After looking at and testing most of the deep hollowing systems on the market, I went with the Clark model. Its many advantages over all of the others will allow you to easily turn pieces you've only dreamed of. In just my third week of using the system I turned a 20 inch end grain, walnut vase that is stunning. Here are just several of the many benefits of the Clark Hollowing System:1. Ease of set up and a relatively short learning curve.2. Incredibly well engineered and built like a tank, including the largest boring bar you can find commercially. 3. Price. I would have gladly paid $900 or more for this system. 4. Communication. Pre and post sale, Keith Clark will always answer your questions and help you get the most out of the tool. The Clark Deep Hollowing System has taken my woodturning to levels I never thought possible. I couldn't recommend it any more highly.
