Woodworking question...

Post by JMG » Sat Nov 09, 2019 7:59 pm

Other than the speed of the domino tool vs a manual dowel jig, what is the advantage of a domino vs a dowel for projects like tabletops and the like? Any structural advantage to one vs the other?

Did you lick the frog again? Are you blasting Lucy In The Sky With Diamonds? Are you still playing with that obstinate beetle that is clearly annoyed with you messing with him?

We're concerned.

Very.

I’ve not used the domino cutter, but I’m told it’s stronger than dowels and a little more forgiving on alignment.

I reckon there are a least a couple youtube videos with strength test comparisons but I've not looked in to the matter. I'd guess that dominoes make a stronger joint given the same number of connection points. You could triple up on the number of dowels and get about the same surface area for the glue and physical connection.

The appeal of dominoes - and biscuits - is the speed they offer over doweling. They're much faster to cut and don't require as many connectors. The con is, of course, that expensive, dedicated machines are required.

I watched a video a while back where one of those Russian guys with more time than money built his own domino slot cutter. Matthias Wandel (woodgears.ca) built a panta-router to cut mortises and tenons that is really slick. He can make traditional mortise and tenon joints or cut mortises in both sides of the joint and use a floating tenon like the domino system.
