I was looking at getting a set of iron OIF A65 barrel (71-1033) bored and whilst trying to work out their current oversize, noticed some marks in the bore. Turns out this mark is also visible on the outside, below the bottom fin and the flange. As it stands you couldn’t reliably bore it and expect all to be ok.

Before I send it to the gods of vintage BSAs, is this Repairable?

I’m thinking have the area welded, then have the bores sleeved. Or is this just like playing Russian roulette?

I’m happy either way, I know for what the work would cost I could get another barrel for that amount. I’d have been much happier this being a good barrel of course. But sadly I don’t have that luxury.

Scrap, not worth the trouble. They are plentiful enough.

I've gone through the exercise of through bolting and lining a barrel before
but it's a lot of work or expensive if you farm it out.
Once the wall thickness is small they loose strength so need through bolting,
that has to be done carefully as it is on an angle.

EBVC has a +20 on ebay at the moment, better to get that bored than mess
about repairing the one you have.

My first A10 had a crack like that ( from a jamed rod ) that eventually ran completely around the flange allowing the right side to lift about 1/4" each stroke
Which caused the muffler mounts to break and the muffler to swing out & in .
A some what interesting ride ( push ) home .
So toss it
Good news is cast iron scrap prices are going up .
