I just went to a meeting at my local "Tinkermill".

It is open to anyone to come in and use their:
Laser cutter engraver (cuts wood up to 1/4 thick)
CNC router(s) up to 4 ft X 8 ft X 5in thick material.
CNC Mill
8X 3D Printers
workstations with SolidWorks, or Sketchup-Pro
Wood SHop
Metal shop - Mig, Tig, Pasma cutting, lathe, mill, etc
Foundry
Glass blowing shop
Robot & Electronics shop
It is open 24/7 to any member and it is only $50 a month
Needless to say, I am joining.
I think my first project will be a CF front Air Dam.
I plan on cutting an airdam positive core on the CNC router, then vacuum forming over it.
