I've heard of someone who made a full scale motor mount out of  PCV  pipe
before making the real article from 4130.

That's good too. Actually one can make an almost workable mount out
of electrical conduit by flattening the ends with a hammer and 
drilling holes in it and bolting it together. The fatigue life would suck
however.
