This is where autocad is a great tool. Draw it and print full scale. check
paper against part.

From there, you have all your holes centers and diameters. use a center
drill or spot drill (my favorite) then drill each point. A CNC machine is
best Grin, but a DRO works too. Do your milling at the same time.

Karl,

I disagree. If he has the money for the CNC, then he should buy a
multi-spindle drilling head from those AutoDrill guys and do it in one
stroke. That way, the head manufacturer is 100% liable if the pattern comes
out wrong. A drill bushing plate could help with the oversized issue too...
But to create that plate is more work than the single part I presume he
needed.

grinning wildly at the misapplication of technology I have just suggested
