I have an ancient chain hoist which wasn't holding the hook. As fast as I cranked it up, the hook would slip back down once I let go of the chain. I tore it down and found that the friction clutch disc had worn to the point where it hardly bore.
This is an awesome old chain hoist which Ernie gave me. I really want to make it work correctly again. Has anyone else solved the problem of where to get a custom one-off replacement friction disc?
For an explanation of how the friction clutch works in a chain hoist, see:
mount an X-acto knife in a boring tool on center height, parallel to lathe axis put a lathe center in the lathe spindle move the cross-slide until the knife point is on the lathe axis i.e. pointing exactly at the lathe center zero the cross-slide dial & remove lathe center put the faceplate on the lathe spindle cut a disk of plywood the size of the faceplate cut a disk of the friction material the size of the plywood (or smaller) punch identical bolt circles in the material and the plywood bolt through to the faceplate, so its faceplate|plywood|friction material crank the X-acto knife out the radius of the inner hole start the lathe and feed the knife in, cutting out the ID crank the X-acto knife out to the radius of the disc OD cut out the disc
But I don't want to buy a whole sheet!
Anybody been through this?
