I am making several cherry chairs and need to clean up the curved back and crest rails. I want to use a bearing guided router bit but the crest rail is 3 inches wide and the largest (longest) bit I have or can get is 2 inches. I was thinking about using a bottom bearing bit along with a masonite template to shape the lower half to two thirds height of the rails and then replace the bit with a top bearing style and use the freshly routed face as its guide to clean up the remainder of the face. It makes sense to me and I will try a few test pieces but I wanted to run the idea by you all to see what you think about it.
Instead of using a router I could sand and/or scrape the surface for final shaping but I would prefer to get the more uniform surface obtained with the router.
Thanks in advance for your comments.
