Barrel Chambering
I use a floating reamer guide to chamber the barrel I have made a special round handle that I attach to the reamer and
hold while reaming so I can tell if its dragging I never back out a reamer with the lathe running I simply let go of
the handle when I reach my depth which rotates the reamer I thenstop the lathe, back off the tailstock, and remove the reamer
After each cut (0.100 at first and then later 0.050 until nearingheadspace dimension) I remove the reamer, blow it off, blow out thechamber, dip the reamer in mineral spirits to clean it thoroughly andthen dip it in cutting oil
I place the reamer into the chamber, carefully run the tailstock up toit and crank it in until the tailstock moves backward and is at a zeroindicated on the dial where I tighten it down
I then back the tailstock cut setting off slightly and pull the reamerback to the reamer guide mounted into the tailstock, turn on thelathe while holding the round reamer handle and run it in to theproper depth using the tailstock.
