Ed,
I initially set up the X,Y,Z axis with the original iGaging aluminum scales which are easily cut with a common hacksaw. When I decided to make a collar for the quill and mount a scale there I ordered one of their short ( I think) 12" alloy (stainless) scale. Turns out it was too long and I didn't know if I could cut it with a abrasive wheel in a die grinder. If I ruined the scale I would have to buy another so I just ordered one of the original type aluminum scales for the quill. I'm using the 12" alloy scale on a old Monarch lathe I have.
So the short answer is I don't know for sure as I have not attempted it. Sorry I can't be more help.
