I made some updates and tweaks to my mirror design last night (yes, I often design things during my free time for fun). As it turns out (not surprisingly) my 'ball and cup' pivot didn’t quite work. The ball wasn't gripped by the cup with enough force to prevent it from rotating and eventually the force of the bolt that squeezed everything together caused the part to fail. Can't be having that happen!
As a result I've taken what I learned from the ball and cup design and created a completely new design. Its much more robust and allows adjustment in two axis plus rotation. Once the desired rotation is dialed into the mirror it can be fixed by a set screw.
Other additions and tweaks include enlarging holes for #10 hardware (since I originally designed for .125" hardware but I dont have any readily available and on second thought that’s kind of small) as well as added some logo branding to the lower left hand part of the mirror. I don't recall if I had curved the edges of the mirror in the last post (or mentioned doing so) but the mirror body is now curved to match the curvature of the glass. I should be getting an actual mirror delivered today so I can put more accurate numbers to the glass model I have in solidworks and print a Rev B which can actually be assembled and tested.
