I built the Moriya fan about 10 years ago. It has never run for over 20 minutes. I have recently purchased the Moriya 2 book. I hope to improve performance of the engine. Any ideas??

Well Dave you have made a fine machine and can truly be proud of your accomplishment. Congratulations!

I made this engine last winter. I had a lot of trouble with air leaks but when I got that sorted out it took off. It would not run for long as the water boiled away quite quickly. I added a cooling tank that operates on the thermo-siphon principle.

Here is a video of the engine running. Go to you-tube and type in "Tom Jamboretz". There you will find it.

Good idea about pressurizing to find leaks. I'll try that when it stops performing. TJ

I have just finished making a Robinson hot aire engine from castings I bought from Polly Model Engineering in the UK. It was touch an go trying to get it running. Mostly from air leaks I could not find easily. It runs very nice now. Attached is a recent photo. The thermo siphon tank is 4" x 4"...

Perhaps this link would have plans that may be of help. Also IC engine plans.http://www.jerry-howell.com/Duplex.html TJ

Thanks for checking it out. TJ

The taps I need are to make the Robinson hot air engine casting kit from Polly Models in the UK. The sizes I need are BA4, BA6, BA8, and BA10. I'd be most happy if you could take a look at yours and let me know what you have and the price. Thanks TJ

Where is a good place to buy BA taps in the US?

I'm still confused. The stirling I'm looking at is near the top of the website referenced in the original post. I've printed the plans and it is definitely a stirling. We must all be confused!

Blogwitch, I just re-checked and it is a stirling. It is listed under stirling and hot air engines on the website. Have a re-look. Tom

Would anyone have the text from Live Steam magazine that had the stirling #3 engine in Elmer's engines website. It was July /August 1999. It looks interesting but I think I need more info. Thanks, TJ would anyone

I agree with Brian's method. Same thing I do. Always have success.

Make the guides first the make valve/stems to fit. Keep in pairs.
