This keeps getting and better better
You realize SS will be an absolute bear especially if it’s 3xx series. The whole thing about milling down .024 to .004 is whacked.
You are in for bad times. Buy a roll of .004 SS shim stock as suggested, pay someone to laser cut to shape and pass the cost on. Your customer is an idiot or a 20 something newb engineer (cartoonist) don’t follow them down a rat hole.
