You've got a lot of options to look at before taking on making something yourself from scratch. Your inquiry doesn't note what type of crusher you're considering - there are as many types and sizes of crushers as there are foreign automobiles.

Size is the issue where you'll have to make your most difficult decision. Don't cut yourself short on what you figure you're going to be crushing, with whatever you get: a machine that's a little bigger than you'd think is necessary is better -- much better.

The most common machines are jaw crushers and cone crushers, followed by impactor and roll crushers. Domestic North American manufacturers of several suitable crushing machines are: Johnson Crushers International (Eugene, OR); Cedarapids, Inc. (Cedar Rapids, IA); and Telsmith, Inc. (Mequon, WI). Making the best choice of machine is predicated on defining what you intend to crush with it. There's also a tremendous used crusher market out there -- your local equipment dealers may find something suitable for you.
