    How to string old wooden racquets?

    The smaller the frame, the lower the tension. I would not go higher as 18kg.

    Grommetset for old Head extreme pro

    Someone came with the first version of the extreme pro (microgel). Looked still pretty good, but the bumperguard was badly damaged (not the grommets). Would "any" extreme-pro set fit this dinosaur?

    Restringing only the crosses

    I do reuse a (quality) gut in the mains. But I plan this ahead: - use knots with inserts that can be untight - remove the gutmains (after I first mount the frame, and cut or remove the crosses) - cut the gut in the middle, and ty the "old" ends to have the old worn middle part now at the ends...

    Pro's Pro Electric Power MT-200

    Trump could have said: "all stolen american technology. They steel our jobs. Buy American!" Edit: most likely that all crucial Wise-parts are "China made" already

    Do the machine towers really colapse as you string the mains ?

    The 6-12 standards are extensions of the tower...... If the head is compressed 3mm, then the 6-12 standards will be 3mm closer to eachother.

    Do the machine towers really colapse as you string the mains ?

    I still wonder: the head gets 3mm shorter, the supports still make contact, and the towers don't bend towards each other...... Edit: something in the support structure has to give....

    @Irvin, so you are saying you have no head-deformation after finishing the mains? So, the "true tension machine" is superfluous; just use a star 5.

    - measure the inner length of the head using same steps - measure distance not of the base of the towers, but between the tops

    Do the machine towers really colapse as you string the mains ?

    You don't have to "think", just read the report

    Do the machine towers really colapse as you string the mains ?

    Just a simple thought-experiment: - first main is 350mm - tensioned at 30kg, this string has an elastic elongation of 4%, so the 30kg tension is "stored" in 13mm elastic elongation, 2.3kg/mm - 5mm compression means 11.5kg tensionloss

    http://www.racquetbase.com/PDF/reviews/25.pdf Here an example of a testreport from a well reputed machine, the star 5 The top of the towers and the frame are compressed 5mm when only the mains are strung!!!!

    Do the machine towers really colapse as you string the mains ?

    - yes, the towers will bend ~3mm when the mains are done. - when the crosses are done (using correct tension) towers (and frame) are back in starting position

    Star 5 - stiff

    I know "reference tension" is "just a number". But I would like my machine to pull te SET reference tension (and not yank an extra 5#) Edit: I know Babolat makes excellent machines, but 5# overshoot.....

    Differences in tension heads

    We all know what you mean, but it would be good to use the correct name: diabolo (and not diablo=devil)

    Calibration scales

    Irvin, you know, the only (almost) constant pull is the Stringway automatic dropweight :)
