I thought I'd try something a wee might different (for me that is). I got real tired of building a fire in my "pit" and put off firing the blades that I'd layed up, so what's a guy to do?

It sort of tickled the back of my mind the other day when I was cleaning up the shop. "About 20-30 large coffee cans-- check. Some scrap pipe/conduit--check. This flange/ that dohicky--check..... I've got it!

Let's see, what to use as an air source.....Oh Yeah, that old oxygen concentrator from my Home Care days... That'll do-it! A trip to Wally World for some charcoal, and I can get started!

Oh boy did it work!! I was able to get 17 blanks up to non-magnetic using 2/3 of a 20# bag of charcoal.

Draw backs: the O2 concentrator has only 8-10 liters of gas out put at only 10-12 PSI (that brings purity of oxygen output into the upper 60%'s) so instead of blowing through and clearing ashes out, there were hot, or "sweet" spots that I would have to manuever the blanks to. I also had to fan manually from time to time.

Fix: I spent today disassembling the concentrator salvaging the compressor assemlby that has a raw output of over 100 l/m at 25-30 PSI. A little retrofitting to the "forge" should do the trick.

I'll post a follow up after I get the forge MK II fired up.

I hooked up the compressor and boy-howdie!, does that thing get HOT! I did one blade with it already, and the carbonized finish is beautiful. It sure burnes the cans up, though.

I'll have to start the MK III in steal andconcrete.
