http://gallery.anotherpower.com/main.php/d/30133-1/DSCN3958.JPG Hi, I glued the blocks together and started to shape. The weight is heavier then I thought it would be. Adding up the cost to fabricate with a epoxy coating and considering the weight, makes it unsuitable for this project. You also mak...

Can it be turned or other wise formed into a suitable shape, and is it strong enough not to break up. Ian S C Hi, I did some test cuts with a cooping saw and it works well. It is very easy to shape but thin pieces are very brittle. I plan to use a high temp epoxy to glue the blocks together, then s...

Hi, all I can say at this time is it low cost. I can easily push my thumb nail into it. I will know more in a few days.

Grill cleaning blocks from the kitchen supply store. I think it is ceramic. It is similar to Styrofoam, light weight and i...

Wow, great results. Thanks for posting. Are you using a water jacket on the cold cylinder?

Greetings, notice the large water cooling jacket. I look forward toward your results.

http://stirlingengineforum.com/viewtopic.php?f=1&t=2000 Hi, thanks for the suggestions. Basically I am looking at differences between the working projects posted in the link above and my project and the major difference is a water jacket. Thanks again. It should be about a week before I can tes...

Hi, I am working on adding a water jacket. I am using a inner tube. http://gallery.anotherpower.com/main.php/d/30104-1/DSCN3943.JPG The idea is from other youtube projects. I also will add a weight to the flywheel to neutralize the diaphragm resistance. I am rebuilding the project and correcting all...

Found the leaks, working on sealing the system.

Hi, thanks for the correction. I tried pressurizing the system and found a leak. I was only able to increase the internal pressure to 5 PSI and I can hear the leak. Working on sealing the system. Thanks again.

Results from last modifications. I am adding a water jacket, increasing the size of the displacer, and changing the power diaphragm. It still needs more suction and less friction.

Hi, thanks for the help and the info for optimal dimensions. I will post a drawing when I get it working. I did seal the the displacer. I am working on reducing the friction and I am just experimenting with what I have on hand at this time until I find better sized materials. Thanks again. I should ...
