Topic tags/keywords: domino jointer biscuit joiner

I am using a good friend’s Domino jointer and have some questions. The hairline does not line up exactly with the center of the bit. I know you can adjust the plastic window but I’m wondering if this is common to have to adjust these upon purchase?

One more thing, is the width of the hole supposed to be set to the exact size of the domino or do you always use the next larger size?

I would prefer using the setting to get a tight fitting domino in both width and height. Anyone got any experience with the Domino jointer?

Usually Festool is very good at setting up their tools before packaging, but I’m sure once in a while they miss adjustments—being human and all

For those that don’t know, you must adjust the width of the domino when it’s running to avoid messing up the machine.

When doing several dominos it’s wise to use the wider settings as it’s easier to align the joining pieces. You can have one tight fit and let the other ones be wider and it will be less of hassle to put together and just as strong.

Please contact our service department at 800-554-8741, M-F from 8a-5p ET. They can assist with any issues you’re having with your Domino, including the alignment of the cursor window.

The tenons should be a fairly tight fit in the most narrow mortise setting. Depending on humidity and other factors, it may fit so tight that you need pliers to remove it when dry fitting.

If I can be of any assistance, feel free to contact me at

I don’t use the wider mortise settings unless I’m just using the dominos for vertical alignment. Normally I’ll use a block plane or a sanding block to remove the ridges on the sides of the dominos before inserting them into the mortise. That allows just enough room to offset potential problems with misalignment.

As far as adjusting the plastic plate goes, I have no idea if it’s common or not. I adjusted the one I use and that is it. I don’t remember if it needed adjusting but I’m used to tweaking the settings of new tools so I tend to do it out of habit even when I get a high quality tool.

Thank you all for your feedback. I’ve adjusted the hairline cursor with almost 100% success. I had to slide it all the way to the left but it seemed to work well. The little it is off now could be to my own fault. My particular application only needed one per joint so I used the tight fitting size.

Shane, thanks for the info. That’s great customer service. I’ll contact you off list with further questions.
