Used the spoke set from Classic Honda Restoration (Buchanan's Spokes).
Today I started to build my rear wheel and after some truing, all the spokes are protruding through the nipples.

Laced them up correctly I guess.

Left: front spoke (OEM Honda)
Middle: rear spoke (OEM Honda)
Right: rear spoke (CHR - Buchanan's)

Is this common, any people with the same experience? What do I do about it? File off the excess, use a Dremel?
