I would have used EDM but we aint invented it here yet...LOL
Now I may have to start over!
No CISI but there is CISC - deals with Construction steel.
Oh, it aint "EY", ya know, like, it's "Eh"!
Ja, reel gut dere- guess I've been watching my two "Cabin Feverwinterbound older movies too often" -- The Shinning and FARGO--Construction and metal fab steels are a tad different than 4140--but ferrous metals and codes and std. machining practices are pretty straight-forward-- No EDM machines in the great lands of: Walleye, Hockey and great beers?? Shame, that. One of my shooting pals has a fairly complete machine shop-- and he has a EDM--just don't ask him to "punch out" relief ports with it in the muzzle area of the barrel of your Weatherby shoulder-breaker--
