Bigcity Posted October 31, 2009 Share Posted October 31, 2009 (edited) Ok guys my brain has been working overtime on this one i have not made this yet but i thought it would work i attatched a sketch on a blower mechanizem that uses the recoil starter,flywheel and or not the cranksfaft of a normal small engine or lawn mower engine its basic and i think could be modified for any forge:) i hope this helps and i hope you can see it Edited October 31, 2009 by bigcity Quote Link to comment Share on other sites More sharing options...
minceyjs Posted December 22, 2009 Share Posted December 22, 2009 Very cool. I've got access to tons of lawnmower parts, but I'm not getting the whole idea of your drawing. Could you provide some more information in detail. This may solve my blower problem. Thanks. Quote Link to comment Share on other sites More sharing options...
Bigcity Posted December 23, 2009 Author Share Posted December 23, 2009 its kind of a rough drawing but its based on a rivet forge blower the one that has a lever you pump and the flat belt blower assembly the idea i had was that you could use an old crakshaft or make your own shaft for the flywheel and drive pully assembly use an old flywheel and a recoil starter with a return spring so you can pump the lever to drive the mechinizm Quote Link to comment Share on other sites More sharing options...
48willys Posted December 23, 2009 Share Posted December 23, 2009 You can try it, but I really don't think that the recoil will take it to well. You might be changing the rope and spring to often. The crank won't be balanced so you would need to make a shaft, but that might not be bad if you can use an old flywheel as a swage to make the taper on the shaft. You might just try it and work the bugs out as you go. Also you might be thinking this way already, but I would start with the largest flywheel you can easily find like from 11-16 hp motor.

ThomasPowers Posted December 23, 2009 Share Posted December 23, 2009 Seems like a set of bike gears and hub would work too. However I see no real virtue in the pump blowers over the crank ones so why go to extra work to reproduce one? Quote Link to comment Share on other sites More sharing options...
pkrankow Posted December 23, 2009 Share Posted December 23, 2009 Having the ash dump integrated into the blower adds complexity that a piece of flexible exhaust pipe can easily resolve. Having the blower somewhat freestanding also makes it easier to transport and useful on different forges. Phil Quote Link to comment Share on other sites More sharing options...
