there should be a vacuum clamp accessory for this purpose.
helper: i used a festool "circular saw" to do something simple and it made it really hard

me: exactly, it makes simple cuts complicated and complicated cuts simple

I decided to use this - https://www.infinitytools.com/2-wide-straight-edge-clamps-3126 I also plan on getting a 100in one for longer boards when I need it but I didn't like how long it takes to clamp a track or whatever so this gives me a straight edge and clamp all in one.  Thanks everyone for the ideas.

When you use these clamps on softer hardwoods, like cherry, you'll find that they leave compression tracks in your workpiece, so put a small piece of 1/4" or 1/2" plywood under the clamp feet before you lock them down.

Do those clamps allow you to adjust the clamping tension? I can't be sure, but i have one of similar clamps and will take a look.

Not sure about the current production of the Pro-Grip clamps but on the original version the cam-like lever had two steps so it had two levels of force, enough and more. Unfortunately the clamp pad was a little loose on the tension rod so even though the clamp was tightened the straight edge could move a little bit laterally.

A straight board held down by plain old clamps is sufficient to solve the problem of guiding the Domino. Add increments to make the board into a story stick and practice holding the machine in place.

Just a heads-up, those clamps can slip. At least the older ones can. Mine are probably 15-20 years old. Actually, that's the reason I purchased a TS 55 and guide rail was because of the slipping. Before the Festool purchase I cut sheet goods with those clamps and a Milwaukee circ saw.

Mine do not have an easily accessible adjustment.

I've done this in the past for a long row of dominos placed in the field of a board.

An FS rail, 3 quick clamps and a 1010 guide stop.



Place the rail in position and clamp, then center the DF 500 on the mark, move the guide stop over and clamp. It's a fast, easy and secure method to prevent the DF 500 from moving as you're holding the tool against the rail and the guide stop.

To increase the grip when working with a small surface (where a rail or straightedge is hard to work with), I have tried two methods:

1) Adhere sandpaper to the fence
2) Spray an anti-slip coating (for stairs, steps, etc.) onto the fence (mask the window before you spray) (https://www.homedepot.ca/product/epoxyshield-epoxyshield-anti-slip-clear-340g/1000785172).

Method 1 would throw you off on the fence depth setting by the thickness of the sandpaper. You can apply the sandpaper when you need to use the intersecting-line technique, and remove it afterwards.

Method 2 is my preferred method as the coating (2 - 3 light coats worked well for me) does not seem to affect any setting. The extra purchase works for regular operation as well, not just for the intersecting-line operation. If you want to remove the coating for any reason, use mineral spirits. Try this on a metal surface if you aren't sure, and follow the instructions on the can.

Since it's made for stairs and such, I assume the coating does not rub off easily and you don't need to reapply it?

The coating has been on the fence for over 4 months now, and the grip is still there. I have not recoated it since.

It is for internal and external use, and the can says it is good on wood, metal and concrete.

Bonus: Use it on clamp handles, and you can't be happier.

Just make sure you follow the instructions on spraying and drying time (kinda picky like the instructions for spraying polyurethane).

The TS anti-kickback stops also work nicely to turn a FS rail into a story stick for the domino.

That looks like great stuff, but doesn't appear to be available in the United States.  Must be some kind of regulations.

Usually it is the other way round that Home Depot Canada does not carry something that its US counterpart does. For example, in Canada, we don't have the dustopper, or this: https://www.homedepot.com/p/Stanley-4-1-4-in-Pocket-Knife-with-Rotating-Blade-10-049/203771308

I suppose Home Depot US also offers the anti-slip spray in a single can, not just in a pack of 6.

By the way, I have not tried it yet, but I plan to spray a light coat of it on my Kapex table to increase grip.

The U.S. version says it's oil based, cleans up with mineral spirits, but says nothing about epoxy.  The Canadian version I'm assuming is epoxy resin.  Rustoleum U.S. makes other epoxy resin products for spraying your garage floor and these say "Epoxyshield."

Interesting observation. The Canadian version also uses mineral spirits for clean up.

When would anyone need to do any of this to put mortises in the middle of a board? Only time I've done it is for partitions and for that I just clamp the partition to the layout line and I'm good to go. What am I missing?

Here is one example of the use of the intersecting lines technique. I relied on the extra grip (from the anti slip) for precision cuts.
