When I owned 10% of one particular company my forte was in figuring out how to simplify a fabrication operation by making a few simple fixtures many critical assemblies could be tacked and welded up up with great precision and have nice smooth welds even the ape handed monkeys they had working for them were hard pressed to screw things up When it cam to drill jigs which do you think is more productive? A fixture that will hold up to 10 parts that may have as many as 20 hardened guide bushings locating every hole in the exact spot or tacking a stack together and having to lay out each and every hole in the top piece of each stack? When the company sold instead of getting money I got the 20 or 30 tons of fixtures and jigs mostly made by yours truly and all of the machines plus most of the inventory because the brand was being moved to South Africa Later I converted many of the fixtures and jigs to metric plus made new ones which could not easily be converted and sold them to the new company
