That is pretty friggin (Borrowed that term from Brian, thanks Brian!) amazing. I have to ask my machinist buddy if he knows more about this. It would be a fun experiment.

That is a brass ionospheric tapper/plunger. It's usually used in case of a catastrophic Vortex Tube failure. I always had one on my bicycle just to be safe. That and playing cards on my spokes.

Nope. It's only open on one end.

It comes apart at the knurled nut in the middle. Using this tool is a multi-step process - one of the steps is disassembling the tool at the knurled nut in the middle.

I love these tool questions. We are crazy creatures aren't we to make so many specialty tools. I love hearing about every one. That choke tester was told to me this past Saturday at a birthday party by a guy who I have known for all my life but hadn't seen in about 15 years. I bought my truck from him when I was 15! He has one of these tools and told me all about it when I brought up this thread.

At break time, I sometimes share this thread with the guys at work; especially the tool questions. It's fun. I have them pretty well trained now to keep an eye out for unusual tools that I can post here.

What is this tool?

I'll take a stab at this one.
I believe that it might be an AC service port tool.

The knurled knob and shaft is used to remove the shraeder valve.
One the schraeder valve has been removed, the knob in the center is used to close off the flow of freon.
Now that the flow of freon has been blocked, you can remove the upper portion and hook the guage set or recharge equipment up to the acme fitting. Back the valve back out and you now have access to the system.

When the recharge has been completed the process is repeated in reverse to re-install the schraeder valve.

Edit: I was close. After answering, I just had to check. The purpose of the tool is to remove and replace the shraeder valve without losing any refrigerant.

You got it 66
Well done.

It's an R12 service port Schrader valve replacement tool.




You have the floor.
