This Panda's not crazy, Panda's never strung a racket over 43lbs., honestly! Noah, yeah that guy's bonkers, 44lbs. and stuff, craziness!
Hi Kwun, Please take the following into consideration 1) Can your turn-table's fixed clamp hold up to 50lbs of force? 2) It must be a brand-new PP Ultra II, never strung before 3) You need to upgrade the U-shape grommets to the BEST ONE(please purchase from Panda) 4) Please don't use flying clamp. 5) Please wear eye-guards
singnflip4life, If you don't have a brand-new PP U2, please do not use my tension chart to string. It might likely imploded your racket while tensioning.
This is just like those videos they show of kids riding their bikes off of roofs, etc. "Don't try this at home," they say -- knowing perfectly well that a dozen 14yo meatheads already have their ladders out. Boys will be boys. Have fun. Just be sure to count your fingers after *boom*.
Actually, metal won't be able to take the strain. It's not elastic and too soft for that kind of tension...at least in a strength somewhat similar to Badminton string. The tension is ~530N/mm² for a 44lbs .7mm string, more than most alloyed steels are able to take. When you hit the shuttle, that tension increases by a great amount as well....I think kwun once tried to string a racket with some wire, it didn't go too well^^
was there something special with the first pull? you double pulled at 43lbs but never re-pulled. so effectively the middle mains are only 23lbs each?
as indicated by the amount the tension head movement at the 2nd mains, you are not getting full tension for the first pull. just 23lbs each.
I do not pull 2 string for the beginning when I string normally. I did many small changes just to make sure it will work. If I re-pull the string will likely to snap. Question is are the middle mains are at 43/2 lbs? I am not sure but that's the only way I'll start this.
