Re: Reamer Speed
your stated speed of 45 rpm will cut chrome moly great but the s.s. barrels usually cut better faster like the other guys stated. I can "feel" the flutes filling up your experience may differ but others have agreed with this. Also I've spoken with other smiths that have stated they cut Stainless at 150 r.p.m. and up. Probably depends on lubrication. Here's some comedy for you, I volunteeered at a pancake breakfast and they were pouring grease off of a cookie sheet where they were cooking sausage patties, I asked if I could have that job and they looked at me like I was crazy. I saved a gallon of the nice clear stuff off the top when we were done and used it recently to chamber a 8-.280 Ackley in Chrome Moly barrel at @30rpm, This sounds crude no pun intended but I swear that was the slickest chamber I ever did. Don't laugh till you try it, it smelled better too.
