I do not have a video tutorial. The process is extremely simple.Purchase some 1.5” PVC, and then cut to length. The piece I used was around 2” I believe. That takes care of the chamber.
Next you will want to modify the test plug, by simply drilling two holes on the wings of the wing nut, and then attach S hooks. Crimp down the ends, so they can’t come out. You can use a zinc ring or D ring to hook the other end of the S hooks to. Now you will be able to attach the vac cap to your weight system with a spring clip (carabiner).
I have found the vacuum to be a perfect amount of pressure with this vac cap. Much like with the twist cups.
I’m not that handy, haha, that’s why.
Would you mind if you linked all the materials here? I’d appreciate it very much. Even though you’ve listed it so clearly, I still have a kind of blurry view about it in my mind. Could you please do that?
