made a little brass piece for my Olds engine ignition

[JRD77VET]

I was using a 100 year old "buzz coil" on Olds engine to provide spark to run it. I tried a small motorcycle battery and then later, a gel battery to provide power to the buzz coil. Towards the end of the day, the engine would shut off due to a drained battery. One of the guys on another forum, makes an electronic buzz coil that provides a strong spark and low drain on the battery.

contact points so there is no arching or sparking
of the points which means the points won't wear
or corrode like a conventional coil. My coils can
be triggered by the tip of a needle.

Here's Nick's electronic buzz coil

I purchased one of his coils and decided to make an adapter for the 1/4" spade connector. My spark plug wire has a "snap on" type spark plug connector on each end and I really didn't want to cut that off.

I purchased a few brass flat head screws that were 1" long and #10-32 thread. I also got brass nuts to hold the connector in place.

I made a fixture to hold the screw. 1/2" round brass , drilled and tapped #10-32 and then used a nut to hold the screw in place with 3/8" stick out.

PRO TIP-- take really small cuts or the freaking screw will bend


I turned the main diameter down to .130 ( just over 1/8" ) to fit into the crimp connector.
