Seeking pressure chamber recommendations

[DIVEWATCHDOCTOR]

@Kinglake,
Now that you say it could perfectly be that I bought a wheel lug nut. I only remember I took a transmitter to HD and ask for any short blind cap that would have the same thread that the transmitter and walked out with a couple of bronze "caps" like the one I showed in the pictures.

You rebuilt my titanium Stingrr from assorted parts last year for my wife for my Christmas present. You made me the happiest guy on the planet.

I wear it every day.

@Wookie,
I remember the "transplant job" that your wife wanted to be done with a SS Stinger and a titanium Spyder. Glad to hear that you are happy with the result.
