Domino alignment with horizontal to vertical joinery

[jacko9]

Hello - I've been constructing my second cabinet with the Domino joiner and have found the same issue with alignment.  With the vertical to horizontal cabinet construction after cutting the horizontal cuts, I start cutting the vertical piece cuts and after the first cut, the alignment pins seem to register the Domino off 90 degrees?  This only happens when I use the pins for spacing, do I need to align the pins?

I guess I haven't been to clear as to the problem so, let me try again and I have added a picture showing the mortise spacing that I'm working with.  I have been using the 5x30 size tenon for this cabinet construction where I index the first cut off one edge and use the pin spacing to cut a row of mortises as shown in the picture.  When I go to cut the shelf mortises, I again index off the datum edge as in Rick's instruction (page 17) and when I go to cut the second mortise using the pin to index the spacing, The Domino's face won't push up against the side edge.  The pin is somehow holding the joiner away from the reference edge.  I guess I might have to set this up and take a picture to make this clear.  This might be operator error but, I know the bottom edge to face on the joiner is at 90 degrees and I know that the two cabinet pieces are at 90 degrees, any other suggestions?

Im not sure I understand exactly what your are trying to do but if you havent calibrated the pins you could have issues with misalignment when joining. there is one fixed pin and one adjustable. Rick's online domino manual go over that. The threads on the set screw are locktited at the factory so be careful not to strip out the head of the 1.5mm allen head set screw. I had a bugger of a time getting it to loosen but it did finally get loose.

Eiji, If you look at Rick's manual om page 17 he shows a horizontal shelf piece being joined to a vertical wall piece.  My issue came when cutting the slots on the vertical wall piece when I used the pins to index the next cut, the face of the Domino joiner didn't rest firmly against the "bottom" horizontal shelf piece.  This only occurred when I was using the pins to index the slots.  If I just marked the slots with pencil and cut as shown, I had no problems but, when I used the pins to index the next cut, the joiner drifted away from the horizontal piece.  The pins are calibrated for side to  side cuts with no problems but, when trying to cut joints like on page 17 of Rick's manual, I can get a straight cut?

Can you clamp a straight edge across the workpiece and use that as a support? I have been building a cabinet just like this recently using this method.

When cutting slots on side piece I place the piece under the rail on my MFT and hold the domino base against the back edge of the rail.  Its quick and easy and guarantees the slots are aligned as long as you keep the base firmly against the rail edge
