Those engines were built by me. I have been building Lego Steam engines for
about 13 years now. Most are 100% Lego parts, but a few like the small yellow
one has clear oscillating cyliders that I machined out of acrylic(plexiglas).
The red engine with the built up flywheel is double acting with a machined
cylider, piston and valve. It is VERY powerful for a lego engine (almost .75
horsepower at 600 rpm). The hit and miss style engine is one of my favorites, it
runs well and quite fast (400rpm). I have built many double acting engines,
often times I make a small paper gasket with a lego axle cross shaped hole to
help prevent leakage. Wraping the cylinder with tape or sign vinyl will stop
leakage and greatly increase power. The compressor I use is just a small 2
cylinder air brush style, not much presure, but lots of air flow. I will be
posting more pictures on my Brickshelf site soon of those and other engines.
