Festool Domino XL for external doors?

[Wizard9999]

Don't vending machines work mainly on coin weight. I understood this was why you occassionally used to find a ten pence wrapped in metallic foil, to make it weigh the same as a fifty pence.

As long as you use plenty of glue the xl is perfect for external doors I've not had problems with one's I've made and I had option to use m&t. One door I made had 62mm thick stiles and rails so that had double dominoes and I think turned out stronger than a m@t joint because the locking gear groove ran between the dominoes, this door is on a 7.5 million pound apartment in London so if we didn't trust the joint we wouldn't have used it.

I don't actually know if it was true, but it was in the old days when a coin had to go in the right hole and you pushed in the mechanism. Hang on this is the woodwork forum not the crime forum (don't use my real name on that one :lol: )

Expensive, but there is also the mechanical dominos. I think the intended use of these is for knock downs, but there is no way those would ever give up.

On the largest XL dominos, could you not drill through and dowel them as well, like a pseudo draw boarding.

Having faith in modern adhesives is the key here I think, domino/epoxy/plus regular upkeep on the paint/finish will probably give you a door to out live whoever made it - after that who cares...

I'd use a marine-quality poly not epoxy precisely because the joint is so tight on a domino. OK there is a big gap at the sides on the wider settings (but too big), but the faces are going to be starved by epoxy standards.

It would be a pretty small dowel as even the largest XL dowel isn't that wide - they only get longer and fatter. But in a similar vein on things which are going to be painted, or not seen on one side, after gluing and cramping I quite often screw through into the doms either side of the joint to free up the cramps.

a 14mm domino is circa 27mm wide so you could put a fairly chunky dowel through it.
Having said that even a small dowel will give a large amount of mechanical strength to the joint (assuming the hole and dowel size are accurately matched).
Might be even nicer to make it a feature by using brass rod for the dowel/pin and leaving the ends exposed. Would look lovely on a dark wood door in my opinion.

So you could get a what, 6mm or maybe 8mm dowel in, introducing end-grain moisture suck right into the joint. Not sure it's worth it, unscientifically.

Brass, yes OK I'm liking that more. Or just a stainless screw from the inside face and plug over the top.
