From time to time, and for whatever reason, you might need to replace a graphite shaft on a Callaway club. You always can spend the money by having it done at your local pro shop or sporting goods store, or you can save money by doing it yourself.
Remove your old shaft. If your club is an older model, it might contain a screw that helps the epoxy keep the shaft and the club head together. If it has such a screw, use a small screwdriver to unscrew it, but set it aside in a safe place because you'll want to put it back on your club. There are two ways to separate the shaft from the club head. The first is to heat the hosel, or connector, of the club head with a blow torch until the epoxy liquefies. Always wear protective glasses when using a blow torch. Then ream out residue from the hosel with a wire-drill bit. The second way is to saw off the shaft at the hosel. Then use a drill to remove the end of the shaft and any residue from the hosel.
Ready the new graphite shaft by carefully removing the coating from its tip with a putty knife. Then use a piece of sandpaper to roughen the tip so it will bond better with the club head after the epoxy is applied. If the inside of the hosel is smooth, it also should be made rough with the wire-drill bit.
Determine the correct length of the shaft and mark where you intend to cut it. Because the shaft is made of graphite, it tends to shatter when cut. To avoid that, wrap about three layers of tape where you will make the cut, then use a band saw to finish the job.
Install your new shaft by applying a liberal amount of epoxy to the inside of the hosel of the club head and the tip of the shaft. Then marry the two and twist the club head slightly to make sure the epoxy is completely covering the area. Make sure the shaft is all the way inside the hosel by tapping the butt end of it on a hard surface. Finally, replace the screw, if applicable. Let the club sit for about 24 hours to let the epoxy dry.
Put on the grip. Put double-sided tape where the grip will be placed and soak it with the solvent. Then place a small amount of the solvent inside the grip and swish it around to cover, then pour out what remains. Slide the grip onto the shaft until it is as far as it will go. Then make your final tweaks to your grip while it dries, usually in about 10 to 15 minutes.
