I have seen the coffee can forges but wasn't overly impressed by the ones I saw online as they used some weird overly complicated DIY burner. Some didn't have a back on them to pass long pieces through which i thought was cool but the doors they built seemed clumsy.
I chose to use a Paint can but I used the bottom of the can as the front. I then created a plug for the back and attached it to what once was the lid. This lid can be removed to allow pass through.
I used a propane torch I already had on hand for some old plumbing jobs i did around the house.
I purchased the following items on line for $37 including shipping
Satanite Refractory Cement
1" Thick Insulwool, The smallest amount i could get was 2 sq' but I only needed 1 sq'
Empty Paint can from Home Depot for ~$5.00
I had on hand
a few metal bits from some old hanging file folders
A propane torch
Edit: I recently made a portable rocket stove for camping with the remaining insulwool but no Satanite as i thought it would break up and i didn't want the extra weight. The outside of that rocket stove gets WAY hotter than this forge so the Satanite is far more important than I thought it was.

I drilled holes and screwed it to the Paint can.

Does it get hot enough to do any annealing or tempering? (for blade work)
Can this setup, cement and Insulwool work for a glass blowing 'gloryhole' for melting glass?
Also, where are you getting your Insulwool? I'm in Australia and really struggling to find this product where I don't need to buy 10 meters of it for a rediculous price!
Cheers!
