At 63 cm. with those string sizes I'd say you are already a bit on the high side, tension wise. I would never take 63 cm. up to 440 with those strings without clearing the safety issue with the builder. You don't want the bridge going on vacation while your builder is on vacation. I like Dan Larson's tension calculator:
http://www.gamutstrings.com/calculators/calculator.htm At 63 cm./A=440 and leaving his default tensions in place his calculator comes up with: g-.40, d-.46, a-.62, f-.74, C-.98, G-1.28 & g-.64 -all based on gut, which is virtually the same as Nylgut Hope this helps- Dan On Oct 20, 2011, at 12:27 PM, Gert de Vries wrote: > Dear all, > > I have a little problem, my lute maker who always helps me with my strings is > far away till december. > My lute is tuned in 415, and I need to go to 440, and I am really bad in > calculating, so maybe there is > someone who is able to do that without too much effort?
