[CAUT] Getting straight

[Fred Sturm]

Hi Ed,
	Jim Arledge and the Bolducs have both seemingly dealt with this  
successfully. I don't know how. I saw a slide or two of the Bolduc's  
wire dispensing rack, with some devise the wire was fed through to  
straighten it, and thought I understood what it was, but when I went  
to reproduce it, it didn't work. Probably the details have to be just  
right. I do know that Jim straightens wire.
	A lot of interesting stuff in that article. I can't help wondering  
whether, if you have curled wire, and you can't keep the curl  
horizontal or vertical, maybe putting a twist in the wire would help  
eliminate the possibility of false beats, that maybe a twist might  
counteract/confuse/break up the pattern. It was only the case of a  
curl being at an angle from horizontal or vertical that consistently  
produced the falseness, and when there was a half twist in the wire  
(admittedly a specific half twist in specific directions) no false  
beat occurred. Makes one wonder about a number of in between scenarios  
(the article only mentions specifically a string with the curl at a 45  
degree angle between vertical and horizontal, and no twist, producing  
beats).
	Nice to have the kink(s) in the wire hypothesis tested and discarded.  
Though I think most of us had already discarded it based on our own  
experiences. It will be interesting to see where the next segment  
leads. I assume we will get to terminations and shorter strings.
