[pianotech] String scaling was BB Mason and Tenor Cross over

[erwinspiano at aol.com]

Understood. All good points.
  I have had sets from them for 9 fts that were not double wrapped and so I know what they sound like. I had two Ds side by side, one with and one without and I prefer the double wrapped...whatever they may be doing. Yes, I would enjoy running more nos. 
  BTW, I have also had the sets where note 9 or 8 and 9 were single wrapped and the bottom end were double wrapped and I do notice a difference that is displeasing to my ear and tonal balance of the scale.

I guess the question is whether the double wrap was responsible for the sound you like.  I would doubt it.  Arledge usually reduces the core dimension on that piano as well to about .055 (I think—they’re not making my strings or doing my scaling so I’m not sure).  I’m not really convinced that the double wrap or single wrap makes any difference in the tone.  It’s the relationship of core to outer wrap that makes the difference.  In fact, I believe that the Arledge program has a built in for determining if the strings are double or single wrapped and it has, again, to do with the core to outer dimension relationship.  I can recall having them do a set for me some time ago and my specs translated by their program called for double wraps on 1-9 but by the time they got to string #10 the specs on the wrap dimension had come down enough to fall into the single wrap category so that’s what came: 9 double wraps and then one single wrap monochord.  There was no discernable difference in tone between string #9 and string #10.  I believe the problem is that if the outer wrap copper is too thick for the inner core it will tend to come loose more easily thus the decision in such cases to use an inner wrap.  Correct me if that’s wrong anyone.

Actually the first double wrapped Mono-chords I experienced on a 9 ft. Stwy was for me a happy accident. I simply gave Chip at Areledge a memo saying unless further notified send all Bass mon-chords double wrapped. I actually didn't mean for him to do the 9 ft this way but when I got back to the shop.... they were on and it turned out I like it. It was David Andersens Stwy D ....ask him his opinion.

I specify "monochords double wrap where possible", and haven't seen a double wrap come back for a 9' piano yet.
