How much does it cost to build a propane forge?

Expect to spend $100-150 for building a GOOD forge. Adding temperature reading and control can run an extra $100 or so, but can be added later. I would build in the TC sheath when making the forge, though. A well built forge will last many, many years of heavy use, and can be easily sold if no longer needed.

How long does a propane tank last on a forge?

3-5 PSI will last me 35-40hrs if I am diligent about using the idle circuit. I sometimes don't have to fill my tanks for a month or two. My small forge is a 6×10(3×10 cavity) and it'll last 20+ hrs on one 20lb tank. My main forge is made from an old propane tank.
