Ideas for diy spark coil interrupter buzzer?

[antimony]

Hi, I am reading Carlos Benitez documentation at the moment, and I am trying to make a replica of the induction coil interrupter he uses in his patents.
I am done with winding the primary and the secondary, but i have the buzzer /vibrator left to do.
I would like to ask you guys about if you may have any ideas on how to make it myself diy, or if it would be possible to maybe repurpose some other device to complete the interrupter?

Thanks in advance. /F.

Im sorry to bother you with my problem, but i have a youtube link showing what i need to make myself, and i would appreciate some feedback.

This guy shows a couple of different size spark coils. Could the vibrator or buzzer be made magnetically or with a relay switch, something like that?
Maybe it would be possible to use a ignition coil?

Thanks in advance, /F.

Dear antimony.

What you're looking for is a Trembler/Buzz box. These were fitted to early Petrol/Gasoline engines to fire the charge via a spark plug.

I have built many of these over the years using an HT ignition coil from " Old school " lawnmower engines. Modern ones are now electronic, you need to find one that has a set of points/contact breaker fitted. I used to modify a set of Automobile points by fitting an armature from an old relay so that as the magnetic field increased it attracted the armature open breaking the circuit through the LT coil. You had a constant " Buzz " and immense sparks !!

I have linked to a video for an alternative arrangement and also attached a picture of a Ford Model " T " box.
