When I was building the house I had decided to hang all the sheetrock myself and sub-out the taping and texture because that would be just too big of a job to take on by myself.
The house has ten foot ceilings and the time before I had rented a sheet rock hoist it wasn't until I got home and realized it was meant for eight foot ceilings and I had to make piles of pallets with a sheet of plywood on top to reach the front garage ceiling and I tend to drag projects out forever so I try and avoid renting things if I can buy it or make it for the estimated cost of a rental. I've always loved to weld things since I was a teenager so I made a trip to the local salvage yard and got some scrap pipe and tube steel which ended up being about $40 since you pay by the pound. I then went and bought a cable hoist like would be on a boat trailer to put the thing in and out at the dock and 4 heavy casters and pulley with a bracket included for about $50.
Step 1: The Lifting Jack
The basic working component is a two inch pipe about five feet long and a piece of square tube steel, thick walled and I think is about an inch and a half across that fit loosely inside the two inch pipe but not so loose it would just float free since you want it to stay inline as you extend it. By dumb luck the pulley I chose had a bracket spaced wide enough for the square tube to fit through but snug enough to keep the tube aligned so it couldn't spin and get the cable wrapped up and it held the pulley pretty close but not touching the tube.
I never question dumb luck!
