Designing / Engineering a Vac Hanger. Input appreciated.
I have been using various vac hangers, from many manufacturers, and would like input on making my own. The main issue I have come across, at least for me is the vacuum hanger doesnt attatch to enough of the shaft. The one I use currently(MB), attatches to more of the tip/glans. I would like to make one that is a bit longer, and im hoping this will make it so I can increase weight as well.
1. Do you think a perfectly formed “cup” that is cast to the shape of one’s penis would be optimal? The other idea, would be to cast the shape of ones penis, and than allow 1/8” to 1/4” expansion in all areas.
2. How would one reduce, the “extruding” effect that happens on the urethra opening? Each time im done with a vac-hang session, my opening is swelled outward.
3. I have read that making the “cup” larger in volume would reduce the vacuum needed in the “cup” to hold weight. This is a fact, I read in a science book. The Larger the volume, the less vacuum applied, so wouldnt it make sense to make a large “cup”? If so, this would directly go against, a “custom fitted cup”.
I will leave it at that, so I dont lose people, and than perhaps we can expand after I get some feedback.
