I recently bought a pair of used Phil hubs (36 hole), and am planning on lacing them to new rims this spring. I don't know how many miles are on the hubs, but the bearings are in great shape, and cosmetically they look as new, with one exception: the hubs have some grooving from where the previous spokes had worn against them.
My question is whether this is something to keep in mind when building them up again. What's the conventional wisdom -- Can the indentations in the flange create weak spots? Should the new spokes pull in the same direction as the old ones did? Should I reverse the spoke heads inside-to-outside? This will be the third wheelset I've built, but the first with used hubs. Thanks for your input.
