If your lathe is an Atlas, you could chuck a stack of washers in the
3-jaw and use the index pin in the bull gear to locate the hole
location. Mount drill on toolpost.

I want to stack many of these and drill
holes in them.

How can I get these disks to center on
the rotary index table?

Someone had this idea:

use lathe to taper 1" round stock to
a point. The point is center. Put
this in the center of the rotary
index table (it has a small indentation
at center). Drill a 1" hole in a
1/2" thick piece of steel. lay this
on top of the index table, with the
1" tapered round piece going through
the hole. The taper goes through
the clamp "ways" on the rotary index
table. The 1/2 " steel is to keep
the tapered 1" rod 90 degrees to
the table.

There must be a better way?
