Machining G10, machinist opinion

Hello All,

I have a 18"x 18" x 5/8" of G10 I took to my machinist who can make 
about anything.  I could use some feed back on machining techniques to pass on.
My first one was (12" x1/2") I made myself.  Cutting this is the 
first. This one is much more massive and will have 1/2 " tungsten x 
2.3 (12) pressed in. The feedback I got earlier was to make the holes 
.001 smaller and press the tapered tungsten in. How far from the edge 
would be wise? The set screw method directly into the G10 will hold 
them in place (I hope).

This will be on a variable asrg gap maybe up to 400 bps or > than or so.

Thanks,
Jim Mora
