Set the bit height so that the tongue or groove (depending on which bit
you're using) is at the desired height (probably centered on your stock).
Cut the profile as you normally would (I'm assuming you're using a router
table, which is the only way I've used a T&G bit set). Then you can use any
good mortising bit of the correct diameter to remove any material remaining
that would interfere with the joint. From the tongued boards it is very
simple, just remove the small lip of wood above and below the tongue. The
grooved boards is more tricky, but using the tongued boards as a guide
should allow you to set the bit height just right (this is how I did it).
It's not the most elegant approach, but it worked.
Now that I have a Unisaw and a very good stacked dado set, that's the way I
make T & G joints now. It is much easier and more straightforward than
using the router set, IMO.
One way I use is to cut the groves for the panels on the rails and styles
first. I do this with the TS. To insure that the groove is perfectly
centered, run each piece 2 times and switch ends when making the second cut.
I then use a wide straight bit in my router table to cut each side of the
stubb tennon in the ends of the rails. Practice on exact thickness scraps
until the stubb tennons fit into the groves. Remember to cut the rails long
enough to begin with to make up for the length of the tennons that will
disappear in the groves.of the styles.
