I recently designed and built this ping pong (table tennis) paddle out of Olive, Mahogany, Walnut, and Cherry wood. It was a fun project to practice joinery and bowties on. In picture #5, there was a void which I filled using reclaimed coffee grounds and super glue (idea from Woodworkers Journal, Issue August 2017, Tricks of the Trade, Coffee Grounds Wood Filler). Thanks for looking! Dale M.
