Building new wheels with used hubs

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.

I would either build them in the old pattern or use spoke washers if you want to build them up different. The washers are for hole clearance issues but they are also good for keeping the old spoke indentations from causing a stress riser. Add 1mm to your spoke length if you use them.

Yep, spoke washers definantly. I think you can get them from Alfred E bike, other places too. I wouldnt do a radial lacing pattern either.

Thanks for the advice. The washers make sense--i'll be sure to get some. I was going to avoid a radial lacing pattern anyway, but was considering a variation on the 3-cross (photos not mine):

Honestly if the number of spokes is more than say 28, I wouldn't even worry about it. I have respoked and reused countless hub/rim combos within the 3-cross pattern without anything resembling an issue. Generally speaking they overbuild that area anyway. But yes, stay away from radial, due to the much higher forces invovled.

Build 3X front and rear and keep the old pattern. Even with washers, you may have reliability problems if you change the lacing pattern, because of elongation of the spoke holes in the hub flange.

I built a radially spoked front wheel in the early 1970s, long before they became fashionable, and I say, "never again"!

Congrats on scoring the used Phil hubs!
Don't worry about wear and tear on Phils; On one tandem in the 70s we put 64,000 miles on Phils; our next tandem we put 56,000 on Phils in the 80s; and in the 90s we put 57,000 on a set of Phil Wood hubs. Hubs on tandems, especially the rear one, take lots of torque .
A great American product!

As long as you do a tangent pattern like 3x your set. Go for it. It doesnt weaken that much if its a tight fit, any play though will wear the flanges much faster. BUt as it was said, add 1mm of spoke length if your using washers.
