Re: Yorky's Horizontal Engine

This lockdown is essential and I pray for those suffering because of the virus, all I am suffering with is the inability to get to the local stores for essential bits. Just to keep things moving I had a look round the shed and came up with green and yellow paint, and I managed to find some masking t...

Re: Old stirling with a twist

In my last reply I confessed my ignorance with regard to flux generators, a term I had not come across before. Out of curiosity I did some basic research and can now see the possibilities and why they are attractive.

I am looking forward to reading more about your thoughts and build.

Re: Yorky's Horizontal Engine

I can't find anything suitable for the firebox in the shed and can't get out due to the lockdown, so a change of plan. Started to have a look at the flywheel and made it slightly heavier. I have some bits of lead roofing flashing that is about 3/32" thick. One layer of this on the outside rim o...

Re: Yorky's Horizontal Engine

Up until now this build has been the minimum to establish if I could make the concept work, I did not want to spend a lot of effort detailing only to find that the engine did not work. I am happy to say that IT WORKS . :big smile: :big smile: :big smile: :big smile: https://youtu.be/832Kyds5GZc Now ...

Re: Better late than never.

Is this an alpha or a gamma engine ? YES well - I always get these mixed up and when I do look it up I promptly forget. :confused: The engines have one displacer cylinder and one power piston and are connected by one pipe. They are basically a "tin can" type engine the only difference is ...

Re: Yorky's Horizontal Engine

Three false starts but got there in the end and I am pleased with the result. The connecting rod to the displacer cylinder is now nice and stiff, not quite a sliding bearing - I made a couple of "wheels" out of some 3mm bearings that I had in the box. The flywheel is nice and smooth in bot...

Piston power you made of ?? wood?
Sorry to confuse you - the pistons are epoxy, only the linkages are made from Bamboo.

Re: Yorky's Horizontal Engine

My new gas supply turnedup and I managed to solder the rest of the heatsink fins. It turned into a bit of an endurance event - solder one fin and two fell off. Eventually I came up with a procedure of soldering one fin and then letting everything completely cool down, try to do it more quickly and t...

Re: Yorky's Horizontal Engine

Sadi, Thanks for the reply however I am confused by it, it maybe me that's creating the confusion. To clarify matters I am not building a Palm Engine. The title of my post is "Yorky's Horizontal Engine" and the pictures show a horizontal displacer cylinder and a horizontal power piston whi...

Re: Yorky's Horizontal Engine

Thanks for the advice it is much appreciated and its nice to know you are prepared to help. Yes - I surmised the same and put A,Band C in a straight line, and my doubts were confirmed, the linkage now snatches in both directions. I agree that the link should be stiffer, however I do not currently ha...

Re: Yorky's Horizontal Engine

Not enjoying this - it seems to be taking forever. :sad: It would have been a lot easier and quicker to use annular fins, but it would have required me to buy big bits of copper. Using this configuration I am using up lots of bits from my scrap box, any small piece of pipe will do - split it, flatte...

Re: Yorky's Horizontal Engine

Oops. Somethings gone wrong. :sad: I connected up the displacer conrod and I seem to have something out of alignment. Every thing seems OK if the flywheel turns clockwise, spin the wheel anti-clockwise and everything stops dead. :cry: I think I will leave it for the time being and try and get the ti...

Re: Yorky's Horizontal Engine

Started the fly wheel, Using a left over laminate flooring tile, cut three pieces. Glued them together again. Just as a point of reference, the flywheel is 8" (200mm) Diameter 20200423_124653.jpg Made a support from the same tile. 8mm bearing from a fidgit spinner, bearing supports from 22mm (3...
