I am building an uphaul mechanism for a centerboard for an upcoming boat build. They want $750 for a factory one. No way, Jose! It should be easy to build. I am looking for the wide pulley in this picture. The good news is as long as it's between 12" an 18" diameter, it will work. Purchase will change, but it will work. So far I have found a Harley Davidson belt drive pulley that may work, but I would have to add sides to it. It only needs to hold about 10 feet of 1/2" rope. It needs to be bronze, stainless, or aluminum. It's not going to take much strain- the board will come in at around 180 pounds. Rather than wire on the small pulley, I will probably use nylon strap. I am also looking for an appropriate pulley for that, although it will work to just mount it to the shaft if the larger pulley has a large diameter shaft. Again, purchase will change based on the size of pulleys, but I've got a very wide range to work with. As long as I can pull it, I'm ok.
The one pictured was custom made for a boat for someone with much deeper pockets than I. I've been looking at places like Granger, McMaster Carr, etc. I was hoping someone here sees this picture and says, "Hey, that looks just like the pulley off a _____."
