A friend's brother made a sign for their camp out of a disc cut piece of wood. Traced out what they wanted then roughly "carved" it out with a dremel tool. Then burned the cut portion with a soldering iron. Coated with spar urethane. It has held up well outside for the past couple years. It is on the outside of their camp under a covered porch.
I do some wood working on the side and if you had an idea of what you are looking for I'd be happy to see if it is something I would make. If interested PM me.
