Pneumatic Domino Joiner
« on: June 18, 2019, 06:37 PM »
This Australian woodworker reported that he could not get the kind of accuracy he expected from the four domino joiners he owned. He came up with this to enhance the machine's accuracy:

I cannot for the life of me, think what this guy is making that requires more precision than a factory Domino provides?
Perhaps like a good few users I’ve seen, he is not great at keeping the machines still whilst plunging?
Personally, if I were going to those extremes, I would use a traditional mortise and tenon approach.

Each to their own though.

Looks like an excellent high volume production adaptation of the Domino. If I was doing hundreds of identical mortises, this wound be a great timesaver.

Interesting from a production standpoint...I'm glad he's got 3 other Dominos because this one isn't going to be moved anytime soon.

Could be useful for small parts, especially if there are a large quantity. Anything larger than a couple of square feet will void whatever increase in accuracy the fixturing of this machine provided.

This is not said to diminish the guy’s ingenuity.

I did not go into finding out what accuracy issues he has had with his units (he did say they were not confined to one joiner), but suspect that some calibration issue or the lack of it might be the culprit.

Looking through his feed he is clearly a talented craftsman. But I'm with @Jiggy Joiner . I can't imagine what the machine can't handle without such a contraption.

Hi Chuck, Although this chap may well be a fine craftsman, he might have a not so fine technique with his Domino machines?
I have a colleague that is known to be one of the best cabinet makers out there, his work is on another level.
However, I have seen him operating biscuit joiners and also his Domino machines, in such a way that apart from his age, he could be mistaken for a fresh apprentice!

He can cut any joint by hand better than most, and the continuity would give the impression he has top precision jigs but, he and some power tools don’t marry up very well. It’s like a respectful joke among us that know him well.
I have also seen others doing similar. A chap I used to do a bit of work with first showed me a Domino machine in the flesh. I asked him how he was getting on with it, and he said he was still getting used to it but, years later he, by his own admission struggles with it.
He tells me it should have had a slimmer body, and larger front grip knob amongst other things  [big grin]

The guy in your clip may well crave more precision but, I find the standard machine, providing it hasn’t any faults, to be more than precise for anything that’s asked of it.
Any faults or problems I’ve had when making anything with my machines, have definitely been my fault, and not the Domino.

I guess his machines may be faulty but, four different machines would be rare I’d imagine?

I wonder if he’s a member here?

I think I can understand his needs.

Eh, just looks like someone having fun with some pneumatics. Nothing wrong with that, they can be a lot of fun to play with!

Looks like he wants dead-accurate results for multiples like chair components, doors etc, without stuffing around with pencil marks and the inaccuracies that can bring. Can't see how this turns into 'he doesn't know how to use his domino properly'.
