Lego Pneumatic Engine Single Cylinder Prototype Demonstration

Simplified and hacked together prototype build for a project I've always wanted to build, which is an all clear plastic v8 version of this design. Currently waiting for parts.

Lego: Build with lego and not non-lego pieces.
Other people: How about I just ignore those rules.

Is that LEGO TECHNIC EMBODIMENT'S design?

Dude this is the most compact switchless engine I have ever seen, what type of valve did you use ?

[MTRailfan]

What kind of drill did you use for the piston

[xmysef]

Just curious, How much resistance can you feel when the piston hits the valve? Because I’m trying to make my own but I’m not sure how much it needs to be screwed down
