Rob.Wilson:
Hi Wes
Watching this one with interest ,,,,, did you get a chance to give the process ago on the gun parts ? :)

A question, if I may.
Folk make their own case-hardening charcoal from bones, leather or hardwood, rather than simply using powdered barbecue charcoal. What are the advantages of making your own? I realise there must be advantages, or people wouldn't bother doing it.

Whats in commercial charcoal? Glue? Fillers? lighter fluid? clay? They have a lot of extra "stuff" in them. This way I know what I'm working with.
A local guy makes Black powder. The main ingredient is charcoal. He started out using charcoal briquets.. The stuff he made worked. But it wasn't very potent. He buys unprocessed charcoal now with good results.

Thanks, Wesley; point taken.
A UK ad for "restaurant grade charcoal" says "Unlike most mass market charcoal, this is totally free from binders, accelerators and any other additives such as coal dust or sodium nitrate used in mechanically processed factory made charcoal", so that would probably be OK. It's GBP24 (~$36) for a 10 kg sack, though, including delivery.

Powder Keg:
Yes. That would probably work. I think it is cheaper to make your own. If you can find the stuff. The hardwood is scrap from my projects. Leather was free from guys from work. And I got enough bones to fill my can twice from my uncle. I'll pick up some more next time I'm over there also:o)
After the holidays I plan on crushing my charcoal. Stay tuned..... I have a plan :proj:
