Lee, yes that was the issue. Art based his design off my article in the May June issue that year. My design took an old equatorial telescope mount I wasn't using so I could line one axis with the orbital plane, eliminating the Ned to try to track in both ax and elsewhere. Once set, you only have to swing the mountain along one axis to follow the bird. Art simplified the design (with my blessing) for use on a standard tripod. 

Basically what he did was to fashion a post the screws onto the standard bolt and the have a tee joint th a fits on to the bolt and allows the antenna to rotate around the bolt.

When you set it up. You tilt the pan head so the antenna at it's highest point is at the max elevation of the pass. The prostate the pan head so the max elevation point you just set is lined up with the azimuth of max elevation. IIRC, he made it so you could still rotate the antenna to compensate for polarity. He has a nice picture of it on his QRZ page. 

Feel free to contact me off list if you can't find either issue.

I’m working to build a portable satellite setup. Today I read Keith Baker’s article in The AMSAT Journal (May/June 2017). Keith mentions a mount developed by Art VE3GNF. Does anyone have more details about this mount? My Google search points to the Nov/Dec 2013 AMSAT Journal which I don’t have.
