So here are the pics I took as I put it together.
Decided to use 1/4" luan ply for gussets and a way to joint the riser to the end pieces. Glue only.
While building this I had to keep in mind the portability of it. So making a way to nest these parts was also a consideration.
A little ingenuity for a quick connect is the use of a cheap shelving bracket cut to fit.
A single 4' section works good, but we want to be able to add section to it. In this version we have three risers that attach by the two hanger rods and the stabilizer middle section.
