    I decided the only way to turn the completed front section would to be in a "socket". The section sits on a shoulder on the nose and is secured with a setscrew

    turning ID of socket








    Next up is some stock for the body of the tube. I found something that was close in ID and OD.

    Boring in lathe.



    Before I committed to having a overly long piece I had to cut the barrel lugs (and blocking lug for SBR)



    modifying barrel (now extended) for blocking lug






    After that the blocking pin preventing a FA bolt from going into battery






    In socket ready to be turned



    turning shoulder





    Tube section shrunk on



    Complete tube in lathe and tacked. Although I do not recommend welding in a lathe, it seemed the only way I could hold everything straight without building a fixture. If you do this use a TIG, If any other process cover everything with aluminum foil to keep the spatter from damaging, most important is to keep the ground as close to the work as possible and never crossing a bearing.



    parting to final length




    starting to turn OD

    Some people are like Slinkies. Not really good for anything, but they still bring a smile to your face when you push them down a flight of stairs.

    I have no clue. Its been 4 months so far working on it here and there, while other machines are running, etc. All I know is $180 is cheap for a pre made tube

    I couldn't agree more. I keep telling myself I'll just buy a tube and make building one a weekend project, but I have too much time on my hands anyway.

    CaVALRY,

    your making nice progress and it looks good!

    but im also glad to see you say that the $180 is actually a good price on one of these tubes cause most people just dont believe how much work goes into one of these builds until they try it.

    I NEVER DID EITHER.

    you'll love it when its done.

    So true, A project like this seems to always show a need for a jig or some part to be made to protect the part in the lathe or ?. But The fun of doing it and the satisfaction of a job well done is PRICELESS

    I also agree that 180.00 is an excellent price.
