Have you checked with Barry Baxter? He seems to have EVERYTHING!
BTW, I enjoyed chatting with you at VSC. See you next year?
Oh, and the problem I had with my Baby Clown was definitely the compression screw not staying put, even after lightening it up and adding a spring. I will try it again Saturday with blue Locktite gumming it up. If that doesn't work, I got a locking bar from Eric Clutton.
