Easy Domino enhancement for miter joint
« on: August 13, 2018, 04:48 AM »
Hi all !

Yesterday I need to use my Domino a lot on miter joints. And after looking at my Lamello Zeta, I decided to copy an ingenious idea from this machine to have a more accurate usage of my Domino.

I explain it in a video, but in French. Maybe you can just watch only images to understand the simple concept of this enhancement.






I hope it may be useful for you.

Regards.

Nice idea.

In case the screws would be shorten (so they're easier to remove, if the need arises) and countersunk (so the shim would be flat), plus the shim being a thickness that could be easily compensated for in fence height (even mm thickness, possibly one that keeps the fence hight selector in play): Would lead to the domino still be useable for 90° connections without the need to take off the shim.

Maybe we can have one of our English speaking cohorts make an English version of the video so it's easier for people to reference in the future.

It's a very practical method to keep the domino stable for angled joints.

It must be me....

But someone please enlighten me why this is preferred to using the fence at a 45 angle and referencing from the "inside" of the mitre?
This works for me every time without any issues....

From Festool? I doubt it. Most likely from an aftermarket firm like Seneca or Woodpecker. I would buy one.

That’s the nice thing about woodworking... there nearly always is.

But I tend to take the easiest option and genuinly fail to see what the benefits are. I see no need to balance my machine on the wood nor do I see any advantages in accuracy doing so. Instead I only see the disadvantage in having to mount a shim and having one for every angle while the domino fence still is used for referencing.

That’s why I don’t get why you would even consider this?

1) More secure and consistent registration. It just locks in and won't move.
2) When the fence is set at 45 you can't place mortise very close to the internal (135 deg.) edge, which is preferred on thinner stock. Not without a shim anyway.

I could agree with 1 but I never really had an issue with the Domino moving on me when I was cutting (unless I was really sloppy) so I’m not really convinced.

For 2 the option is now using a shim as well :-).

I guess this one isn’t for me...... but it’s a nice idea that others seem to appreciate more than I do.

@CirclDigital it's just easier, quicker and more accurate to make this kind or mortise ;)

In the default way. The domino is not stricly blocked by the geometry. Because the angle is "open".

That's was just a proprosal :p

"Buy one" ? ... it will cost only 5 min to build your own one ;) ?

What thickness is your shim or does the actual thickness not really matter?

Translation?...The single photo says it all.

This is a good option for miters in smaller stock. Thanks Boris!

Ideal shim thickness to be derived from work thickness and fence height range to locate domino near inside of miter to avoid mortising through the outside of work.

@Boris Beaulant I meant to comment on your clever set up of your bandsaw in your video.  That looks like a great machine and is right at hand.  Have you ever considered guards for it?

Yes, but not done at this moment. Not enough time to complete the workshop configuration ;(

I like the idea very much. How do you set the Domino on the alignment marks on the work piece? The cursor is obscured by the miter block.

@Bohdan thank you for this information. I never knew such tools existed and I often watch European language Woodworking videos on YouTube.  This will be a great help. Very cool.

Your angled shim is indeed a clever way of offering support to the DF. But I would use a much thicker beveled shim to give even more support on the back side of the stock. On the "to-try-out" list.

That’s a good question. Since there is no cutout window in his piece he must be registering from the sides of the fence or base or simply using the flip out paddles.

A small notch in the shim will solve the problem. A "deluxe" version could be made of Plexiglas.
BTW. The shim does not have to be beveled at 45. One could use rectangular shim and set the fence at 45 instead of 90.
