Gents,
This weekend I fitted up and chambered a 4 groove Krieger in 6.5 Creedmoor. Prior to doing this, I took the advice (I don't know why...I know it all already) of Butch and a few others and bought some Vipers Venom cutting fluid from Grizzly and a Warner threading tool with HSS inserts. A threading and a chambering I went...
...Holy Cow!
I don't know if it was the Vipers Venom, the Warner tool, or a combination of both, but I've never made prettier threads! I spun the barrel at 60 rpm's and the threads came out as smooth as an infant's arse. I hate to cover them up with the action...
I also chambered (pre-bored) with the Vipers Venom, and with my Kiff built reamer, I've never cut an easier or better chamber. I chamber at 80 rpm's (because I don't have the plumbs to chamber at Kiff's recommended speeds of 180-200) and felt no undue pressure on my Bald Eagle floating reamer holder (My big fear with spinning the higher rpm's is having the reamer holder tear my fingers off, pull me into the lathe, etc.). What has been you guys experience with the higher rpm's?
The Viper's Venom/Warner Tool/Kiff combo cut that barrel like butter. I'm very pleased.
Something else I did that is a bit out of the norm was to push my reamer holder using the carriage, as opposed to the tailstock. I have dowel pin that I ground to a smooth, round profile on one end a la the pusher on the Bald Eagle set-up. That side will push the floating holder. The other end I grab in a 5C holder for my KDK tool holder. I spin the dowel pin in with and indicator to nuts, and away I go. I do all this because I can use my DRO to keep track of my cutting depths and starting points. I find it easier than using the dial on my tailstock, or messing with indicators. I also find it easier to maintain a consistent rate of feed on the reamer this way. If I chambered like Jackie recommends (and it makes total sense), and I have, running the reamer in a bit deep and building the tenon around it, this would be unnecessary. But for some reason, I am more comfortable doing the turning and threading operations first, then chambering. To each his own...
Anyway, I'm very pleased with the Viper's Venom and Warner Tools maiden voyage. If you're thinking about pulling the trigger on one, the other, or both, I recommend them. And thank you to Butch and the others here on the forum for sharing their advice and experiences.
