So I just got a Klippermate stringer and have strung three of my racquets with it. The first one I did with a spool so I cut the string a bit long to make sure I had enough the second two I used packaged string, so 40 feet. According to my trusty manual I should cut it at 22 and 18 feet. However I seem to be having an issue running short on the 18 foot piece. so it is possible I a complete moron and cannot measure (unlikely but possible). Is there a good way to measure length of string? Also is the 18 foot mark just a bit off? I ran into issue stringing two head liquidmetal radical's OS. 18x20 pattern. Any thoughts? Just seemed a bit close, like if I cut the string a foot one way or another then the other piece wouldn't fit if that makes sense. Again I could be a moron.
