I have a Kobra Deep Hollowing Rig For sale. This hollowing system was designed and manufactured by Al Crandall and Jerry Arnold of Lapel, IN. Set up for 20" swing General 260. If you have a different model but same swing, the only part you "may" have to tweak is the center gap filler on the bed ways.
You must come to Indianapolis, IN to pick it up. It is far to heavy for me to ship. Asking $500.
