When you decide to use plywood, do you do any calculations to guide your design? Do you use any of the formulas that civil engineers use for plywood (such as
http://www.canply.org/pdf/main/plywood_designfund.pdf), do you use rules of thumb you can share, or do you just iterate until it works?
Are the captured nuts the only way you fasten the sheets, or do you glue them as well? Do you find the structure fails at the fastener typically, or some other way?
Thanks again for sharing
