Ferrule? or Club Head coming off?

    My 8-iron, 710 CB, shows a bit of wear, but the space between ferrule and the club head is becoming wider and wider. Is it my club head coming off??? or just the ferrule sliding up the shaft?

    The 6 iron on my ZB Forged is doing the same. Hoping it is just the ferrule moving.

    I've had the same thing happen before and it was just the ferrule moving up the shaft. Was able to push it back down, but it started doing the same thing again over time.

    Hey bosco j, little update, in my old club making supplies I have a Lock Tight Shaft Clamp. I put that on my 6 iron and gently tapped the ferrule back into place. Worked pretty slick. No, I did not epoxy it back!

    bosco j, and Michael JC:

    Unless you're able to detect some movement of your respective iron's club head, my suspicion would say the problem you're experiencing is limited to ferrule movement. This can happen over time as the diameter of shafts, particularly steel shafts, expand and contract with changes of temperature. Shaft diameters expand with summer heat and hot club storage conditions. Shaft diameters contract again with cooling. This expansion-contraction dynamic also occurs with other shaft materials, e.g. graphite and is unavoidable. It's a property of the shaft material.

    This expansion and contraction works over time to loosen the ferrule and is not unlike the what you experience everyday when you heat a jar to loosen a stuck cap or lid. First, your club's plastic ferrules will expand with the shaft's expansion. Epoxy adhesives employed to fix the ferrule in place on the shaft can crack and potentially "release" the ferrule from the shaft. When the club's shaft later cools and contracts, often the (now slightly enlarged) diameter of the ferrule does not contract to the same degree as the shaft itself owing to different coefficients of expansion in the materials (steel/graphite shaft vs. plastic ferrule). Now when you play the club again, the vibrations created through play can work to move the (now loosened) ferrule away from the club hosel, creating the space that you're both seeing.

    To be safe, you should test your iron head's epoxy bond to the shaft to ensure that the iron head is not loose on the shaft. Testing the epoxy bond in tension (longitudinally along the shaft axis) is preferable, especially if graphite shafts are involved. Graphite shafts risk breakage when shearing forces are applied as could happen if you attempt to clamp the head or shaft in a vice and rotate/twist the other end.

    If the iron head is loose, it needs to be removed, mating surfaces cleaned, and re-epoxied. Your local community of professional club builders can effect repairs of this kind economically. And they'll be able to install a new ferrule in the repair process.

    If the problem lies with the ferrule as I have described above, you might be able to effect the repair yourself.

    Hope this helps.

    Grab the club head and the grip and twist. If the head is loose and moving you will feel it.
