Author Topic: Domino DF 500 Q - How to cut domino on 30 degree included angle piece  (Read 1001 times)

Good Day:

I am making my wife a shelving unit to hold her doTerra oils and I have a few questions on using the Domino to reinforce the joints on the triangular assemblies.

For the the 30 Degree included angles is there an effective way to get a positive registration setup while cutting the dominos (at the top of the triangles)?

Is there an easy way to layout for the dominos at the base of the triangles?

Thanks for your help,

Michael

I'd install the Dominos parallel to the edges as it is laying in your photo. Install the support on the Domino and use the retractable stops referencing the long point.

One good option to do it. The fence height is quite accurate (so no problems expected here) and in case you mess up the alignment against the long point slightly on one you can easily sand down the side of a domino (to make it a bit smaller) for that one mortice. As the stock looks thick enough you could even more of them (2+, one front, one back), but you should reference them from the same side.
I would suggest to clamp more of them behind the one you're processing, to prevent the fence from tilting.

The other way is to reference as intended (by festool) on the miters:

I’ve not had good luck with doing Dominos on angled joints. I’ ve resorted to splines with excellent luck.

I had issues with miters at the start of using my domino too.

Solved them by clamping the workpieces with the face of the miter toward me (and pointing up, for smaller pieces I add same thickness scraps to the side so the fence is fully supported tilt-free over the full width) and having the fence (the part you set to the angle and height) against the top (directly upwards pointing) side of the stock - the weight of the machine itself (with the heavy motor pointing at some angle toward you) holds it nicely in place and perfectly registered, by just holding down the fence handle (with a sligh push forward to keep it registered and from moving sideways).

What I found is that it's good idea to only hold the machine at the fence (after alignment is complete) and doing the mortice by pushing the back of the machine. Since I only use the back handle for initial positioning and never while actually doing the plunge: no problems anymore.

This with a 700XL, no clue how good that works with a 500 as I have none.

Exposed Dominos in mitered corners.

This looks like a project that really could test a person’s patience and geometric layout talents.

Personally, I would rely more on glue and screws/nails over the domino.

Where's the fun in that?

It is glued.

Once set up, nothing to it.

I highly doubt that there is “nothing to it”.  As simple a design as this appears to be, the layout of the tenons has to be spot on even if using the loose settings.

And by the way, thanks for telling me that glue is used with dominos.  Now I know what I’ve been doing wrong all this time.

You guys kidding me?

Dominoes, glue, screws?

BRADS!

Just kidding. As a challenge, I would definitely try dominoes.

Cutting the angles on all the pieces accurately could be as much a challenge as, if not more, mortising them here.
