Re: Magnumdeke's 1969 Starcraft Islander Restoration
OK, well, here's what I was thinking....
I'm not a welder, so, I don't know very much. But what I do know is that welding alum is a tricky biz. To get it right and strong is a challenge. Also, re welding really messes with the strength of the original alum material.
Anyway, if you would have to pay somebody to do it, forget it. The expense would be silly and no telling the welders experience/quality even if you did pay the price.
Now if you have the skills, maybe take a run at it. But, if it were me, I'd also run some mechanical means to make the repairs. In other words, alum patches, plenty of 5200 and closed end rivets, right over top of the welds too. Easy? No way. Those angles and ribs and stuff will make for some complex and tedious fabrication work.
IF you could get a solid weld AND a backup patch over the cracks/damage, I'd feel pretty good about moving forward.
If not........
well....
