Year by year, some of the chucks and other heavy accessories seem to be more and more difficult to lift and possibly more dangerous to injury both from and to them. I had been thinking of making some sort of lifting device to aid in putting them on and off of the lathe, mill and surface grinder and sometimes lifting a work piece on and off the welding table.
Having seen others install the 'Sky Hook', I decided to make a similar unit. I wanted to make it out of on hand material so as not to incur any costs.
The main upright is a piece of 1x2” DOM which pivots on a 1” solid spindle and the boom is from a 1-1/2x1/8” sqaure tube. The spool housing is just 16- or 18-gauge CR sheet.
The cable spool is just long enough to accommodate the length of cable needed to reach near the floor and there is an anti-overlap plate on it.
The mount plate is drilled to accommodate the T-slots in various machines.
Cutting the ratchet wheel
The crank side of the spool turns in a 1-3/8" hole in side plate. the other side just on a 3/8" bolt.
The ratchet mechanism. Pawl is spring loaded, and thumb released.
The finished device. Found a nice can of baby blue paint to set it off so I won't lose it
So far it seems to work great with just a 1/2" ratchet to turn it but I may make a crank at some time too.
Thanks for looking.
