domino not mortising in the centre between the side flaps

[mosez]

when mortising using the right paddle as a reference on one workpiece and then mortising using the left one on a different workpiece, i dont get a flush joint. this means, the distance from miy right paddle to the center of the mortise is different from the distance from my left paddle to the center of the mortise.
this cant be correct, can it?
i already sent my domino in because of the problem, they say its not an error and thus cannot be repaired.
im actually really frustrated about this because when making an edge-to-face joint you always use the right paddle on the edge of the vertical board and the left one on the edge of the board that gets its face mortised, right?

You are right, the distance has to be the same for the resulting corner to be flush. I have the previous model of the domino (no flaps, but pins, one of them is located in an excentric bushing for calibration).
I believe the version with the flaps came with an extra piece of a different thickness that can be used to replace one of the other flaps.

/edit: The calibration process is described on page 21 of the supplemental owner's manual

At least now when i get my own Domino i know everything about it before I even use it. Thanks for the link Frank. But now you just made my pocket feel to full. [blink]

ive read the supplemental manual a trillion times and its great. and it sure isnt ricks fault that festool comes up with such a pathetic idea to remove a more or less random offset with an offset dog that has a certain width. if there were at least different offset dogs...but there are not. the only offset that you can effectively remove is 0,15mm. and if the domino would have such an offset right after fabrication i would expect festool to change the dogs themselves.
but it just isnt 0,15mm in my case, so there is NO SOLUTION??

I dont know why festool didnt make the stops adjustable from the get go, It only seems like the logical thing to design them that way. The only thing that i think you could do Mosez is to trim down the stops yourself.........maybe with a dremel tool or make up a jig that the stop fits into so you can trim it on the table saw. Im sure that would work.

Why don't you cut the second mortise using the wider mortise setting? This will cover your offset difference.

no richard, it wouldnt solve the problem!
the first fix domino aligns the pieces, no matter how much space i give the other ones to move...
wayne, were talking about something smaller than 0,15mm ^^ i dont even have a table saw (i have a dremel on the way though) and i can hardly imagine doing such precise cutting on such a tiny piece of plastic...
but thanks anyway the dremel might be an option...

Ah your right there 0.15mm is a bit to tiny i think to even try with the dremel. how about using a very fine file......or even sanding it ever so slightly???

 

[mosez]

that might really do the trick...thanks for the input

Hello,

I had the same problem with my domino.
The reason why Festool has changed the design is a patent problem.

I have solved the problem as following:

Take two pc. wood and use the right and the left during mortising. (Mark on the wood which back stop you used)
Fit the wood together and gauge with a caliper the deviation.
Exchange the respective backstop against the one which is delivered with the Domino
If this not helps take a key file and remove exaxtly the half of the gauged fitting error from the respective back stop.
(in my case it was 0,07mm only)

Good luck.

danke

i sent it in a second time. i thought id file it down when it comes back unrepaired again. what they did is adjust the excenter, thereby "moving" the mortise laterally. it is now DEAD ON.
i recommend everyone who has the same problem as i hade to send his domino in and ask for the excenter to be adjusted.
