Well...I really can't believe this worked. After lots of head scratching and "They can't mean the base is circular while the front will be kidney bean- shaped" incantations on my part, that's exactly what happened to the chin innards I just complete. Worked very well. I'll likely need to tweak a few things shape-wise once it all dries but I'm very impressed. Dang...this thing is well designed. I only added a strip of typing paper or two as these three "tubes" were rolled since I wasn't convinced everything would stay together but it all worked.
Onward and upward!
Phew...Dan
