HO scale is 1/87 and O is 1/48
87/48 = 1,81 x 100 (to get %) = 181%.
So set the photocopier on 181% and you will get an O scale drawing.

Can anybody out there tell me the correct numbers (on a copy machine) to use when coping HO plans up to O gauge. I am going through my old Campbell kits and would like to use them on a new layout.
Thanks
