I Forge Iron

making a hand cranked blower


the iron dwarf

Recommended Posts

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

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.
