Hello Everyone,

My kickwheel (home built) has a stainless steel wheel head (12 inch across).
It
is circular grooved although not with any great regularity. I am wanting to
install bat pins in it that would allow me to use the bats (10 inch centers
I
think is what they are drilled at) that I can buy locally.

How can I figure where to drill the holes for the pins, so that they are
correctly positioned, so that when I put a plastic bat on them, it will not
wobble ?

Not a math wiz, at least not since the aneurysm.

Sincerely,
Bud
Tustin, CA, USA

Bud,
I once bought a metal jig for drilling holes in bats. It could also
easily be used for drilling the wheel head. I believe that I bought it
directly from Creative Industries or Aardvark Supply (not far from where you
live). Give them a ring.

To locate the center line of your wheelhead, you need to ...

1 draw a circle the exact diameter of your wheelhead on a sheet of paper
with a compass

2 open the compass up a bit so that it will draw a larger circle than the
first...the larger the better.

3 positioning the pointer OUTSIDE of the original circle draw half a circle
through the original

4 measure the distance from the rim of the original circle to the point
where the compass rotated for the second arc

5 measure this same distance on the opposite side of the circle and draw an
intersecting arc over the first arc

5 where the arcs intersect will be the center line of your circle

6 measure out from the center point along this line for the location of your
bat pin locations

7 use this drawing as a template for drilling the wheelhead, and for making
bats.

Hope this helps

Tommy

Buy a 12" bat and tape it in place, then drill your holes through the holes
in the bat.

Another way to find the rotational center of the wheel head:

1. With a sharp scribe (needle tool) lightly scribe a circle on the wheel
head with the wheel turning. Make sure the scribe is held perfectly steady,
preferably against a stick crossing above the wheel head. Then with a
straight edge, lightly scribe a straight line across the wheel head near the
center, with both ends of the line at the edge of the wheel head. Find the
center of this line between where it crosses the scribed circle to the
nearest 1/64 inch or better.

2. With an accurate protractor, or a right triangle, lightly scribe a second
line, exactly perpendicular to the first line, through the center of the
first line. The center of the second line is the rotational center of the
wheel head. The second line is also the reference line on which the
location marks are measured from the center for the bat bins.

Bud, I'm cleaning out my mailbox and just noticed this post. Haven't
been following it but I do have a suggestion.
Go and buy one of the bats that you are planning on using. Stop by your
favorite hardware store on the way home. Take the bat into the store with
you, walk up to one of the clerks and get them to sell you a drill bit that
fits the holes in the bat.
Drill both of the holes all the way through the bat. Place the bat on
the wheel head and center the bat. Clamp the centered bat onto the wheel
head with atleast three clamps.
Take your favorite drill and your new drill bit and drill through the
bat pin holes on through the wheel head. The bat is serving as your index.
Make sure that it is centered and that you firmly clamp it into place so
that it doesn't move about while you drill.
Hope this helps

You suggest drilling through the bat after clamping it to the wheel head.
As
the bat pins I'm familiar with have a larger head than shaft this wont work.
The head of the pin will drop though the wheel head. One needs to drill a
hole the size of the pins shaft though the wheel head not the size of the
pin's head. Hope this helps rather than confuses what should be a simple
task.
