Oak box is 5'' x7'' ( or there abouts) from glued up scrap. It was all end grain but turned ok. I used a 1/8'' x 7/16 x 7/16 carbide bit , comes from the factory with a #5 hole in it and a cup depression for the tool holder. The box was totally done except for the angle on the recess. I dont know if I will try on the lid or not. The bit mounting and other pics are on my personnal web site.I used the factory edge, there is no chip breaker on these so they shot off the bit willy nilly for sure, also is a still pic of it in action , hard to see but you will get the idea. I just plunged with the corner to start the cut and kept it square to the blank till it was all round then used as a shear scraper to clean up. No tear out was encountered except for the inside where the grain got crazy ... er . If anyone is intrested in carbide , give me a shout.
oh yea, the bit is mounted on a piece of 1/2 mild steel I found in a rusty pile of junk . I inserted it in pipe collet handle and carried on. I used a 4-40 filister machine ss screw to hold to the shank where I ground a flat spot.( lady ordered 7 of em for her family of ... get this .. 7 girls... all married with children, and I thought 4 girls and a boy was tough goin )
