swapping spokes (and maybe rim) to an older hub
Currently I am trying to maintain my old 80's Nishiki, where the rear wheel spokes are showing wear (breaking). I have another wheel, which I sadly put in too much money into, and is laying around.
Question, if the hub are "nearly" the same size, could I swap the spokes and rim to the old hub from the new wheel? Would I run into dishing problems? Whats the tolerance in length with spokes?
Why not use the new wheel? Its a fixed White Industries Eccentric ENO thats 135mm, where the Nishiki is a 126mm.
Thanks

Probably not. If the ENO hub has a slightly larger flange diameter, then you might be able to. The best thing to do would be to figure out the spoke length you would need, and measure the spokes you have. If they're within a couple mm, it would be worth a try.

ERD (rim diameter) and hub flange are the important measurements. Both would need to be very close to previous wheel for the old spokes to be usable.

Actually, given that spokes are generally tangential, there's quite a bit of leeway with hub flange diameter.
If they look a similar size, I bet you're good to go.

I replaced an older burned up Shimano 600 front hub with a new Shimano XT that I grabbed on ebay. The flange numbers were close, and obviously the hole count was the same, so I picked up the XT for $15 or so and swapped the rest over. That was over a year ago and I've been riding the heck out of it ever since. Great hub, and it was my first real (non-radial) wheelbuild and got me started in my interest in wheel building.
I'd take measurements to make sure that you're within a reasonable margin, but if you are, I say go for it. If possible, try to rebuild using the same lacing, and keep the leading spokes leading, and the trailing spokes trailing so that you're not re-bending the spoke ends for proper spoke alignment.

Yup. Slightly bigger effect with radial pattern which you might have on non drive side (doubt it). But rim diameter is easier to get wrong just eye-balling it.
