Modifying my Granite Surface Plate Stand for 3 Point Contact
The granite plate and stand I own I purchased used at an auction. Lance is going to help me measure and lap it to AA standards but first I need to modify the stand so that it is setting on 3 points. The location of these points are also important and are based on the size of the granite plate. This information was taking directly from The American Society of Mechanical Engineers.
There's any number of ways one can do this, including making the contact points adjustable. I kept it simple with a couple of tubes welded to the frame, drilled, and installed some plastic contact points to rest against the bottom of the plate.
I will later replace those old casters with some newer ones, I just didn't have any nor the time to do that while I was at Lance's. It'll also get a rattle bomb paint job.
I'll also be publishing a video of the lapping we did on this granite plate.
