Title: Sine bar calibration
Post by: Conman on 09-22-2016 -- 08:23:02
I have a Fowler 10 x 1 sine bar. I haven't had much experience with sine bars and I'm needing calibration information. What is the calibration requirement for sine bars?

Machinist handbook.

Well, that response was full of helpful information...

I found at least two places you can look, one explains a lot about Sine Bars and the other is a discussion group with a couple pointers on where to get some more information. Oddly enough, neither pointed to the Machinist manual for calibration techniques.
Have fun!
