Yeah, unless you have some large panels/sides, a 0.375 ballnose doesn't leave you with a lot of variation choices. It did allow me to play around with it a bit and see that the finger length columns start on the right and zig-zag back and forth for order. I was trying to get the large middle finger to be shorter, but could only get half of it to do so, giving me the stepped finger, but with the jagged intersection, so I just went with it full length. Settings I used are attached. It fit pretty tight, so I could have allowed more for glue gap. The attempted negative overcut was -0.197.
G,
Yeah, I found that the finger length part of the cut is one thing affected by that and had to do a little chisel work to clean up the radius left on the end of the fingers. What do you think about doing a small zig-zag or smooth ramp for the start of the end cuts instead of three full depth plunges? It might be better for keeping the tool a bit cooler. Although this was more pronounced in my case as I was using 0.8125" material along with 0.375"+ more due to overcut. Just made it a bit more interesting as it drove the 4 flute 0.375" bit all the way down in one 90ipm shot! PM sent.
