Thank you Thank you
Repeter - what you are describing has been discussed over the years however there seems to be no standard name but here are a few:Pumping for ED;
Short cycle pumping;
Pulse pumping;
Dynamic pumping;
Dynamic stretching;
Pump and release;
Peyronie pumping protocol;
…etc…The general consensus seems to be improved EQ, few complications (edema), and questionable increases in length and girth. One of the major complaints about this method of PE is that it involves a lot of activity (pumping, releasing, repeat… all while paying close attention to the gauge) so I think most guys quit after awhile. As already mentioned, there are pumps that make short cycle pumping more convenient and less work - Mr. Fantastic (an Italian, see his thread in the Products sub-forum), PumpToys QS-7, VacuDrive.de, and probably more…
If you are a "Do It Yourself" (DIY) type of person you can certainly build an automated pump system with parts readily available on the internet. The 3 major components you need are:
A source of 12 volt DC;
A source of vacuum (like your converted aquarium pump or a vacuum pump);
A controller (a timer, a digital pressure switch, or both).
Like you, I started with the converted aquarium pump then added a timer controlled dump valve to vent the vacuum thus producing a cycle based on time. I eventually abandoned the aquarium pump. The controller is much easier and safer and cheaper to make using low voltage (12 volts DC) instead of line voltage (120 volts AC). If I already have 12VDC then it is easy to add a 12VDC vacuum pump for less than $20. The added advantage of the 12vdc pump is that I can cycle the pump on and off as well as control the rate of the pump.
The next modification was to use a digital pressure switch to control vacuum (the pump and/or vent valve) in a similar way as the commercial automated pumps. The downside here is that digital pressure switches are expensive, delicate and a bit complex. Eventually I will add back the timer circuit so that cycles can be based on time and/or vacuum.
You can save money if you DIY your pump and it can be fun if you enjoy this type of work. However, there is certainly a lot more involved than the typical PE pumping setup of cylinder and brake bleeder pump. All the parts are readily available on eBay. Let me know if you want more specifics.
Good Luck!
Part of the attraction to this PE stuff is being resourceful and creative. I have had some modest gains, and if I don’t gain anymore, along with the experience, it has been worth it. Plus my girl friend loves the gains.
I have been hard at work looking for stuff already here are a couple of things I have came up with:
This pump is supposed to go up to -16Hg, so one would need a way to control the vacuum. The advantage to the Whisper is I can just run it wide open -4Hg.
http://www.mcme lectronics.com/ … K-I-11-/28-4741 Another 12v module. I could use just this and the whisper, but I don’t think -4Hq would be quite enough vacuum. I am waiting for a new male fitting to experiment with the vacuum from the Whisper. With my brake bleeder I have been going to -5 Hg with my cycles, but I question the accuracy of the gauge. I checked my Whisper with a more accurate gauge.
So what I am still looking for is a vacuum switch. I have one in an electric car I built awhile back. I can adjust it for low and high (brake booster). I don’t remember where I got it. I think that may be all I need, and I like you said I don’t even need a timer. Do you or anyone reading this know of such a switch?
I like DIY. It is usually a lot less expensive, and if something goes wrong, I can fix it myself. Plus I usually get to use some of the junk I have laying around. If you know of an adjustable vacuum switch that turns on low, and off high in the 1 to 12 Hg range, I think that is all I would need along with the 12 volt pump. I have a couple of 12 volt power packs laying around.
