These marine plywood ½ ones will replace the PO ¼ in ones. Heavier yes but smaller in size so it should even out. Also stronger as one of the older boards has broken. Also we are hoping these may be easier to store as they are smaller in width.
Brought the goods out from my secret hiding place at work.
Had to reshape the old boards so we could use them as templates.
That done it5 was time to cut out the new boards.
OK forgot the drill and want the slots to be accurate so we can not finish the rough cut today.
Could have used the circular saw to get started on the slots but I am not that skilled at this and could easily hack up the slots so it can wait.
