make a lathe test bar
I'm needing a one inch lathe test bar. Finding ground and polished one inch
material is a piece of cake. The bar needs centers on each end. If I just
chuck the bar in a one inch collet and bore, I'll pass on the 0.0005 inch
runnout of my collet to the test bar.
How would you do this? Or do I just buy the test bar?
