I think I may, if I have enough switches. I only have the contents of one of the
new studless backhoes, minus one piston because I broke off the bottom port and
can't figure out a way to repair it. Oh, and I also have the pneumatics from the
Ultimate Builders Set. So, 11 switches, 10 (working) pistons, and a bunch of
tubing. And two small pistons from the Pitsco pneumatics bulk pack. And an air
muscle that I built a while ago, which doesn't work very well. So, I have to use
four switches per piston in the engine (8), and it seems like another four on my
compressor, because I have no oneway valves. I may start with a very tricky one
cyl engine, though I have never had much success in building a traditional one.

  One piston engines are very difficult, but don't let me stop you from trying!

Tricky? Difficult? Here are a few to get you started:

You bet!

(...) Andrew, If you call LEGO customer service, they may replace your broken piston. Well a pressure/vacuum engine will run only on pressure. The vacuum parts would be exhaust pressure to the atmosphere. I did all my testing simply using pressure, (...) (19 years ago, 23-Nov-05, to lugnet.technic)
