I have a small stock of s400’s I’d like to tip stiffer, but will need to extend them after tipping. What’s the best method anyone has to tip shafts beyond the 2in recommendation with the common modern shaft extensions. I have plenty of older shafts I can part out.
If this topic has already been answered somewhere in the forum please let me know where.
I appreciate anyone’s thoughts
Use an old steel shaft.
Slide the old shaft inside the one you want to extend till you hit the step where it butts in at the butt end, mark the step, then trim so you have a couple of inches inside, roughen it up then epoxy it in before trimming to length.
What’s the most you’ve extended a club without it breaking on you?
How long do you need the extensions to be? An alternative is buying something like this?

Not sure, ive made then 5 or 6 inches longer, they do occasionally come loose. But increase length inside the shaft if you mwke them longer.
Trouble with those is the aren’t always tight inside the shaft. Using an old shaft you just find the step where they are tight.
Appreciate the insight - I’ve only used these on one set and they fit well, so I must have got lucky with the fit. I epoxied them in as well.
I defer to and appreciate your experience (and suggest the OP do the same 
).
Did a little guide to making an extender from an old shaft.
