Hi Bill, I can't remember how long ago this shape was shown to me, and I have passed it on over the years, with very good feedback from the users. With me having a fairly powerful mill, I can easily take a 0.100" cut with it on non ferrous, half that for mild steel, and end up with an accurate and reasonable finish. Put a 5 or 10 thou cut on and it comes out like a mirror. The cut to the left is the rough cut, on the right, the finishing. This is on ali bronze. It is ground up to a full quarter rad as on a left hand lathe tool, with lots of top and back rake (say 10 to 15 degs). The tool is resharpened by running a dressing stone (I use Arkansas) over the face you can see in the pic. It needs to be razor sharp. Hope this helps. John This is a shot from Darren's lathe project, and was done to show the shape of tooling I use and the surface finishes that are produced. So if you see machining shots of mine, look at the type of tooling I am using, it just might give you a clue, otherwise just ask. |
