  • What pressures were you running this at?

  • Don't remember for sure, but based on the performance of other, similarly built engines, probably around 40 - 50 PSI.

  • Any idea one the rpm? I've gotten my small cylinder lego engine to go up to 3400 rpm.

  • I built the engine to be more of a slow runner, but it'll go up to 3,000 easy enough.

  • what would happen if the air valve was kept open all the time instead of being opened periodically by the small wheel?

  • Another great project! I noticed a spare flywheel in the background. Do you have a source for flywheel castings? So much time is ate up machining the spokes on them.

  • It's cool, I have the macines, and the know how. Plus my dad's a machinest.

  • In actual materials, the cost isn't much. However, everything is machined using a milling machine and metal lathe. So it does require a fair investment in tools and and lot of time to do the work.

  • That's cool, How much does one of these cost? Do you have to machine them youreself?

  • No advantage from a performance perspective. I was merely trying to emulate the sound and behaviour of a 4 cycle internal combustion engine for model aesthetic reasons.
