Hello fellow forum members!
I have been researching scale model steam engines and will be building an RC scale model vehicle.
I work in the solar thermal manufacturing business and have also installed full-size boilers in my past 33 years of experience, but always find myself learning new things everyday.
I have been designing a Vintage Jules Verne type of amphibious vehicle with rotating screw-type pontoons for propulsion. Each pontoon will be driven by a separate steam engine with a toothed belt pulley drive system.
This type of propulsion can move the vehicle forwards/reverse/sideways and can pivot turn on a dime.
It can drive on snow, mud, pavement and water. It maneuvers similar to a military tank over rough terrain.
I have been looking at the Saito 3DTR engines and the MACCSTEAM boilers. Any constructive advice is very much welcome.
I will try to post some images of the screw-drive systems on different types of vehicles.
Kind Regards,
Giovanni

interesting idea, Ice Challenger 6 (?) also had this type of propulsion but more as a 'back-up' means of crossing water I believe... http://www.amphibiousvehicle.net/amphi/I/icechallenger6.jpeg

Thanks for the photo!
Very nice machine. Looks like it is for glacier hopping?
I have been racking my brain trying to come up with a method of wrapping the spiral shaped 1/8"x 5/8" 304L stainless-steel tread around the 4" brass screw tube.
I was thinking that I could flame heat the 1/8" x 5/8" plate and heat it until soft enough to wrap around a 4"steel tube.
I could then slide it over the 260 brass tube that has a machined 1/16" depth x 1/8' width spiral groove from end to end of the brass tube.
I'm open to some ideas, please.
Giovanni

if you have about an hour to spare - and this video is viewable in your part of the world, you can see one actually being built out of a postal delivery van! ( the other team builds a paddle tug - well, sort of...)
