[QUOTE=Andrew Colglazier;479910]Inspired by Andy, I started putting together my own forge. Here are some pics. I'm still playing around with the air system. I'm using a Toro variable leaf blower, but on its lowest setting it's moving too much air.
I attached an old shop vac hose to the pipe into the forge, and while doing so it split in several places. That actually was a good thing as it let a lot of the air out. I also put a flap of plastic over the air intake, which cut it even further.
I heated up an 8"x.5"x2" piece of steel to non-magnetic in about 5 minutes.
regarding blowers...I've seen electric blowers used (like this):
also, here's a pic from Tim Lively's website:
Showing the cut-out in the forge (double-sided in his...only really need one side unless you're making swords)….and also a manual blower.
