I once labeled this a universal jig because something similar to this was marketed by that name by Sears for many years, although this is not a Sears (my father had one, so I know the difference). A couple of lucky hits on ebay finally led me to this Shopsmith Tenon Master (#555479).
Norm only used this a few times. The Shopsmith series didn't last past the first season with a couple of minor exceptions, this being one of them.
Appearances: Episodes 403, 408, 409, 505
