Almost finished truing on a Open Sport 36* to an NOS Chorus hub, 3X (not that the stats mater)
But then one of the nipples snapped off and the head shot into and bounce off my shirt.
I'm using brass nipples from the LBS.
I don't think that the tension was too high, but I do not have a meter.
Just got a bad nipple perhaps, but lesson is to wear those safety glasses!
