73hemicuda Posted April 9, 2020 Report Share Posted April 9, 2020 (edited) I've had this thompson barrel in my extra spare parts pile. On the last section of thread, there is a section chipped off. Is this still serviceable? I've just held onto it for a while now, just curious as to whether it's still any good?

bigbore Posted April 9, 2020 Report Share Posted April 9, 2020 The damage visible in the chamber tells that barrel is no good for anything other than a tomato stake. Link to comment Share on other sites More sharing options...
Bridgeport28A1 Posted April 9, 2020 Report Share Posted April 9, 2020 Could be used for a dummy build. Link to comment Share on other sites More sharing options...

Black River Militaria CII Posted April 9, 2020 Report Share Posted April 9, 2020 Although the chamber walls have some damage which can be seen in the picture or what certainly appears to be striations from some sort of tooling that was used, the chamber can be bored out, threaded, a plug screwed in and the chamber recut. Not really cost effective for such a barrel given the availability of new Thompson barrels. Some day it will be cost effective. FWIW Link to comment Share on other sites More sharing options...
johnsonlmg41 Posted April 10, 2020 Report Share Posted April 10, 2020 I've fixed barrels much worse than that.......sometimes just for fun. I fixed a sten barrel last year that looked worse than that which was certainly not economically feasible. I've done others that are impossible to find on the loose. Odd or scarce barrels these days can fetch well over 1000 so putting some time and effort in can be worth it and it's best to test new techniques on cheap stuff. I'm sure if it were a Colt barrel answers would be much different. Link to comment Share on other sites More sharing options...
reconbob Posted April 10, 2020 Report Share Posted April 10, 2020 The broken off thread is irrelevant - does not affect anything. The mouth of thechamber needs to be smoothed/rounded in a lathe with a 0.100" radius cornerrounding tool. If there is no other damage ( I can't see any from the photos) thenit should be ok.

bigbore Posted April 10, 2020 Report Share Posted April 10, 2020 (edited) Your question was is it "serviceable" not is it salvageable. Anything can be fix with enough money, but you should ask how much it would cost to fix that used barrel in comparison to buying a brand new one for $99. . Some people have more money than time and will just buy new, while some have more time than money and can take the time to fix the old one.

I was holding onto it for a spare, but I'll probably end up buying another and just hang onto this one for now. Thanks Link to comment Share on other sites More sharing options...
