I'm not sure where to put a reply in this great thread, so I've started
a new one... ;-)
If a person were to build a wheel from new components, how could s/he
answer some of the questions this thread has highlighted?
For example, I think I read jim beam saying 95 degrees is about right
for a spoke elbow in a wheel. Could a person show this to be the case
(or not) by photographing a wheel at some stage during assembly, or by
showing a hub with (say) dowel pins in each spoke hole to reveal spoke
holes whose axes are all parallel (or form a cone), etc.?
For another example, I think I remember Jobst Brandt saying the holes
in the hub flanges take up the shape of the spoke as a result of normal
spoke tension, so no significant additional hub hole forming (bedding
in) takes place as a result of squeezing spokes. Could someone building
a wheel with new components take a series of pictures of a hub hole
deforming as spoke tension is slowly increased?
For a third example, I seem to recall Jobst also saying spoke elbows
take up a different angle after tensioning (in a wheel) than they had
when new. Could someone photograph a spoke before and after installing
it in a wheel to show this to be the case or not?
What, specifically, could a careful person do while building a wheel
and what kind of pictures could s/he take to illuminate some of these
questions?
