While cleaning out my desk, I came across some mechanical drawings for PIAA 910 mounts. These were originally designed and drawn by Ken Robitaille ( RIP ), STOC #1962.
Ken shared with me these drawings back in March of 2001. At the time, I had access to a complete machine shop at my former job. For the cost of a case a beer, I convinced one of the machinists to crank out two sets of these mounts. I had one set black powder coated and installed on my ST, the other set is somewhere in my garage.
These mounts hang below the mirror mounts, but use the PIAA mounting stud and nut. With this mount, the mirror housings need cut-away. Using the PIAA mounting stud gives you alignment in every direction.
I'm postings these drawings in hopes that somebody can use them.
