Re: swept volume help

so when you say that i need to have ratio of 1.5 : 1between the two sides of the motor.does that mean that the power piston should be divided by the cylinder size by 1.5?? Like my engine has a Radius on 18,75mm(Half the diameter) and 111mm lenght,so that will be 3.14x18.75x111=6535,125,does that mea...

Re: My first stirling engine, I need some help!

Fantastic, the machine sound nice, i would try to adjust the displacer rod, cause it heard like it knocked hard. you dont need alot of tools to build a tin can stirling, they are easy to build, you only need some silicone, and some ballons, and small thing you have in your home.
