I know this is not a traditional building technique, but I don't have a better idea. I have a very nice forged trigger guard that a guy gave me at the CLA show last year. It was broken at the front of the bow where it makes the bend to the forward mounting base. It has been repaired, but there is a crack and not enough metal on the front side in the corner between the bow and front base. I was thinking about welding a fillet in with my wire welder and then dressing it down with files. Will I have any problems with the finish on the welded area? When I'm done, there should be very little weld left. Just a small fillet in the bend area. I'm planning to do an aged finish using cold blue and clorox.
