Printable plans?

[Rvjimd]

I think I want to try making a dummy crane or excavator to set on my pond/river layout. Thinking light ply and balsa wood. I would like to mount an excavator or crane on a flat top barge, but some on shore at my unloading wall would be good also.

Question. Does anyone have some outline plans in a format that I could get to scale down and print to use as a template to make parts?

Thanks
