ooops, how do I get these pics smaller?

after months of no dealing with stirlings at all, I started another try for a rotating displacer.

I cannot go more accurate with my tools and skills, but still it does not move. I will replace the piston tonight by a condom-membrane to see if it starts breathing .... very frustating.

Any ideas?

I started with one candle, 2, 3, (it is christmas time !!!) and finally a torch.

I guess that there is too much volume in the hot area which is not diplaced when spinning. but since my tool equipment is limited to the very basic, it is hard for me to keep the clearances within milimeters

I am close to turn nuts! I just failed on my at least 10th attempt to create a rotary displacer stirling. I am using a steel box of 12 inches diameter and 3 inches hight, diplacer is half the volume, runs pretty freely in 2 ball bearings. but when I heat one side up and slowly spin the axle with the...

Hi, I do not get a piston fabricated with my little lathe that is airtight enough and has not too much friction to make a lamina flow. indeed i cannot even push the aluminum piston out of the glas test tube or a hydraulic steel pipe (probably too much leakage) even a millimeter. even though i heated...

Hi everyone, fishsmoker is a German Stirling beginner and just made my first 2 very basic stirlings run. My next project will be a lamina flow, because I cannot believe that something that simple really moves. I have entered this forum quite a bit to take a lot of ideas, so it is only fair to regist...
