Steve, I have Keith Clark's deep hollowing setup. His web site is theokspindoctor.com. I have the 1 1/4" bar and the 1 3/4" bar but mostly use the 1 1/4" bar. I also have his steady rest. The builk of my hollowing is done with a cupped carbide cutter and then I do final cleanup and deep bottom work with a shielded cupped cutter head from my Roli Munro bar mounted on the 1 1/4" bar. There are some other pieces and mods that come into play I can share in more detail if you like.
