Accurate indexing of Domino on narrow face and door frames

[DaveInPa]

I’ve got a small door frame with 1” rails and stiles and of I use the 5mm domino and center it perfectly on the rails fits nicely. I have to use the tightest mortise setting on both the rail and stile however otherwise the mortise is too wide.

Besides using a pencil line and lining up the domino is there a way to accurately position the domino for the stile mortise? Basically I want to reference off the rail side and then the same distance reference from the stile end.

Not sure I’m describing clearly but have a feeling this is common thing and there is a trick to it…

Here's one way of creating a hard stop for registering: attach a 17.5mm wide spacer to each paddle. Or butt the spacer against the workpiece and register the paddle against the spacer. Try/practice it on a scrap to be sure it works for you.

Thanks - I can make a 17.5 spacer on my 3D printer. When you say paddle of the domino which part of the domino do you mean?

 

[ChuckM]

The paddles are the black plastic retractable/spring loaded stop latches or edge dogs.

Hi, certainly a situation domino users have often come across. I use a great jig for putting a domino in the joint of architrave around a door between the head and legs called the 'High precision Festool Domino jig' by Carmonius Finsnickeri
As is often the case, I needed it immediately so knocked it up quickly so that I could get on and use it and subsequently didn't fully complete it as in part 2 but it more than served the purpose and was perfectly accurate and more importantly, repeatable. Pics to follow but the youtube video is=RuW_fAFn4xkZVw40
I used a scrap to set the position of the moveable fence from the domino paddles which allowed the same setting to the left and right hand sides.

As long as your pieces are wider than 7/8" (you said they were 1"), the Trim Stop accessory should do the job. I'm pretty sure it came with my Domino when I bought it as I don't remember buying it separately.

I use it in conjunction with Ramon Valdez's Domino Dock. The combination makes quick work of putting Domino mortises in the ends of narrow pieces.

The jig as first developed by Carmonius is now available commercially from Lee Valley Tools as the Veritas Domino Joinery Table

I use it to handle small parts (small mitered frames using 4mm tenons in 8mm stock, e.g., or octagonal frames) and one-of-a-kind curvy or irregular-shaped
projects that demand high precision registration.

The large table surface makes it a bonus compared to the original design.

Thanks - I can make a 17.5 spacer on my 3D printer. Snip.

If you're a seasoned 3D printer user, you might even be able to make and replace the factory paddles (stop latches) with a pair of 24.5mm thick paddles for all your future 1" wide projects! (I'm clueless about 3D printers or CNC machines that some woodworkers employ for their  projects.)

I can use the trim stop for the rails and that’s repeatable. But how do I use it to reference the top of the rail to the top of the stile when I mortise the stile? Can I remove the lower portion of the trim stop?

 

[ChuckM]

I think the trim stop's base is molded as one piece. That's why in all Festool videos, you see it used for the end-grain mortises (rails) and not on the face grain (stiles).
