Foot pedal

The intention of this thing is to run a DIY battery spot welder :-)

The spring is 35mm long and has an outer diameter of 11.2mm, the wire is 0.9mm

The pin is a piece of Dural girder (aircraft models), but can be anything metal, with a diameter of 8mm and a length of 56mm

If you like my creation, you can support me with a small amount here:
