I recall that machine being able to flatten a piece to something like .010". I think that's higher precision than most wide belt sanders, but otherwise it's just like you can buy from any major machine supplier. I think it was made in Italy. They also have an incredible, huge orbital buffing machine, with three big buffs on a carriage which revolves, while the whole thing moves linearly over the length of the piece, such as a lid. The size was eye-opening. -Mark Albert Thomas wrote: > Thanks Mark Schecter for the links: in part three of "Touring the > factory" they are running lids through an electronic sander.
