The through holes are exact width 5mm mortises, directly on top, 10mm
exact width, plunged about 3/16" .

Hmmm. I haven't used my 10mm Domino bit yet. Your 10mm bit slot looked
bigger than I thought it would have looked.

You know, the 10 mm slot is twice as wide as the 5mm slot. ;~)

And of course the slot is going to be 5mm wider/longer.

One other question. I haven't tried a through hole with the Domino
yet. Do you use a backer board when doing a Domino through hole?

I did not for those pictured and I did have a bit o tear out on the back
side. None of this is going to ever show so I was not concerned.
And I was thinking that the bit might finally be getting a bit dull.

Today I made 16 more through slots and had not one tear out. I suspect
it was the orientation, vertical, that I was holding the Domino and did
not have a real stable hold on it yesterday. I probably wiggled a bit.
Today the Domino was cutting horizontally.
