The snapping sounds may traumatize any insects whose friends or relatives have been killed by bug zappers.
Yes, No need for a spark plug but you don't want the wire to melt or short out where it is mounted. A rigid piece of clothes hanger wire could be...
If the ground wire is attached to the burner of your pizza oven, you just need a non-meltable conductor on the end of your spark plug wire....

I think I...
Here is a little info...
He didn't want to switch 480 volts.
It only bypasses when you press the switch to get it started.
This relay circuit should do it but you need a wall wart power supply or battery to operate the relay.
For those of you that haven't been inside a starter motor, when the solenoid pulls in it pushes (engages) the pinion bendix gear in to mesh with...
[ATTACH] You almost convinced me to build this but I should be doing other things and I don't think the local pool hall would approve.
I'm sure I...
Just that solenoid, mounted correctly in a cue stick would be good enough for breaking.

I got the 3 amps number from your calculations.
I think you are on the right track with the 3 amp coils.
Maybe this will help you visualize it. Start watching at 3:00 minutes....
You might get other opinions, but I don't think your coils will get very hot if they are only energized for a fraction of a second.

You might look into the specs on these 2 diesel fuel solenoids. They both go BANG when you energize them.
This one for Westerbeke generators:...
It looks a lot like this one.
A 7.5 degree, 48 steps per revolution motor may do it.
360 / 7.5 = 48 steps per revolution.
60 / 48 = 1.25
Each step is 1 1/4...
I think I remember the first stepper motors that I played with had 180 steps per rev. They were salvaged from printers. Maybe Epson?
