Chris, I assume you are talking about the mcNaughton bowl saver and not their hollowing system. My advice is don't try to do everything at once. Turn bowls and small hollow forms you can handle with your 1/2" Jordan tools. Develop your markets and skills. You can sell a whole lot of 7" tall hollow forms if they have nice curves. Then look at tools for deeper hollowing. I have a set of Carbide tools for hollowing that I never use because they are too slow. I use HSS cutters. The Bosch tools will fit any 3/4" socket. What Handle do you have for the Jordon tools? I think the Jordan Armbrace comes with a 3/4" socket and an adapter for the the 1/2" tools. If you are happy with that handle it may already fit a 3/4" tools. The Jamieson handle will fit the Bosch tools. You can build a back rest withe screws, a few feet of 2x6, and part of a 1/4 sheet of plywood. The backrest can be down right flimsy and work well.
