    The arm supports on my revo 4000 are bruising the frame...why? I don't overtighten it. I was first turning the knobs so the supports just felt snug onto the frame and when I noticed the bruising I started turning just to the point that it touches the frame. But it still does it. What can I do? If the support happens to fall on the headguard then it just bends the headguard, but like just now I strung up my exo3 rebel 95 (the support lands past the headguard directly on the frame)... I looked closely and you can see where the paintjob was slightly bruised. Not enough the chip the paint but I can see it. I considered loosening up the support even more but I don't feel comfortable because the frame would be mounted quite loose.

    Any advice would be greatly appreciated.

    What are the supports made of? If they are hard plastic/polymer, then you might consider cutting some strips of sticky felt paper and putting that on the surface of the supports that come in contact with the frame. I have an Alpha Pioneer Plus and the outside 4 supports are hard plastic. I installed some of the felt paper on mine and I have no issues with scratches or anything on my frames.

    Thanks for the reply. Yes the supports are exactly like the pioneer. What kind of sticky felt paper? Is this something you'd find at office depot or something like that?

    I think I found mine at Michael's. Any arts and crafts store should have some. It feels like felt on one side and the back side is just sticky tape. You cut it to size and stick it on. I got it a long time ago for another project and had some left over which I used for the stringer. Just get the black colored one and you won't even know it's there. They come in all different colors.

    I use the off cut from a replacement grip. It's not perfect, but seems to help a bit.

    I've always wondered whether the mounting system on higher end machines alleviate this, or whether it's just one of those universal things on a 6-point.

    Well i went to walmart and bought some of that black felt material that sticks to velcro (it has sticky tape on back) and im about to tape it onto the supports. I'll report back on how it turns out.

    This has never been an issue on my mid-range SP DG. The inside of my side mounts are a very smooth polymer material with a slight contour to them. They have never left a mark anywhere on a racquet. That would bug the you-know-what out of me. I also notice my mounts have a different shape (being symmetrical), so I think it is probably an Alpha design issue. Nice work around with the felt adhesive.

    Well it seemed to work. It didnt leave a mark on the frame except for a very small one on the head guard and honestly i can't tell if its an old mark or not. Having said that, i still think im doing something wrong. The felt i attached to the supports had a very deep indentation on them. I think the frame might be expanding too much during stringing. But i have no idea how to prevent that from happening.

    I would make sure you don't have any tower creep on the machine. Your 12 and 6 o'clock towers shouldn't be getting pulled in as you string your mains. Conversely, I would check the side supports as you pull your crosses (tends to happen a bit after about 1/3 of the way through the crosses) and make sure they're still in contact with the edge of the frame on each side. Sometimes the crosses will pull the frame tight and the side mounts will go loose. Just snug them up as you go if needed.

    Also, when you mount the frame, just snug up the mounts enough to make contact and then keep the frame from shifting around as you move it from the handle in the machine. As long as the frame doesn't move as you swing it from side to side on the table, it's good. It doesn't need a bunch of pressure... it'll take you a few times before you get a feel for what it should be.

    Thanks again for the replies. The tower creep is the first thing I checked on my machine when I received it since I had heard about this problem with alpha. Mine wasn't doing it but I'll check again just in case.

    As far as the side supports...like I said...the problem is that there is TOO MUCH pressure on them so them coming lose while stringing the crosses is not a problem. The 6 and 12 oclock posts however do loosen up in the middle of the string job so I find myself adjusting those on occasion.

    when i had my eagnas 910 (similar base and towers, screw knobs etc), i made sharpie marks on the table where there towers were for my rackets. a similar move, or a piece of tape could help see if they are creeping.

    I try to align the side supports flush to the frame edge, but also you have to work around the grommet holes. never noticed any bruising and i think i crank my frame down (6 pt) just a touch more than most folks. I slowly rotate back and forth between the side mounts and the post/billiards until snug.

    adjusting as you go is fine as long as is minor adjustments, should be able to get the racket mounted snug enough from the start, but things happen.
