I am looking to make a inspection table that will go onto my optical comparator. What I need to be able to do is hold onto a cat50 tool holder and be able to spin it freely 360 Degrees. So pretty much what I need is a spindle shaft with a cat50 on the end and hold onto that with some angular contact bearings and a good base.

Anyone know where I can go about getting a Shaft that will hold onto a Cat50 tool holder?
