@bchapp Epoxy typically unbonds with moisture and heat. I use this epoxy on knife handle making specifically because it is used for boating applications so I know it is okay with some moisture. It could work for you http://www.westsystem.com/ss/west-system-launches-g-flex-epoxy/

Yeah torches aren't too expensive. This kind here is self lighting:
Go to the hardware store and get the yellow benzomatic cans. It's a good item to have anyway. With propane gas it is good for bruleeing, starting charcoal, etc.

It is a different type of flux than used on copper, but you can solder stainless http://www.wikihow.com/Solder-Stainless-Steel
