This afternoon I made and fitted the roller / spool thingy that the lifting webbing runs on at the end of the outer arm.

I cheated actually as when looking for suitable round stock I found something I'd chopped off some mechanism some time in the past that already had a spool shape in it! I just had to turn it to length and sleeve it down to 10 mm !

Bits needed chopping off the box section to mount the spool and then it was just a case of drilling the remaining vertical cheeks and putting a bolt in (yet to find one of proper length.

Then re-assembling the winch onto the arm and fitting the webbing it was ready to test. Finding a 56 lb weight I hooked it on and wound it up and down about 2 foot.

Cranking the handle there was an alarming graunching noise in a couple of places, and examining the gear on the handle shaft there is already visible wear and it looks horribly as though it's made from aluminium alloy - surely not :scratch:

OK gears have to wear together in but heck this is lightly loaded and has only turned a few dozen turns - it can't be right :scratch:

56 lbs is about 25 kg and this winch is rated at 170 kgs :bugeye:

Sea.dog:
That's not looking too promising.

I think i have 24v wheel chair motor/gearbox in the shed!

Muzzerboy:
Looks as if you may doing some unintentional self-hobbing there. :bugeye:

awemawson:
It can't be a perfect mesh anyway as it seems to be a straight cut involute gear mounted at a slight angle and meshed with a worm gear.

Maybe the two will wear in in time to a happy relationship having knocked the high spots off each other !

I'll add another 56 lb weight tomorrow, which will bring it up to my expected full load, and wind it up and down a few times, but I will re-grease the gears first.
