Points to GN250 Electronic Ignition Conversion

Typical tensile strength of phenolic sheet... 6000-12,000 psi
I've been thinking lately that maybe she wouldn't miss that thick poly cutting board. Or maybe Wally world. I use the thin dollar store one's for all kinda stuff. 2" hole saw ?
Sandwiched between fender washers. Or maybe some bar stock.
 
Chopping boards, cheapest source of good plastic for many projects.
Approaching the local deli counter can reveal a source of larger than domestic ones, made of very good engineering plastic.
Usually available in gaudy colours, of course.
 
Hey Honey, have you seen my nice new white chopping board?

Noop!

I have come across some nice ones . But very expensive .I use the dollar store ones to make perf boards for projects , project box covers etc. I just bought some HF rotary cutters that I hope will shape these nicely. Wally World house brand cutting boards are pretty good .

Shaped like plate steel and cuts like wood. Good stuff.
 
Boy has this swerved off topic.
Has any one taken a heat gun to one and tried to shape it?
 
Thinking out loud here again-- sorry if I am off. (Not read up on things )
But it appears to be known how the Gonzo box triggering device look Jims # 157
One way forward perhaps is to get one such rotor from a Salvage somewhere or just make a simple rotor with equal weights for balance and then spin it
that rectangular part there --
in a lathe ore something looking at the Output signal on a Oscilloscope or so
The pickup is already in house so to speak if I get this right.
Again not so updated on the project so this is perhaps done already
