Hand crank blowers are under appreciated in today's marketplace. Most of the ones you will find for sale were made between 1890 and 1930. In general they were very well made products built to last. Most of these antique tools are still in great working condition and priced reasonably. The best prices I have found are from blacksmiths.
Antique dealers are the highest.
Ebay has a half a dozen of them on auction at any one time. Every Neo-Tribal Metalsmith ought to own a few. The Champion 60a blower is more than enough power for this forge and is easily cranked. As you can see this forge gets plenty hot burning the natural charcoal and even welding temperatures are easily achieved. There is very little smoke when burning natural charcoal in this forge which makes it usable where you could never use a coal forge.
