That's interesting! I have the most recent (Shopsmith-mounted) version of the pin router set up which has the Shopsmith-mounted router arm. Without going to look at it, I think it would be a fairly simply matter to mount the router arm so that when the Shopsmith was raised vertical the router arm would be below the table for under-table routing using the arm as a lift. Remove the tie bar  guard underneath the main table and it might work for under table routing with the Shopsmith shaper/router table insert. Sort of a poor man's Mark 7.
