Torsional Rigidity

[v7guy]

when building something like this you need to take in to account alot more than just the hieght of the material. The width is going to be just as important both from the standpoint of ergonomics and strength. Thought I would bring it up in case it wasn't just a typo in your last post.

If you haven't I would consider doing some reading. There are some really good books out there.
