    Hi coolblue:

    I'm sure your machine is fine. I have a hip hop too (which I got partly on the strength of william's positive review here!) and it's the same thing for me. the reason it's so hard to hold on to the gripper portion of the tension head is that when the string is getting close to reference tension (which it would be after the first drop or so), you have an opposing force of 50-60lbs at least pulling the clutch/gripper back towards the racquet in a counter-clockwise direction - meanwhile, you are gripping on to the clutch trying to hold it still and essentially trying to resist that 50-60lbs force. Which is why it takes a lot of muscle! It also will not get any easier as the machine is "broken in" because it's not an issue of the machine being too new and stiff - it's purely the physics of the opposing forces. I have strung 7 racquets on mine now and the clutch feels exactly the same as when brand new.

    The solution is the technique to use is actually NOT to hold the clutch at first, and to raise the bar to around 60-70 degrees and then while holding the bar at that angle, with the tension on the string now much much less, you can simply twist the clutch/gripper clockwise a little bit and then lower the bar again. You will find the bar now comes to rest closer to horizontal than before. Repeat the process again, raising the bar to around 60-70 degrees, twist the clutch a little clockwise, and lower the bar again till you get the dot where you want it.

    With a little practice and good feel for how much your regular strings stretch under tension, you will probably just need one or 2 raise/twist/lower cycles to get the bar horizontal, and will exert very very little muscle power to do so. I also like to wear a thin leather palmed workmen's glove on my left hand, which gives me a good grip on the clutch when I twist it.

    One word of caution - don't twist too much clockwise at first until you get a good feel for it, because if you over twist and end up with the bar above horizontal, you'll need to redo that pull from the beginning and it's quite difficult to remove the string from the gripper in such a situation without possibly damaging it.

    Also in case you are concerned, if you call Steve he will recommend the exact same method (even though I know the manual tells you to attempt to grip the clutch and not let it move, why is a mystery to me too). I know this because I called him about the exact same thing and this is what he told me :)

    enjoy your new hip hop! I absolutely love mine!

    Thanks davidm for the advice! I will try the lift 60 to 70 degree then turn the knob again. Additional question for you, did you have a hard time at first locking the cone clamps? seems I have to use alittle muscle, the machine prob just needs to get broken into. But your right, Hip-Hop is an incredible machine! Thanks William for recommending!

    Do you mean clamping onto the string or locking the base of the clamp in position after clamping onto the string?

    If it's the clamping part, it could be that you have the spring tensioners set a little too tight for the gauge and type of string you are using and so might need to adjust those a little looser (but not too loose or the strings might slip through the clamp).

    For the base part, since these are not spring assisted locking bases, you will need a little pressure for sure to tighten them up and then again to loosen after clamping. I have found though after doing a few racquets that I actually don't need to tighten them up as much as I thought I did initially. I expect though if you are stringing at higher tensions (maybe above 60 lbs?) you might need to tighten the bases a little bit more.

    One thing that got me a couple times at first was turning the base swivel locks the wrong way to tighten - that is, i was confusing myself and sometimes trying to turn them counter clockwise to tighten instead of clockwise and it almost feels like it is tightening up when you do that but it gets really hard to turn after a point (which is as it should be). Not sure, maybe that was happening to you a few times making it feel like it took a lot of muscle?

    ^^^ Yep. I had exactly the same problem. I always forget what clockwise means. haha... yeah, I meant the base clamping is alittle hard for me. Gotten to the extent that my thumb got sore. I guess i need some training. Hopefully my second racquet will take less than 2 hours...

    all i can say is that this machine is awesome :)
    and starting clamp can be used to help tension the last mains or crosses if the strings are too short

    After having my machine for over a year now I still enjoy it very much. I've had no problems with it and would still recommend it to any one. As for the starting clamp I bought one from SP and it works good. I've never used any other one so I cant compare it to anything but I've used it for just about everything. I use mine to help tighten knots, extend the string if i don't have enough or to use in a ATW pattern. Overall stringing would be a pain without it so I would definitely recommend getting one with your machine.

    Make TT better, use the Ignore List!
    Does the hip hop come with free string? If so, can you say what kinds and how many? Thanks.

    Mine did not come with any free string. It seems that SP hasn't given free string with any of their machines in a while now.

    I'll vouch for the Hip Hop as well. This is my 20th string job.. I do about 1 a week. Almost got half my $$$ back now. Well worth it, glad I didn't get the swing. Fixed clamps and the build quality is well worth the money.

    A year almost with mine as well [Time flies eh Will]
    I would buy it again.For myself and the few friends it perfect.If I had to do more sticks I'dd upgrade.Done lots of gut jobs and no serious damage from the clamps or the gripper.I add a little duct tape to soften the crease in the string on the gripper.17g has given me problems slipping and such but of course 1/4" pieces of duct tape fixed that as well.Knockin sticks off in less than an hour.All my clients say I'm spot on with the tension each time.and you really can't beat constant pull.This very thread is what sold me on it.Should include some crappy string to use though.For know im happy I'dd rather sell my HH and buy an electric instead of slapping a wise on this.Anybody put a wise on one yet?

    the thing that turned me off about this machine is the conelock system. According to a lot of reviews i would rather get spring assisted. Is there any kid of way to upgrade?

    Yeah you can upgrade but they are expensive. The cone locks are not that bad, that being said ive never used spring assisted. Try them out first if you can but in my opinion that would not be a deal breaker for me.

    yeah that is what i look for in a stringing machine as well as good clamps that diamond dusted. And unfortunately the Hip Hop doesn't have either :( that turned me off. And slippage with 17g i wouldn't that happening as all i string is 17g.

    Hi William. Hope your Hip Hop is doing well. Quick question for you. Has your dropweight gripper started to slip? If so, do you have any solutions? i can't seem to find any kind of calibration on there for this? I am hoping i don't need to replace the diamond coated surface. It'll be a pain to replace. thanks. tony

    No i have not experienced this problem. Does this happen all across the gripper or only certain parts. For me if i put the string to far on the inside of the gripper it slips and so the solution to this is to but it towards the outside. This doesnt seem to be your problem but its a possible solution.

    Trying to see if the diamond surface is wearing out. I'll give it another couple of string jobs to see. I am awaiting on SP's response as well. Can't believe SP is getting out of the stringer business.
