Design for a low Hg all night pump
Hello,
I wore the vac extender suction cup (with all the air pushed out) a few months ago; this means that there was a low Hg (no more than 0.5) acting on the penis head. This was fairly comfortable and did give good head girth gains when I wore it for a week or so.
My idea is to build on this by using a presta valve, a clear plastic pipe with one end closed and one end open, and a wide silicone sleeve to seal the cylinder. The seal point will be 1 cm from the base of the penis. A bicycle handpump can draw air out of the cylinder (when air tight) decreasing the pressure. The cylinder is much smaller than the standard pump sizes and made for length gains so 25 cm long x 6 cm internal diameter. A usb electrically heated pad can be used at the penis base (just before the cylinder) to keep the blood flowing. A wear time of around 4 hours could be possible.
It is not possible to increase the vacuum Hg after detaching the hand pump, and the penis is heated throughout the process by the heated pad. The vacuum pressure is very low (no more than 0.5 with a starting Hg of 0.1). The vacuum is applied to the entire penis minus 1 cm from the base (which is where the silicone sleeve makes the seal).
Any input on this? It could work!
