Finished the proto-type today.
Here's some pic's of it finished, one added feature to these arms is that they are interchangeable from left to right. I made it so that the arm is adjustable vs being welded to the base, so you have the added option of adjusting it up and down as well as flipping it for left or right.
Here is the arm only.
Here is the arm with a 5.5" x 7.5" head.
Next post has more pics.
