I'm not giving up!!!!
Ethan, From the group had an idea sort of like this and I think it's going to work. I used a garage door opener front mount as a mounting bracket and drilled a pin hole through the arm.
This will give me a tight pivot point and since the cap is not part of the arm, I think I can make it work. This is just the start of a long process that hopefully will turn out O.K.
