    Could this be a faulty clamp?

    When clamping a just tensioned string always clamp the string clamp first, then make sure the base clamp is centered and in line with the string clamp, then clamp the base clamp. When releasing the tensioned string release the base clamp first, then release the string clamp. Remember the...

    string slipping into drop weight string holder

    The problem of the string getting behind the rotational gripper is most likely caused by one of two things. 1. The gripper jaw may need adjusted. The small (half moon shaped) gripper moves down when the drop weight/bar is lowered. The movable gripper jaw should be loose so that it can easily...

    gamma II drop weight test and adjusment

    A drop weight machine will not need calibrated, ever. The physics used will always produce a consistent result. As long as the drop weight bar is parallel to the floor whatever the weight is aligned to on the bar, that is what the tension will be. Even is the bar is up or down a few degrees...

    Is the Diablo/gripper too far below the string bed?

    You can add the spacer to the machine to get the tensioner a little higher but you really do not need to do that. The reason the diablo/roller guide is there is to provide a consistent angle of the string to the gripper jaws. As you string a racquet you will notice that as you get closer to the...

    The weight of the weight in a drop weight Gamma

    If you still need the weight for the drop weight machine I can help you with that. Our retail partners will not stock that part. Since they represent several manufacturers it is not possible for them to carry all parts for all machines. They only stock the accessories that are used regularly...

    Curved vs straight clamp base tracks?

    The main reason Gamma Sports went to a curved slot was simply to allow the base clamps to move a bit farther apart providing a little more "reach" when string some of today's racquet geometries.

    Help, screw fell off Gamma six-point machine, have no clue where from

    HI Anfield. The screw that you show is a shoulder support lock knob. It screws up from underneath the mounting arm and into the shoulder support. There's one for each of the four shoulder supports. I can help you order replacements if needed. They are not expensive. You can email me at...

    Clamps moving a lot

    In my previous response I mentioned tightening the 17mm lock nut to adjust the base clamp, however after seeing your video you have a very early model Progression machine. The base clamps on that machine have been out of production for several years and the base clamps are no longer available...

    Clamps moving a lot

    It sounds like the base clamp probably just need adjusted. Never, never, never, remove the base clamp lever and try to adjust the clamp from the top, teh sadjustment should be made from underneath. Leave the base clamp on the turntable and look under your turntable and you will see holes about...

    What is the maintenance difference of different machines?

    From a machine tech's point of view.....if it ain't broke don't fix it. Best thing you can do is just clean string clamp and gripper surfaces, keep dust off the machine, and check calibration every once in a while (couple times a year or after 40-50 racquets). The "maintenance" issues I get...

    Tighten clamp base on Gamme 6900els

    The 17mm lock nut has a nylon insert that helps secure the threads. It sounds like the nylon insert has broken down and is no longer providing friction between the threads. I can send you a replacement.

    Gamma Progression X-Es tension knob getting tuff to turn.

    The tension adjustment knob has a long threaded rod (about 6" long) that has a square metal block that rides back and forth on it as you adjust tension up or down. Over time the lubricant may get dirty, dry, and gummy and clog the threads making the adjustment knob difficult to turn. If you...

    Gamma x-2 uneven posts

    Sorry, but I have not seen your emails with the problem with the X-2 mounting stands. The problem could be that there are burrs protruding from the hole that were drilled and tapped for the set screws that secure the stands. That would explain the reason they are not straight. email me at...

    Gamma starting clamps trouble

    The best glue to bond a lose plate back onto a starting clamp, string clamp, or gripper is Loctite 330. It's a two part system that includes a adhesive gel and a spray activator. The adhesive is placed on one surface, spray the other surface, and when they come together the bond occurs. Works...

    How to store Gamma X-6FC with cover?

    Sorry I'm just now posting. On the back side of the gripper drum there is a cap screw that keeps the DW bar from rotating too far forward and possibly banging into a racquet when mounted. When covering the machine, back out the screw so that the DW bar will lay all the way over on top of the...

    How to store Gamma X-6FC with cover?

    The correct cover for the X-6FC is the MGSMC cover, not the MPMC. Best way to position the DW bar is up over the rotational gripper. Let me know if you have any additional questions.

    Stringing with the Gamma X-2/Progression 200

    Keep in mind that the diamond dust coating is real diamond, so it’s really hard. The grinding stone is softer than the diamond so it will be consumed as you rub the surface. Alcohol and a brush is great for removing some build up and I always recommend using that method. However, for stubborn...

    gamma progression II FC/drop weight

    It is not possible to add the manual spring winder tensioner to the Progression drop weight machine. These are two completely different types of machines and the foot print of the base on the drop weight machines is not big enough to accept the support post, winder bar of the Progression ST II.
