Should the diaphragm only swell when the displacer falls down or when its pulled up?

Thank all of you that didn't give up in my cause. The future is bright! Maybe this post will help a lot of people that can find the information listed here and use it for the incline of man!

Thank you for your help everyone!

Thanks man. I'm going to try again tomorrow using some of these figures. Hopefully things will workout!

Actually I've been thinking of using a Tin lamp oil can that has a screw top but is much like the (sweet can). I've also been swapping crank types around also seem to be ok if I can just calculate the crank throw and displacer size right. By types I've really seen two main types, the displacer in th...

I got to tell you man, that was an awesome answer! Lord knows it seems the sudo "rules of thumb" where nowhere to be found! If this was yahoo answers you would take the cake. Thank you to the bearer of knowlage.

I'm not being negitive the guy with the negativity seemed to not get my questions. I am going to just follow thru with someone else's design. It's just hard for me to figure how some of these big name stirling guys, got their designs... If they built them themselves from scratch they had to have a i...

And to junkie, your engine was the first 4 I tried to make. Using different measurements that you don't provide. Like crank placement location exacts and balloon travel in respect of crank throw. My first couple of problems where that the wire pushrods would "push and pull" too much on the...

Not in that aspect. What I mean is that these guys (Jim Larson,myfordboy) didn't just glue part together 1000 times before their respective engines worked and their plans where drawn out. There is a formula and there is logic to what I am saying whether or not you can see it. I mean come on guy, the...

It's not like that. This is a forum, if you don't want to help the cause... Just don't. Only certain intellectuals could fathom the idea of a working formula... Dude. What I'm tryin to do will help all of the stirling engine scene.

If someone will please post the plans for one of the can engine designs, I will leave this forum alone and let you guys be. I have been to the myfordboy website and the stirling builder website and there is no measurements or printable layouts of any kind. Why point people in the direction of vague ...

What do you think determines the amount of "power" obtainable? Amount of temputure change, displacer size, crank throw measure or what's your best guess?

That sound like a good idea. I will try this approach. I just don't understand why it's so hard when it should be able to work with simple ease. I mean, if it holds air, displaces air, and it at 90' crank, it should work.

I will try a shorter version. Thank you. I figured the taller the can the taller the displacer, but some part of the physics aren't working for me. I think I haven't had a good explanation of how larger the displacer should actually be in comparison to how long the crank throw should be. There reall...

I will replace the balloon cutout with inner tube. I'm just not sure that's the problem. Put it this way when I take off the balloon and blow with force into the PVC pipe, its air tight. It think it has to do with crank throw length or maybe the displacer size. I didn't know air had to travel thru t...
