the iron dwarf Posted November 6, 2016 Share Posted November 6, 2016 anyone here made one? did it work well? was it easy to make? I can see 2 areas of concern 1) gearing to get required speed 2) making an impeller that is suitable I am looking into both of these at the moment and I have some ideas to play with, for gearing I know of a source of geared motors that may have a suitable ratio, will be checking that out when I can and will also have to check the gearbox is removable and can be turned by the output shaft, if it is worm and wheel it cant. for the impeller I was thinking of laser cutting it and making it self jigging Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 6, 2016 Share Posted November 6, 2016 Making do; basic things for simple living by Arthur M Hill has one in it; but I can't swear to it as it's at the other house....They were using bicycling gearing I believe. Frankly I believe a homemade box bellows would probably outperform a home made centrifugal blower Quote Link to comment Share on other sites More sharing options...
Norseman C.B. Posted November 6, 2016 Share Posted November 6, 2016 There was a guy on this site a couple years back that was making them and selling kits or whole assemblies, his handle was something duck or duck something .... Quote Link to comment Share on other sites More sharing options...
Glenn Posted November 7, 2016 Share Posted November 7, 2016 There was a fellow on the site making a blower from 55 gallon drum metal. Had some interesting ideas and designs. Quote Link to comment Share on other sites More sharing options...
caintuckrifle Posted November 20, 2016 Share Posted November 20, 2016 The best bet is probably going to be to build something along the lines of the old frame type blowers with the frame, large flywheel, and the low mounted blower unit. I seem to recall an African made blower constructed in such a way. This one used a bike tire. Quote Link to comment Share on other sites More sharing options...
the iron dwarf Posted November 20, 2016 Author Share Posted November 20, 2016 still awaiting a batch of geared motors that turn up at the local scrapyard so I can see if the gearbox is removable and will work Quote Link to comment Share on other sites More sharing options...
Glenn Posted November 20, 2016 Share Posted November 20, 2016 Think about what used gears and is thrown away on a regular basis. Bicycles come to mind. While they may not be considered heavy duty, they are expected to last the life time of the bike and transfer power from the crank to the wheel and propel the weight of an adult male for many hours or miles. And not just the crank / gears, but also use the tire as it will convert one revolution to a greater distance due to the diameter and circumference.

Charles R. Stevens Posted November 20, 2016 Share Posted November 20, 2016 I would side with TP on this, a box belows or a constitina bellows made from a inertube would be easier to build and somthing soothing about using a bellows. Quote Link to comment Share on other sites More sharing options...

Yeah that's the guy, If he's still around here shoot him a PM, I watched him develop the stuff in stages on this site and it looked good ....
