- 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.

I could watch these vids of yours all day ... ABSOLUTELY fascinating stuff ..
Thanks, good to hear glad you are enjoying the vids. Thanks for watching.
what can you say ..NOTHING!
attention to detail and quality of workmanship is first class as always 👍
Cheers mate, a simple yet effective crown does the job. Thanks for watching.
Another great video…As usual. I love the look of that simple, functional crown. Have a good one.
Cheers, we used to go fancy but found in the real world tests it provided no additional benefit, so we stick to these now, Thanks for watching.
Another great video jake , there's so much time that goes in to all you're work but I think it's the quality of you're workmanship that needs the time and effort you always put in .
Cheers Phil, glad you liked it, appreciate that mate. good shooting in the comp, Thanks for watching.
Awesome video ... once again great job 👍thanks for sharing these are the videos I like to watch so I can get some tips and info on how to make my rifles better ty
No problem, glad you enjoyed it. Thanks for watching.
Thanks Jeff, that is very interesting, great video as usual.
Cheers glad you enjoyed it, Thanks for watching.
What a wonderful job! Congratulations, guy.
Thank you very much!
Yes another really good video I envy your knowledge and expertise ….respect 👏
Cheers glad you enjoyed it. Thanks for watching.
I really like your complete tools to perfect a rifle to make it more perfect
Thanks
Come on, who shot the target!!!! 😁😁😁😁 As always , good video.😊
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.
Yep another good tip, especially if you don't have a lathe, Thanks for watching.
Another excellent and concise video there with some expert lathe work. Thanks for showing us how it should be done 😊 👍
Cheers, much appreciated Thanks for watching.
Great video
Thanks for watching.
Ever used a muzzle lapping tool to refinish an existing crown? Any chance of a video of that and before and after results?
Yes! A dremel! finally something I could have a crack at.....oh wait....no lathe. Doh! really clear video and something you call simple would have me scratching my head for months! I was waiting for a burst of Frank Sinatra (my way) though 🙂 Love these videos!
Cheers Tim, glad you enjoyed it. Thanks for watching.
Awesome.
Thank you for sharing. 👏👏
It’s a shame to hear that you also suffer from other shooters aiming at your targets.
I get this every single week.
Thanks glad you liked it, yeah its a little annoying, but what can you do. Thanks for watching.
super cool video
Thanks!
Great precision machining, The results are the proof👍🏼
Cheers great little rifle this one, really happy with it so far. Thanks for watching.
gracias
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
Does it effects on your accuracy and distance?
Фасочка на заглядение!
It's not only a matter of the pellet leaving the crown cleanly, it also needs to leave the crown evenly around the entire circumference.
Yes i agree 👍
Excellent informative vid 👌 I'm struggling to get good accuracy out of my vulcan 2, maybe my barrel has a bad crown. Cz barrel
could be 😀
Off topic I know, out of interest how would you go about machining an o ring groove inside a .22 barrel. Thinking about try to machine one out of a barrel blank but not got a tool small enough, just wondering if you had done this
Thanks great video as always 👍
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. Thanks for watching.

@@sub12airgunners thanks 👍
@@sub12airgunners think I’m best off buying one cos if I try grinding a tool that small the geometry will be well off…!
@@Airgunfunrich Yes I gave up on grinding ages ago now, carbide does the job much quicker, although it does hurt when you break a £30 bit. thanks of watching.
@@sub12airgunners know exactly what you mean! Keep up the great work 👍
Hello, random question, do you know if the STX barrel system from an impact will fit onto a dreamtac without the shroud is this possible, I'm looking to stiffen up my dreamtac barrel, many thanks
Yes should do no problem, the barrels should fit. Thanks for watching.
How can I contact you? I have a new Styre Pro X I want to thread and re crown, looking for advice. 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.
Jake just a quick wear can I buy a new blank barrel from Bri.thanks videos are great
Hi i get them from Chambers gun spares 😀
@@sub12airgunners thank you Bri.
G'day, any hope for us expecting and answer regarding accuracy and what's important? See my previous question below.
Another amazing video sir 🫡
Cheers much appreciated. Thanks for watching
hi, what lathe do you use? can you recommend me some good budget lathe for hobby use?
I use the Warco GH1230, a nice lathe although a bit big for hobby use, I started off with the WM180, lots of people over the world re-badge it, and I highly recommend it, cheap enough to try the machine work out and sturdy enough to do most small jobs, its not perfect but good enough for making small parts. Thanks for watching.
Thanks its now my choice too:)
A good little simple and effective crown, can't go wrong with it. Thanks for watching.
@@sub12airgunners I am looking for rotary tool holder any thing that you might recommend or I will have to make my own one LOL? I watch with jealousy how this big chuck spins nicely. I fight on my Chinese mini lathe I had make it work if you know what I mean. Great content keep going well done.
Do you service airguns for other people?
Unfortunately not, we only work on our own rifles. Thanks for watching.
have you ever had a bad crown but the rifle was very acurate but when you put the supressor on it would destroy all the baffles
Sounds more like the thread on the barrel rather then the crown, crowns normally cause erratic or bad accuracy rather than suppressor issues.
Mantap bang👍👍👍
Thanks for watching.
Great work & explanations, as always. Thanks gents, great videos.
Does the grinding dust getting on the lathe not worry you a little?
Yeah I didn't show it but after grinding we always do a full clean of the ways, we are not grinding 24/7 so its a little here and there but the dust is removed asap. Thanks for watching.
I do this
😁
Thanks for watching
