Hi all. I am currently building some stress-skin platforms for my theatre and I was wondering about different construction techniques people might use. The technique we use is based mainly on what materials are avalable and don't cost a fortune. We rip 2x6 into 1 1/2"X 1 1/2" true for the frame. We then skin both sides with 1/2" CDX 4-layer ply. I'm wondering if anyone else has modified the orriginal Yale design for thier own needs and what matterials they used. I'm collecting this information for reference and latter use. Thanks.
