The control panels are brushed stainless steel, 0.9mm thick.
I had them laser cut, but could almost as easily have guillotined and chassis punched them myself.
I folded them on a manual sheet metal folder, testing the angles as compared to a CAD printout.
The vertical front face makes it very stiff there, but there was too much flex on the back edge of the long CP as I didn't make them long enough to fold that edge down as well. To stiffen I attached a piece of 20x25mm angle aluminium to the back edge which makes it very stiff.
I could be convinced to make some more if the demand is there.
Wired up all the switches last night to a 12 pin molex, very time consuming. Top view of CP's in cabinet attached.
Back to lighting:
I've already seen Edgedamage's button lighting thread and have considered it. I may stick a superbright led inside one and see how it looks, but I also like the look of the bezel mounted leds.
