Hi everybody,
I just finished my "Thermoacoustic Mobile". You can see him run on following page of my website: http://heetgasmodelbouw.ridders.nu/Webp ... ameset.htm
There you will see why I gave this funny thing this name.
Within some days I will add full description and drawing plan to the website.
Very nice work ! Whether small diameter piece is must between heater cylinder and power piston cylinder is neccessary? What is the torque? I am wating for your plans.
