John Martin Posted August 22, 2008 Share Posted August 22, 2008 I was wondering if it would be possible to convert a electric Champion 400 blower to hand cranked. I.E. taking the electric motor off and assembling a handle to attach to the shaft. And then converting back to electric. It would save me $100 to get another hand-cranked blower. Sorry if this post seems completely retarded. But I had to ask. :) Link to comment Share on other sites More sharing options...
Sabre Posted August 22, 2008 Share Posted August 22, 2008 well i have a mini transmission for a go kart (toy) that you spin one shaft slow and the output spins fast...you would need something like that...you would prolly need to make a bracket that bolted on and off and then you could interchange... i think its a really hard job for anyone to do but i dunno....

Dragons lair Posted August 23, 2008 Share Posted August 23, 2008 I picked up a no name blower at the flea market. Had a flat belt pulley but the seller had added a hand crank. Only has 2 blades and with no gearbox you can't crank it fast enough to equal motor rpm. ken Link to comment Share on other sites More sharing options...
Finnr Posted August 23, 2008 Share Posted August 23, 2008 John . the most logical thing to do would be find a gearbox like was taken off that blower o many decades ago when some smith in Western Wisconsin went all modern and electrified the blower. Which I'am thinking is going to cost you more that a different blower. Finnr Link to comment Share on other sites More sharing options...
welder19 Posted August 23, 2008 Share Posted August 23, 2008 Why do you need both, electric and hand crank? welder19 Link to comment Share on other sites More sharing options...
irnsrgn Posted August 23, 2008 Share Posted August 23, 2008 (edited) put a flat pulley on it that is knurled to prevent slipping and use a 12 or 16 bicycle front wheel against it to drive it by hand. You can add this the the motor shaft and make the bicycle wheel removable this will give you a 12 or 16 to 1 ratio if the pulley is 1 inch diameter, ie: for every turn of the bicycle wheel the fan will turn 12 or 16 times. The free turning elect motor will act as a flywheel. Edited August 23, 2008 by irnsrgn Link to comment Share on other sites More sharing options...
