(Part 2) Best precision balls according to redditors

For anyone interested I used-

• 1/2"1/4" Chrome Steel Ball Bearings
  
• All-Purpose Epoxy
  
• 4mm1/8" x 1/16" Rare Earth Magnets
  
• Dremel 7200 Cordless
  
• A thumb tack
  
  I used two magnets for the B-Wings instead of a magnet/ball bearing because the weight of the B-Wing on the side was too much to hold it the way a B-Wing should look.
  
  The Dremel obviously made the job easier than using wire-cutters to snip the pegs down which is what I saw most people use. It also was used to sand down and make a nice flat surface for ball bearing and magnet mounting.
  
  I dremeled off the peg stands as close to the ships as possible, to maintain as close a center of weight as possible.
  
  The one problem I did not anticipate was the 'spinning' effect most ships had when placed on the ball bearing. To solve this, I used the thumb tack to draw a very small, thin line of epoxy down the center of the magnet to create a friction line that kept the ship in place no matter how I placed it, i.e. 'barrel rolling'
  
  It was a fun challenge and the bearings and magnets were about $10 (100 pieces) each and the dremel I just happened to have anyway, but it goes for around $30 at home depot.

Looks like polished steel rather than stainless, a clue is that you can pick them up with a magnet. Many types of stainless are nonmagnetic. color is also a bit off, but that may just be the white balance of the picture.

Amazon will sell you 100 BB sized 420 stainless ball bearings for about $8. That should be plenty to last for a good long while.

I also have a suggestion on agitating the paint - use a reciprocating saw. File the points off an old blade and rubberband the paint pot to it. 20 seconds of that should be plenty to agitate any paint pot you own that isn't totally dry.

- squibs

- french bangers/petards

- firecrackers (maybe)

other methods. slingshot/hunting slingshot - nice and cheap. I think you get ones for fishing. Buy one of them, the ball bearings, then shoot at a vase from a safe angle (including the camera) and it'll shatter. will be hard to spot the ball bearing in the picture too. may want to put a board up nearby so the ball bearings aren't flying off rogue like and shattering something unintended after it's hit the vase.

rifle. even those ones you get at the fair that you put the little metal pellets in. again, these will shatter a vase - you won't see the pellet on screen - just be sure you're not aiming at the lens, or a crew member ;)

best of course if the projectile is hitting from behind, so the stuff flies forwards. from the sides and it'll look pretty silly, just like a bullet not like an exploding vase.

safety glasses recommended at all times. it's not worth you or your crew losing an eye just for a shattering vase. be safe, but good luck!

Do they need to be perfectly spherical?

Here’s a 3” ball bearing but it weighs 4 pounds.

One 3" Inch Chrome Steel Bearing Ball G100 https://www.amazon.com/dp/B0074VCMFE/ref=cm_sw_r_cp_api_i_t2wMDb7RV17MG

To get it closer to 1.5 pounds you’ll probably need cast aluminum.

Here’s a 3” steel ball but it weighs 13 ounces. It’s hollow though, so maybe you could drill a hole, fill it full of a material to get it closer to your goal weight, and then refill the hole?

What do you need this for and maybe that will make suggestions easier?

I did, and you can also do it yourself. It's not like I used some rare materials you don't have access to.

You don't even need to buy a balance, you can make it yourself very easily, and you could use a rock instead of a ball bearing.

Hello Guys, I wanted to share a technique I use to retain. Mostly I do this on days when the skin needs rest. The weight of the ball provided a littel pull. And dam it feels good.

here's the link to where i bough them https://www.amazon.com/dp/B007B2A64U/ref=cm_sw_em_r_mt_dp_U__DO26BbHVP6PKS

I wouldn't order those 3/16" bearings. They are stainless steel and stainless is many times non-magnetic. Here are the bearings I ordered:


3/16": https://www.amazon.com/gp/product/B002BBD4P4

1/4": https://www.amazon.com/gp/product/B0012LHL9O

I didn't order 3/8" but that link you provided is probably fine for those.


I ordered 1/4" because according to the chart in the KJ blog post, it looked like the 1/4" bearing fit the 3/8" magnet better to me. I haven't installed a large ship yet though so I don't know if 1/4" is a better option (and I expect that it isn't since everyone seems to use the 3/8")

These work fine:

Also available in 1" and up sizes for a little more.

They are cheaper ($8 for 10) if you don't go with stainless, but I would go with stainless.

I would have to look and see if shipping was worth it, but I have a few 1" chrome steel left if you want to try one out.

At nearly 26 year old bike. At the very least the grease is going to be full of grit and should be repacked. Yes bearing will fall out and you could loose them, but bearing balls are cheap. Pack of 100 3/16' is $5.53 on amazon. The biggest issue is reassembling the axles. It took me a bit and alot of frustration to get the front wheel to spin smoothly. The headset is much easier than hubs. Watch youtube videos, and make sure you have the right tools before you start. There is a thing about to much grease, so dont go overboard. At the worst, you would need to take it to the bike shop and get a hand reassembling. Best case, you learn how to take care of the bike and more about its function.

Convincing your Dad you should do it, I cannot give you a sure fire way. Maybe compare it to a car, you change the oil every 3000-10000(new cars) miles, Tires get changes, air filters. Regular maintenance. Bikes need it too. Lubing the chain, checking the air pressure, replacing worn out wheels. Replacing stretched chains.

At the very least, I would get a chain checker and see if the chain is stretched. If it is, it will wear out the chain rings and cassette which if those are original might be worn out too. The jocky wheels on the rear derialer might need to be serviced. Those have small bearings and if they are play in them, should be replaced.

My Dad was the same way, in 50 years I have never done that to my bikes and they just worked. Yes they do work but not smoothly or efficiently. I just do stuff without talking to him (at first), now I take care of his bike and he does admit it is nicer to ride.

I'm assuming these are the equivalent of the NSB3 and NSB6 ball bearings? Amazon prime link

NSB6: 3/8 inch ball bearings

NSB3: 3/16 inch ball bearings

I have a ton of big ball bearings laying around for some reason so I just use those and they work great, Theyre a bit expensive if you don't buy them in bulk though, but here's 1000 of them for 2 cents a ball on amazon

I just made my first last week with this 3/4 inch steel bearing.

I didn't need a jig whatsoever. Found a tutorial on youtube and it was easy as pie. I wish I got a pack of larger bearings though. Next time I'll order a pack of 1 inchers.

How about a RUNNY NOSE SHOWER DISPENSER

I didn't see that you're looking for something for him to take to work. How about a SARCASTIC BALL

After you graduate from the golf ball...

I then used these agitators, but I would use glass beads if I was doing it again 100 x 6MM CARBON STEEL BALL BEARINGS https://www.amazon.co.uk/dp/B00HDL3L50/ref=cm_sw_r_cp_apa_p2W6BbW5YH8G5
