How to repair/rebuild a metal control panel
Tailgunner:
All you need to weld a panel repair in place is two car batteries, a set of jumper cables, and a few paperclips. 8)
I did my panel repairs with a Miller TIG welder, but any of the small portable MIG machines should do the job.

I am working on my first metal CP.
I tried an alternative method to welding. I used "J B weld" instead.
I used it to cold weld a piece of metal under a hole and then filled it with bondo. I also tried the fender washer thing that OSCAR did (man that's a cool idea!). Both worked extremely well. :D
Sand flush and you're done. Everything is super solid. I had my doubts about epoxying those washers, but it holds fine.
So, if you don't have a welder, you can still cold weld. It just take 12-15 hours to fully cure :P
YMMV,
