Nice, Alvin. I appreciate you checking that out. I purchased some nice tight grained red oak 1 x 4, which I ripped it to 3 inches wide and then planed it to 5/8 inch. Seemed too thick, so I then planed it down to just a smidge less than 1/2 inch. Then put the 1/8 inch radius roundover bit in the router to ease the edge. Think I'll leave it at 3 inches at this point. Will try to get one or both of the pieces fitted tomorrow (or soon thereafter).
