The plastic hand crank handle on my compost grinder just broke, and the company that made it is long out of business. I'm trying to see if I can find some other replacement, but I'm having trouble searching for something that would connect correctly. The male metal part in the picture below is a semicircle 3/8" in diameter, and protruding about 7/8" out the side of the device.
I could just use a vice grips as a crank handle, but I'd like something a little more elegant.
Can you suggest some search terms that would help me find a suitable female part to match this? I've found some oven knob replacements that talk about "D-posts", but an oven knob isn't going to give me anywhere enough leverage (and won't be strong enough).
