    forge blower construction

    Have you asked around if any local A/C guys or plumbers had an old blower sittin around? Either one might have somethin like the first one. Or you could build one yourself using scrap sheet metal. Have you ever seen the inside of a hank crank blower? The blades are nothin fancy and would be easy to replicate somethin just like them.

    Is there a reason you don't just use a bathroom exhaust fan or somethin similar? I've had an exhaust fan hooked to mine every since I started and it works wonders and far much easier than tryin to build somethin from scratch and hope it works.

    thanks for the reply, building the blower wheel itself seems pretty simple.

    i forgot to mention that im trying to go for a no-electricity approach.

    Hi all,

    I am in the process of making a hand crank blower for my wood/charcoal forge which is approximately 600mm diameter and 300mm high.

    i have worked out a gear train setup that would give a ratio of about 1:20 using old bike parts. I have seen 2 blower wheels on Ebay, a 88mm for $8 or a 180mm for $30.

    As i am trying to do this as cheaply as possible, the 88mm seems pretty good for price. Roughly how well would the smaller wheel work if i could get it to 1000-2000 rpm?
