Right-Angle Steam Engine

Right-Angle Steam Engine

from 24.99

I call this a "right angle" steam engine because it has the piston and spool valve arranged at right angles to each other. This isn't very practical from the point of view of steam pipes, but it perfectly illustrates the way that the motion of the valve and piston are 90 degrees out of phase with each other (for an explanation of what that means, click here).

This is a high-quality model, made from laser-cut clear and colored acrylic. It will not run on actual steam or compressed air, but you can make it spin by pushing and pulling on the piston with just the right rhythm. The kit includes everything you need, even a mini-screwdriver. Assembly time is around 10-15 minutes.
