So far we have only illustrated joints where the mortise and
tenon workpieces are the same thickness. There will be numer-
ous times when this is not the case, as in where the tenon piece
is thinner and centered on the mortise board
➀
, and where the
tenon piece is deliberately off-center on the mortise piece
➁
.

Single or double (in-line) mortise and tenons are straight
forward. Simply mount and sight and rout all the tenons as shown
before
➀
, then mount and re-sight the mortises at the desired
front-back position before routing

Take great care to not “trap” the bit against the side of tenon
rails
➀
.
Do not attempt to rout center tenons in rails thicker than

/

"[34mm] before referring to 5-39 through 5-44.
Without using the table movement as prescribed, the bit would
have to be plunged into the side of the tenon rail causing the bit
to powerfully “drive” the router across the jig. This could be
dangerous and can damage the jig.
Before using your Leigh FMT Pro you must
have completed all of the preparatory
steps including reading the router safety
recommendations on the previous pages.
If you haven’t done so, it is essential that
you do it now.
