Using Fence Support on Thin Material

When you’re using tools like a biscuit joiner, Festool Domino or dowel machine, they all have a commonality. They each have a fence that registers the tool on your work. We rely on the fence not only for registration, but also to keep the machine at the correct angle relative to the work. This becomes problematic when the surface you’re referencing the joinery machine on is narrow. And this is a very common scenario. If you’re assembling two pieces in an L shape, one of those cuts will rely on the fence resting on a thin edge.

The fix is in

The good news is that the solution for this is simple, and relies and stuff you probably have plenty of in your shop; scrap wood. Since the material the fence is resting on is too narrow, let’s make it wider. Do this by simply clamping a piece of scrap on to the board, building up with width of the edge. Now the fence on your joinery machine has plenty of surface area to rest on, the joint will be easier to cut and, even more importantly, the slot or dowel hole you cut will be at the perfect angle relative to the face of the board.

    Festool also has a "Support Bracket - 495666" that mounts to the bottom of the base plate. In this scenario, it would be perpendicular to the board pointing downward from the bottom of the base plate. The added support would be from the front or face of the board and not the top, without the need of a block or clamp. It mounts easily with two thumb screws and is part of the Q Set bundle when buying a new DF500.

    I am an inexperienced woodworker. I have used a dowl-it jig but I don't see how I could use it on the non end grain piece like you did in this video with the domino machine. Is there a trick to this that I'm missing or is that type of tool not applicable to this set up. The end grain piece is straight forward. I realize I could biscuit join it, just curious if I could dowel it someway.
