I got the frame built. I knew when I decided to built an English Wheel light enough to easily mount to the wall receiver it would be a challenge. Deflection is not a good thing, so I am hoping to make up for the light frame with some triangulated bracing. Only time will tell if it works or becomes lawn art. I figure if it doesn't work I can always build a steel frame since the top & bottom anvil yokes are bolt ons.
