a ' DIY-barrel-turn-down kit'?

[cpileri 0]

Is there such a thing as a ' DIY-barrel-turn-down kit'?

or a 'lathe alignment tool'? Similar to the thread aligner (example seen here:http://www.brownells.com/aspx/NS/store/productdetail.aspx?p=22229&s=47995 ), but where you slide the caliber-sized rod down the barrel up to the wider part which is a known diameter: say 15mm in our case. Then instead of a threading die, a 'milling die' or a 'grinding die ': one designed simply to shave off metal down to the 15mm diameter we desire, is cranked down and turns down the barrel, keeping it even and true to the bore?

 

Or, is there any good, accurate way to turn down a barrel at home?

 

(FWIW: I am trying to turn down approx 1/2 of an inch near the muzzle of a barrel which tapers from about 16mm to 14mm, down to a uniform 14mm. Yes, the same one referenced here: http://forum.saiga-12.com/index.php?showtopic=11413)

 

Thanks Experts!

I had the same thought... the normal method is to press the barrel out and place it on a lathe and mill the end.

 

You've seen the little jigs that are used to trim case necks on brass? Something like that only bigger would be just the thing for this application.

 

Even simpler, doing it the same way that a pipe cutter works - only instead of a cutter, a milling device (mill file section) - should be able to produce a good-enough result...

When I did my WASR-3 to fit a 1/2 - 28 die, I used the die on a TAT to mark the end of the barrel, then filed, ground and sanded a little at a time until it fit, checking often.
