I took the advice I got from Captain Sckully seriously. I have built a new base from acrylic and then from the topside drilled holes so I could fasten the guide rails in place on the base with screws. This will be a safer solution and it will be repeatable.
I have also completed the construction of the clamping forms in which I will glue and clamp the rockers for this chair. This bent lamination is based on the 42 inch inner radius and the 43 1/4 inch outer radius specified in the plans.
In addition I have built the routing jig that I will use with my router to get the under-side of the arm rest completely smooth to fit the eight foot radius.
