Outer Barrel Sleeve possible?

I'm contemplating building an MP38 with as much accurate detail as is possible given my ability and resources. The barrel blank I have to work with is slightly too small in diameter (it's 0.8 inches) as compared to the MP38/40 barrel at its widest. To add to that, my lathe can only handle 0.688 inches max through he spindle shaft.

I think I can rough the diameter down enough with crude means to get it in the lathe, so I thought about making a sleeve that would slip over the breech end of the barrel (snugly) and then secure with a few small plug welds that can be machined-out.

The barrel in the top of the illustration below is the goal. The second and third illustrations show how this sleeve idea would work.



What do you guys think? Do you see any issues or pending doom?

Thanks in advance...

As long as you have several plug welds and make the sleeve a press fit, that really is a great idea. What lathe are you using, is it a mini? Either way you may want to make or buy one of these holders for longer pieces.

I don't see any issue with your method.

Yes, it'd a mini 7x10. I'm thinking now that any investment in my lathe should be a replacement. I'm thinking I may be able to manage this one though.

I use a mini grizzly lathe, it works better than no lathe. You can get one of those attachments I pictured pretty cheap, they really help because these mini lathes have all sorts of chatter and vibration problems. I'm getting ready to make a 9mm barrel for an AR upper and I'll be doing a similar sleeve technique for the barrel extension.
