If that dont work you could try VHT paint or ceramic coating the parts .I have thought about going this route ( VHT paint or ceramic coating )but both of my engines are low temp and also run on atmospheric pressure.

Great reading thanks for the links . In theory at least it looks like you can get more power per cubic inch or liter than the internal cumbustion engine can produce for the same volume. If you could contain the pressure you could in theory get twice the power as I.C.E. . I am starting to see how com...

What was it on?

true until you get to the bigger engines then they seem to favor double acting cylinders with roll sock seals.

Nice . I also like the Ross linkage stirling you made.

If you use double acting cylinders you don't have to pressurize the crankcase just the cylinders . If you can get ahold of the book Stirling Cycle Engines by Andy Ross it touches on the subject and shows some pics of double acting 4 cylinder engines in the 140 horsepower range.

yea I am glad whispergen is up and running again. I wish Andy was still selling his stirling engine kits. The model airplane motor he built was pretty cool you can see it in action on youtube by aross345 this is Andy Ross's channel. I also have an E-book that he wrote ( Makeing Stirling Engines ) an...

ah ok . I didn't know if at higher pressures it would require less heat to double the pressure. I'm sure in real life there are variables that theory cant anticipate. It's a shame there isn't more power producing stirling engines out there kinda of like a Briggs & Stratton counterpart.

I was reading in one of my stirling engine books ( stirling cycle engines by andy ross ) and if you used enough heat you could double the pressure. The question is how much heat is required to do so? Also does the same hold true for elivated pressures . would enough heat to make 14.7psi( atmospheric...

WOW that would be a problem. I know shipping costs add up fast.

thanks for the link those are some nice engines and they are alpha style to boot. I am saving up for a nice bench top lathe new or used it doesn't matter . Anything 1.250 and smaller bore size the glass syringe seems to be the most cost effective unless you are going above 500 degrees .

Well after looking for good piston and cylinder materials I think I found one of the best for the money. It is glass syringe from nttworldwide.com . The one I got was a 30 ml @ $19.95 each shipping included they have other sizes availlibel. Since I don't have a lathe yet to make my own piston and cy...

I can understand that. I guess these would be more for high power output not just demonstration purposes.

How come we dont see very many of the Siemins / Rinia Stirling engines or for that matter many double acting cylinder stirlings ?

I liked the jonbondy site. I tried the brass tubes and they work good now I have to make the rest of the engine for them .Im hoping Friday that I will get to my friends shop and put in some lathe time.
