Re: MY FINISHED MODEL Robert Stirling's Famous Hot Ait Engine

HI Ian - I like the idea of winding copper wire around the rim and then using bog to finish it. I may very well give this a go as the alloy one is much lighter than the cast one they show. I see CB came up with another good idea of using playdough and that may even work. CB if you are reading this, ...

Re: MY FINISHED MODEL Robert Stirling's Famous Hot Ait Engine

HI Ian Thanks. I saw a picture of the one in Glasgow assuming it was the one with the water cooler. I couldn't even find a cast iron pulley and had to use an aluminium one. I think I will need to add some more weight to it so it will turn over a bit easier. I am now working on a large LTD Engine usi...

MY FINISHED MODEL Robert Stirling's Famous Hot Ait Engine

Well I finally got to make my replica (or as near to) of Robert Stirling's Model of the Hot Air Engine. I bought a copy of the book by James G.Rizzo of the two engines presented to the Glasgow & Edinburgh Universities. I didn't have money to make the turned down legs and foraged these from an ol...

Re: First Sterling Finally Running

High mhafele Damn nice engine you built - It appears you do have insulation between the hot and cold side of the engine. I think that the cooling area (assuming it is aluminium) is a little small. With that much heat the cooling fins can't get rid of the heat. You could try using a small fan next to...

Re: Flame eater V2

Thahn instead of using a crank for the flame gate would a slip ring (eccentrics) to do the same job. Saves a double crank

I have never made a flame licker engine and you have just sparked my interest and it will be put on the agenda after I ...

Re: My flame eater engine !

Absolutely Amazing Thanh. You have done a nice job on the machining work and I do love the flywheel. Was it easy to balance the flywheel after adding the spokes? Every time I try to make a spoke wheel, I end up throwing it away in frustration. I am now using aluminium pulleys as they are reasonably ...

Re: Water Pump Sterling Engine

The engine works well Thanh. I thought that I would try and put the video up on the forum, but it doesn't work due to the high KB's. The actual pump works probably a bit too fast, however, it pumps one hell of a lot of water. For a small amount of heat it works better than I predicted - Will be star...

Water Pump Sterling Engine

Have finalised my water pump Sterling Engine.
As this is my first video I have tried to put on the Forum, I just hope it works.
The piston is 38mm with a 38mm Stroke and has a lot of power with a small meths burner underneath.

Well!! That didn't work - So I have put up a picture instead.

Re: New to Stirling Engines...where to start?!

Hi Brooksbee - Nice to have you on the site. You will find it most enjoyable and challenging all at the same time. I see you do not gave much to start with, so your best bet is to build a soft drink can Sterling engine which you can download from the internet. This is how I first started many years ...

Re: Useful - According to everyone it is feasible ??

They did say that it will run on other fuels and they did mention wood pellets, which I guess would be the same as husks.
As for 20kW Thanh I have no idea how you could build one at his specifications.

Re: Useful - According to everyone it is feasible ??

Thanh you could look back at the last post of the 10kW model coming up for sale.
The 20kW is feasible, yes, but it would need to built well and be rather large. I think Ian brought this up on another post and explained all the difficulties that it would create from a backyard workshop.
