Dominoes and glue squeeze out

[Jason Kehl]

Thanks Rick.

I will try gluing as I have been, and dealing with the excess as you suggest.  The end goal was/is to quickly obtain a strong joint (maximizing the usefullness of the Dominoe) that is ready for finish, with no surprises. It seems as though my initial goal of avoiding squeeze out may not have been as good an approach as simply finding a better way of dealing with it when it happens.

Marc;

The Domino is an excellent tool, I would not want to do without it after getting used to the speed, accuracy and convenience of it. It was my first Festool and it has been a very slippery slope ever since. You still need to clamp the joint to have everything pulled tightly until the glue sets up.

Marc,
The Domino fit is very tight, and yeah you could probably get by without clamping, but I always clamp.  By the time I get to glue up, I have put a lot of effort into a piece and its just not worth the risk to do without clamps.

I can say for sure that you can dry fit a piece with dominoes and it will hold together indefinitely while you pick it up, turn it over, etc.  No need for clamps there and that's huge for me.

Curious to hear if others have the same view.  Anyone out there routinely do domino glue ups without clamps?

Here, I suggest to the option as to avoid extrusion of the adhesive http://festoolownersgroup.com/festool-tool-reviews/domino-xl-hits-the-us/90/

I agree that you do not want to starve the joint and use an adequate amount of glue...I spread all side of the Domino and on the inside of the mortise walls...if you put glue on the lower half to 1/3rd of the Domino, it will spread itself nicely when you insert it into the mortise and limit the amount of squeeze out.  I then usually take any excessive squeeze out and apply it to the expose Domino, add more if needed, apply glue to the mating mortises and assemble.  I always use clamps -- sometimes you need them just to squeeze the assembly together and it is cheap insurance.  A razor blade works great to get any squeeze out our of corners and tight areas and follow with a damp cloth.  This can raise the grain so you may have to go over the piece with your finish sander to smooth everything out -- my tool of choice here is the DTS400.  This is what works for me.

I just did a glue up of 3 boards for a table top using the Domino joiner. I spread glue along each joint face with a little inside the mortise on each board. Then I inserted the dominoes into the mortises on the first board and utilizing the same glue brush I spread the excess that squeezed out on the protruding dominoes then fit the two boards together. I had some squeeze out but not anymore than if I was using biscuits. I try to get the majority of the glue from the squeeze outs off both sides of the boards using a rag before it has a chance to dry. Once dry, what remains is normally quite easy to remove with sandpaper. Then once I'm done sanding, or so I think. I wet the surface with either water (if using a water based stain) or mineral spirits (if oil based), looking at the surface with a light on it. This usually allows me to detect any leftover glue so I can sand it off prior to staining. Hope this helps.

Just curious if Festool would ever offer a pre-glued line of dominos as is already available in dowel form.

Could make it faster, easier and smarter, And in relation to glue squeeze out, cleaner too

Captainwrinkles ...I followed the link but how do you get the glue to activate??

Thanks,

Its set by wetting it. so a spray or couple of drops of water in each hole is all thats needed.

Glue up is greatly simplified if you use the medium setting for most of your joints and carefully glue the tenon in the middle of one half of the joint.  You can clean up and glue around the tenon right away and you have half as much glue to deal with during final assembly.
