Here is the set up in the mill for  cutting the starter
pilot how with a hole saw. The top plate is Tracy's plate
rotated roughly 90 degrees to move the starter along side
the engine on the exhaust side. We are looking at the back of
the plate here. The round thing in Tracy's starter hole is
a lathe turning used to locate the center of the starter hole with
a transfer punch. The other device to the right is the
same. It is used to locate the exact center of Tracy's plate.

The starter pilot hole is roughly 2.66 inches in diameter
so unfortunately the hole saw will not do the whole job.
ha ha ha (Sorry). Hole saws come in only 1/4 inch increments.
