For an upcoming project, I need perfectly flat, perfectly straight stock. But I only need 1/2″ thickness out of 3/4″ boards. So I’m taking the laziest possible approach: skip planing. But because the boards start off too thin for true skip-planing, I am pulling a page from the planing sled handbook and using blue tape to fill the hollows.
Each outside edge is planed perfectly straight and without twist, and the blue tape will ensure the board rides to the planer table evenly and without pressing flat. Thereby, one side of the board will be made perfectly flat. With the tape then be removed, the board can be flipped end over end and sent back through the planer for perfectly parallel faces.
Speaking of parallel faces, I apparently left my winding sticks at my parents house, hanging off my old workbench. I needed some for the above skip-planing. So I made some out of scrap 3/4″.
At 1.5″ x 15″, I’m sure they will get re-purposed for actual furniture.
