I have been looking out for a 3 electrode ignition spark gap block for ages,
could not find one to buy so made my own.

This isn't something I've come across before, I'd be interested to know more about it.

When bolted to this 50's Octopus test bench -

I can test run a magneto from 0 to 6000rpm, which means I can check-

Minimum speed the mag will spark at
The advance curve
Points bounce
Wear on cam to make sure all cylinders are timed right
Spark voltage

I can also warm the mag up to make sure it still sparks when hot

The Octopus can test dynamo's, alternators and starter motors as well

Very interesting, not unlike the rig that my mag was tested on a few years back.

DM,

I write articles for several classic car club magazines and I would like to write about the test rig you have. Is it possible I could have a photo of the rig and a bit of information about?

Thank you,

RogerB

This was the unit that little Dodge's mag was tested on, you can just see one spark jumping between a pair of contacts

Roger I have a bit more work to do making up a set of leads befor it is useable, once I have that done I'll take some photo's and sort some info out.

In the meantime here is a pic of the complete set up.

What a wonderful piece of kit, looks like it should belong in a 50s sci fi film
