Nice build. I agree it looks more interesting than the balloon approach. Of course, the challenge is finding a glass cylinder that matches the plunger to shape the epoxy.
that is a good way to prepare a temporary piston, you could also insert a U shaped hook into the epoxy mold mix before curing instead of drilling it afterwords (:
i suggest you to wet the glass tube and dust it with graphite powder, if you can also preshape the putty into a close in diameter cilinder, you can add the graphite poder on the sides, only then placing it in the glass tube and pressing it. Graphite powder is a solid lubricant, it should make it easier to remove the piston and not require sanding after cure.
Nice video again! :) With your explain maybe much better as mine! :) One thing only. The flat, hard surface is not recommended for the process. I used rubber sheet, because much easier to remove the putty piston from the glass cylinder because ther rubber could stop the putty to make a shoulder on the glass cylinder's edge. Kind regards from Hungary! BLADE
I've always questioned "Why do they keep making these engines from glass"? That is NOT practical. Why not make them from metal? Stop making toy engines, and make something we can actually use.
Why do they make these from glass? Because if you are serious, you may as well get very serios! Look at the video: The Stirling Cycle part 1 (Stirling Cryogenics) That vid takes you straight into a well optimised engine. It also takes the home builder straight into despair, as it is impossible for me using koke cans and epoxy n glass to get anything like that design or efficiency, so I feel that I'm just wasting my time, while desperately wanting to make a decent engine! Ah the burden of the home inventor! :)
Very creative, alternative and resourceful idea frend since i do not have a lathe machine in here. The most common epoxy here is devcon and mighty bond they are both two kinds of paste one is a epoxy and hardener will this kind of epoxy also work? And will it also work on a steam engine? Since i read and watch about heat engines i became interest and amaze of this machinery because we can create energy power off the grid using fire heat. Tnx my frend for the videos and ideas you share.
I want to build a real working Stirling engine, and about 12' diameter parabolic dish to direct sun to run it off of, mount the hot end inside a box with a pyrex glass face, a ceramic lined steel box, and pull a partial vacuum on it for insulation, with a copper block on the end to conduct heat, into the cylinder, and build a water jackets around the cold end, to circulate cool well water through, to keep cool as possible, maybe try hydrogen or helium also, I'm thinking a engine that would fit inside a 1meter x 1 meter box, so a fairly large small engine, possibly 4cylinders, with 90° from each other, to keep power smooth, possibly add a 20mm copper tube around the hot ends to allow hot water or steam to be pumped through, maybe hot oil, to keep it working over time, with a couple 20lb flywheels, to keep it rolling, spinning a generator, being it's in a box, I guess a small starter may be needed!
J'y ai pensé à cette pâte époxy mais au lieu d'un tube en verre je préfère un tube acier ou alu avec une tige centrale filetée qui vient traverser le piston avec un écrou et du frein filet
I remember a concept car with a ceramic engine 80s. Don't remember who built it, NIssan or Mitsubishi, but the concept never took off commercially. They claimed the engine could handle much higher temperatures than an iron or aluminum block. Those days!
It is great home brew technology! But, please, can you improve your English, it is very hard to listen! Or use text-to-speech engine, or the close captions. I like it, but the language....
I've seen the technique before but not explained as thoroughly as you do here. Thanks!

It's not very critical. If your plunger is a couple of millimetres smaller in diameter you'll get a slightly irregular top surface. Just file it flat.

Nice execution for this project. Your videos are great for everyone.
Thanks!

That's good advice Blade, thanks for visiting my vídeos!
*GREAT JOB BUDDY, THANKS* 🤗
*ALL THE LOVE FROM INDIA* 🇮🇳
Thank you for not playing music.. need a higher temperature material for longer lasting .
thanks man you show very good the detail of working piston and now i understand something more
Thanks
Still waiting. When will you show us how you made this Stirling engine with this piston you made ?
Parabéns pelo vídeo. Também ficaria ótimo se mostrasse pó de grafite à massa epoxi. Seria interessante mostrar com o cortar o vidro.
Thank you brother
Another nice one - so glad I found your feed.
Can you explain me about volume ratio between displacer cylinder and power piston
Great this design is much better
Thanks for great idea
Can you use aluminum cast with graphite lube .
The replacement idea is a good one. I was in doubt about the piston height. would it be 10mm or could it be more !?

That's.......bro that's.....Amazing how did I not get the idea before🧐
Has anyone tried this epoxy piston technique with a brass or steel cylinder? Any success?
an excellent and informative video.
Question wouldn't punching a piston out of styrofoam and than sanding it down a little be just as effective?

Why not just mix powdered Graphite into epoxy resin?
greetings. design: stirling engine ??? very good. better still adapt to solar. congratulations. success.

Best video
Thank you
Thanks
bom trabalho. inteligente
Thanks bro
At last you run the engine show how you make that Stirling engine
Brilliant.
What is the black thing
Clay
Which epoxy is that??
i like it.
great,,,,,,,,
your english is like my english...
The black object name 😱😨😰
Clay
Cool
was here
🔥🔥🔥
