I am considering purchasing a domino machine. I was wondering if you glue in the domino's? reason that I ask is the domino appears to fit really tight into the slot, and if put glue in, you would have a hydro lock, or no room for the glue.

I currently (on casing) use my biscuit joiner, glue and then clam clamps. They work great! sometimes though I have stain grade material so the clam clamps won't work. I leave the clamps on for a few hours so the glue will set. Now and then I attach the casing to the door/window with the clam clamps attached, I'm not sold on that though as it's really heavy, but it works and gets you a perfect miter fit.

The clam clamps also hold the casing tight enough that the biscuit wobble is eliminated, but it's a bit of a pain to fiddle with that. Time is money! and anything I can do to be more efficient is a benefit.

Not waiting until glue dries would also help, so if the domino's hold tight I could attach the casing etc. right away and not wait for a few hours for the glue to kick.

What's the convention on this? I intend to use it mostly for crown/baseboard and in the future some built in cabinets.

Thanks!

Yes you can glue the dominos.  You can also glue the miters.  The fit can be loose or tight.  One thing that I have done is glue and assemble then shoot a couple of micro pins thru the domino on each side of the joint thus acting as a clamp.  Then on to installation without the wait.

Depending on the thickness of your trim and the profile of your trim, you might have to experiment with referencing off of the back of the trim which could unfortunately cause misalignment on the faces if there is difference in thickness.

I would also suggest that you also consider the 4 mm dominoes if you work in thinner mouldings.
