I build a solenoid engine that is based on the design of The Pratical Engineer (Emiel Noorlander).
Project page: https://thepracticalengineer.com/blog/diysolenoidengine
Some dimensions
A: Plunger
Material: steel bar
Ø: 6mm
B: Crankshaft
Material: Aluminum strip
Tickness: 2mm
C: flywheel axis
Material: steel bar
Ø: 6mm
Little change in the electronic schematic
The design of the schematic by Emiel had a missing resistor between the mosfet Gate and Ground.
The Gate is like a capacitor, when it is loaded the Gate closes, if the current is not unloaded fast enough the Mosfet stays active.
Always add a resistor between the Gate and Ground.
I added that to my build, and informed Emiel about this.
SW2 = Toggle switch
SW2 = Momentum switch
D1 = Diode (min. 3A)
Q1 = Mosfet N-Channel, IRF530N
R1 = Resistor 10K
R2 = Solenoid

Result
hello i have a question where did you put the resistor can you show it on the model And can you also post a link where you bought the parts
Sorry for my late response.
I added an extra image with 2 arrows where the resistor is located.
