A recently completed project that seems worth sharing…I inherited an old cannedy Otto blower some years ago from a shop clean out when a friend was moving. This poor old blower had lost all its gears and been converted to a belt drive from an electric motor. I needed a hand cranked blower for my portable forge so I piddled a bit with different ideas. Chain sprockets seemed to have potential… then we went through a half dozen gear motors at work in a short span…this is a gearbox off of a sew gear motor. The foot broke off, but it was otherwise perfectly good. It took a bit of fiddling to get it to run, but it actually works pretty well. The original gears would be better of course, but this just bolted into the old gear housing

Now that is really ingenious thinking, I'll have to remember it when I run across another blower that needs gears that are impossible to get.
