I have a stash of wood from an old farm house that was built more than 150 years ago, this is some of the siding, not sure but it seems like oak and had many coats of paint. I have been waiting until my planer blades were getting dull before sending this stuff through and it definitely finished them off!
I used splines on the mitered corner construction, and a raised panel bottom. The middle divider/handle is just glued in with dowels on the ends. Finished with linseed oil.
