Subject: Thoughts on re-using pulled graphite shafts?

I can get a good deal on like-new pulled graphite shafts. Original stock
shafts from a set of Cobras. My present set is steel Rifle shafts.
However, I've asked around and get conflicting reports on reshafting with
used graphite shafts. A couple of local club makers have said that the
graphite tips are weakened when pulled and reused. Any thoughts?

I would run, not walk away from a deal like that, not that there is
definitely anything wrong with it,
but if I did chance it, I'd want to trim back to a "solid" point, if
possible, on the shaft before using it, which might make for a too stiff
flex.
Have never been sold on the idea.

I have pulled a lot of graphite shafts. They are pretty easy to pull
from iron heads. The only time I wrecked a graphite shaft pulling it
from an iron head was the first time I ever did it.
It can be difficult to get them out of many wood head because the hosel
of many wood heads is recessed into the head and you have to heat them
from the top down, and that requires a lot of patience!
If the shaft has been overheated, the graphite fibers start to separate
and the shaft will get softer at that point. When the resin in the
matrix goes, it goes! I can spot it immediately, but you could possible
sand it down a bit, maybe apply a bit of epoxy and fool someone. The
shaft will be soft at that point though, regardless of what you do.
Maybe test the tip with a pin, especially at the point where it came
out of the hosel. It it seems soft at all, pass on it!
FWIW, my experience with cheap graphite shafts of any sort is they
aren't worth it. Good graphite iron shafts cost 20 bucks or more, good
wood shafts are at least 30 bucks. The iron shafts aren't worth it
these days because DGSL's and dynalite equivalents are 10-12 bucks a
shaft and weight the same as good graphite shafts, so why waste the
money!
Cheap steel shafts also aren't worth it either. They are too often just
the rejects from the batches of regular steel shafts! DGSLs have worked
great for me, FWIW.

It depends on how much you trust the person pulling the shafts to have
done it correctly.
Graphite shafts can be reused if they have not experienced any
overheating during the pulling process. Overheating melts the matrix in
which the graphite fibers are embedded, weakening the tip. When that
happens, well, you know what happens.
The trick to pulling is not heat, but pulling pressure, such that the
instant the epoxy bond is broken by heat, out comes the shaft. The
matrix breaks down about 300 degrees; epoxy about 250 degrees, thus the
need to get the shaft out pronto once the bond is broken. I usually
check the success of this by immediately grasping the tip of the shaft
with my fingers; if it doesn't burn, I'm OK. And FWIW, I don't have any
burn scars on my fingers. :)
A related issue is whether the shafts are taper-tip or parallel-tip, and
what the hosel of the irons is, tapered or parallel. You can't
substitute one for the other. If the shafts are parallel and the hosels
tapered, your only recourse is to bore out the hosels parallel,
something that requires a drill press and special vise to hold the clubhead.
A second related issue is whether you can produce a reasonable
swingweight with new shafts. Depending on their weight, the shafts may
produce a too-heavy or too-light feeling in the irons, so this is
something to be cognizant of.
If the purpose of doing this is to reduce vibration on mishits, you
might be better off thinking about adding an insert such as is used in
sensicore shafts. You can buy them relatively cheaply (they're just
foam rubber) and install them yourself.

Mike,
I think you could do with one of these:

Much easier to replace than the skin on your fingers ;-)

First, the original 'Cobra' graphite shafts aren't that expensive to
begin with. How old are they? A good deal would probably be 20%-25% of
what a new Aldila 'Value Series' graphite iron shaft costs.
If pulled correctly (low heat, high pressure, pulled straight off as
soon as the epoxy breaks down), they may be fine. But you have no way
of being certain unless you know the clubmaker's reputation and what
type of equipment he's using.

If the guy that pulled them knows what he's doing, reusing them can work. I've
done it plenty myself.
If he doesn't know what he's doing (as in he used too much heat), the tips can
be weakened and you can expect them to fail. I had a friend who didn't even
get a complete round out a reused graphite shaft that was pulled by a local
shop.
It's a gamble, so I wouldn't pay a whole lot for a pullout myself unless I was
the one doing the pulling. That's the only way I'd know for sure what I was
getting.
YMMV.

I'm using a GAT 75 shaft on my Yonex driver that I have pulled twice. But I use the
Golfworks graphite shaft black epoxy which melts at a lower temperature than the
regular white epoxy. Somewhat easier to pull the shafts with it.
Make sure the shafts are a weight such that they will
produce the swingweight you want. I bought a set of Precept ECS irons
with graphite shafts that the manufacturer web site claims are D0. Shafts
were about 70 grams or less, 38 inch 5 iron, with 3 gram tip weights in them.
Doesn't add up anywhere near D0 according to my estimates. But they
were very good clubs with the aldiila shafts I used.
When using a used shaft, it might help to trim about a quarter inch off the
shaft tip to make the stress point at the top of the hosel and ferrule to be at
a different spot on the shaft. But not with taper tip shafts. I always test a
used shaft at a remote spot on the end of the driving range, just to be safe.
