At Balfour’s suggestion I’ve started a documentary to share with y’all of this project. (I usually do that anyway for my records but in a less readable way – LOL). Rather than take up a lot of white space I’m putting this stuff in a file on the Yahoo! group I moderate, so those not interested can ignore the thing. First step in any new design: the string band. Here are the data:
First is a rough graph of the string lengths, followed by charts of tension %tension and tension/length and finally the raw data.
It’s a 32 string high head harp, and pretty much has to be unless I were to make the bass strings silver (too rich for my blood) or wound (yuck). I chose bronze over brass because it is more easily available around here – but brass would have a similar profile.
Questions and suggestions are most welcome; it will be a good while before the data starts to turn into wood and metal!
