and silver bearing flux..I packed the crack full of the heavy green
flux and zapped it with the tig..sealed it up well enough and I put a
slight layer over the area of the crack. After polishing it up with a
fine wire wheel, it looked good. But...is it?

How well does this sort of thing work with sintered metal parts?

Should I warn the guy to buy a new Widget? (Marlin just closed their
doors...so parts may become hard to find)

Any suggestions for other similar fixs with sintered metal parts?

Which part?

Carrier Assembly




On this one, if it fails, it doesn't look like there is much chance of
a major catastrophe. The weapon may become inoperable, but shouldn't
explode, or set off a round by accident.
But that's just from looking at the parts drawing.

With that caveat, the owner decides....

Personally, I'd order a new one.
