Very nice work steve! I remember this from the garden site but I don't think it was finished. Did you cut these gears?

I bought all the gears but the two smaller pinions are cut from 12'' pcs of gear stock so I can make them the way I want. I think I've mentioned in the past but I think there's around $100+ buying the worm & the other gears. I even put a tiny thrust bearing on the end of the worm. Right now I'm working on the mount for the motor I'm going to try. After testing it and getting a RPM of the winch drum, I running about 30ipm and that should take only 6-7 minutes to boom up or down.

Stuff:
The pictures were resized too big by accident.

I got some more done with the boom hoist and some on the base of the boom where it attaches to the revolving frame.
