    .32 caliber problem

    Post by tkerrigan on Tue May 31, 2011 2:36 am

    I just acquired a .32 caliber barrel and breech with bolt to go on top of a discovery tube. Measuring the barrel, it is .500" OD. the barrel bore in the breech measures .509 ID. If I tighten setscrews to hold the barrel in as it is, the barrel will be squeezed out of round. There is not room to bore and sleeve the breech. I'm thinking some .003 or .004 ss shim stock around the barrel stopping just short of the transfer port. I'd like to use brass because it's more flexible, but I think it might cause corrosion.
    What say you?? Any ideas will be appreciated.

    Tom

    Not too sure using shim stock is a great idea, is there a way you could turn the barrel down slightly and sleeve it, it would be a much better solution and permanent, good luck and all the best, Neil.

    Sleeve

    Post by tkerrigan on Wed Jun 01, 2011 10:38 pm

    I don't know, with .308 bore and .500 OD, disaster could be just waiting to happen. The sleeve and the barrel would have to be awfully thin walled and both would be hard to make. Especially as I would like to have SS between the aluminum breech and the steel barrel since it has to be done anyway. I'll try the shim stock first, and if that doesn't work out, I will be able to try a sleeve later. I think I attached a picture of the muzzle end of the breech, the thin spot is .052", the OD of the breech is .830".

    What about reaming out the breach and putting a sleeve in there, is that possible? I know what you are saying about the wall being thin but you are not dealing with the kind of pressure you would have with a fire arm, but it is always best to air on the side of caution. Good luck with the project, Neil.

    The nice thing about the small diameter breech is that the hammer follower pin can be short, should be easier to cock.

    32 cal barrle

    Post by buda13 on Tue Jun 25, 2013 10:36 pm

    New to the form  & the easy way to fix the
    is to bore the breach port  and add the SS. sleeve
    leave the sleeve thick and press it in , then bore to fit
    , this way you will it will hold the pressure affraid

    Amazing

    Amazing coincidence, I ended up sending the parts to Sean Stephens (workinman), as he makes scads of this type of rifle.  Just came back about two weeks ago.  Shoots good.  Regards, Tom
