'plankie' metalwork assistance
« on: January 16, 2017, 10:47:28 PM »
Hi guys, some help from a fellow forumite would be appreciated (at some compensation of sorts of course).

I'm developing proof-of-concept hardware for an active speaker project comprising of 11 different PCB's that connect to each other with an array of direct board-to-board mounts, ribbon cable and regular wiring. This naturally needs a secure substrate for easy testing; a full chassis is neither needed nor desired as it just gets in the way. At the end it will just be bolted into a rough pine box and shipped to Europe for further evaluation.

Details are still under development, but will be:
- qty: 2x
- 3-4mm thickness aluminium
- dimensions 400 x 500mm
- approx 40x M3 threaded holes each
- at the one edge a piece of angle iron with a cutout for an IEC socket and 4 speaker terminals is all that's required, all other connections are on the boards themselves.
- tolerances not crazy.. 0.2mm max should be OK.

Since I have no metalwork equipment I can have it submitted to a lasercutting company but the two places I enquired either did not want the business of such a basic once-off or charged an exorbitant fee for the exact same reason.

Anyone willing to help or at least point me into the right direction for this kind of work?

Best way would be to have the 500 x 400 pieces cut at a laser profiling company with necessary cutouts. Then take the pieces to a machine shop for the 40 x m3 threaded holes. I can't see you getting a cheaper option unless someone does you a favour. I run an engineering company and our small parts are done that way. If you in Durbs look up IQ Engineering, they could help with drilling and tapping.
