This bike was built from cheap heavy mild steel just to see if I could do it.
The rear dropouts were cut from 1/4" steel plate with a Porter-Cable Jig Saw (I recommend doing this). The tubes were bent on wood fixtures. All the tube mitering was done with hole saws. A wood welding fixture was built.
Complete painted frame with stock fork:
Seat cluster:
Rear stays and dropouts:
Some parts and bending fixtures:
