Re: Stirling powered toy car

HI Ian
I have tried to get 3 and 4mm in heat fused plastic belting (polyurethane I think) but with no luck in Australia.
Do you happen to know where it can be purchased, even on Ebay it is hard to find and expensive.
Maybe others are having trouble trying to find the stuff.
Regards Trev

Re: Stirling powered toy car

I also have used rubber bands to drive my water pumps on my hot air engines. I have recently found some soft rubber that is used for sealing drums etc. Comes in 4mm up to 12mm. You glue it with super glues and it doesn't let go even when going around 20mm diameter pulleys under load. Better than usi...

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

Re: Flame eater V2

Hi Thanh. Very nicely put together and works sooooo well! Loved the way you made the metho burners for the engine - You have quite a few good ideas Thanh and thank you for sharing. 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.
