Now this could be fun! I have no technical expertise in building stirling or flame licker engine accessories, just a cool idea. I'd like to have a stirling or flame licker model power an old fashioned hand crank butter churner, which would mix a cocktail. Here is a link to a butter churner: https://www.bedbathandbeyond.com/st...qdEfxDyz7NWK-oRnzZ7iP2-QKgceZOQkaArMFEALw_wcB 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: [ame]https://www.youtube.com/watch?v=HWy1yRMDe08[/ame] The pulleys, belts, etc. may have to be on something placed in the middle, like this: [ame]https://www.youtube.com/watch?v=rIjyAdOho-U[/ame] 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. Another option may be a rotary tumbler. Here are links for a DIY rotary tumbler: [ame]https://www.youtube.com/watch?v=CxCixygly1M[/ame] http://myfavoritestripper.blogspot.com/ ... rt-ii.html 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 engine to the lower speed required to mix a drink in the butter churner. The main issues, it seems to me, are: 1) To select a pulley/gears, or combination of pulleys/gears, that converts the high speed turning of the wheel on the engine to the lower speed required to mix a drink in the butter churner. 2) To have an engine with enough power to mix the drink. I haven't bought a model yet. There are many available. I'm trying to figure out if any of them would be powerful enough. I have two questions: 1) Do you think 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!
