Cool. I was wondering about the Tension Meter. It's sounds easier than tightening/adjusting the spokes by musical notes. I think I will pull the trigger on the tension meter. Ah..wheel building...that's one challenge i have yet to take. It's all possible, but does require some time and practice.

The brick idea is pure genius. The first trick would be to make sure the hub is 100% centered on the axle. I know i have goofed up on this once :-)
