I have been hitting my clubs with a butt weight sufficient to match the
weight of all of my clubs for over two years. That means a butt weight
around 100-g in my driver. My clubs are MOI matched and have graphite
shafts in all of them. I keep a non-weighted driver around for periodic

I sure don't disagree with Dr Tutelman. I think we're

Is 100% correct about the lie angle adjustments. I left that out of
what I posted to make things simpler. If you are really anal, do some
preliminary lie adjustments on your heads before assembly.

Bob,
First, here are some SW formulas/rules of thumb that may be of value to
you:
Grams needed to change 1 SW point Formula (varies
by the length of the club):
grams = 49.61 / (length – 14)
For example, a 37" club will need a 2g (2.16g) weight difference to
change the SW 1 point
2.16 = 49.61 /
Bob,
I think your numbers are in the right direction, but want some
reassurance on their actual values. Let's do some sanity checks on them.

I did the same thing, only I taped the shaft to the fixture.
I like your wire idea much better, easier and faster!

Hi Colin:
I didn't make myself clear enough.
I do exactly what you are saying, I make sure that the heads are properly
weighted, (7 gram progression).That will insure a very constant S/W through the
set.
Let us assume that they come out at C8
Say I have a customer that wants a D3 S/W throughout t
Hi Bob,
I have always checked and adjusted head weights before frequency matching.
This works well for me.
I can get a fair approximation by taking a head/shaft SW, then measuring it
at 1/2" longer, and if appropriate, by adding a few grams to the head.

I wonder if you were to use a sacrifice "goat" shaft of say 95 grams, then you
made a set with a 75 gram shaft, would the information gleaned from the "goat"
shaft be different at 75 grams? And if so, you would have to create a formula
that would compensate for gram weight changes?

I have seen a write-up of a person who drilled a hole
such as you are comtemplating. Using a pre-tested
club as a constant, he weighted the back end of the

The other way is to sacrifice a "goat" shaft, I
believe.
