I may just wait until I find an entire assembly somewhere.

Looks like you'll either be waiting for Arcadeshop to restock the 12v knocker assembly or they currently have the 30v knocker assembly and the 12v coil in-stock.

I’ve never heard of measuring a pinball coil in volts, only in resistance. They’re just enameled copper wire.

If you’re truly worried about voltage issues, use the board to run a relay and then a separate power supply.

Looks like the Spooky Pinball knockers use 23-800 coils, which are close enough to Gottlieb 5194. Don’t make your own assembly, it’s never going to work right.

Thanks pbj.
Of course I've already ordered other stuff so I will be trying not to fail with that batch first at this point.
Only difficult part I would think is getting the right distance from coil body to strike plate.

If/when I can't get the stuff on its way to behave then Spooky it is.

Now I want to look up what an Alice Cooper pin is like.

bobbyb13:
Because I was too fast at ordering parts to listen to pbj wisdom this round, here we go.
If this fails then Spooky coil it is.
This would have been really easy if arcadeshop had the 12v assembly they list in stock, but instead we get me actually trying to byoac.

And...
Parts-

Opting for the 12v style here because the power supply already puts that out so it's easy.
I wasn't sure which coil holding bracket would work so I bought two that looked ok but were slightly different, the coil and plunger too of course, and a sleeve- because I didn't know that the coil came with one already.

I hadn't noticed before Scott had pointed it out, but the coil already has a diode where it needs to be so that question was a moot point thankfully.

Issue with not being able to buy the whole thing was that I needed to make a bracket.
At least I knew what they were supposed to look like and could guess at dimensions so that I had a prayer of the thing working.

And so, bracket.

Had some 1" wide aluminum stock of various thickness lying around and I have a drawer full of hammers.

I knew it would be important to start with bends in the center of this thing and work my way out or trying to do this with a vice and hammer wouldn't work out.
Actually got the measurements close enough and with a little drilling of pilot holes for bracket screws we get...

I made the dimensions such that I could try all sorts of crap stuffed in there until I found some material that gave me the dull thud sound I think the guys who designed it really wanted (instead of the standard pinball "knock" that the production cabinet has.

As I was playing with the thing after I built it, it occurred to me that I wasn't sure how this thing really needed to be hung in the cabinet.

Oriented to have the plunger fall back on it's tail in the bracket? (plunger pointing straight up?)

How do these things sit in a real cabinet?
