Hi, I have researched Federer's racquets over the years and decided to attempt to replicate this as close as possible for fun. I know it is actually impossible so keep in mind that this is just for fun. Tell me what you guys think High-res links are available on request Changes from the stock nCode 90: 1- Using Wilson natural gut on mains @ 47lbs 2- Using Lux BB on cross @ 43lbs 3- This frame has 4 crosses on PWS like Fed's unlike the other stock stick which has 5. Since this racquet has 4 crosses on the PWS it requires the same differential cross spacing that Fed uses for stringing. 4- 4gr of lead tape added into the head on off-set positions to counteract differential balance. If looking from top of the racquet the bottom lead tape on the head is inserted at 1 o clock and the top lead tape is inserted at 11 o clock. 2grs used on each side. All this means is that I did not add 4gr in one giant pile and also did not split 2gr and 2gr and install them on identical positions at 12 o clock. 5- 10 string savers installed on 4th cross down and 4th main down. Federer uses an off-set pattern. This means that the 6th cross is started one main further in than the cross pattern on the 4th cross. 6- Wilson stencil added lower than stock to match RF's 4 cross PWS setup. The top of his stencil starts on the 6th cross and covers the second row of string savers. 7- Power pads installed on bridge. I bought a 30 pack of leather pads online and used a sharpie to color them black 8- Wilson pro overgrip. Extra padding was added in the butt to mimic Fed's wrap and I tried to match his overgrip spacing. The grip (from bottom) starts with heavier overlap and becomes more regular as you go up the racquet. 9- Black tape at the top of the grip. I used black electrical tape at the top of the overgrip to mimic Fed's wrap. This actually works very well if you apply the tape and really stretch as you go around while slowly making sure that you overlay the previously wrapped row. About 3 rotations is sufficient. 10) Custom ties. This is a crucial and difficult part to Fed's setup. His stringing ties are very different from the stock setup and this is for a few reasons but also has to do with his 4 mains @ PWS. This string pattern is especially important for the starting cross tie on the top right. This would normally start on the first cross on the top right but Federer has it starting on the second row which relieves pressure on the first cross row which is where strings commonly break. There is an entire thread about this somewhere on TW. Tie locations: Start cross: Right side second row down cross. End cross: Left side second row up cross Start main (gut): Right side second row in mains End main: Left side second row in main The racquet is now the exact weight as Fed's racquet Strung weight: 360g (RF 360.5g) Swing weight: 330g (RF 330g) The stock stiffness is not far off from his to begin with. Stiffness: 66 (RF 65) Entire racquet https://sphotos-b.xx.fbcdn.net/hphotos-frc1/465645_10200226421002572_1344187327_o.jpg View from butt: https://sphotos-b.xx.fbcdn.net/hphotos-prn1/530722_10200226426122700_1489147884_n.jpg String bed: https://sphotos-b.xx.fbcdn.net/hphotos-ash3/736436_10200226443643138_668689918_o.jpg String saver setup: https://sphotos-b.xx.fbcdn.net/hphotos-frc1/736474_10200226451963346_787290957_o.jpg Bottom left tie-offs: https://sphotos-a.xx.fbcdn.net/hphotos-snc6/280599_10200226461123575_881753113_o.jpg Bottom right tie-offs: https://sphotos-b.xx.fbcdn.net/hphotos-ash4/411929_10200226468083749_456013538_o.jpg Top right tie-off: https://sphotos-a.xx.fbcdn.net/hphotos-ash3/736376_10200226474843918_1136839339_o.jpg Power pads close-up: https://sphotos-b.xx.fbcdn.net/hphotos-ash3/620434_10200226477403982_1184044570_o.jpg Close-up of racquet side showing custom stringing setup: https://sphotos-a.xx.fbcdn.net/hphotos-snc7/416680_10200226482604112_748513380_o.jpg Handle close-up with black tape: https://sphotos-a.xx.fbcdn.net/hphotos-snc6/280745_10200226486804217_1553949960_o.jpg Power pads alternate view: https://sphotos-a.xx.fbcdn.net/hphotos-snc6/266967_10200226494524410_1595300321_o.jpg Again this setup is just for fun. What do you guys think If anyone wants any detailed information please let me know, I would be happy to share how I set this up.
