The disc brake tab is on and the dimple provided ample clearance for the rotor.

I'm rescheduling the mixte, as I have been asked to build a frame to be displayed as wall art.  And, it has to be a quick turn around.  I have ordered the lug set and dropouts from Richard Sachs and they are on their way.  After measuring the dropouts, I will order the tube set.  In the mean time, I thought I would make the head badge as I can spend the better part of a day on one.  From the day I receive the lugs, I hope to complete the frame in two weeks including paint.
