[CAUT] RE : Tuning Hammer tip sizes, was Re: huge pitch raise question

[Marcel Carey]

The thing is tuning pins don't all have the same tapered angle. Your # 3
tip might go down lower on that pin, but it doesn't mean that it's
touching the pin closer to the becket. The only way to check for fitting
is when the tip is not attached to the head. This way you can see
through where the tip is contacting the pin. Have a look, you might be
surprised. The only drawback of having a too big tip is that on softer
tuning pins where might be more twisting of the pin since your contact
point might be the top part of the pin. I personnally prefer that the
tip contacts the pin as low as possible on the tapered part.

Oh David,
As everyone knows, size isn't everything when it comes to describing
tuning lever tips. (You're basically right though. #2 could be
considered a good all-around). I don't think all tuning pins of a
particular size necessarily share the same head geometry.  My, as yet
un-upgraded default tuning hammer set up is like Michelle's...extra
short head (15 degree angle) with #3 tip.  I carry a 2"(?) head and
extra tips #2 and #4. In my roughly 30 years at this, I don't think I
would need to take off the other shoe to count the number of times I
would have used a #1 tip. 
 
I've not done my own study, nor located one that examines the congruence
of tips and tuning pins, however, I'm sure it's more than just my
experience that good tip fit can be a compromise situation, unless you
are working with one type of pin and find a tip that fits that pin.  My
sense is that, as Michelle says, the larger tip sits relatively lower on
the pin (ah like) but doesn't hang up when removing to next pin.

I would love to know what the ideal, or range of ideal relationships
between tip and pin would look like.  It seems likely that too perfect a
fit would be undesirable in that it would function like a machine taper
and be difficult to separate.   Can anyone point to existing literature
on the subject or offer their own knowledge on the subject of pin and
tip manufacture?
