jackhumbertAwesome! An all brass Planck.
Next would be a carbon fiber plate. Carbon fiber plate and a milled aluminum bottom would make a light weight Planck. Or a carbon fiber top and bottom plate, that would be a really light weight Planck.
A0.CA full carbon Planck would look pretty damn amazing... I wonder if it's possible to do a CF plate though. Vacuum forming the bottom wouldn't be too difficult once you got the mold right, but the plate would have to be milled out... I'm gonna talk to a buddy of mine who works pretty extensively with it to see if it would be feasible.
