I need some suggestions on what to use as my displacer that is lighter than a tin can and about that size. A soda can is too small and I dont really want to use steel wool. stirling2.JPG This will be my second stirling build. I have the pressure vessel about done. I had planned on using a tin can to...

You have some awesome engines on your youtube channel! The two can engine on your front page I noticed that the diaphragms (that's the drive piston right?) are coming out of what looks like the middle of your can. Can you put those anywhere on the pressure vessel?

well I think I have made too many modifications to this engine. Its staring to look quite ugly with cans that have been jb welded on then cut off then other cans welded on. Its time for another build. I do have a few questions though... I see a lot of displacers made of steel wool, is there more pow...

Well Jim, I think your right.. I might have to adjust my crank. It seems that when the displacer reaches its highest point on the crank that there is a lot of dead space above it. I did get it run, but I have to use a torch. Here's a link to some video of it running, maybe this can help you understa...

I don't think my displacer bushing is too loose. The way its designed there is going to to be very small pressure leaks there. As for the displacer/pressure vessel ratio with the SFA plans the displacer seems to be close to half the volume of the pressure vessel. What would be the most efficient rat...

My displacer is made out of the bottoms of two soda cans. After the JB weld set up I tested for leaks by dipping it into my hot tub. This is about the best picture I have of it.

and just so you know I took lots of pictures throughout the entire build, so if there is anything you need to see I can post pics.

When I put heat to it nothing happens.. I use about 4 tea lite candles, with ice on top. I think heat might be my problem. I think my fire box or whatever its called, is to tall. The site that I found these plans say to make the displacer out of aluminum cans making an air tight cylinder, every othe...

This is my first attempt at a stirling engine. I cant get it running and am very frustrated. I followed the plans on this site. http://astro.sfasu.edu/courses/egr112/StirlingEngine/stirling.html This is what it looked like when I first tried to get it running. stirling.JPG Then trying to get it runn...
