Restoring Jointer

I recently was given this craftsman jointer that spent a good amount of time in a shed. Still fires up, but I am curious what the best way to clean it up would be. Any recommendations on cleaning or other things I should look out for while getting it back in shape? The feed depth does adjust, the fence moves freely and holds square when locked in. Belt seems to be free of cracks.

Warped wood welcome sign. Will it straighten out?

I’ve had this wooden sign facing the other way for about a year or 2. Just turned it around and now it looks like this. Will it straighten out or should I scrap it?

Waterwheel build

Looking into redoing this waterwheel on my property. This was built by my grandfather 15+ years ago. He used waterever he had and would make all kinds of stuff. The wood on the side is plywood he used to form concrete with throughout the years, the inner ring is sheet metal welded together, oddball shaft and hubs, but has worked and still standing and will spin. (Very unbalanced but will spin) I would like to make the wheel out of wood and then have metal spokes. I took measurements sketched it all out but I'm in a delima about what wood I should use. I located in ohio so cypress isn't much of an option. The next best I seen googleing would be white oak. I have plenty of white oak on the property and could cut some down, sawn up, and possibly kiln dried of thats the route I am directed. I just need help thinking this project over. The overall height of the wheel is 10' tall. My idea was to divide the wheel into 8th. If I would use one solid piece of wood it would have to be 17" wide. Not going to find that in any box stores. I'm open to combining boards together to get my width needed to cut semi circles. Just throw me ideas. In my mind the paddles inside of the curved parts should keep it from warping and twisting but I've never built anything like this too..... the hill behind the waterwheel is another larger pond and we had a valve and trough to feed this waterwheel. I want to do the same but instead of draining the upper pond i would get a pump to circulate and feed the wheel. Any help, insight, advice would be awesome.
