DSC_0013 (640x426).jpg Hi, I had a 1/2 inch KMG small wheel self destruct months ago and I kept the damaged piece on my workbench and just looked at it from time to time. I needed a small wheel for a blade and so I punched the axle out of the bearings on my vise and chucked the axle in my drill press and sanded the remaining rubber off of it. I pressed the bearings back on with the vise and tried the wheel which is now about 3/8 + a little in diameter. It worked great. I had the idea to make a 1/4 inch small wheel so I searched for the sealed bearings on line and found part number 1ZGD4 on the Grainger website. It is a Dayton sealed bearing measuring 7/8 diameter with a 3/8 bore and a width of .2812. They are $8.10 each. I asked a machinist friend of mine if he could make an axle to fit the bearings and he said no problem. He called me less than half an hour later to announce the wheel was done. I do not know if he used his lathe or his mill to make a brass bushing to fit both the 1/4 inch stock and the inside of the bearings but he said it was easy. I know that many of the knife makers on this forum have the tools to do this. I used the 1/4 inch wheel today on a little round next to the blade and close to the scales on a finished knife and it worked well making a nice finish on the blade. I though some of you would could use these if you haven't already made something like this. I have 3 Dremel tools on my bench plugged in but these tiny wheels are easier to use than Dremel attachments IMHO. Larry

Those bearings can be gotten in packs of ten on then bay also for less than $20 delivered.

Someone else posted their version of small wheels that use various diameter tubing over the appropriate sized shaft.

Your came out super nice. With a lathe, the options really open up with a project like this.
 
PT Doc, Your shopping is sure better than mine so thank you for sharing that info with the forum guys. I don't feel bad because the other small wheels I bought cost $60 each plus shipping but I had to have them. Hey, by the way did you find any bearings with an inside diameter of 1/4? That would be super easy. LL

Can't say that I looked for the id. A lathe would solve all problems. A cnc lathe setup would make quick work of these.
