    Suppressor threading

    Having recently moved to Auckland I need to cultivate some useful contacts again.
    Does anyone have a pet gunsmith or experienced AND competent turner to recommend for threading a barrel fit a rimfire suppressor?

    It's a fancy KIDD barrel and I don't want to take any risks.

    Was considering sending rifle and new barrel and suppressor to Cleland - get some trigger tweaking done too.

    I've had good service from Roger Spackman at Sub-Silent Suppressors.
    He has a dedicated lathe he uses just for threading barrels.
    As a bonus, he is Auckland based. Might be worth talking to him about suppressors while you are at it.

    "It's a fancy Kidd barrel so don't want to take any risks" would probably rule out the above option

    I can't speak highly enough about Scott Trail at ssrnz, this would be a very simple task for him.

    Scott Traill is excellent but of course not in Orkland.
    MAE did a superb job of threading on semi 22 for me. Not sure though if they just do threading - my threading was combined with the purchase of on of their suppressors.

    Couriering a barrel may be cheaper than driving across dorkland I guess

    If you do not need to get this done in Auckland, then +1 for Scott Traill at SSRNZ

    I wouldn't have a problem driving across Auckland to MAE but certainly wouldn't do the same to get to RR's

    Alan Reid Toolmaking in Ellice Rd, on the shore, done some work for me.
    Really happy with his work.
    He nui to ngaromanga, he iti to putanga.

    You depart with mighty boasts, but you come back having done little.
    Sounds like a typical hunting trip !

    Here is a bit of information regarding kidds barrels:
    The original blanks are from Lothar Walther in Germany.
    The guys at kidds receive the barrel blanks, check them, take a good amount of time to "taper lap" the barrels so that the bore is slightly chocked toward the muzzle. This is a really an important step to get the best accuracy out of a 22 long rifle. The best 22 hunter benchrest rifles in the USA all have that chocking taper toward the last few inches of the muzzle. Even Anschutz barrels are manufactured like that.
    Now when you start removing some material from the end of a barrel to make a thread, the internal bore dimensions at the muzzle can open slightly , and more so for button rifled barrels like the lothar Walther ones.
    When you buy a factory threaded barrel from kidd, it has a recess inside the thread so that the muzzle crown is inside the fat part of the barrel. The guys at kidds know perfectly well that they could not guaranty the accuracy of their factory threaded barrels if they were crowning the muzzle at the end of the thread like it is common practice.
    Please take look at my kidd barrel muzzle which was factory threaded (1/2"-28):

    There thread is cut exactly to the dimensions, and my suppressor (1/2"-28)has a nice tight fit on it. That is one solution that works.

    The problem with the standard thread for 22's (1/2"-20 in Europe and nz, and 1/2"-28 in the USA) is that it takes away to much meat at the end of the barrels specially when done on a varmint type barrel.

    Now, there would be another solution. That would be to have suppressor made with a much wider thread or even a custom thread to match the diameter of the barrel you intended to get threaded.
    On my kidd barrel the fat part is 23.4 mm diameter. A custom thread of 21 mmX1mm pitch or 0.875"X20 or 28 TPI would leave enough shoulder for the suppressor back end to stop against and would allow to remove very little meet from the muzzle end which in turn would keep internal bore dimensions correct. Of course this a more expensive way of fitting a suppressor as all the work and machining time is charged up.

    I know millions of 22's worldwide have had there barrel cut and threaded for 1/2" type threads and are producing an accuracy from golf balls diameter or better at 50 m which satisfy most of their owners when they want to shoot rabbits size game.
    But if you want the ultimate in accuracy with your 22 ,you now know what needs to get done.

    If I was you I'd get HRE to build a custom suppressor with a larger thread.
