    Default The right tools - Barrel Crowning

    Now that I've got my lathe, I have the cutting and re-crowning of barrels sorted. I cut the barrel with a small angle grinder using a thin grinding wheel. This is a very quick way and allows little heat build-up. Then I put the barrel in the lathe to true-up the muzzle. While it is turning in the lathe I twirl a 6mm ball-headed mini cutter held in vice grips around in the bore. This method really gives a nice even crown. Then I finish it off with a rubber polishing tip just to remove any burrs. Finally a bit of bluing and you're done.

    Ou Van,
    The next step is to get the crown 11 degrees, (I'm told) for even superior results.

    I don't know how I'm going to get the 11 degree thing figured out, but I have to say so far both the rifles I've chopped and re-crowned are shooting sub 15mm groupings at 30m without trying too hard, something both rifles could never do before.

    Dis hoekom ek gevra het of jy al die draaibank gekry het. Ek dink sterk aan 'n knaldemper vir my QB78D.

    Van, slip on silencers is k@k van die duiwel. Het een op 'n CZ200S gedad en hom die eerste dag van binne stukkend geskiet. Aanskroef tipe is the way to go. Net gedink mens kan dit vir goedkoper self maak (en 'n beter produk)

    I just would never have thought of cutting a barrel with a disk.

    Job looks pretty good though.

    I would like to hear how you did the blueing .I would like to re blue my springer barrel.After shortening it too

    Trial and error. After using many products I found one that really works. It's called Klever Schnell-Brunierung. It's a cold blue but it lasts, and can be polished after it's been applied. You have to make triple sure the metal is clean before application. How did you cut your barrel?

    Cor: just a small correction. The slip on Silencers made by Air Arms for the CZ200 rifles works very well and has no effect at all on accuracy.

    I will agree that the locally manufactured slip on silencers were never the best.
