Thread: Angled mortise with domino

I would use the bottom of the domino to reference my vertical position.

In the case of a 90° drill the domino centre is offset 10 mm above the base. You would need to do a test cut to see what the offset is at your angle as well as supply an appropriate packing piece to fill the gap between the fence and the work piece.

I don't think it was designed for this sort of cut but at 10 degrees it probably works fine as long as you calculate your baseline to bit center distance (easy to test on scrap). Like you said, there will be a gap between the tool and the workpiece which would get larger the higher angle you went to. For low angles like this it would probably be stable enough but much higher it would be a struggle to keep stable i'd imagine. I'd clamp a scrap across the base line that the domino can rest up against so that you can concentrate on the side to side location. Typically the domino mortise is 1mm or so deeper than necessary but worth noting that as the entire tool face isn't touch against the work piece the mortise will be slightly shallower.

Rather than this method, if i had to use domino's for this at all, i'd just mortise it with the fence at 90 degrees, as normal, on the underside of the stool/step then cut my leg with a 10 degree angle on the top and domino perpendicular to that 10 degree (Now an 80 degree edge?) face. The domino would not be running parallel to the leg as they do in Marc's example, though. Kind of running out towards the edge. His would probably be stronger.

Yes the domino can be used for this, I have used it on 45 degrees. I am not sure how easy/difficult it is with the 500 machine, I have the 700.

Yes there will be a funny gap, but with practice you will know where the drill bit will enter the work piece when set at an angle.

Interesting - if the fence is on 45 does that mean the bit plunges at 45? Or does it take some trial and error to set up? Also any tips lining up the machine to get the bit to plunge where you want it or is it just trial and error again?
