Hey mxm,
You don't understand. If the sides of the cell get hot, you're screwed. Forget the wet sand. Keep it clean and neat. I'd stay away from propane. Go electric. The iron I use looks something like this 110436914748 eBay item #, $5. Or something like they might use for stained glass lead work.
You can do what you want, but I advise to get reasonable tools and use a clean and safe set-up.
And for the straps, get some thin copper strips or braided copper ground strap. New, clean copper will work. Old crappy stuff will give you problems.
Regards,
major
