Hi Gregg,
'Medex' ( 3/8ths thickness would be fine for even enormous Platters, but if
needing 4 feet diameter Bats, for really Heavy Pieves, the 1/2 inch thick
version could be used ) makes excellent Bats ( as is, with no treatments or
subsequent attentions needed ).
The kind with the 'White Primer' is fine, the un-Primed kind is fine, eithe=
r
way.
One can renew the Primer Surface of course, also, whenever one likes, as it
does look really nice, but will wear away with use.

'Masonite' - should be 1/4 Inch, 'Tempered' type, and smooth both
sides...and, once made into a Bat, should be 'pickled' in a Drying Oil of
some sort, such as an old fashioned mixture of Linseed Oil, Turpentine and
Japan Drier, or, any sort of traditional Drying Oil used for Wood, ought to
be fine. Any cloths or Rags contaminated with traditional Drying Oils shoul=
d
be incinerated or buried immediately, as they are known to
spontaneously combust' if left laying around.
Immerse for twenty minutes in warm, well ventilated conditions , hang by a
Wire or set in a Rack and let drip-dry for a little while, then Air dry for
a few days out of any direct Sunshine, (( ready to use at this point ) and
it will continue to 'cure' on it's own after that.
Doing this allows the Masonite Bat to offer perfect adhesion for the Clay,
while remaining stable and durable for decades of use.
Drying Oil Soaking/immersion may be repeated in a few years, for optimum
benifits.
Either of these will tend to 'dome' a little in use, which does not present
any problem for Throwing, and, actually makes 'Wiring Off' a little easier.
If set aside, and drying out, they will go back to being 'flat'.
Most any kind of Phenolic 'Board' ( in say, 3/16ths ro 1/4 Inch thickness )
material also makes excellent Bats, offers very good Clay adhesion, but, it
is somewhat expensive and difficult to obtain and somewhat more difficult t=
o
cut or work with.
Bat-Pin Holes should have a slight Bevel to their edges to reduce chipping
or wear, and to make for a faster setting on to the Pins, if Pins are going
to be used.

Gregg Lindsley asked about masonite for batts.
'
If you can't get quarter inch masonite you could laminate together
two pieces of 1/8 masonite back to back.
Dampen one bat and use Gorilla glue. Put it on a flat surface and
weight it down with a box of clay . That should make a dandy batt,

Since I got good answers as to why bat pins are 10 inches apart, and got
some good alternative spacings, I now would like some input on what
materials are good to make your own bats with. I know lots of folks make
their own. I went looking for masonite in the Sacramento area over the
weekend, without success. 1/4 inch masonite just isn't available in the few
places I looked where i thought i would find it. So, who uses what?
thanks

I had an instructor who swore by plywood. Now days plywood is pretty rough=
.
You would need to seek a good quality marine plywood with no voids.

sink cut -outs from a formica shop...large round waste from shops that do s=
ink installations...on particle board....use varnish/paint to seal the part=
icle board portions/edges...last forever. re-coat periodically.... Easy to=
drill batt pin holes too.
usually too large for a wheel head?....use a band saw... to your size.
