Question about Plywood thickness

The additional parts rules state that we may either use 1/2" thick or 1/4" plywood for the robot.

Logically… I “could” glue together a piece of 1/2’’ and 1/4’’ to make a 3/4’’ board.

This “glued” 3/4’’ board would be the same as a purchased 3/4’’ board wouldn’t it? So working from that…is there anything stopping me from using a 3/4’’ board?

If the additional hardware list says only 1/2" or 1/4" plywood, they mean it. Using purchased 3/4" plywood is illegal. Glue the 1/4" to the 1/2" and be done with it.

Good Luck,

P.J.

Would laminate be considered a fastener?

Would laminate be considered a fastener?

I’m not sure what you mean by that, but as has been stated many times, adhesives are considered fasteners and are therefore on the AHL in unlimited quantity.

The adhesive used to make a laminate is certainly a fastener. But the substrates, the things you are laminating, must be legal materials to start with.

SO to answer the original question. No you cannot use purchased 3/4" ply. However you may purchase 1/2" and 1/4" ply and bond them together with the adhesive of your choice to make 3/4" ply.

Though why you would want to is beyond me. 1/2" ply has always been good enough for us.

At the risk of being redundant I’m posting this answer. As stated you are allowed to use the 2 pieces of plywood and glue them together. My former team did this and we used liquid nails as our adhesive. It worked well for us and at tech inspection we got strange looks because no one had thought of doing that. Oh well, the addition proved to hold up well, better than simply using the 1/2" we prototyped with…
