Steamy subject

Ya know... all this talk about steam begs me to think down a different path. Does anyone make a scale size Steam Turbine? I mean we have scale gas turbines but how about steam? Anyone? Anyone? Bueller? Bueller?...

(I couldn't begin to think how you'd even POWER the darned thing... the boiler from heck maybe?)

Sure, somewhere someone has made one, and proudly displays it at the
local engineering or steam show at the local fair ground.

Aster made one years ago, I like the Jensen design, but pricey. Wilesco makes one also, cheaper than Jensen but it is molded out of polycarbonite. I made a home made one but have dropped it since Steam engines are just more interesting to look at. I would need to do more development on mine since it was consuming a large amount of steam compaired to a piston engine to move the same boat.

The different designs were faskinatin' (as Popeye would say). Yeah, not as exciting as the reciprocating action but you could probably get some serious RPM's outta them.

I remember when Flying Models Magazine had an ad (about 1980) for a steam turbine and a reduction gear. The turbine ran at 30,000 rpm and was about $1000 IIRC. The red gear had a 10:1 ratio and sold for about $300.

Turbine don't scale well...

Steam turbines don't scale well and need quite a bit of pressure and steam volume that makes them impractical. At the size of a model the clearences have to be so close that the tolerances have to be so tight that the cost is out of sight. At small diameters there is little torque to spin the thing in the first place.

Recips still have their place...
