The instruction was to cut two patterns in order to glue and clamp the laminated rockers; one was for the inside curve that is a 42 inch radius and the other was the outside radius of the form. It would be the 43 1/4 inch radius form. I did cut the patterns, but then I questioned the need since I was going to cut three 3/4 inch plywood pieces for each pattern.
So instead of working from the pattern to cut the 3/4 inch three layers I decided to use my router circle jig and cut the three inside curve of the forms. Then I would also cut the outer curve of 43 1/4 inches using the same JIG but moving the pivot point.
This photo shows the three layers of the two forms; the inside and the outside forms. Tomorrow I will glue the three layers together. Later or afterwards I will rip the 1/8 inch thick strips at my table saw. I will but over sixteen of them in case any of them break in use. With an 1/8 inch piece of masonite and smothered in paste was, I will be ready to glue eight of the slats into one router between these forms and held in place with strong clamps.
The three layers on the left in the photo below is the outer stack with a curve cut to 43 1/4 inches in radius. The stack of three plywood curves in the inner curve cut to 42 inch radius. The rocker will be laminated with eight 1/8 inch thick strips with masonite glue cauls between the clamping form and the rockers.
