Hand crowning tool to recrown barrel?

[Klem]

I've got an old knockabout rifle that has a few burrs on the crown, it's reached the point where I reckon it's affecting accuracy and should be redone but it's not worth paying a smith to re-crown it.

Buying a crowning bit for a power drill would be ok though. Haven't done this before, obviously doing it by hand doesn't have the precision of a mill or whatever a smith would do it on properly.

Anyone recrown their barrels by hand?

For $40 for the bits I'd give it a go assuming it's not a waste of time compared to a properly milled crown.

For a knockabout I'd say do it.

With a steady hand and a straight eye it's 95% as good as doing it on a lathe.

Pretty sure there in a YouTube video with what's-his-name from Midway USA where he shows you how to re-crown a barrel with hand tools.

Doesn't look like a big deal...

Larry Potterfield is who you're thinking of.

It's always a bit of fun working on your own gear.

Go for it

If you stuff it up,get the hacksaw out and have another go.At least youll know what your doin on round two.

Bet that's what all the bikies tell the cops.

"It's not a sawn-off officer, I just redid the crown a few dozen times"

I suspect they may see through that excuse

Actually, correct me if I'm wrong ,but I think you can get away with down to 16" barrel length. Accuracy won't be affected any noticable amount on a "knockabout rifle" at all.

Might be different in NSW. In VIC their are minimum overall length requirements.

I forget what it is off the top of my head, but if you had a rifle with a long barrel and short stock, and shortened the barrel. Even if the barrel was over X length, if the overall length was too short you'd be in trouble.

I vaguely recall it being something similar in NSW? Something to check I guess before you start sawing your rifles down

Yeah, the last bit there was what I was referring to.

Yep I went back to check it out cause ive heard of guys having to take 5 mill or so off to recrown. You just gotta not exceed these limits in NSW,not sure about other states but it seems to be in the back of my mind somewhere that this rule is nationally uniform.?

[AusC]

...not sure about other states but it seems to be in the back of my mind somewhere that this rule is nationally uniform?

I'd be surprised.

I really wish they would sort out a national firearms act and regulations.

I know there are some agreements in place between states like VIC and NSW that your license is valid in each state, but not everywhere...

It's stupid that we're all in the same country and no more than a few hours away from each other and there are different laws all over the place.

[Lorgar]

...not sure about other states but it seems to be in the back of my mind somewhere that this rule is nationally uniform?

You could be right. I'm going off the top of my head here...

Like AusC said though, there's plenty of differences state to state.

Maybe one day they'll sort it out...

How did you go klem?

Its not a .308 tool you are getting is it? I would like to shorten a standard rem 24 barrel down to 18 for a ute gun.
