I'd like to take a Walthers HO structure kit (Coal Flood Loader # 933-3051), lay the pieces on a copy machine, and enter an enlargement % so it comes out in O scale dimensions (or at least close).
I'm not the sharpest pencil in the box when it comes to figuring this kind of stuff out, can anyone help me out. I need to tell my local office supply copy center to enlarge it by ........%
Any help would be appreciated.
