Real Life

This frame design was based on analysis of stress concentration and material cost, and proved to be extremely rigid in the end.

Relatively simple step of screwing the ply boards into the wall frame.

This was the most difficult part of the assembly. We first attached the 8 ft long steel hinge to the base, but then had to accurately drill holes in both one flange of the hinge and the corresponding attachment face of the wall. These holes had to line up perfectly, and then to actually bolt them into place we had to have a team of friends making adjustments to the wall orientation using 4 car jacks to support the weight of the wall. 

After getting the hinge attached properly, and winch set up to lift the wall, I was able to attach the support legs and drill pin holes for them at specific angles so that if I wanted to change from 40deg to 50deg relative wall angle, I just had to line up the legs with different holes. Something identified in FEA was high stress concentration on the outside of the support arms, and a tendency for them to bow outwards in the presence of high loading. To solve this we attached 2x4 studs (seen in this image as the lighter colored wood on the outsides of the arms) to the arms which has been proven to be a great solution. 

This couldn't have been done without the help of Andrew, Kenton, and my Dad, thanks guys!!
