In over twenty years of turning hollow forms I have been able to try every system that is out there, and a bunch of homemade rig's of every setup possible. I found Keith's setup online and after a bit of reading and thinking about his setup I knew I found the golden ticket. Seriously, this is the best thing for hollowing on the market. From small diameter to the largest and longest piece your lathe can hold, this thing works. And beautifully. If there is a better setup out there I would have to see it to believe it. And even then, my unit is not for sale. Awsome, doesn't fully explain Keith's setup!! Thanks, Gregg.
