action shoulders.They look real goodafter lapping. Thenew headspace is0.950. I am now onto turning the shank,

threading, insetting,and chambering thebarrel.

Barrel Setup for Bench-rest Quality ChamberingI try to get the bore run-outwithin .0001 at both ends of

the barrel and check to makesure Im not stressing orbending the barrel in any wayby using an o-ring on thespider the electrical tapeholds it in place so spider will

flex if barrel is stressed.

Test to Make Sure Bolt Drops Freely(Barrel is now ready for Chambering)

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.
