    about to match four rackets, add a little weight, etc.

    do you feel it's necessary that they all be strung with the same string?

    in the past i have done so, but now I have four sticks with different string setups in them....

    FWIW, they are all syngut and multi (2 are 17g, 2 are 16g).

    thx folks.

    Gettings the grips, dynamic tension, total weight, and balance points all the same shouldn't be hard. I wouldn't go as far to get all the swing weights the same since they're all different anyway.

    rackets are all gripped alike (leather with an OG) so they are mostly setup how i want to start with exception of matching stringjobs.

    just curious if anyone has insight as to whether i should string them all the same as well before starting.

    the idea is to get them all matched, THEN i'm going to try CAPs on one (and further balance etc) to see how i like it (MG Rad MP's).

    If you can, match the match the frames' mass and balance point with the same grip and OG combination. Do it while unstrung. Then string the middle 2 mains and the top 2 crosses and determine SW. If you have access to a machine that can do RDC, then you're good already. Finally match SW. 2 cents.

    addendum: Saw that you wanted to 'cap' one of the frames. Are you trying to match the 'capped' frame to the 'un-capped' frame? If that's your intent, then maybe you should install the cap grommets before starting to match the frames. Another 2 cents.

    I'll be doing it with a scale, balance board....and the TW swingweight calculation method.

    So, you are saying i should use unstrung rackets essentially (to start matching)?

    I have always done them strung in the past, but they were all strung alike (not the case as they currently sit).

    Yes. The mass of the string if you're using different gauges will vary +/- 1-2 grams, which will affect SW. If they're already strung with the same string currently, then match them up as is (with strings.) Just be aware that if you change strings or gauges, you're going to feel a difference in SW. For example, I can feel the difference in SW when using 16 Ga vs 17 Ga.

    Match them unstrung and without OG's. If you have the same replacement grip on all frames, tha'ts good. If not, remove them and match without the grips.

    I appreciate that if you put the grips back on it will affect weight/SW/balance; but you need to work from a 'base'.

    Once you've got the rqts matched, then CAP the frame you want to.

    Regards

    I guess it would depend on where you are putting your weight. If you are going to put it under the grips and grommets, so the lead tape does not show or inside the frame so it does show. If you can string all four rackets so the length if identical on each and after string without changing SW then you are better off bale cling all rackets without strings, grommets, or grips. But then when you put on the grips, grommets, and string will you mess up the SWs? it is easier to match the SWs with everything done.

    You won't know that until you start to work on them

    If you're going to remove grips and grommets, then you need to check the specs at each stage.

    When I've matched my racquets, I've always removed all 'consumables' - so no string, grip or grommets. I figure that sooner or later I'll have to replace them, so I'm better off working at the lowest level.

    Whether this works depends on a couple of things:

    - are your consumables fairly consistent (for instance, if you buy two sets of identical grommets, are they actually identical)? If you find they vary, it adds an extra level of customisation. FWIW, in my (somewhat limited) experience, I've found my grommets and leather grips to be pretty much identical, but when replacing Head pallets they've been all over the place, even when ordered in bulk from the same supplier. My worst was a batch of 4 sets that ranged from 18 - 23g.

    - you're more concerned with making the racquets match than hitting very exact specs. I start out with a target, but don't mind too much if I miss by a bit when everything is done, provided the racquets are the same.

    No you don't want them strung because to match them you will have to add lead to different points. At some points this might be under the bumper guard so string will force you to cut it out.

    I would match for weight, balance and swingweight. I have a prince PTC so its easier, but these are the most obvious.

    I have matched 2 of my dunlop biomimeti max 200G.

    the 2 racket of my dunlop is currently strung with same string and same tension. the only different is one without replacement grip and the other one with replacement grip.

    so I remove all the grip but not remove any string. from there I calculated only static weight and balance.

    the 2 of my racket is in the same balance but different in static weight less than 2gr. than I give the lead tape in the throat of the racket to add static weight but not change the balance.

    after it have the same weight, I put 2 exactly same replacement grip. viola.... now my racket is 320gr strung weight and 4pts HL.

    when I change the string from 17G to 16G the static weight is up 1gr. but the balance is not change at all.

    I think every one has their own step to matching a racket. and I think it best matching it with same replacement grip without the string. because it has different weight when you strung it with different string.

    This video is a great guide to matching. A postage scale which does 0.1g increments is extremely helpful: even a 0.5g difference can really throw the feel and balance sufficiently off.

    ok. i do have a science background but i have one in logic as well.

    if i just match weight and balance, swingweight should be damn close already. no?

    Not necessarily. The balance point is created around the middle of the racquet. Take two identical frames: on one of them add 5g at either end, and on the other, add 10g in the middle. Both will still match on weight and balance, but swingweight will differ due to the distribution of the weight.

    In practice though, you're unlikely to do anything that extreme, so unless you're starting with quite different specs, you'll probably be ok so long as you use some common sense. (either that, or I've just got really lucky when matching frames. :))

    MG Rad Mp's.

    Mine are all within six grams naked, leather grip only no strings (305-311grams, 4 rackets). i'm just gonna start by bumping the heaviest one barely (also the the least HL) then match the rest, as a starting point.

    after that, i'm gonna cap 2 of them and fool around.

    i'm trying to use the TW tools to match some sticks with little luck so far.

    if i spit out some numbers would one of you racket gurus give me some baseline to work with?

    I just want to match at the bare minimum, if you will, then i can go from there.

    thx in advance.

    I did some videos on this once. You should try to weigh the handle of each racket (measure each at the same point say 10 cm from the butt or 4" from the butt) with the head supported at constant point (say maybe where you want to add weight. Then support each racket where you weighed the handles and measure the weight where you weighed each head. Add weight on each of the latest rackets until all handles weigh the same and to each head until each head weighs the same. The total weight should also be the same, the balance will be the same, and the swingweights will be close. If you wanted to change the balance add more weight to either the handle (for more HL) or to the head (for more HH.) also make sure the overall length of each racket is the same.

    tbuggle while I am thinking about it if you add weight to the handle the swingweights may be off a little but the balance point will be the same. But since you are using the TW SW (I assume) where you add the weight will not change the balance that much but will change the SW. Use the TW SW method to determine exactly where the rackets swing at the same period and your rackets will be matched.
