Help needed: stirling engine cocktail shaker

Post by Cocktail » Thu Jan 18, 2018 9:24 am

Now this could be fun!

I have no technical expertise in building stirling engine accessories, just a cool idea. I'd like to have a stirling model power an old fashioned hand crank butter churner, which would mix a cocktail.

Here are several links to videos that will explain this:
The stirling engine:

The nice thing about this model is that it has a regulator, so the engine speed can be adjusted.

The butter churner:

As far as a visual layout, I am envisioning that the two pieces would sit along side each other, with the pulleys, belts, etc. connecting them in between. Kind of like this:


The pulleys, belts, etc. may have to be on something placed in the middle, like this:


Because the butter churner uses gears, maybe there would be a gear attachment rather than a pulley that powers a gear on the churner, or maybe pulleys power the churner handle instead of a churner gear. I don’t know.

Here is a video and explanation of a DIY rotary tumbler:

The main issue, it seems to me, is to select a pulley, or combination of pulleys, that converts the high speed turning of the wheel on the sterling engine to the lower speed required to mix a drink in the butter churner.

I have two questions:
1) I this technically feasible?
2) If so, I'd like to pay one of you to build it. If you are interested in doing so, please send me a private message.

Thanks and cheers!

Hi Cocktail. From what I saw the "Stirling Engine" isn't exactly a Stirling engine, its a flame-licker engine. I like the idea, but the use of gears/pulleys/etc makes it somewhat tricky. I'm more of a magnetic coupling kind of guy. Good luck on your build!

The first motor is a flame licker, and if built to the right size would power the butter churn, or the tumbler. Forget the little Stirling, it won't do any more than drive the wee bloke with the axe. The Last motor is the one if you must buy rather than build your own.
