- The sole position at address and impact are very different due to
- the bowing out of the shaft at impact. Ideally, if you want the
- sole to lie flat at impact, you need the toe slightly raised at
- address. I forget which book I read this in, but they said a good
- check of this is that you should be able to slip a piece of paper
- underneath the toe and it should touch the sole of the club half
- way to the hosel if the address lie is correct.
-
- I will now try to demostrate how a shaft and club differs at address
- and impact in ascii (with significant exaggeration) (view from behind):
-
- At address: At impact:

- I hope you get the idea. Again, since the angle between the sole of
- the club and the shaft at the hosel is constant and shaft does bow
- outwards at impact, raising the toe slightly at address will give you
- a flat sole at impact.

- Along with your height you need to know the length of your arms to
- determine if your standard lies need adjustments. The nice thing about
- forged irons are that the steel is soft enough that they can be bent
- with a little force. There are bending vices which lock in your iron
- head and have another attachment which clamps to the hosel. With the
- aid of some measurement rulers, you simply yank on the bar attached to
- the hosel until the desired lie and loft are achieved. Most repair
- shops have such a device. I was surprised how many adjustments my
- new Hogan irons needed just to be set to standard loft and lie specs.
-
- Cast clubs like Pings and Tommy Armour 845's are a different story.
- Since the cast steel is a lot harder, you actually need a machine to
- be able to bend them. The amount you can adjust a cast club is also
- very limited because cast steel is very brittle under bending
- stress. (as opposed to forged which you can bend quite a bit).
- I have seen a cast club shatter in one of those bending machines.
- This lack of adjustability is is why Pings are available in so many
- different lies (indicated by the color codes). Since forged clubs
- can be bent alot more, you just buy the standard lie and adjust as
- necessary.
