Hello all, Just joined the group after my first failed attempt at a lamina flow engine, not sure why it doesn't work but hey you got to expect to fail on your...
Rob: Can't help with sources in UK as I'm in Tennessee. If your cylinder is brass try a brass piston with fairly thin skirt to minimize weight. Fit to cylinder...
Thanks Stan, that is an excellent resource. The Cylinder is made of Ali - I thought the combination of PTFE and Ali would be OK - do you know of anybody else...
Rob: Good approach. The fit of a brass piston in an aluminum cylinder would probably suffer from the difference in coefficient of expansion. Brass in brass...

Thanks very much Joe, Top resource, added to my bookmarks. Look like they also do ready made piston cylinder sets, for my old unimat 3 this could prove to be...
OK, these Laminar flow engines don't seem to work, I have excellent compression and very little friction - they look too simple to actually work. I have tried...
The author at that website said he built the successful engine in a fortnight. That design probably won't work unless you live in a country that has...

Rob: They do work as witnessed by the many that have been built and run. What are the copper rolls? Rolls of Cu foil? Get some stainless steel pot scrubbers...
OK Stan, I'll try some pot scrubber, but in your first link the chap used copper plate rolled (like mine) and still gets it going ok. As I am new to this could...
Rob: Sorry, I assumed too much. TDC = Top Dead Center BDC = Bottom Dead Center DC either T or B. The point being that the Stirling must have a little, very...
Rob: In regard to the cu foil, was it rolled with lengthwise corrugations to produce many air flow channels? Or was it rolled up and inserted into the test...

Harrie, Rob: The stainless steel pot scrubber appears to be the best option. It consists of thin narrow strands. The pad stuffed in the test tube produces...
Version 4 so far, excellent compression, very little friction anywhere - 0.03mm gap between cylinder/pistion, mirrored surface on cylinder - tried various...
Rob: Sorry to hear you are still having difficulties. 1. Try bringing the engine up to temperature slower, i.e. bring the flame up to the end of the tube while...
It seems (by observation) that there is a 90 degree "phase shift" between displacer & power pistons. I would infer from this that which way the lead/lag is...
Don: You are correct the Displacer leads the piston by approximately 90 deg. which determines the direction of rotation. The laminar engine, however does not...
Rob, Did you visit the site of Robert Sier already? At http://stirlingengines.org.uk/thermo/lamina.html there are some basic measurement wich I also used. when...
Rob: Laminar and other Stirling engine that are not designed for high pressure opperation MUST be able to 'breathe.' The piston fit can be too tight! Generally...
