The December 2019 Fine Woodworking magazine contains an article on how to make a Japanese kanawa scarf joint. Since my skills in CAD are much greater than those with a chisel, I decided to try to make the joint using VCarve. Here are the results. I used a 1/8" end mill to cut and promptly realized that the tool deflection is significant for this application. The glued together joint required a bit of sanding to make it fit, but the end result showed that the joint can be made on the CNC.
Good judgement comes from experience.
