Hi all, I got a longbow off ****, looks okay and made a flemish string (which I have made many), strung bow, but bow slowly comes back relaxed and will not stay strung. I twisted string up some more and tried again the same. So I made a endless loop string put it on the 65" bow string was 62" and same thing. Thinking might be a twisted limb, but wanting to see if I am missing something? Did notie that the upper loop was not sitting in grove right, so made another with smaller loop same thing, this is why thinking twisted limb?
