Re: Wire Size Calculations
By Douglas K. Rhodes
Terry Smythe inquired about piano wire gauge calculating software. Several ads usually appear each month in the Piano Technicians Journal for programs (mostly for DOS and Windows) that will perform the calculations, plus other neat stuff. The software is not at all cheap, as one could imagine given the limited market and the hours needed for development.
Alternately, I would be happy to supply my own Excel spreadsheet adaptation of scaling formulas derived by Dave Roberts that were originally published in the Piano Technicians Journal in the early 1980's. I have spent a *lot* of time working the kinks out of this spreadsheet, and it can be an extremely useful tool for scale evaluation and/or re-scaling. My version is for the Mac, though I can supply a printed layout of the formulas with their various cell references, which should be readily adaptable to any spreadsheet on any platform. In addition, I have prepared an explanatory text which parallels Dave Roberts' comments on the formulas, as well as guiding the user through the workings of my spreadsheet adaptation. The only caveat I would offer is that with either stand-alone software or this spreadsheet, there is still a considerable amount of experience and head-scratching necessary to developing good scale modifications, particularly with regard to wound bass strings. In Terry's case, where the piano arrived with no strings, I'd be happy to lend whatever assistance I can.
Financially, I am only concerned with recovering floppy disc and postage costs. If anyone is interested, drop me an email note at <drhodes@islandnet.com>.
