I am using Barnett's ( very good long-term investment!) as a guide to wheelbuilding and frankly, the section about tension meters freaks me out!

As to rim quality, this was a brand new Alesa 9017, box section rim, which seemed plenty strong, but i guess it's pretty low end, because I didn't pay a lot of money for it. Built by LBS with double butted stainless steel spokes and a new shimano threaded hub.

I was doing a tune up on this wheel and started by making all corrections by tightening , which probably led to the spoke failure. I understand that i need the tension meter to determine whether to correct by loosening or tightening (except when correcting radial of course). But I seem to suffer from impatience ( and I considered myself sooo Zen and patient :-) and overcorrecting which leads to more errors.

Question: If you do break a spoke when truing, doesn't the loud snap and the rim basically popping outward and to the opposite side of the spoke that snapped create so much stress/deformation that when you replace the spoke , equal spoke tension cannot be achieved anymore and wouldn't I just be better off buying a new rim right away?

Long story, but I do have another question: how much do you turn the nipple to correct an error generally? I'm prone to half turns, but I guess that is leading to the general overtensioning and spoke failure. Oh and I'm using the Tacx Exact truing stand
, is that any good? I'm not finding it very ergonomic to work with. Does anyone use it?

Thanks for all the replies!!

Well while building for a rear wheel I correct all problems by tightening but i tolerate errors to the the left since its going to be dished that way anyways. What i find a tensiometer most useful for is the final product. Often i find with my own builds that the two spokes which make a "pair", well one is loose and the other tense. Too tense.
Half turns are oaky in the preliminary. BUt if you use all or mostly half turns, your only creating problems elsewhere. Usually when my wheel is within 2mm of being dished i switch to quarter turns
