So I have this frame that needs new seatstays. I removed the old ones which were mitered to seat lug and brazed with brass I think. Underneath the joint there are two about 6mm vent holes. I'm going to cap the new seatstays and silver braze them on lug sides. Naturally, this method won't cover the holes.

I thought maybe a smoothed MIG weld would be a relatively easy way? I have a friend who works with MIG, he could do it for me if it's appropriate way.

What do you think?
