Curt do you have all the pieces cut and ready to go. I have access to pretty much any type of welder and some limited experience doing it. I have wanted to build a winch myself just never got around to it. If you have the know how and I have the tools, could we get together and make two of them. PM me if you want to try, we can fit some wakeboarding in too if you come down.
There is no flat plate on the back, it is all open guides, the supports just angle backwards. There are only 4 parts that are flat metal. The floor, the face, and the two pieces on the side... There is going to be a splash guard between the engine and the spool.
