Planning the New Forge:
Ever since I started thinking about forging knives I decided that I wanted to build my own forge. This was for two reasons – 1: Because I’m going to appreciate something more if I’ve built it myself, and 2: Forges are EXPENSIVE! I think the cheapest I’ve seen was around $400 for a little farrier’s forge.
I know that I’ve already got an unfinished forge sitting neglected on a shelf but what I’ve had in mind from the very beginning is a forge built out of a propane/compressor tank (similar to the ones here and here). I’ve found a good number of resources online and settled on the design I want to use, and earmarked an air tank off a truck that I picked up at a garage sale for $15
Next, I’ll need to buy ceramic fiber for the lining and something to coat it with (Fiber Coat/Service Coat) so it doesn’t end up killing me (it’s carcinogenic and when left uncoated can shed small fibers).
The forge will also need a burner (or burners) to deliver the gas. I’ve found instructions for building a venturi burner on the Tharwa Valley Forge website and it looks relatively doable.
