How to Properly Extend a Graphite Shaft?

Posted on September 7, 2015

Monark Golf is now offering a new system of premium golf shaft extenders to properly extend a graphite shaft and even steel golf shafts. One of the most common repairs a golf clubmaker will encounter is extending golf clubs. Extending a steel shaft is pretty straight forward. That is if you have a 0.600” shaft then you order a 0.600” steel golf shaft extender and install it. However, extending graphite golf shafts it is not so cut and dry. Graphite shafts have a much larger range of butt diameters than steel, plus choosing the correct graphite shaft extender is not based on the outside diameter of the shaft, but the insider diameter. Two 0.600” butt end graphite shafts can have entirely different sized openings depending upon the weight and wall thickness of the shaft. Eleven is far better than two In the past, graphite shaft extensions have come in two different sizes; standard and oversize. These two were to fit all the different models in the industry by either sanding until it fit the inside of the butt or wrapping masking tape around the stem or insertion end to act as a shim. Monark Golf is now offering a new extender "system" to properly extend a graphite and even steel shaft. We have 11 different color-coded sizes plus a measurement tool to take out the guesswork and have an extender that fits properly. The three largest extenders serve double-duty by fitting graphite or the most popular steel shaft sizes (0.560”, 0.580” or 0.600”). Usually this is a no-no with other graphite shaft extenders, but these are made of high-quality nylon blended plastic that is durable enough to extend a steel shaft without breaking. Graphite Golf Shaft Measurement Gauge What makes this shaft extender system work so well is the Graphite Golf Shaft Measurement Gauge. No more second guessing what size to order. To use, simply insert the gauge into the butt end of the shaft you wish to extend without forcing it in. When the gauge stops you identify the color just above the butt of the shaft and order or choose the correct size shaft extender from your inventory to do the job correctly. This will allow for slight sanding for a better epoxy bond or you can order the color code just below it. Do I need all the different sizes for my shop? The answer is no if you don’t mind the additional work of sanding the insertion end of the extender to the exact fit of the shaft you are trying to extend. The Gold (0.500”), Red (0.530”) and Black (0.560”) will be the most popular and allow for sanding the smaller sizes and still leaves enough depth of the flutes for additional epoxy adhesion. Tips to Extending Graphite / Steel Shafts
  1. Always epoxy the shaft extension in place, do not rely on a pressure fit.
  2. Lightly abrade the insertion end prior to installation to give the epoxy a better hold.
  3. Make sure the transition step fits tightly against the very end of the shaft and there is no gap. This will allow for 2” of insertion depth.
  4. Once the epoxy has cured, cut the butt end to the desired golf club length with a friction or hack saw. NOTE: Never extend a graphite or steel shaft more than 2″ (unless it is a putter shaft). Any more may cause premature failure due to stress where the extension is made. If you need longer golf clubs (greater than 2”) it is best to re-shaft rather than risk using one of these graphite golf shaft extensions. The same goes for any commercially available steel shaft extensions.
  5. Never extend a golf club that already has been extended previously.
