Solenoid engine 2 

Beautifully made, well done

Do you have an online shop. Love that engine. It reminds me of an old lister engine.

Very Nice

Speed variation I presume is by altering the micro-switch position and thus its throw, but what makes the sound? Is it purely the mechanical sound of the switch amplified by the wooden base? Phil

bravo

what's the input voltage, rpm, and any torque?

I want this

Have you a schema ?

9 m also building this in inline 4 configuration i dont know hot to vary speed can u give me idea please ?
