That was a cutting oil problem 'Looky and we have that all under control now, have several gallons of different oils, 1 heavy duty cutting for high friction, 1 heavy duty stainless steel specific and 1 Sulflow, high sulpher cutting oil, which I just found again, and have cut 100 chambers with without grief. So I should be good now............need to bounce up to my friend/mentors place, for a few days, after Xmas and make another 1/2 doz barrels............ I am also going to work on making an oil delivery system for pumping oil through the barrel from the muzzle when chambering. This will ensure enough oil to the reamer when cutting, reduce heat build up and help to clear chips. I have it all figured out on how to do it, just have to build the different components and get a low pressure oil pump and sump.
I will only need 10-20 lbs pressure so it won't be too difficult to attach it and o-ring it to the muzzle, anyway like I said I have it all envisioned in my head, all I have to do now is get off my a$$ and build it.
