Paul,
If you run a second batch, something that would be useful is to put drill
point centers in the outside surface of the casting, so that you can lay it
flat on a drill press and drill the mounting holes.  I don't know that much
about casting and shrinkage, so I am not sure that this would work, but would
make it easier if it would work.

There are at least three different hole patterns. Yes you have to worry about
shrinkage. The trick is drill them with a small drill starting from the
flat side and drill all the way through. Use those small holes to drill the
final sizes from the bumpy side.

Here are 3 pics of the process. BTW are you getting pics on AOL now?
