I'm building a Sun Rhyno lite rim with DT 14/15g spokes on a 32-hole Marzocchi QR20 front disc hub,
in a 3-cross pattern. I'm also using a Park tensiometer.
When I put the rim by itself on a flat glass table or a trued wheel, it looks flat. But when I put
the hub and spokes in and start tensioning the spokes, the rim weld area gets a lateral bump in it,
so much so that I need to tension the closest spoke to it by about 50% more than the other spokes on
the same side, and the two spokes flanking it on the other side of the hub need to be tensioned to
about 50% less than the other spokes on the same side. I also have trouble truing the rim (maybe
because of this) even when I slowly creep up on the tensioning. WTF??? Can there be flaws in the rim
which aren't visible when the rim has no spokes in it? I've just about given up on this rim, any
suggestions as to what can be happening here?
