I've just added a Kerf Spacing Calculator to blocklayer.com, that some of you may find useful. It works out the geometric spacing of the cuts so when bent, the inside edges of the cuts join to create the curve. The depth of the cuts (and remaining wood thickness for the bend) can't be calculated (that I can work out anyway). That seems to be the art of it. Depends on the wood and the dimensions. Trial and error? But this will produce simple geometric diagrams, so you can see the wood and cuts both straight and bent, and drag sliders to animate angle, radius, cut width etc to see what cha
Just ran across this video, I'm going to have to try it. The other technique I've seen is to make two L-shaped jigs, Put one on each side of a board to be dadoed. Put your piece to fit in the dado between them and slide them together and clamp in place. Then with a router with a top bearing, zero clearance bit less than but at least half the size of the dado, run across one side and back the other.
