    yes. if you have 2 strings and you pull them with 43lbs, then they will start with 21.5 (sorry. i miscalculated 23lbs). then later on when you pull the 2nd string, it will add a few pounds but you won't get back to 43lbs. my guess is maybe you will gain back to 30lbs or slightly more.

    since you have fixed clamps, why not just clamp it and then pull 43lbs on just one string?

    It might just break it right the way. It's very dangerous.

    try clamping it on the next string instead. that will give it a small buffer. i just tried 43lbs just now that way and it held.

    you are living at the edge anyway. ;)

    btw, that looks like a sweet machine!

    kwun can you please explain how you would do that? I use flying clamps and don't have a starting clamp yet but would like to know how to pull the exact desired tension for my first two centre mains and first two crosses.

    how many flying clamps do you have?

    i have a method that needs at least 3 flying clamps. 4 will be even better.

    after giving it more thoughts, it is futile with flying clamps.

    not because i am afraid they won't hold 45lbs. they will as i have experimented.

    not because i am afraid they will become a dangerous projectile.

    but because due to the nature of how flying clamps holds the tension -- by clamping onto a neighboring string -- this mechanism will create a momentary (around 10-15 second) tension of 45x2 = 90lbs on the neighboring string. this is fatal.

    time to upgrade my machine... ;)

    Loving the safety glasses, Noah:D. The tension is so high you can see the frame dipping downwards on the first few mains - have you thought about adding a shim to the throat-side tower to keep the racket level? I'm not sure about leaving the machine pulling while threading the next main - with "normal" tensions it's probably fine, but on the ragged edge like this I'd be tempted to go as fast as safely possible.

    I think I've deduced the formula, but I won't wreck it for everybody;).

    The idea of twin-pulling is, I think, to reduce the strain on the first clamp base. Clamping the first string then pulling its neighbour, the first clamp base is subjected to the full tension of that string; with a twin pull, the base gets half one way, then the rest the other way. Clamping the first string before pulling is fine for badminton IME, but I usually use twin-pulls for tennis as I don't want my base clamp to be subjectied to an "active" 50+ lb.

    With a CP machine, you can recover the full tension on the first string by plucking or bending it and letting the machine pull the zero out that was inside the clamp. With cranks, I used to release the first clamp just before lock-out so the zero wouldn't "contaminate" the second pull. You can see this in the first part of my video.

    i don't see the need to reduce the strain for the clamp base. these are machines designed for tennis, it should take 60lbs+ without a sweat.

    The first string will easily snap at 45 lbs of pull if there is the slightest of an edge with the grommet or clamp. This is an interesting experiment nonetheless.

    Hi Peter, I don't believe so, stringing above 36lbs will result in killing ALL the grommets. You'll need to remove and install all grommets again. And I believe stringing above 42lbs will start to damage the frame. There is no point trying. To experiment stringing a racket above that tension, you'll have to basically give up that racket.

    Mark, mis-hitting(clear/smash) a shuttle with this 42~45lb+ strung racket will cause racket to implode. And When it does, the splinter from the racket might cause serious injuries. It's like having a mini grenade explode above your head. Not wise...

    Been a while that I posted here or active on these boards, but I share the same curiosity as this gentleman. Wonder when Mr. Panda will announce the revelation and let me empty my wallets HEHE :D
