Face progression on a persimmon driver

that the better players probably preferred a wood club that had some face progression
on it - especially the driver.

I used to know this. We had to learn it when Fred Flinstone and I attended PGA school. :-)
Anxious to relearn it from someone with a better memory...

I guess in the good old days of persimmon, it could be used to accurately depict the amount of bulge on the face, since offset was almost non-existent and hosel location was more or less the same on all models. Since the hosel had a variable amount of whipping onto the club head, the shaft centreline would be the obvious place to measure from.

distribution and balance of the clubhead in relation to the shaft.

First of all, the driver I posted is as good as it gets.
The shaft is in the center of the head. You will not find half the woods made this well.
Next , those who worked the ball, especially with fairway clubs, wanted not only shafts centered, but also a lot of bulge and roll. Seve was among the best, with Lee, Jack, Arnie, Gary, Ben, Sam ,and Ben. If you checked the clubs they used, NOT THE CLUBS THEY ENDORSED, YOU WOULD SEE WHAT I AM TALKING ABOUT. I have a three wood which Seve rejected( Toney made him 3) it was a four wood head with a three wood loft. He hit the famous shot at the Ryder Cup in 1983 at Palm Beach Gardens on the 18th hole 243 yards out of a bunker to 10 feet with the one he kept. The club has a lot of 4 way roll

A method of balancing the weight of the head?
I took the liberty of taking the wood Charley posted and changed it to an address
shot, I hope he does not mind. I also have posted pictures of a Tommy Armour Model 693
driver and 2 wood I have sitting around not shafted or refinished.
They both show face progression as well. I think the best way to look at the face
progression is to start at the heel of the club Charley posted and follow it to
the toe in relation to the center of the shaft (just left of the photo flash on his club).

A driver with less bulge will have MORE gear effect spin and be more "workable".
If those who worked the ball wanted a lot of bulge, that was to REDUCE the effect of gear effect spin.
For example, if a right handed player hits it way out on the toe, a wood with lots of bulge will start the ball off FURTHER RIGHT an reduce the result of the gear effect spin -- i.e., the ball would curve back to the middle (draw) -- as compared to the same shot with a wood that had less bulge which would have the gear effect spin the ball further left past middle (hook).
So a driver with less bulge will have more gear effect spin and be more "curve-able" or more "workable".

That's what I thought.
I heard Harry Busson once said he made a 3-wood set up with a face to favour Jack's fade. Any truth to this?

Bulge (aka horizontal roll) REDUCES the EFFECT of the gear effect spin of a toe hook or heel slice, making the toe shot a draw to center and the heel slice a fade to center.
The gearing aspect of the gear effect would be a shot that curves MORE - i.e., more gear effect without the bulge.
Bulge or horizontal roll is NOT the factor that creates or causes the gear effect spin, it is a factor that compensates for (i.e, reduces undesired results of) excessive gear effect spin

I agree Charley (as far as bulge goes).
I think we have to remember that face progression and bulge/roll don't necessarily go hand and hand.
I have seen plenty of hickory drivers with a lot of face progression, but little or no bulge and roll - pretty
much a flat face.
Bulge and roll is a relatively new phenomena in the long history of golf clubs.

i can't speak for PGA tour playes but i don't work the ball left and right by missing the sweet spot and using gear effect. you lose heaps of distance. so i don't. i don't see how bulge effects the workability of a club. vertical roll is great for maniluplating the height of your tee shots though. and the gear effect help adjust the spin automatially. hit low on the face it increases spin to keep the ball in the air. high on the face it takes spin off to prevent ballooning.
it's interesting what the book above says about face progression affecting trajectory. i would have though the opposite was true. more face progression would mean the contact the ball earlier in the swing for a more negative angle of attack. is there any chance of posting the text relating to that image teevons? i like learning how things work. even if they don't help me play any better :P

JRS:
Are you coming from a standpoint of modern clubs (woods) or classic/persimmon?
Also - I agree with your center of gravity point regarding gear effect - but 3 iron is a bad choice to prove it out.
Obviously COG is very close to the face of an iron rendering gear effect almost nothing in most iron clubs.

It makes sense to me intuitively (I am not an expert by any means), and I will modify your sentence to express what I think: More face progression means that the ball is set up more forward in the swing for a more positive angle of attack.

A driver with very little face progression would be a lower hitting club.
Regarding bulge and roll, the strandard was 10" for both.
While a few players experimented with more curve in either, mostly seeking additional distance, they generally returned to the standard because of lost of right-to-left or up-and-down control on their shots.
If I'm not wrong, Mr. Hogan's driver had little face progression and less bulge and roll than standard. He could flush every shot and didn't want the clubface interferring with his pure ball strikes. So, he gave up some distance to keep the ball down and to reduce shot curvature. He dialed in a fade, somewhat, by also having his driver set with an open face angle.
However, I stand to be corrected by more expert posters.
