Had a set of wheels built at my local shop. Ordered the track hub and rims, he took measurements and I ordered up the cut he said to. Got 'em laced up and what do you know? the spokes are a teeny bit too long and there is no more thread to tighten them up so needless to say, I'm a little f'ed here until I fix it right. Can anybody tell me exactly where do I measure the spoke length? I imagine it would be from the center of the hub hole to some magical poiint at the rim. Since the wheels are already laced it shouldn't be too difficult to take that measurement myself.

Thanks all, NAES

From Sheldon Brown:

"Spoke length is measured from the inside of the elbow to the very end of the threads, most usually in millimeters."

If you go to this page:

and download Spocalc, it contains just about every rim and hub in it. You can then punch in the numbers and it will tell you what length spokes to get. It's a very handy program!
