Hi there
Please find attached a photo of my voith-schneider tug Fiery Cross all built from scratch including the voith units. The model is built to a scale of 1:32 and the units are driven from a gearbox with motor built onto it. The superstructure is made from tinplate, skeg is made from brass soldered onto a frame. Hull was made up using 5 layers of epoxy cloth (used for canoe and windsurfer repairs).
The rest of the fittings are manufactured in all sorts of various materials ie perspex ali plastic brass really whatever was in the workshop.
I hope it's of interest
Regards Kevin
