If I want to move forward with the carnival ride restoration, I need to machine the shaft. Technically, it is far too large for my lathe. However, after some careful measuring, I realized I just might be able to machine it, if I had a steady rest.
Although a steady rest has been on the wish list for a long time, I never came across one for a price I was willing to spend.
I came across an ad for OSHcut laser cutting and started to think about building something from a sandwich of steel plates.
