Parametric Table

Looks awesome!
What material are the side rail “riding plates” (and their supports) cut from? I had suggested cutting them from dimensional lumber such as 1" x ?" x 10" but you had said not to use lumber.

How many sheets of plywood would this take without the shelf? Just the torsion box and side rail “riding plates”? I ask for comparison to the one I had been working on.

Oh, wait, is this not for a full sheet plus (ie. can address all of a 49x97 sheet)? I am looking at the dimensions and it seems it is not. EDIT: Sorry, it is for full size!

OK, so I guess my first question above, but related to my table, comes back into play. I had put forth an idea of doing the torsion box from plywood, but using 1"x ? x ? to get the side rail riding plates, and you had mentioned not to use lumber. MDF longer than 8’ is made, but I don’t think it’s very easy to source for many of us. Can I get you to revisit the topic, either to explain why we should not use lumber for those side rail riding plates, and/or explain what we should do instead? These would need to be about 114" long.
