Oh, the screwstringer. That's a technology the piano world should have deserved. Top 10 on my personal "I'd fix if I had a time machine" list.
Side/side deflection doesn't observably change the pitch, so no. You really don't need to worry about it from a stability/tuning perspective. But it's a control and energy black hole for your technique.

There is a great series of articles on this topic by Dan Levitan in the Journal, but Part 3 (Appearing in Vol. 51 No.12 published 12/08) really explains this concept of "flagpoling" well.
Then of course there is the whole second part of the book "The Craft of Piano Tuning" by Dan Levitan as well which focuses on "The Tuner's Hand"

And it's making even more sense now.
Thank you, Nate.
Question, how much does pin side-to-side flagpoling affect the tuning process? Wouldn't side-to-side motion (perpendicular to the string) be negligible even at a large deflection of the pin?
Maybe Mason & Hamlin could be convinced to go back to screw stringer, just kidding.

Close.
Go back to the crescent wrench vs deep socket. If you're using that deep socket, and put force towards the string (flagpoling), it's REAL easy to have a percentage of that force go left/right instead of sharp/flat. Just push a degree or five off axis of the string, and that force gets wasted to left/right vectors.
Now switch to the crescent wrench (in line with the pinblock, almost flat). Orient it parallel to the string. Press or lift the end. 100% or your force energy goes to the flagpoling effect you're looking for.
Obviously we HAVE to be out of line with the pinblock because of the plate struts. Identify point in space on your lever where you're applying force (regardless of how you got there: high-head/low-angle, low-head/high-angle, swirly squiggle lever... doesn't matter).
Then draw a mental line between the tuning pin and that point
What's important is the angle formed by the plane of the pinblock and our mental line. The higher the angle, the less control we have during rotation (left/right force vectors are induced) and the less predictability we have during deliberate flagpoling for the same reason.

By easier flagpoling I mean the longer tip requires less force to flex pin towards string length (like your deep socket example, I don't want rotational force, I want easier pin flex force). I do this to adjust string tension without rotating the pin foot in the pinblock. A tad more uncontrollable, yes; but more useful leverage to flex the pin, yes. So, easier forward/back flagpoling (parallel to string length).
As long as the tuning tip is the same length for every pin I put it on the uncontrollable aspect of having a longer tip will remain consistent and thus predictable. Right?
That is why I'm deducing that having too short of a tip may not be a better physical use.
Thanks

No, a longer tip/head doesn't mean easier flagpoling. Not the type you use in your technique to render the string through the friction points. That would be side/side flagpoling, which doesn't really help you. It just makes the system less controllable.
Take it to the extreme to understand the system. Imagine a lever with zero lift. It's parallel with the tuning pin like a crescent wrench. All your energy goes to rotation. You can lift and push to flagpole if you like, but it's at your discretion.
Then imagine one that's just straight up, like a deep socket on the tuning pin. Rotating becomes almost impossible, but it's easy to push and bend the pin from side to side. Again, we can still push and lift to flagpole render the string, but it's uncontrollable.

So, my main reason for looking is so I can have a lighter lever...to avoid long term issues. Here is what I found:
Kestrel 6oz (top heavy?)
Faulk 8.5oz (top heavy?)
Reyburn rigid ?.?oz
Fujan 10oz (my current)
Reyburn impact 10.5oz (top heavy because impact)
Cassotto impact 12oz (can be weighted more near head)
And, now understanding that a longer tip means easier flagpoling (which I use in my technique) 40mm is what I am looking for. I also measured and the difference between a 30mm tip/15⁰ head vs 40mm tip/10⁰ head would be

One thing about tips. The tips inside that contact the tuning pins need to be sharp and durable. Dulled tips can start to compromise the squareness of the tuning pins which is not good.
And one thing about levers. If you can test drive a particular lever, do so. Tuning levers and tuning techniques should not cause pain in the hand, wrist, elbow, shoulder or upper back. Avoid problems by taking care of your body and staying in good shape physically.

