Golf club heads are attached to the golf shaft with epoxy glue. Epoxy is a thermosetting polymer that is a high strength adhesive. Two parts, the resin and the hardener, are mixed together to create a chemical reaction that cures the epoxy to hardness. The resin and the hardener are stored in separate containers and mixed together only when ready to use.
Types of Epoxy
The two basic types of epoxy suitable for golf club repair are quick cure and long cure. Quick cure is commonly called five minute epoxy and is generally desired only for putters and emergency fixes. Long cure epoxy is better over the life of the club for its higher shear strength.
Curing of Epoxy
Exact curing time will depend on the type of epoxy used and temperature of the surrounding area. A quick cure epoxy will generally be usable within an hour, while a long cure epoxy will be ready for use in about 20 hours. Epoxy should not be mixed or applied if the surrounding area temperature is less than 65 degrees F. A heat lamp can be used to speed cure time, however, it will result in a weak bond.
Tips to Replace Clubhead
Drill old epoxy out of the hosel of the club to be re-shafted. Abrade the tip of the shaft to be inserted with sandpaper and clean both surfaces with solvent to remove any chemicals that might interfere with the epoxy bond. Mix the epoxy components on a disposable surface and apply with a disposable tool such as a Popsicle stick. Follow epoxy manufacturer's instructions precisely.
Where to Find Epoxy
Regular two-part epoxy found in hardware stores can be used to re-shaft a golf club, but it is better to use epoxy designed specifically for golf clubs. Epoxy not formulated for the shear strength required to hold up to high impact will likely break loose. Golf club specific epoxy can be found at any club repair supply store or website.
