Hello all,

I think I know what you are going to say, but just in case, here goes.

I need to make a "large run" of mounting plates - for me that means more
than five :) These will be 0.065" Al, about 6.5x11 in with four or five
sets of related holes. This sounds like a great opportunity to clamp a
stack on my mill, with one catch: several of the holes require some
counter sinking. The design is more set than it sounds. I have one
working prototype, but plan to add some hole sets on the theory that
they will end up being useful.

Would you stack, clean up the edges, drill the holes (they need to be
reasonably precise, at least relatively in the different groups), and
then separately do the counter sinking on a drill press? Next up would
to be position stops to allow me to individually re-clamp the plates to
sink each plate on the mill. The only other alterative that I see is to
make the plates separately; I enjoy milling, but have better things to
do, unless that is really the only viable choice.

Recommendations?

Thanks!

Bill
