Control over the router.
The mechanical advan-
tage ratio is about 2.5:1 at the handle, so you’ll have
perfect control, even though you are climb-cutting
all the way.
Check the fit.
The tenon could be just a bit fat at this
point.
Adjustments are amazingly easy.
The templates
have a slightly tapered outer edge, so moving the
guide bearing outward (down the taper) slightly
adjusts the fit by a few thousandths of an inch. Once
you dial in the fit, you can crank out piles of cleanly
cut, deadly-accurate tenons in minutes.
Once you’ve identified the best fit for your bit and
guide bearing, note the position of the guide bearing
relative to the three index marks so you can quickly
repeat that size M&T the next time you need it for
your work.
For wide workpieces, combine templates.
Use a
square and the scale on top of the template hold-
er to align the templates. Make sure to leave room
between them for the guide bearing to pass through
(remember the 2-to-1 scale again as you select your
guide bearing and space the templates).
Multiple tenons are just as easy.
