I am a newbie to club building and I became interested in the first

my own game of golf. Golf, unlike any other sport, is a one on one

Forget about lofts, lies etceteras. How far do you hit each club? This will be different for each golfer. I know very few that can even hit a 3 iron. I hit a 5 iron 165, 7

Check Out this picture. Probably not your best player but it can happen with
a late loading of the shaft.

Well;
First, there is no such thing as a "standard" for lie or loft angles. It
doesn't exist. However, consider the different weights of the heads; 3 iron
about 240 grams, 5 wood about 210 grams. Lie angle difference is
insignificant, particularly so when you consider that you can bend the 3
iron
With all the talk about lie angle progression going around, I'm
amazed that not one person could provide any insight to my question
below.
Come on guys, someone take a crack at this, it cant be that hard to
figure out considering all the knowledge available on this board,
cheers,
Shay.

Does anyone have a KZ Golf Maraging Power Driver head in real good condition they would sell or trade? I have a 7.5 deg.head in real good condition used as demo I would trade. contact me by private email. [EMAIL PROTECTED]
Thanks in advance,

Thanks Dave,
This morning I dug into the Appendices in Jorgensen's book and he
calculates the energy fraction in the club head after impact at 0.531,
which indicates a velocity loss of about 30%. I was in error. That
definitely changes my thinking about what happens after impact.

Alan, let me discuss this with you off-line. I've thought about it quite a
bit, and would like to try some ideas on you.
Cheers!

Uh-ohour two math whizzes are gonna work this out off line, then confuse
the hell out of us when they come back. I've seen this beforeth
If it will make you techies any happier, I can tell you that from various
forums I have attended, dealing with this subject, they all have concluded
that at impact, the head (driver) loses about 25-30% of it's speed. Of
course you guys have to have a formula to make it work, all the high speed

That's a big help.

Yes, that's what I meant. It would have been clearer if I had just said that
it was just after impact.

Graham,

more of an effect on the direction and trajectory than I would have thought
previously.

Alan,
No, half asleep, I'm not sure about reading any small graphs correctly. :-)
So, I'm sending a couple of them for you to read.
One thing I've noticed in looking at all these graphs is that there is no

Yes, this is the sort of thing I was trying to sort
out in my own mind. Also, see the comments I made in response to Bernies post.
There have been many posts about the relationship between the speed of the swing

Yes it appears that that's what's happening. I
guess the size of the decrease in acceleration and the degree to which the shaft
straightens or bends back is what has surprised me. Overall, it appears that the
affect of the head striking the ball has quite an affect on the head first
