Thanks to all who enlightened me so on the device and how it is used! I learn something new every day on this list, much more so than in real life! I had no idea the portacatena was so complex, or rather the set-up is, being so involved. I now know it is not something I just bolt on and go! Buying the parts soon enough, and it is a cool project. Thanks again to all. Hopefully I can make Cirque next year, have been kicking the idea around with Jeremy Haynes, and plan on bringing the Mercian Pro if it works out!
