Thanks Ian

I agree with you. Longer pillars and heavier flywheel would be great.

If and when i get this machine running maybe i build my second unit where i incorporate all these improvements. We'll see

But i'll let you know when i get this one running

Hello :) update to this again http://www.youtube.com/watch?v=jkYBffsUEyQ So it runs better again. But still no continuous operation. To get to this point I- - Increased the displacer stroke 20 mm --> 30 mm. This made a big difference. Only problem is that with longer stroke i should have a longer co...

thanks vamoose I have tried different oil grades. Too thick oil will increase friction so it is a compromise thing. Maybe i try to make one more cylinder/piston now that i have practised mAking those. Then i might do without oil I have tried electrical cooling spray. It makes no big difference. But ...

Thanks Jerry I agree that displacer travel should be a bit longer. It is now about 20 mm. The problem is that it was quite hard to find a suitable displacer and now that i have found it i cant make it shorter. Also it is quite hard to make cylinder longer which would be the other way to enable longe...

Hello again! update to this- My engine is now finished! The only problem is that it won't run :mad: I have pretty much done every improvement i can think off but no luck. I made a video today about my project: http://www.youtube.com/watch?v=mhcnrsAzlOE So now i would need help from you guys What do ...

Thanks again! So when you talked about bearings it got me thinking and i added bearings to my design! I found suitable bearings from RC car netshop quite cheap i think. I ordered 8 pcs of bearings which are of diamension 6*10*3. This cost me about 28 € total. I made the displacer cylinder and piston...

Ian S C thanks for reply! First - i know about the 90 degree offset. The model is not perfectly constructed in PRO/E so while i rotate it the offset is not allways keeping up. Don't let that bother you. So are you saying this is not going to run? or that it will not run at maximum efficiency. But an...

Hello All! my first post here I'm building my first stirling engine. gamma1.jpg It is my own design but one quite similar can be seen here http://www.youtube.com/watch?v=GomgnkMBM5E&feature=related Do you think this is a working consept? cylinders are of stainless steel, for pistons i'm planning...
