Hello Practical Machinist,
I have been a lurker here for a while and have finally run into a problem that I would like your advice on.
I have acquired an older Mitutoyo 12 inch Height Gage at a local auction in unknown condition. I repaired the battery cover and put a new battery in and the display came to life. However when I was checking using some gage/joe blocks I discovered that the height gage was off linearly by roughly .0005 in/in so at the bottom it would have an error of zero and at the top(12 inches) it was off .006 inches and in the middle it was off .003 inches.
The thing I don't know is what direction the top is leaning. The base feels solid and doesn't rock and I can't get a feeler gage in anywhere to find a high spot.
My next idea is to blue the bottom of the gage and run it over the surface plate a bit and see if I can get the high spot to show up. Let me know if this a a wise idea.
Basically what do you think would be the best way to bring this height gage back into spec (+- .001)?
Thank you for your time.
