[QUOTE="J E Custom, post: 437545, member: 2736"] I like to hold the reamer with a live center and a tap handel so that I can feel the reamer cutting, and 30 to 40 thousandths is normally max depending on the reamer. Some reamers load up with .030 feed so I back of and feed .020 to .025. Most reamer makers say that you can run faster than I do but I dont have a lube system "YET" and I run 40 to 70 spindle RPM to keep from heating the reamer any. also at these speeds I can feel the instant it loads up and needs to be cleaned. I know this slows down the chambering job but not by much and my reamers are extremely sharp after a dozen uses. Everyone has there way of doing chambers and this is mine. PS: The smaller the reamer the quicker it will load up because of the depth of the flutes. On the 17 HMRs I can only feed .010 to .015 without cleaning. J E CUSTOM [/QUOTE]
