Making a pump?

No way does it bend, I think I could pump my penis till it explodes in the bottle.

I have tried pretty high pressures, And the only problem is that I get a lot of small red dots on the shaft.

Could be different types of bottles in different countries?

Hi Guys,

Sorry I haven’t replied with pic’s, I haven’t checked this link for a few weeks.

I’m still using my setup. It’s working fine with good results but my bottle has developed a weak spot and collapses when under high pressure although it still seems to work OK.

Thanks for the interest, I’ll take some pic’s this week week and post them.

Sounds good, I’m interested in seeing how you built this thing :)

I really wish I would have read this thread before I spent $150+ on a pump. Oh well, I’m not really much of a builder anyways. But the process does sound fairly simple and saving close to a $100, certainly is good. i’m also very interested in seeing some pics.


Current: 6.5"BPEL x 5"EG First Goal: 7" x 5.75" Ultimate Goal: 8" x 6" Hey Peter North has one.....why not me?

I found a decent looking Tube

It looks perfect.

I have no idea how big it is though. There are small, medium and large sizes.

They are called Hagen Gravel Vacuums for aquariums.

I am going to have to go see one of these in person.

I saw the gravel vacuums on the internet before I went out and got my tube, but I was sure I could find some sort of bottle at a cheaper price, and I did, it was only 3.99.

Hi Guys,

Well, here are the pic’s of my homemade cylinder as promised.

It’s a 0.5L mineral water bottle I brought back from Germany recently. It’s made of really thick plastic. Typical German over-engineering! It measures 7.75 inches long by 2.25 diameter.

See my instructions in my previous post how I made it. The only thing I’ve changed is the position of the non-return valve. It’s now closer to the mouth end. I think it’s better that way as you are not wasting “suck” by evacuating the tube.

My bottle is showing signs of stress now. It’s got a crease along it’s length and can collapse under pressure with a POP!

I think I’ve located a supply of 10 inch long by 2.5 inch diameter clear plastic tubes so I may be developing a new version soon.

I did the same as drew1978, so easy

MityVac Brake Bleeder kit for $35 at Sears:

Then I purchased:

Http://www.petsmart.com/global/prod…m&N=2#belowFold

They have a 10”x2” tube for 8 bucks..

The MityVac comes with adapters. It took 5 mins to assemble and it works perfectly.

Only thing I need to figure out is how to make the bottom edge of the tube not as sharp, because it hurts as the suction pulls it against your skin.

My unit blew up like a balloon.

Does anyone have any info on how long to leave it or how often to increase pressure etc?

What are others’ experience? Does pumping increase length or just girth?

Glass tubes?

Hmm.

Safety a concern at all?

The guys at www.cockpump.com make their tubes out of a polymer that ‘crazes’, the way a car windshield does, so that there is no possibility of a sharp shard colliding with an erect penis.

Something to think about?

I made a tube out of a Paint ball carrying tube app 2 1/4 x 10 long

Can be bought at most paint ball supply stores 1 for app 3 or 4 dollars some tubes are thicker than others

It is sealed ( rounded) at the top drill a hole and add a fitting automotive vacuum fitting works

To take the bottom cover off just squeeze it to loosen the glue than it comes off

Than I rounded the bottom edge by heating it up and rolling it over

That tube looks great! I might have to look around for one. :)

Surfing that site for some time I found this: http://www.petsmart.com/global/prod…D=1132341480919

What do you think? I, for one, am fascinated yet scared. I know you’re thinking what I’m thinking, is it feasible?

After further consideration I’ve deemed myself insane. But seeing how easy and affordable it is to pump… I can’t afford not to. Off to Sears and Petsmart… G’day.


2005 - BPEL 6.0"x MSEG 4.5" (BEG 4.75"/HEG 4.625")

2010 - BPEL 8.0"x MSEG 5.75" (BEG 6.5"/HEG 5.875")

Goal - BPEL 9.0"x MSEG 6.5" (BEG 6.5"/HEG 6.75")

I guess that would work, but you dont know how much pressure it would build up or anything like that, or if its even strong enough get the right pressure. Cool that your getting into pumping, just ask if you have any questions, I’ve seen some great girth gains since combining pumping and clamping :D .

I was looking into pumping more for length than for girth since my dick is almost 2 inches wide but not nearly 10 inches long I think in a cylinder that size it should get a pretty good length stretch… no?
