Does the plastic on the gears get eaten away by the friction or is there some sort of lubrication?

DrDudeNL commented on 30 Nov 2015

+Liam Prince No lubrication man, it's quite sturdy stuff so it doesn't wear out all too easy. That said, if you run these at high RPM for a sustained period of time you will have some plastic dust on your table after that :-)

Man, where was this during my childhood!?!?!?

DrDudeNL commented on 06 Aug 2015

+transaxlle It was sitting in your lego box, unbuilt ;-)

Where did you get the clear sleeved pistons from ?

DrDudeNL commented on 04 Jan 2015

I have been lucky in the sense that I started doing all of this when those clear ones were still somewhat current. You can still get them at brick link but they are getting very rare and expensive now.

I love it how it even has the boxer sound to it.

Diax1324 commented on 22 Oct 2015

+Waas You gotta put these on good wooden tables so the vibrations translate into a decent sound rather than just plastic, like he has done.

Hello. I am curious on how these pneumatic engines run. Are they self-sustained?.

Cuthbert Nibbles commented on 25 Nov 2014

+DrDudeNL that motion is one that grown men who play with Lego are all too familiar with...In all seriousness, I like the idea of the pop bottles. I would've used our good old 120 psi compressor and watched the pistons fly.

DrDudeNL commented on 25 Nov 2014

+Cuthbert Nibbles Exactemundo! For most of the engine clips I have here I use a small airbrush compressor and two soda bottles for reservoir. Total capacity is about 4 litres, and a larger engine like this one will run nicely for about a minute and a half or so on that. I would not enjoy running this on a hand pump :-)

Cuthbert Nibbles commented on 25 Nov 2014

Usually it's a big air tank, or a compressor. In the original Lego, you were given a small hand pump, but they don't provide enough pressure/volume to run anything other than a small cylinder.

Apple Works commented on 19 Nov 2014

+DrDudeNL Well, but does it sustain long enough?. It's okay, thanks for replying :) 

DrDudeNL commented on 16 Nov 2014

As in, perpetual motion? 'fraid not ;-(

was this made from a plan or did you design it yourself? I like the look of it!

Glen Linscheid commented on 29 Jul 2011

I'm thinking this has poppet valves, so it must be a single acting engine.

evilamish commented on 19 Mar 2011

I would love to put that in my boat

QuantumDevices commented on 25 Apr 2012

Well done and informative video. As a percentage, how much of a cost difference is there between double and single wall designs?

BimbaManufacturing commented on 02 May 2012

Double-wall designs typically run 25-50% more than single wall designs, depending on bore size.
