I just bought a DeWalt buscuit joiner to do some corner joints in
drawers.

Never having used one before, I found the process a bit awkward trying
to hold the jointer just right and hold or clamp down the material.

I noticed that there was a hole on either side of the jointer sole
plate. Using them, I fastened the jointer to a piece of plywood which I
fastened to my bench. I then screwed a piece of 1x to the board in front
of and to the side of the jointer to use as a fence. As this fence was
aligned to center the material to the jointer face, I was able to cut
all of the biscuit slots for 3 drawers without center marks. For 3
deeper drawers, I moved the fence and cut them the same way.

Is this a common (or even a proper) way to use a biscuit jointer? I
didn't see any reference to it in the manual and I don't know enough
about other folks' methods of work to have heard of this before.

The big question, is there anything potentially dangerous about using a
biscuit jointer that way?
