there's a thread in swap and trade here:
barrels with holes linky

I knownothing at all about metal, barrels or welding, I'm just curious about this from an academic standpoint. Is this a legitimate fix for a set of barrels, not so much from a cost perspective (i.e. maybe not for this set, but maybe on a set of tubes with a higher value) but from a strength perspective? I'm curious if anyone has done this and if anyone has thoughts on it.
