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.
