During recanvassing, the old planking at the sheer always poses a problem for me especially when having to pull staples to remove wrinkles. The brittle, old planking edges always seem to break off little pieces especially with staples that have become bent by hitting a tack going in. When these staples are removed they invariably dislodge pieces of planking that falls down between canvas and hull. MY solution to this has been to apply wide cellophane packing tape along the sheer at the top edge of the planking prior to starting the recanvassing process. The ultra sticky tape adheres well to the wood and traps any pieces of planking that might become dislodged stapling and de-stapling, eliminating the risk of undetected lumps under the new canvas.
