David,
With my small customer numbers here in Tellico Village, I usually just install
grips manually for single clubs like drivers. If I’m doing a set of irons, I’ll
blow them on, lightly clamped in my rubber shaft holder with head against the
wall. No pressure to speak of. All my broken superlight shafts have been at the
top of the hosel.

Greetings,
One thing all of you guys need to be mindful of on the sub 50 shafts is your
clamping pressure when installing the grips.
Not just us "Pro's" who do the work, but also you consumers who are making a
purchase on one of these need to make sure your club maker is aware, because
many are not.
They are extremely thin walled and though you may not hear or feel it crack,
you may very well have created a hair line crack in the grip clamp which can
migrate up or down the shaft and cause it to break on the 1st swing or the
200th swing.
I have a pneumatic clamp with a foot pedal and I usually run about 40 psi for
steel or graphite.
If I'm doing heavy production on steel I will turn it up to about 60 psi so I
don't have to worry about slippage, but any time I have a sub 50 graphite I
turn it down to about 20 psi and ease on the foot pedal.
That's 1/2 my normal clamping pressure and applied carefully!
You want just the bare minimum pressure to not have the shaft slip.
You almost want it to slip and need to have a co worker hold the head, but not
quite.
If your rubber clamp is a bit slick because some gripping solvent has found
it's way on to it (maybe from the last time you removed a grip with a needle)
then wipe down your clamp with some acetone so it has maximum tack.
I learned this the hard way, I use a lot of the Fierce Full Force shafts which
are 49 grams, and I would say of the 1st 20 I built with my normal 40 psi about
1/2 of them broke, since I've backed off the clamping pressure I haven't had
any break except in cases of them falling off a cart or getting slammed in a
trunk or some other crazy thing that is beyond anticipation.
Of course there will always be the player that his off mats and bangs it off
the mat behind the ball, this will result in breakage just above the hosel with
any weight shaft and should not be warranted any more than wrapping it around a
tree should be.
But!! if hitting fat off mats results in breakage say in the middle of the
shaft, that got started with your clamping pressure.
If you use a vise you can just not tighten it as much, if you have one of those
clamps that are a 1/4 turn handle (either clamped or not) I'm not sure what you
would do as I don't know if those are adjustable in any way.
If they are not adjustable to lower the clamping pressure, I suppose you could
do that by clamping the shaft closer to the tip where the shaft diameter
lessens to provide a less snug fit.
Also if your ferrule is overly snug, rather than pounding it on, warm it some
first, then ease it on.

I agree, I have lost 3 stiff in the last 2 months. I have not tried the
skf lite as a replacement. what is the weight on that shaft Bernie?

Well, one thing I have learned about the UL-45 (or Integra
45)...don’t use it on a long driver for guys 6’ 4” with 100 mph+ swingspeeds. I
put a stiff on 47½” drivers for two “age 50-something” players who fell in that
size category and both did super with the club, but broke the shaft right at
the hosel top within two months. I replaced them with an SKF Lite Rev at the
same NF4 deflection numbers and, even with the bit of added weight, the results
were equally good. No problems with the Lite Revs. For lower speeds and older
seniors, the 45s work very well...I’ve had my R on a BOM and hitting it well
since they came out. Oh yeah, except for the retired lady who broke one in
about 10 swings bouncing it off a hard mat into a 1” rubber tee.
