So I'm working on Bazmak's Cirrus V8 2X build. Working on the crank. Hog out a lot of metal on the mill, then over to the lathe for turning. Make the 5 central areas. Now on to the rod journals. With the offset jig, I get 2 journals made. OH, and by the way I'm using a 1/2 inch flat nose carbide bit. I'm working on the 3rd journal and the bit grabs and does this!!!:wall: Maybe I'm hogging out to much at one time??? Bazmak has been helping me and I'm hoping my THIRD crank won't turn out like this one. Take little bits at a time. I've always said, "I've never had a FAILURE in my life. Only learning experiences. I've learned, "Don't do that again!!" I'm heading out for the NAMES Expo up near Detroit today. Hope to learn a lot from some EXPERIENCED machinists.
