Harry was my second guess.

That's all he does these days, at least for road bikes. He gave me a tour of the shop. Amazing. He has a different machine for each part of the frame. One of his lathes is from the 50s and was used by the Navy, probably to make artillery shells.

He recently built this for himself and had it on display at the Philly Bike Expo:

Cerakote Coatings: Custom Mix of H-137 Gloss White and H-169 Sky Blue

I am probably going to have my frame coated like his, only in either pink or sea foam green.
