This instructable will show you how to make a very cool looking ball bearing out of wood. I have always been interested in ball bearings, so I decided to make one my self, and I decided that making one out of metal would be too much like bearings that you can buy, so I chose to make one out of wood.
This bearing consists of 3 parts, the inner race, the outer race, and the balls. Most ball bearings have what is called a cage that is pressed in to hold the balls in, but I could not make that so I made this with the outer race as 2 parts glued together.
Step 1: Tools and Materials Required.
The tools that are needed to make this are:
Wood lathe with a faceplate (A metal lathe would work very well, but be careful turning wood on a metal lathe, because if you leave saw dust on the lathe it could rust)
Drill bit assortment
Wood Chisel (Or utility knife)
2 5.5 inch squares of 3/4" thick wood (I used pine because that is what I had, but hardwood would be better, but anything you can turn on your lathe is fine) this is going to be the outer race
1 3" square of 1.5" thick wood (I cut this out of a 2x4) this will be the inner race
Material for 9 wooden spheres (see next step)
Super glue/ Wood glue
