i don't have my text books with me. i don't remember alloys of copper.
1" thick stock fly-cut both sides down to .980.
part size - about 1" x 1" x .980.
then i need a hole through the middle.
that's a long way to drill. the design benefits from having a smaller
size hole in there, it's for a heat sink. but a 1/8" diameter through
an inch of copper ?
i'm not sure i'd want to ask a machinist to do that. might lose parts
to drill breakage, don't want to have to deal with that.
so, what diameter would be most manufacturable ?
