Calming the solenoid slam?

[bracketracer]

I have a 24v solenoid for my start gate. Here's a before and after video of a change I made. I used a seismometer app on my iphone to attempt to view the vibrations in the track. For a couple of the "after" releases I held the power on longer to separate the hit of the solenoid with the hit when the release handle comes back and strikes the open gate. It looks like an improvement to me, how about you?

You don't need an app for that, I can hear it with my own two ears!

If you don't mind me asking how you pulled off that trick?

That basement is going to resemble "Mission Control" soon.

Oh wait! I see the title of the video! Is it a clue?

Is it the D4D solution?

Thanks,
Joe

Yes, I was inspired by D4D!
This is what I did:
I took a memory foam earplug and cut off the end. I tried to make it as long as it was wide.

Then I rolled it between my fingers and dropped it in the bore of the solenoid. This solenoid has a solid back end.

Then I slid the plunger back in and reassembled it to the track. Done! I didn't even need to adjust the position of the solenoid.

It's a memory foam jounce bumper!

Yep!

It could hardly be a BR reply to one of my questions without at least 1 term that I have to Google.
