Re cutting the crown on an air rifle barrel.

Ғылым және технология

Hi guys today we have a vid on re-cutting the crown on an Airmaks Katran barrel, this barrel is a CZ one and the original crown was a little off center, in this vid we re cut it and test it. all tests were done at 50 yards and as always we are working on sub 12 lb/ft rifles. Thanks for watching.

    You can improve a rough crown by simply rolling 800-1200 sand paper into a blunt cone. Push the paper in the barrel 3-4mm and twist it back and forth 6-8 strokes. Rotate the barrel 90 degrees, repeat until rotated 360 deg. This will not fix a truly bad crown, but it will fix rough edges and burrs. It may or may not improve accuracy. This is a very conservative operation, and won't hurt the crown. Tip: Look at the crown with a 10x loupe and strong light before and after. You may see tny burrs that got smoothed off.

    Hello again, I'd very much like your opinion on what criteria indicator and specification being the most important parameter/s that make any barrel consistent and accurate. Would those parameters change depending on power levels? I'd be happy to hear your reply. Consistently accurate is the name of the game. Cheers

I have a precision lathe in the shed, gauge pins, an adjustable 5c collet chuck... as far as I can see there should be no problem doing this, just have a couple of questions on 'acceptable' runout and your opinions on tools for cutting.

    Can I ask how far past the transfer port does your riffling start, Does you pin push the pellet into the riffling or does the pellet sit in the smooth chamber.

    The rifling starts immediately after the transfer port the pellet is pushed into it via the pin probe, nice and gently the pellet is fully engaged with the rifling so both head and skirt of the pellet are in the rifled section. Thanks for watching

    @@sub12airgunners that's interesting, The rifling on my cricket tactical starts 15mm past the transfer port, the pin only drops the pellet into the chamber where it seems very loose, unless I use a longer slug, I would have thought it would be right on the end of the transfer port. Very strange.

    I have cut loads of them you just need to get a small enough tool or grind one yourself, I get mine from a place in the UK called Cutwel, they are called microscope boring inserts, I do have a video in which I explain the o ring grooves if you look on the channel for the Making FX .177 barrel Part 3 the transfer port and supports, that might give you a little extra help.

    Sounds more like the thread on the barrel rather then the crown, crowns normally cause erratic or bad accuracy rather than suppressor issues.
