Re-crowning a barrel

I'm interested in one of these...

Neat.

Obviously the answer is to buy the kit and offer everyone at your club a re-crown for twenty quid, pays for itself in no time :)

I watched afriend (gunsmith) re-crown a Tikka T3 barrel while still attached to the action. In layman's terms, i.e. those I would understand, the barrel is passed right through the lathe and into the chuck from the outside, so it is the barrel length which determines whether or not this can be done, i.e. how much longer is the barrel than the distance from the outside of the lathe to the end of the chuck - clear as mud?

I did think about that to be honest...

I've watched them being used (youtube) and it makes perfect sense.

I'm sure you can line up the lathe so it cuts concentric to the bore, although I imagine it's timely and a faff, and most crowns would be cut to the assumption that the bore runs concentric to the barrel. This tool uses the bore as it's centre point, and lines up the tool in the bore. A brush inside the barrel stops swarf enterring the breach from the muzzle end and cuts are made.

If it wasn't $360 I would have bought a kit already as it seems like a great long term investment.

I would not be unhappy with a gunsmith providing this method as opposed to having to set up in a lathe. Your mileage may vary, and I'm sure certain people would swear by the lathe method...

There are cheaper versions, but the Manson is about the best available...

Saw one of those being used by probably the best gunsmith in the world, at the back of the firing line at Camp Perry last year. A shooter dropped his rifle on the muzzle in the carpark and was going to retire from the comp until said gunsmith offered to re crown. Job was done and shooter went on to finish In the top ten of the US Long Range Champs. I know of two well respected gunsmiths who use them without any issue.

And there you have a brilliant recommendation :)

Almost exactly like that, with a "spider" holding the barrel at the rear of the head-stock

Yes you need to support the bit with the action on otherwise it would just whip about as it spun. You would use a barrel spider to support it.

Thanks for the big print version! Yeah theres no way the gun i need re-crowning could allow that Oh well, back to daily unanswered phone calling then!

what rifle is it Mark?

Its probably the other end of the spectrum from what you want to recrown but I did my Mosin Nagant with a brass drill attachment I got machined at work and some valve grinding compound and it did the trick very nicely and made a vast improvement to how it shoots.Admittedly the Mosin only cost me £150 so there was nothing to lose really.

My VZ58. CCA rang back yesterday and its being collected on Friday FoC to be looked at

I took my M91 Carcano and Type 38 Arisaka to a local gunsmith, sans timber and he re-crowned them both without removing the barrels.

He made an excellent job of both of them and the groups have tightened up noticeably.

Ah yes, quite a large square action to fit into a headstock
