threads on his pedals, which seem to be the most used in the industry.

Perhaps set screws and and some threadlock will do?

I much prefer metric set/grub screws...the trick is don’t crank’em down...IMHO. you don’t get any better connection by over-torquing.
