DIY Milker Setup for Rapid Interval Pumping

DIY Milker Setup for Rapid Interval Pumping

Triggering cell-stretch receptors on the stem cells in the tunica albuginea causes them to up-regulate collagen production and most probably also to divide and multiply. That is one of the principles of penile growth. 


If you want to get into the details of the fibroblasts and myofibroblasts, and how their internal actin cytoskeleton is connected to the extracellular matrix via integrin binding sites, and the interesting cascades that are triggered by stimulating them, I have written about that elsewhere. 


Today, I will describe a little "Milker Set-Up" which can be used for rapid cycle interval pumping. 


There are three or possibly four meaningful factors we need to consider for cell-stretch receptors: 

1. How hard we stretch them. 

2. For how long we stretch them. 

3. How often we stretch them, i.e. how many times in a session. 

4. In how many directions we stretch them.


With pumping and clamping, we simultaneously cause circumferential tension and longitudinal tension of the penis, where circumferential tension will dominate for most penis shapes. 


Often, pumping is done in sets of 5-10 minutes, with a few such sets per session. That is basically between two and six "stretch events" for the stem cells, but each stretch event goes on for a long time. 


With interval pumping, shorter sets are often used. Common protocols are 20 cycles of 1 minute, or 10 cycles of 2 minutes. The Auto-Pumps sold by LeLuv and by many of the reputable vendors often have 1 minute as their shortest possible interval time. Probably to save on battery time, since it's during the pumping phase that they draw the most juice. 


I wanted more rapid intervals to give me more total stretch events per session, and this little "Milker System" is what I came up with:

The star of the show is an electric milker pump which is meant to be used for milking small farmyard animals, such as sheep and goats. You can find them on Amazon by searching for "milking machine vacuum pump". 

On its own, such a pump does not cause any pulsation or milking action. Rather, the purpose of the pump in a milking system is to hold a steady vacuum pressure. The knob simply sets the intensity of the vacuum, from 0 inHg to -24 inHg (don't use that much!). 


One VERY important thing to notice is that these vacuum pumps don't have a pressure release button. So if you were to connect it directly to your cylinder, and you were to panic, you could injure yourself. You also wouldn't get any milking action, just a steady vacuum. And if you turn the knob up, let it pump you to -15 inHg, and then turn the knob down and hope it will release the pressure... you're out of luck. Once pumped up, it has no means of releasing the vacuum. 


That is where the pump handle with a gauge and the T-connect comes into the picture. I have them from a "brake bleeder kit" from Amazon - these are super cheap to purchase. They also come with a few long lengths of hose, which come in handy. 

The pump handle is in the system only to provide a vacuum release button and a pressure gauge. You use it to release pressure at short intervals, and then the electric pump will immediately start pumping a vacuum again. 


Here is how I use it for "Milking" with rapid intervals: 

1. I start an image slide show on my computer - both as something to give me visual stimulus, and as a way to help with interval timing. I set the slide show interval to 10 seconds or so. 

2. I get erect and put on the vacuum cylinder. 

3. I hold the pump handle in one hand, and use the other hand to turn up the vacuum knob until I am at my desired working pressure. I find that with 10-15 seconds at pressure, I tolerate -15 inHg quite well, but I'm not new to pumping. If you are a beginner, start much lower and work yourself up over months. 

4. Every other image interval in my slideshow, I press the pressure release button on my pump handle and let the vacuum pressure drop close to zero. That takes just a second or two. 

5. The pump then immediately starts pumping to get back to the pressure I have set it to, and then keeps that pressure steady. 

6. I repeat this cycle for 20-30 minutes. Every other image, I release pressure, and the pump brings it back. With this cadence, The pressure is steady at -15 for about 10-12 seconds, 2 seconds are used for dropping to zero, and 6-8 seconds are spent pumping up to pressure. 


The pump is super silent, especially when I do this in bed and put a blanket and pillow over it. It is also very precise. Once the knob is set, the pump returns to the exact same pressure every cycle. smaller the volume of air in your cylinder, the more rapidly the pump will be able to return you to the set pressure. With my 2.0" cylinder it goes from zero to -15 inHg pressure in a matter of less than three seconds. With my 2.25" cylinder it takes 6-8 seconds. 


I find that with shorter intervals, I generally tolerate a higher vacuum pressure than I would with steady pressure. It feels really good, in fact. 


With silicone toe shields on the shaft, or a sleeve, I get an awesome sense of stretch with minimal edema build-up. 

10/10, would recommend. 



A more advanced use case: 

When used in conjunction with a Python clamp to do pump-assisted clamping, as I have described elsewhere, during the clamping intervals I use the pump at a very mild vacuum pressure of about -5 inHg. This subtly aids with expansion, but the cool thing is that the pump is a way of tracking your expansion. 




Well, when your penis expands from the clamping force, that expansion will fractionally decrease the negative pressure in the cylinder. The electric pump is sensitive enough to pick up on that, and activates to do a single pump or two to maintain the vacuum at the set amount. As the clamping set progresses, the subtle clicks of the pump are a measure of your continued expansion. 


Then you release pressure in the Python clamp, and turn the knob to increase the negative pressure and do a few minutes of intervals. After which you decrease the negative pressure again and do another clamping set. 



In the future, I intend to cobble together an arduino-based system with an electronic pressure release valve so I don't need to hold the pump handle in one hand and do the pressure release manually. It would be nice to have it all automated so I could set it and forget it. Stay tuned for future build posts.
