Author Topic: Running a spark through screws. (Read 3827 times)

I'm trying to build a detached sparking mechanism for a potato gun, and I was wondering how close I would have to put two screws to allow a spark to pass through, attached at the other end to a lightswitch and a battery.

stick`em in opposit ends if it blows up look on the bright side you have mashed potatoes

Get a grill lighter, those work well. Or just a stick lighter might work.

That's what I have in my current one; I need to make a detached sparker to test some more volatile accelerants like propane; I don't want to take my hand off if the back blows out.

Depends on the voltage really, but 3/4 of an inch should be enough for a spark to jump.

QFT, the higher the voltage the further the arc is able to travel.

depending on your fuel I would say that I good spark with 12 volts would be at about 1mm to 1.5mm apart

(IN OPEN AIR).

Keep zapping and push screw closer and closer until it finally travels through the air.

I believe they are called Amps.

Also, what is your power source?

Battery. Toggled with a regular old light switch.

I know, what kind? AAA or car battery?

They are different, you know.

Probably an 9 volt.
