If you use small pieces of plywood, you will need to glue them together withscarf joints to retain the strength required. I did this in my floorboard.As I recall, I used an 8:1 scarf, so for =BC=94 ply, the scarf was 2=94 wide.Jack PhillipsNX899JP _____

Nope. Very little strength in a butt joint. When you make the scarf, makethe piece wider than you need so you have a test sample to break. Theplywood should tear before the glue joint breaks. With a butt joint, theglue will break every time.Jack _____
