Grafalloy features the Epic Shaft as a super light shaft with all of the vibration damping qualities of graphite. It is available for drivers, fairway & hybrid woods with .335 & .350 tip diameters in R, S & X flexes. It is also available in the same flexes for a hybrid iron with .355 & .370 tip diameters.
The nanofused nickel alloy and composite polymer substrate combine for a wall thickness of .265 inches. That is compared to a steel .335 tip wood shaft at .290" wall thickness. Therefore, it is safe to say the nanofused nickel alloy is paper-thin.
The shaft has a urethane coating that must be removed before being glued into the club head. Care must be taken during the abrading process not to remove or damage the nickel alloy with the use of sanding belts. Grafalloy's recommended procedure calls for using a 150-grit flap wheel to remove the urethane, but a non-woven graphite tip abrasive belt works great too. After removing the urethane, the nickel alloy needs to be hand-abraded with 150-grit sandpaper by making swirl marks for proper epoxy adhesion.
Follow the instructions below for both the tip preparation and trimming instructions for best results.

| Tip Preparation Procedure |
| Important Tip Prep / Assembly Instructions |
1. Use a 150 grit flap wheel to remove clear coat in the bonding area. When clear coat is removed, bright metal will appear. Stop use of flap wheel at this point.
2. Use 150 grit sand paper to apply to swirl scratches into the Nanofuse material in the bond area to ensure good mechanical lock.
3. Clean tip area with acetone and allow to air dry completely.
4. The use of 24-hour epoxy is strongly recommended.
5. Light clamp pressure should be used when gripping or analyzing frequency.
