I agree with Alex. On the Spoke Calc site there is a way to measure ERD:
Effective Rim Diameter (ERD) is the diameter on which you want the ends
of the spokes to lie. Most people prefer it near the end of the spoke
nipple. If you want to measure your own rim (recommended, just to be
sure), then follow these instructions:



The OP has the advantage of an easy of way of calculating what size
spokes to use for his rebuild: whatever size he used + the length of
exposed thread!

Dear Josh,

You practical devil! Even if there are objections that I
can't imagine, I admire your approach.

You probably know the apocryphal story of Edison asking a
college graduate who wanted to work in his lab to determine
the volume of an empty glass light bulb.

After the slide-rule expert finished laboriously measuring
curves and calculating an approximate answer, Edison taught
him a practical lesson by filling the bulb with water,
pouring the water into a graduated cylinder, and announcing
the exact volume.

Thanks,

Carl Fogel
