*le update:
I sent my guy an email asking for a quote, here's what I sent him:
"It's me Ben again. Could you quote me a price for about 20 of the attached drawing (hatched is the plate area is the plate I need) using .063" 5052-h32 aluminum with that +/- .002" tolerance. Could you also tell me how much one plate would be, I want to test one out before buying 20 of them? Lastly, could you quote me on how much that same plate would be in stainless steel with the same thickness (near .060" thick)/tolerances?"
I'll upload the plate DWG when I get home, I don't like uploading stuff in the schools CAD lab