The #3 tip will have more "play" before engaging with the tuning pin. It will sit deeper on a standard 2/0 pin and may or may not be noticeably faster to remove. Time you save in moving from pin to pin will probably be lost in extra lost motion prior to engaging pin. I have used the "play" in a #3 tip to bump a tuning pin trying to get a precise pin adjustment for fine pitch tuning; I have doubts about how beneficial this is/was.
Also, I can make you a rubber tuning lever ball if they are not available; contact me.

Oh,
Another question. With a #3 tuning tip does the lever come on and off the pins more quickly than #2 tip? I'm looking to have a lever specifically for pitch corrections and want the tip to slide on and off the pins quickly and easily. So does a #3 allow for quick sliding on & off or does it snug just as well as #2 but just lower onto the pins?

You make several good points, Paul.
Those blue rubber ball – ends for otherwise straight tuning levers were still available, last I checked, from Erwin's Pianoforte Supply.

I think this is misunderstood. The extra length of the tuning tip affects how much the tuning hammer flexes the tuning pin, not that the tip itself is flexing any more because it's 10 mm longer. The longer tip has more leverage against the tuning pin and flexes it more. If you have a very long tuning tip, which could be necessary on pianos with tall plate struts, you'll have to be more careful when tuning. If the tip is shorter, it won't flex the tuning pin as much. Of course you can learn to use it in either case. The shorter tip is easier to use if the head angle is 15 deg. because with a shallower angle the lever may not clear a nearby strut. If your tip is long enough, you wouldn't need any head angle at all. But I don't think they make a 0 deg. head, afaik.
As far as the tuning lever length, some prefer a longer lever because it's easier to turn tight pins. Some prefer a shorter lever because the lever is stiffer and gives better feedback when the pin turns.
I used a regular Hale hammer with a straight handle for many years, but once I discovered how ergonomic the ball-end handles were, I got a Faulk hammer. I'm not even sure what the head angle is, and I never change it. Years ago, you could buy a rubber ball that fit on the regular Hale hammer. My ball disappeared one day, and I regretted it.
Male or female threaded tips don't matter except that you might someday want to try a different brand tip that wouldn't fit the one you have.
As was mentioned, you'll find your best choice by experience. I wish I had tried different hammers earlier in my career, but I did learn to adjust to whatever I had in my hand.
It's not the destination, it's the journey. Just like tools. Some will get a tool that "everyone uses", and it won't work for them. I have a box full of these tools that I don't use, or didn't have time to modify to make them work. Coil lifters come to mind. They come too wide on the end to fit between the tuning pins. This journey of becoming a technician is full of various choices, and though you can get advice, in the end you'll find the best way and the best tools that work for you. It helps if you're a tool junkie like me. But only buy a tool when you need it, other than the essential regulating tools, and regular hand tools, screwdrivers, etc. I would not buy a retired technician's toolbox. You want to be proud of your tools. Don't buy old junky worn out tools that, like old shoes, you wouldn't want to own.
Good luck.

Subject: Tuning Lever Tip/Head Angle
I'm looking to get a new lever, not anytime soon, but still...
I've seen a lot on tuning tip lengths and tuning lever head angle with people saying "shorter tip is better" or "shorter tip is stiffer" and other readings I see "head angle isn't as important as tip length...therefore bigger head angle and shorter tip is ideal."
So, I thought I'd ask the same questions as we've all probably seen before, but to see if there's any new info:
Does a shorter tip actually noticeably flex less? 30mm Jahn tip vs 40mm Jahn tip...they are both extremely tough metal...(I have used pliers and lots of physical force to try to gouge the surface and saw no marring from the plier teeth). So if the metal is so dang resilient to marring can it really be so flexible to be able to tell a difference between 30mm and 40mm?
If it is a big difference then my best option for a new lever would be a shorter tip (30mm...my current is 40mm) and a larger head angle (15⁰ so as to clear plate struts...my current is 10⁰), correct?
Also, does it matter if the tip is male or female threaded? I currently have Jahn male tips.
Thanks
