I have some experience building and truing bicycle wheels, and it seemed that it was accepted that the weight of the bike hangs from the spokes. Those spokes have little strength under compression. Back circa 1963 I took my BT7 (I think that was what it was) to Dayton Wire Wheel to have some broken spokes replaced. A man I believed was the proprietor cut out several broken spokes on my wheels, installing and painting the replacements. I believe these were original Healey (Dunlop?) wheels. This car had a couple of modifications by the PO, who actively drag-raced this car. That may explain the broken spokes. The Dayton Wire Wheel guy told me that the Healey wire wheel design was inherently weak and were failing with the introduction of the 3000 engine. My memory on that may not be correct, but he did opine that the Dayton wheel design was superior. I don't know about that, but I was a newspaper reporter at the time and couldn't afford a new set of wheels. I have a BN7 with 60-spoke chrome wires now, Daytons I believe, and have successfully replaced two or three broken spokes on one of those wheels. While I just snugged the new ones a bit, I had no sense that I was capable of truing a car wire wheel despite my experience with bike wheels. That's probably why Hendrix has such a sterling reputation, specific expertise.
