There was a good person who had been my Lathe Learning Instructor. He had a BSA and always rumbled the gear attached to the dynamo. He thought one of them was out of cycloid. But looking at his measurements, especially from the plate that held the dynamo welded to the frame, possibly this machine had an accident, warping the alignment of the gears, causing all the gearing problems.
That is a very long winded way of getting the offset, and makes a very simple job seem very complicated. The correct offset is when the rim is in line with the frame top tube. You dont need to measure it, you can clearly see it, and you tighten the spokes with the wheel in the frame with a pointer or clothes peg on the frame.
Mr. Alan Moore, how can I ask a question about drag angle or trail in relation to the inclination of the telescope crossing the wheel axis parallel to the ground. What is the angle of the scope on the frame and forks? Do I need your email if possible? The Ariel Twin KH has great directional stability. That's why I want to know the angle in degrees accurately.
