This is what a bored Engineer will do. It's missing some final details, some oiling channels need to be addressed and I want to redo my bearing calculations. I used to deal with MasterCAM to buzz my creations, but unfortunately I no longer have access to that software. I can't remember what this was. I think it was a heatsink plate for spray cooling. I also dabbled in some airfoil design. this was for a project to keep tighter laminar flow across the rear glass of roadcars. Sound theory (especially when combined with Vortex Generators). I believe my final design was a Joukovsky foil that was modified to my needs. It showed promise, but it never got past design. This one was a primitive modeling program. I really want to revisit this concept. Anyone else do any modeling, or machining, etc.? I'd like to see what you guys can do.
