Hi Guys,
I am fairly new to turning so hopefully somebody can help me with this query.
How do I hold a tapered barrel from a 10/22 Ruger in the chuck so that I can shorten it and re-crown it?
The barrel will go through the head of the lathe no problem.
The barrel is blued so obviosly I don't want to damage the finish.
I look forward to some solutions to this problem.
Cheers
Mike

Mike,

An armorer friend of mine (who, sadly, passed away a couple of weeks ago) made a tapered bushing to fit the barrel taper at the appropriate spot.  He would split that lengthwise, insert the barrel, and then dial it in with a 4-jaw chuck.  As he reworked both M24 and various .50 calibre sniper's rifles for the U.S. military, I would assume that this was sufficiently accurate.

Bit late on this one but I thought it may be of some use to others.
For tapered barrel holding you need a setup commonly known as a spider. If you follow this thread on another forum you can see one in use.

Word of warning, when doing any barrel work it's always worthwhile indicating off the bore to ensure that everything is concentric. It's not uncommon to find barrel blanks with off-centre bores, the same applies to commercial barrels.

Brass shims can be used to avoid marring the barrel. To support the barrel further out you may well need a steady rest. For barrel work I recommend adding bearings to the fingers of the steady rest. These have lest likelihood of marring your barrel finish and are actually very pleasant to work with.

Abit late also.
For those where you cannot or dont want to remove barrel from receiver i usually turn a collar that fits in headstock providing support.
Ideally 4 jaw independant but bear in mind it may be true to the bore ie receiver end off centre in head stock.
Together with this if doing a few soft jaws bored with a taper!

If its only one for yourself might get away with 3 jaw self centring, wrap tape equally around the barrel and check for runout off the bore. Can pack each jaw to centre if need be.
Quite correct dont assume o/d is true many are not especially some Rugers.
