always, if you deal with any machine shop, assume your dealing with a guy who really doesn,t give a crap,
and print out in fine detail , what you want done ,,EXACTLY....with specific dimensions and a diagram,
with ALL those dimensions printed boldly , try hard to get both a firm delivery date and a agreed upon total price
IN WRITING WITH HIS SIGNATURE, and several pictures of the parts and him holding the parts and a receipt
that the parts listed individually, to be worked on are in what ever condition they were in, TAKE LOTS OF PICTURES
this will be a minor P.I.T.A. but it will save you a whole lot of misunderstandings and arguments
never deal with any shop that says things like,
"come back next week I should get too it by then"
or "stuff like that generally costs about$300-$400, but I won,t know until I get into the project"
or won,t give a firm delivery date, price or sign a
receipt, or agree to a firm price... youll see why if you ignore this advice in spades
