I recently picked up a 30" x 60" x 10", 4 ledge Rahn granite plate on a stand for $500 off of a local-ish craigslist. After another $140 in trailer rental (drop deck from Sunbelt) and gas for the truck, I'm not all that much into a decent surface plate. According to the one legible certification sticker, it was a grade A plate in the 90's. Now, since I want to use it for scraping in my mill and straight edges, I need to get it properly certified. Does anyone on this forum know of a surface plate certification and lapping outfit that will travel to a shop in central Michigan? Does anyone know what a sane or good price for that size plate would be?
Thanks!
