The small twist drills we enjoy use of today are not in fact erquired to make those small holes, any bit of wire (even brass) can be sharpened and made to drill holes. Flaten the end and file it into a diamond point and you can have whatever size hole you require. Leave the wire long enough to be flexible, spot the hole location with an awl to start it, and you can even flex to the angle required for the hole. > d) the dying of silk was never called 'in the past loading of silk' but > just 'dying of silk'. yes, silk can add till 300% of its initial > weight; the problem is that there is an increase of its volume also.

At the end I understood that it was not a way. there may also be an issue with US law, apparantly textile silk is limited to 10% weight increase for garment use, dont know if musical instrument strings would be covered or even if anyone in officialdom cares, but should they take an interest we had better be prepared to argue in support. > -------------------------- > 2) I checked 70 lutes from which only 50% I had to suppose with > original bridges. I dont think original should be the concern; if the set of holes in the bridge was conceived to one plan then it is of interest. -- Dana Emery To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
