I am designing a headboard that will incorporate 7 or 8 panels, each panel about 8″ – 9″ wide and arched at the top to match the tightly arched grain in the resawn walnut veneer. The radius is 4″ but will not be a full 180 degree semicircle, probably about 130 to 140 degress. I want to frame the panels and put a decorative edge on the inside and outside edge of the frame as well as cutting the slot to nest the panels. The frame arches will be steam bent pieces and then stack lamininated. The frame dimensions are not settled depending on what I learn from responses to this post. The series of arch frames will be jointed after shaping. The question is the best method to shape the pieces since the radius is fairy tight and the stock is narrow and always real close to the cutter head. The material is walnut. Thank you for any suggestions. Doug
