A How-To on how to make a small forge
Clay- From a potters-shop
Fan- From one of those tacky inflatible palm trees
Metal Chair- I got one from a junkyard. Stacked bricks will also work
Safety Wire- $5-$10 at hardware shops
Big Speaker- Found an old steel one at my church as well
Quickcrete- $3 on sale
Light Fixture- Got an old one from my chicken coop ($5 new)
Steel Pipe- Easily found at a junkyard/scrapyard. Be cautious: I unwisely used galvanized steel. Though the dangers are exaggerated, if used in an enclosed space, can be pretty rough.
Tire Rim- can be found at a junkyard too.
A Hack Saw- Every man should have one of these
I think that covers it- on to Step 2
