Just A Light Coat Will Do It

Getting “just the right amount” of golf club epoxy on the shaft tip and coating the inside of the hosel is a delicate – and critical – part of golf club assembly.  Beginning clubmakers generally tend to use too much epoxy to start, but learn to cut back after a few messy clean-up jobs.

It is important to understand that using too much epoxy can do more harm than just creating a mess.  Remember the saying “too much of a good thing is actually a bad thing”? Over-application of epoxy can result in swingweight problems and has a tendency to break loose and causes shaft rattles over time as the club is played.  With composite assembly, the over-application of epoxy is the leading cause of shaft breakage as excess epoxy goes up inside the shaft tip to form a solid plug of epoxy.  When cured, an epoxy core extending above the top of the hosel can create a shear point within the shaft leading to premature failure – a potentially dangerous situation! Make a practice of using the proper amount of epoxy.

How much should you use?  The key is to use a LIGHT COAT.  If you use a 1/4″ dowel, mixing stick, nail, or similar object to mix the epoxy, smear the epoxy separately on the shaft tip and to the inside of the hosel. For increased speed, some clubmakers will dip a small portion of the shaft tip in the epoxy and then insert the shaft into the hosel.  In either case, insert the epoxy coated shaft slowly into the hosel with a rotating motion while going in an up and down motion to ensure complete coverage around the total circumferences of the two components.

In some cases you may hear “pop” coming from the butt end of the shaft.  Don’t be alarmed.  This is actually a good sign meaning that the air has completely escaped from the hosel due to the hydraulic pressure of the epoxy.

If you used the right amount of epoxy you should have little mess to clean up around the exterior base of the ferrule and hosel.  In addition you will ensure that excess epoxy does not work its way up inside the shaft tip (especially on composite shafts) and prevent potential breakage.

    I hear alot of crackling and poping comming from the hosel/shaft area on steel reshafted irons. Very anoying. Any quick fix? Thanks.

    Make sure the hosel is cleaned out from any old epoxy as well as removing any debris out the tip of the shaft if you are re-using the shafts.
