Refurbishing Skate Wheels

To turn a new surface on a set of used (or new) skate wheels, you will need access to a lathe and a special mandrel to hold each wheel.

This mandrel was made using some 22mm shaft (same size as 608 bearing OD) that I had laying around. I also ordered a 22mm collet to hold the mandrel for maximum precision.

A specially shaped bit must be used to cut urathane properly. It will have a very positive rake and deep chip breaker on the top, almost a knife edge.A turning surface speed of around 375 Ft./Min has been suggested.

Freezing the wheels may make it easier to produce a nice finish in some cases.

DO NOT inhale the smoke or grinding dust from urethane or any elastomer or plastic. It is toxic.
