in the guard recess to prevent accidental
routing of adjacent tenons.

If the tenon rail is thicker than 1
5
⁄
16
"[34mm] (as is
most likely with this type), then great care must be exercised not
to “trap” the bit
➀
when routing the third tenon.
i.e. The bit would have to be plunged into the side of the tenon
board. This could result in the bit “driving” itself across the board
which could be dangerous.

against the stops
➀
as if to rout a quadruple tenon. Then add a
small “guard” piece
➁
to the L-shaped guard in the guide recess.
Now rout away part of the workpiece
