Best practices for threading and chambering.

That was fast. Thank you,

I thought that was what it must look like.

Your idea is sure a lot safer than a tapping handle.

I don't know that it ever happened to me. But I got worried about the soft copper wire. Probably me over tightening the jaws. I made a split ring from a piece of aluminum. It has a heavy chamfer on each side about .375 wide taper on both sides to give .250 contact surface on the barrel so it can pivot. Just another way to skin it

You certainly can over tighten the jaws, been there, done that. One of life's valuable lessons. Now all is good, and still use the wire.

I think we should all be able to talk about pro and cons, issues we have found with certain methods without directly putting down some one else or their ways. These kind of threads could be valuable if they dont end in shit slinging.

Amen to that

Bamban,

I use the same type of setup and in my opinion its the only way to hold a barrel with out bending it. When you loosen this style of "chuck" the barrel will move in any direction and when you tighten it, it will stay there with out any influence to push the barrel back. Also, once its tight and bind free the barrel is held rigid with steel so it doesnt shift while chambering. I get the barrl exactly where I want it before using the outboard spider. This chuck will hold the barrel right where I want it. Then I tighten the spider just to support the muzzle, not force it into possition. This is not the case with copper wire... Also my reamer holder/pusher. Round so you cant influence the reamer, ball bearing in the back of the pusher, pushed by a ground carbide pusher. Chambers measure the same size as the reamer...View attachment 991998 View attachment 991999 View attachment 992000 View attachment 992001

How do you dial that in? Thanks

First 3" of bore running true to the spindle of the lathe. as close to .0000 as I can get.

You can do that just by adjusting that chuck? Do you use an indicator in the bore or indicate off a rod, pin ect? Thanks

Thank You Alex for the detailed explanation. I've learned from it and I appreciate it. Hoz

I do not chamber in my 10EE, I use my 6913 Clausing. It would be a piss poor lathe that couldn't cut a tenon without taper even though it is hanging out more than I do. He doesn't cut his tenon in one pass.

Don't know if it helps, but i always run the final pass three or four times without moving any thing. The shavings look like the oil pan sludge in a small block Chevy. Liquid steel ?
