Stronger epoxy? Shaft twisting inside adapter.

I have 2 House of Forged shafts for my long drive driver and each has their own adapter for my x2hot head.  The first time I had the adapters installed was by a local club maker. I allowed 24hrs cure time and both shafts twisted within 10balls. Later that night I was able to pull both shafts out of the adapters by hand.  I took them down to golfsmith and we determined the first guy did not have the shafts seated all the way into the adapters. I let golfsmith do the install and everything seemed fine and he assured me they were all the way in and sturdy. Last night I had a shaft turn on me again and the other has developed a rattle. I only have about 100 hits on each shaft including one competition. Any thing specifically to look at or a stronger epoxy to suggest? I find it hard to believe this is common in the long driving community.

Weird the only time I've ever had that happen I later found the guy that assembled the club used freakin' silicone. But it twisted on the first hit.

That doesn't sound like your club maker. Did one of the check out clerks fix your club because you were in a hurry or something? :-\

No it was an ebay deal, component head. I asked if he could assemble it because he also had the shaft I needed. He offered it on his other listings so I figured why not. But he didn't do anything I asked so after the head came off I rebuilt it myself. Needless to say he got bad feedback. Crazy thing is this seller is listed as a distributor for a few well known component companies, House Of Forged being one.

I'm afraid to ask. But this "long drive community" SMURF is a part of,  What is your swing speed? 180 MPH?

LOL I had to laugh when I read it.

I laughed when I saw it, total WTF. Funny thing was they put me on their list of blocked buyers. As if I'd buy something from them again. I think they just tossed it together to get it in the mail because I was asking why I hadn't received it 3 weeks after buying it. I asked for it to be 42.5" with 10g tip weight and I paid for an Avon Chamois grip. It arrives 43" with a different grip and from the first practice swing it didn't feel right, I assume because besides the silicone not building it to my specs had it a C8. I was surprised the head didn't fly off down the fairway though it was just barely on the last 1/4" or so of bare shaft. But yeah rubbery silicone was all that was in there.

I had someone at Dick's put a steel shaft on my drivers. Three times they twisted off.

The reason was that there is a coating on the brass which needs to be taken off. Lightly sand it to remove the layer, then apply the adhesive. It's not the epoxy that is failing but the coating the epoxy is sticking to.

Not sure if you are running into the same situation, but light sanding fixed mine.

I don't know what my swing speed is with my long drive club but I'm sure it's on the low end for the sport. To be competitive at the highest level you need to be in the upper 140's. I have qualified for regionals with a drop and stop 328yd hit into the wind.

The paint on the shaft has been removed but I'm not sure if anything has been sanded inside of the adapter. I'll try to find out when I get them back.

Welp, got the two shafts fixed... I thought. One came back cross threaded so it couldn't be used and the other came back miss aligned with its puring.  Took the cross threaded one to a different Golfsmith with an extra adapter I had. Got it all fixed up and waited a week to try it. 10 balls hit with it and it twisted again. Not sure what to do at this point. There is a Golf Etc near that I might try but I'm starting to wonder if it is a smithing error or a design flaw. I wish I had just bought a Krank driver instead of this X2 Hot.

Wow, you are really having issues with the epoxy.

What is the exact size of the X2 Hot hosel? Is it a 0.335T or straight 0.335?

You said you swing somewhere between 125mph-135mph?

Do long drive drivers have larger diameter hosels? I am looking at Krank and they do look a bit more stout, but hard to tell from a picture.

As far as I have found on the net it is a straight .335 and yes, I would put my swing speed in the 130's, which we know is on the slow side for the long drive sport.  I'm not sure about the size of other long drive drivers as this is the first one I've ever owned. I think Joe Miller and Jamie Sadlowski use this X2 Hot long drive version so they must be getting something done right.

The long drive types I see don't use adjustable drivers.

Yeah, going from 4 degrees to 5 degrees in 6 steps is kind of tough.

However, I think the OP meant a shim and not an adapter.

EDIT: Bad assumption on my part. I thought he was using shims.

I've had good success with Golfsmith with standard clubs, so it surprises me that they did not use an appropriate epoxy.

Yeah, I didn't know if there is a custom 0.335 shaft or not from "House of Forged" or not. Thanks for the definitive answer.

Has nothing to do with "custom". There is no such thing as a tapered tip .335 wood shaft. It's either .350 PARALLEL or .335 PARALLEL and unless I'm mistaken, HOF doesn't make one in .350.
