Clifford,
I think I have those same plans in DXF format. I cant find them on my home system, must be on my work system in my office. Ooops, did I say that? I'll have to look tuesday. I knew those looked familiar. Dont remember where I got them but in dxf format they can easily be scaled. Let me take a look and see whats involved. By the way, I do mechanical and electical cad work for a living.
