19-Feb-05 I discovered there was still binding when the wheels rolled, even after I re-made all new crank arms and side rods. Feeling frustrated, I took the frame apart, pinned the left and right sides together to find out what was going on. And I didn't machine the frames, so they could be wrong. Using a coaxial indicator (a very cool instrument) I checked the front and back axel openings and discovered they were +0.006 out of spec and the left and right differed by 0.003. Aargh!
