I bought a rifle 2nd hand that appears to have a minor bend in the barrel.
I'm after a recommendation for someone who might be able to straighten it.
Any gunsmiths close to Auckland?

Shane Longney in Te Puke did one for me a few years ago
David Dwenn has retired. If the rifle is worth bugger all then I'd take it to reloaders or GC. The hassle of courier to Dean Maisey may not be worth it unless it is specialQuote:

There was an old one about in one of the ww2 factories. Had a big flywheel press for straightening barrels. Old mate doing them quick asQuote:

If you know someone with either I can tell you how to do it
Really quite easy if you have a good eye
But there are a few tricks
You could get a horse to roll on it. That bends barrels.
Should say Fly Press
Quad bikes are good at bending them tooQuote:

Get it to roll in the other direction thoughQuote:

Used to thwack them on a timber block, but it was a learned skill how much thwack to thwack with - least you bend it too far and end up with a pretzel.
How much does a slight bend matter?
Saves adjusting your scope. Leave it where it is and bend the barrel to suitQuote:

If its a curve then I would have a go at straightening it in the vice with padded jaws.
If its more of a sharp kink-bend the you will need a fly press and someone who knows how to operate said press.
I am actually not too sure. If you search for the clip you should find the older gent who was demonstrating the technique using a big block of timber and said barrel held by the muzzle and thwacked at the outside point of the bend over the block of timber. Was eye-opening to say the least. Bang, check, bang, check and twist, bang - pronounced good to go.Quote:

The barrel has primary membory of where it was when it was straight and goes back to straight more easily than to bend.
H&K still doing ALL the 416 barrels hammer forged rifling and using the same technique to straighten them.
Most likely the same machine as in the Mauser factory considering they picked up the left overs from Oberndorf.
Bloody krauts!
that must be the one i sawQuote:
