Recently a friend who is a retired railroad machinist for the C&0 gave me a electric motor driven reciprocating hack he built 30 some years ago. I replaced the wiring to include a new cut off limit switch. The old G.E.. motor tests out good. Cuts good and is a really nice addition to my small shop. Do any of you folks have plans for this sort on machine? I believe he said it was in Popular Machanics magazine. It would be handy to have the original plans, just for history sake.
