Engine decking issue(help)

My brother-in-law Greg has worked for Landis Machine for a whole career from apprenticeship to near retirement now. They are one of the lead suppliers worldwide of cam and crank grinding machines, and I get to talk with him about their advancements. They have implemented a lot of new electronics to measure things like minute bed deflections and make corrections while running, and the accuracy improvements have been beyond 10-fold. But that is all going to new machines that can do new technology work like grinding 20' long gas generator crankshafts.

Things like milling decks are old hat and the tolerances simply don't require the new whiz-bang technology accuracy. The place in the next county up from me with the high $$ fantastic CNC machine will do all the local shop can do, but will charge $400-500 instead of $200.
