| No, bells are different. Twisting them just breaks 'em. I'm 
| no metallurgist, but it will certainly increase tensile 
| STRESS. I don't see how it could possibly increase tensile 
| STRENGTH. Perhaps it seemed to increase tensile strength 
| because the twisted wire didn't stretch as far under tension 
| as an un-twisted wire. Rats! Another thing on the R&D list to 
| test some day. Otherwise, it sounds like yet another of those 
| old revered truths that everyone accepts as fact until 
| someone actually tries to rationally and scientifically verify it.
| 
| Maybe helps, maybe not - depending.

Nope. Doesn't help at all. Well, I do now know why my bells have been breaking.
