I am building a corner cupboard with solid wood vertical strips about 3" wide for the back. The back is curved with a radius of about 16" and needs to fit flush to the rear of the curved display shelves. Thus the boards need to have a uniform concave profile over there 4' length. What is the best way to do this? The obvious way would be a molding machine (too expensive) or making a cove on the table saw but the radius would be too small. Is a round spokeshave the way to go? The only problem I see with this is it may be hard to keep it uniform (at least for a power tool kind of guy).
Any thoughts?
Thanks
Bruce
