Articulating Dowels

[4nthony]

I came across this article this morning. Interesting idea for incorporating mitered corners and other angles into knock-down furniture.

That's cool.  But the offset for the locking piece isn't going to be consistent from angle to angle- Dimension X, in this pic:
I wonder if they have a good way to jig that up?

Anyone know what machine is used or available to mill those holes? As a friend of mine said, placement of holes for the locking pins seems critical.

One idea-  the dimension "A" on the right side of the image is fixed, or so it would seem.  If so, a simple edge jig like this would work, if you cut the white piece down so it hangs down exactly "A" mm from the face.  The contact point would then land on the bevel at the exact right point for the offset to be consistent, regardless of the angle.

The drilling kit is pretty affordable.

That was my thought, too.

If you convert the jig's product page to English, it says "Caution : Cannot be used for miter joints."

Maybe there's no jig for the articulating dowels? Or, you have to cut the miter after drilling the holes?

X-drilling distance will always be the same if it is measured from the centerline of the dowel (the light grey line on the mitered edge). If a practical means of making and marking that measurement is found then the drilling location can be readily found no mater what the miter angle is.

Yes, that's the problem I identified.  See my 2nd post for that exact solution.

For production work, there's a drill press similar to the Blum/Grass etc boring machines. It has a vertical and horizontal drill, so you can drill both holes.

Your suggestion would work for sure. Sorry, I scanned over it being distracted by the photo.

A have seen a couple other knock down systems that use a cone point set screw as the tensioning method.  I did not think it was a very forceful connection method. So I have never tried them.  (I have used cam-lock types)

Anybody used such a system and give an opinion ?

The entire DF500 Domino Connector set is based on a cone point set screw.
