6" .30 Luger barrel, 1900 style

[ithacaartist]

When I talk to the guy about clocking, indexing, and proper barrel vise and system to hold the extension without damaging it, and finally headspacing check/adjustment, I should be able to gauge his abilities. I'm hoping, as is very possible, that the replacement will crank right on just fine, however, I'm also aware that clocking and headspacing have their own needs and remedies. If he says he has a .30 luger chamber reamer already, I'll begin to think we can do it here. He's also a machinist, and even though he might not have specific Luger experience, I think we'll be fine.

One more question: I've seen the dimensional range for proper headspacing discussed before, not too long ago. Could someone with the figures please post them? My search didn't turn up the post I wanted...

I don't recall seeing that thread. It seems everyone who does re-barreling/re-chambering has a different idea of what the 'proper' headspace should be.

Military headspace and commercial headspace are different. Military is much more lenient. Commercial is much tighter, and IMO more accurate.

I had an old six inch barrel blank that was left over from my initial attempts some 30 years ago. I have pretty much viewed it as a mistake, kept to remind me how not to do something. But seeing your six inch 30 cal 'pencil' barrel and looking at my 'mistake', I decided to see if I could salvage it.

It didn't come out as well as yours (I suck at finishes), and it wasn't until I read the two pages here that I realized yours is in 30 cal...Mine is 9mm...

Oh, well...It looks better now than it did 30 years ago...
