Hi Bill, That was just for the photo. I got the arm yesterday and plan to design and have machined a custom outboard arm pod on which to mount the arm. It will fit, but the calculations are a bit complicated. I'll figure it out and then have someone make the apparatus. It should be a fun little project. I think patience will be required. I am very impressed with the build quality of the arm. My sample is in excellent condition and I have been cleaning it and getting to understand how it works. I am not quite on speed dial with David K, but he has offered his help, and I appreciate it.
