CLUB BUILDING INSTRUCTIONS:
Unlike most golf shafts which require trimming of the shaft from the tip to achieve the required degree of stiffness, the Nunchuk’s unique design does not require any tip trimming. An integral part of the shaft design includes a specialized tip section, which should not be trimmed to fit a driver, fairway wood, or a hybrid.
Instructions for ALL NUNCHUK® Shafts
- TIP TRIMMING - No tip trimming required or suggested for Drivers, Fairway Wood, Hybrids or Irons to adjust the "flex" of the shaft..
- CLUB LENGTH TRIMMING - Butt trim all shafts to achieve desired club length. For Drivers, we believe you will get optimum performance if you do what the majority of PGA Tour players do and trim the finished length to 44 to 44.5 inches, rather than longer lengths typical of "off-the-rack" drivers.
- .350" HOSEL SHIMMING - If installing a NUNCHUK® Wood Shaft (.335" tip) in a club with a .350 hosel, use appropriate sleeve or shim available from club building suppliers like BillyBobsGolf.net, Golfsmith or Golf Works.
- EPOXY APPLICATION - Use enough epoxy to properly coat the shaft and hosel bore, but don't overdo it (because the shaft wall thickness is larger than most shafts, the internal diameter is small which does not allow much volume for excess epoxy to fill). If using long-cure epoxy to assemble club(s), some club-builders have found it useful to mask-off the hosel of the club to avoid having any excess epoxy adhere to the exterior of the club.
NUNCHUK® xi Specific Instructions:
- NUNCHUK® xi's are available in both .355" tapered tips or .370" parallel tips with a 2" tip section. For additional versatility, the .370" parallel tips are designed to be carefully sanded to achieve desired .355" taper, if needed.
- IRON SWING WEIGHT ADJUSTMENT – As with most graphite iron shafts, clubs can be built ½" longer than standard to achieve desired swing weight. Alternatively, lead or tungsten plugs designed for graphite wood shafts can be used to increase swing weight (note - we suggest trimming the shaft tip to offset the length of the flange on the weight plug if used to adjust the swing weight, typically no more than 1/8" to ¼").
- IRON SWING WEIGHT – We believe that male and female golfers will get optimal performance with swing weights in the range of C8 to D1, which is somewhat less than many OEM clubs (note – this is a recommendation, shaft will perform well at higher swing weights as well).
