I am going to relace the rear wheel with the powder-coated spokes, and made a jig for that (if there is interest, I can make a description for the Technical Info section) .
Two questions: unlike for the front wheel, I doubt if there is a left and right side of the rim?
And two: what's the offset? Or is it perfectly symmetrical?
Why didn't I first consult that Great Green Book: "Technical Handbook - Inspection Standard" by S.J.Madden?
There it was, page 32: offset left 5/8" right side 1 1/4"...
Remains the question: has the rim a left side
The Green Book should be scanned onto the Technical Information section of this site and be available to all.
If I had a copy I would gladly do so. Instead I will offer a monetary grant to any member who is willing to do this. Please email me off line if you have any interest.
