Barrel spinner/ polishing aid

spinner dimensions

I've been meaning to ask for specific dimensions as well. I have some 3/4" 12L14 that would probably work fine for the centers.

Here is an AutoCAD drawing of mine that I made, complete with dimensions. The bearing I used is just a standard R8 bearing. I think I got them off eBay for like $5 or so.

Thanks DSM!

I thought you did it in cad and started to ask for the drawings but didn't want to ask you directly.

I thank you sincerely and now everyone can use them!

Take care, BP

No problems...if you have any questions, feel free to ask.

Hope they work out for you.

I worked up my own drawing just today - but I need a bearing in my hand to measure so I can calculate clearance - but nearly identical!

The bearings in my spinner are 7/8" O.D. and 3/8" I.D. by 11/32 thick. The local "Bearing Distributors" in my town sold them to me. I think they are Japanese. You need to have high speed bearings, obviously.

Someone else mentioned using 12L14 for centers. I would advise against steel centers. Wood, plastic, or brass would be much easier on the barrel.

Thanks Bill.

I ordered (2) 1/2" i.d. x 1-1/8" o.d. x 3/8" thick bearings from http://bearingsdirect.com/1616-ZZ-Ball-Bearing-1/2x1-1/8x3/8-Shielded.html - probably a lil over kill but they'll work.

Say hello to Mike Wiskey for me ;-)

Learn as you go!

It works perfect - I revised the drawing so the bearings press in a little easier, and opened up the through hole so the bearings can be pressed out if ever needed! I put it together today and tried it out and it works fantastic! Definitely cheaper than buying one...
