Hey guys. For my Heavy 10 I had secured it to the concrete floor using fine threaded rod epoxied into the concrete, which also allowed leveling. Well, for my 12x36 the floor is pretty even where it's going. The bases are only off front to back about 0.005", per my machinist level, and they are heavy cast iron. I'm thinking of anchoring the bases to the floor so the lathe doesn't move but instead of using threaded rod to level the bases I would use shim material. What type of shimming...
