Thought this would be fun to post when it was going.. This is how i heat treat knifes primarily.. Some stone coal of some sort. Grill briquettes to start em, some engine oil to keep it burning while the coal lights.. and a vacuum cleaner for air.. The thingy is a break drum sitting ontop of a cast iron flowerpot i stoal from the wifeys garden and plasma cut a hole into it.. (that was a fun discussion). ;)
And on side note, this setup melts steel.. really fast.. i have blinked once or twice and the damn knife blade came dripping out through the bottom hole.. And its really hard to "eyeball" the temperature most times.. so i put it in there for a few minutes and hope i can pull it out more or less. =)
