My project plane (wooden plane) has a .063 steel bracket made of 4130 that mounts the horizontal stabilizer to the vertical fin. It's quite a complicated bracket and would be difficult to remake and mount since the aircraft is already skinned in plywood. A few of the holes have been mis-drilled (looking like elongated bolt holes). Can these holes be welded up and re-drilled? Is that a feasible repair in the aviation world?
