I built a hand crank blower I was in the same boat. There is a pic under my photos. It has to be reworked looking not high enought gearing. Looking at a bellows you can make one out of plywood, canvis, and rubber roofing paint pretty inexpensively. Granger has a dayton blower #99080464 it is Electric I have used the same one for the last 5 years works great and for $65.00 you cant beat it
