      Excellent video. One additional tip that I learned from experience Experience : (what you get when you do not get what you want) Using the same Porter Cable biscuit joiner as in the video, it’s important to take the following steps when making each cut. 1) Position and hold the biscuit joiner solidly against the edge or cleat. 2) Pull trigger and LET THE BLADE GET UP TO FULL SPEED. 3) Then plunge the cut.

      I learned the hard way that if you just start plunging and then push the blade in, it will have a tendency to shift the cut and/or move the board.

    So, I get it that the tool places the blade 3/8″ upward from plate edge which places the biscuit in the center of 3/4″ plywood, but what if the shelf material was 1″ or 1/2″ plywood? How would you get buiscuit in the center of the shelf piece? I also have a similar looking Porter Cable joiner. Thanks!

      Hello DR. For the 1″ material, I would still set the biscuit joiner on its base and not worry about centering the biscuit. It will still give you the same alignment benefit whether or not it is centered. For the 1/2″ material, I would either prop the plywood on a spacer to bring it to a better height to locate the biscuit, or I would use the fence. You can always use the fence if you prefer, I just find it to be quicker and easier to use the base of the biscuit joiner as a reference.

      Hi William. The depth of cut can be varied depending on the size of biscuit that is used. The slot is generally about 1/16″ deeper than half of the width of the biscuit. That provides just a bit of wiggle room so that you have some adjustment and it also allows for some variability in biscuit sizing.
