Some bats are actually manufactured with several
different pin spacing holes. I think ten inches is
popular because it's a nice whole number (in
US measurements anyway) which is far enough
away from the edge of a 12" wheelhead to leave
the edge strong and avoid chipping out (with brittle or
wooden bats) while taking advantage of a large
radius for stability. The closer the pins are to the
center, the more torque would be applied to them;
also, any 'wobble' would translate into a wider angle
of motion. Ten inches seems like a good compromise
standard, I'm guessing. As to who that influential
arbiter of spacing is...probably the same one that
decided 50# boxes of clay are perfect, too.

The closer to the center the Bat Pins are, the more any sloppiness of the
Bat Holes is amplified.

The farther apart they are, the more any sloppiness or wear of the Bat Hole=
s
is the least interfering.

Greg,

For me with the pins 10 in apart I can choose whether to use a bat or not
without taking the pins out.

For small objects I can lift off the wheel without deforming too much I
don't use a bat. Saves space on the drying rack and the pins don't bother
me.

If I want to switch to a large bowl I just slap a bat on and go.

But like you I have thought that small bats might be nice at times. I
think I remember someone putting bat pins closer together in a bat with
regular spaced holes. Then they could put the modified bat on the wheel as
a driver for smaller bats.

I've been wondering lately why bat pins are 10 inches apart. Is there a
good reason, or did someone long ago say, 'ah, well, lets make them 10
inches'.
Is there any good reason they can't be 8 inches or 6 inches? Of course, if
you buy bats, they are standard at 10 inches to match what the wheel
manufacturers make. If you made your own bats, why couldn't the pins be
closer together?

why indeed. I make my own bats and have non-standard bat pins. Serves my
purposes much better. I have some special made bats of aluminum with
groves machines in them for special purposes. Those aluminum bats needed
bigger pins, so I drilled the heads to accept bigger diameter screws
with much larger screw heads. Works for me.

What really helped me with my bat pin placement was to set my bat pins at
an infinite distance apart. That way they do not interfere with the bat
placement at all, and ALL pin-to-hole sloppiness is zero. Measuring the
wheel head for placing the pins is a lot easier than you might think. As
far as I know all standard wheel head diameters fall well inside the marks
for the bat pins.

This is so easy.

The exact figure is not what limits us, its a matter of leverage.. If
you make them too close together you increase the sidewise force on
the holes and the pins. If too much smaller it would tear up the
holes and loosen the bats. 10 inches is now a standard for most uses
but there are other dimensions. So it is not a universal standard.

Yes...or to re-phrase or expand further -

The closer to the center the Bat Pins are, the more the inertia of the Piec=
e
on the Bat will offer to the Bat Pin Holes meeting the Pins, for any change=
s
in acceleration...and, the more this would tend to wear or degrade the
material of the Bat, at the location of the Holes, and, with that, the wors=
e
the sloppiness would be as well, of the then poorly fitting degraded Bat Pi=
n
holes of the Bat.

As compared to the Pins being as widely spaced as possible, while still
allowing a margain at the Wheel Head's rim for safety and comfort.
