Then it might be listed what the full size machine uses like (bore, stroke, rod dia) if not and there is a diagram/illustration scale it up to the size you want to make and go from there. Another option is to use a diecast static model to measure and scale but that can introduce errors sometimes and with much smaller scales sometimes the details are missing. Hope this helps...

yes i dose. i'm finding there are so many things out there that it blows the mind.
