First before anybody gets upset, I am working on MY car for the dads race. My entry last year was Han Solo frozen in carbonite, Simple and easy to machine from one side only. This year I want to do something just as if not even cooler. I have a 3d model of the delorean from back to the future but I think I need to cut all four sides of my block and am not to sure on how to hold it in place especially once one side has already been cut. Any tips or tricks you guys can share?
