I didn't mean it was breaking spokes. They just start to "ping" a bit. I just snug the loose one up till it feels similar in tension to the ones close to it (on the same side of the wheel). Not very accurate, I know. I then clamp a pointer on the rear rack and take care of the side to side "runout". I suppose if that continues, I will need a truing stand to rebuild a wheel! I don't thrash the bike on or off road. I don't hop up or down curbs. I'm a bit of a clyde at 220lbs.
Learning how to build wheels sounds like a fun project. Don't know if I can justify the stand mentioned. Would one of the less expensive ones work out for someone not really in the biz?
