This latter seems interesting. I'll need to concoct a furnace for starters. With the strapping so thin, it seems to indicate the sealed into a tin with charcoal time would be pretty short, no more than 20 minutes. The bending jig would also seem to be easily made, then it bent on the mill with a custom tool I could make. It'll keep me out of the bars for a month or more I expect. And likely generate more questions later. I also ordered another similar one (again, but might not be the same one) from gun farts. About $18 w/shipping. We'll see how if fits before rounding up a bit of strap and a furnace kit. Thanks. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
