Double mortises. For double mor-
tises, align the bit-diameter mark
on the two sliding stops closest to
the centerline with the desired dis-
tance between the two mortises.
In this case the 1/2” thick mortises
are set to be 2” apart.
Use the centering ruler to space the
mortise widths for each side.
This setup is for the 1
½”
mortise
shown above.
Using floating tenons. To use
factory-made floating tenons,
simply measure the thickness and
width of the tenon. They can be
made
super-tight side-to-side or looser
according to your needs.
Align the bit diameter engraved
on the sliding template with the
mortise width on the template
holder.
Tip: Metric bits are available with
inch-size shanks or with metric
shanks, which require a collet
adapter for each metric shank
size.
