Pumping Balls

Hey Pumpers. I am looking for a ball pump cylinder that comes apart. I am using a big mason jar with a 3.5" diameter mouth and sometimes it takes 10 minutes to get out of it. I cannot recall what those clamshell types are called. Mr Google didn't help so I am hoping you can
Is the wait to get out of your jar a problem?
The hinged tubes....
MONSTER-TUBE - Monster Tube
 
Making my own Monster tube ball pump. 2 @ 8" diameter plexi spheres with flanges from Amazon. I just need a plexi blade in a jig saw to cut out the opening. Then some neoprene sheets to serve as a seal between the flanges and to protect the jewels

Post some pics of how you’re building it! I’m sure we’d all love to see how it’s done.

of course. here is the 1st attempt. it is not sucking in air so perhaps I need a different neoprene or gasket, Maybe the hole has some leak? maybe the wall thickness of the 1/2 sphere is too light so that the 5 points of bolting do not seal properly... oy vey

Okay, it sounds like what you're seeing might just be lymph fluid or sweat being pushed out because of the pressure from using the pump. This pressure can also stretch and temporarily dry out the skin on your scrotum. This is actually a pretty typical reaction when the skin is held under that kind of pressure for a while. However, doing it for too long could irritate the skin or even cause some minor damage. To help prevent this, be sure to use some good lubrication before you start, keep your pumping sessions within a safe time frame, and then moisturize afterwards to help your skin bounce back.

I am confused.
I am not complaining about dry skin or lymph fluid.
Was this meant for me?
