Spark plug tester from an old weedwhacker.

[Shannow]

Was harvesting scrap from some bits and pieces that I picked up from the dump (Al to melt basically), and came up with an idea for a through shaft weedwhacker.

Butchered the rod (assembled crank, and couldn't guarantee getting that right), grease packed the bearings, then can mount the rope pull end in the chuck of the drill press.

Spin her up, and the magneto fires the spark gap.

Not sure that I want a spark plug tester, but was a diversion on a miserable day, and now I've got an HV pulsed source to do SOMETHING with another day.

Pics/vids wouldn't do the ugliness justice.

That's kinda what inventing is all about. That thing might lead to something that leads to something....

Thanks Rob,
was thinking about what it might lead to, and didn't think much, until I remembered I had the drill press set for slow drilling

Fixed that...



It's nothing so strong as the coils on my V-6, but now has me wondering what I can do with IT, my $20 vacuum pump, a mason jar, and some argon !!!

If I had daughters with boyfriends I'd hook 'em up to this thing before date night and tell them it's a lie detector.
