Hi guys. I'm planing on building one to shoot up 4x8 plywood. Looks pretty easy to fab up. Found one online i'm going to copy. I'm not sure on what i'm going to use to power it tho. The DIY guy uses a warn pullzall. I don't think i want to use it tho. #1 i don't know how fast it will be. #2 you can only operate it from the ground. I'm thinking more of a winch with a long remote so i can operate it from scaffolding, or if i'm lazy, ride it up to scaffold with load.

Anyone here own or have built one?

There is a limit how high you can go, the cable on the Warn pullzall is only 15 feet long. GO FIGURE.

Yeah, 15 feet is a joke. I need 24 foot +

I'm thinking this... But still unsure of speed.

yeah, these winches are pretty slow. Check this HF one...

If you use a block and tackle system as well as your winch you can multiply the speed and distance with the use of multiple sheaves. Put your load on where you normally pull on the rope to lift and attach the winch to the block where you would normally attach a load. You get a multiple of speed and distance equal to the number of rope falls.

This ^^^^ but you halve the load rating for each multiple. Shouldn't be a problem with a couple of sheets of plywood but it will put a load on the motor, so slow down and let it rest a bit.

I remember seeing one on a home show back in the '90's. I Forget which show, but I remember they used an electric drill and rope to shoot full sheets of plywood up the ladder to the roof. I remember being amazed the electric drill had enough power to pull up a sheet of plywood, and I think it just had a hook on the end of the rope and the plywood slid along the ladder with no guide.

I managed to do something to my shoulder and needed something to lift plywood to sheath the roof. I saw those videos and decided to remove the sping stops and bolt a 2x4 to the bottom of the upper part of the extension ladder and run the HF cable winch through the pulley.

moves the plywood pretty well and took no time to assemble.
