Pumping Question

When pumping, you are taking air out of the tube, right? Well what would happen if you pumped air into the tube?

Also is there a way to make a pump without a gravel cleaner and with a bike pump?

1. Nothing

2. Use anything you like. How about a water bottle and a squeeze bulb. Search the pumpers forum. There are a couple of your Aussie comrades with long threads about building your own.

Sorry, this wasn’t really that easy to find, but secjay put together this very detailed construction guide:

Hey Guy’s I have tried searching for threads that hold answers to my questions regarding pumping, But I just can’t seem to find them , Just a little stuff here and there.
Gprent, I have seen some post of yours in these Pump Rooms , So maybe you can help me with this.
I will quote some of your stuff from other threads.
But before I do that I will go ahead and state my concern here,
First of all I never new the Size of the tube had any thing to do with gains, I hear you all mention ”Well you should have got this size tube to help with length, And you should of got this size for girth , and this size well help with girth , But counter Length etc..
So whats the formula here.
I am completely not new to pumping but , I am new to the technical points I see you guy’s have.
If anyone could please help me understand the Principles I have mentioned regarding Pumping that would be Fantastic.

How and Why is it the right size for length Improvement?

Why would it matter what Size tube he has?
In all ,won’t pumping with any size create equal gains in both length and girth?

I guess I do not understand this.
I see from you more knowledgeable Pumpers that certain tubes Towards certain people have there Advantages towards Acquiring , Specifically Girth or Length.
I just don’t understand this though,
If some one could please break this down for me.
Thanks all.
Newbie in search of Knowledge.

You will eventually get a vagina … with testicles.

Here are the tube size issues. First if the tube is too small you obviously might not fit into it. Or you fit and find that you pack it (completely fill it) with very little pumping and then you have to go out a buy another expensive tube.

Too large a tube and there is a tendency to suck your scrotum and testicles into the tube. Now sometimes pumpers want to pump the whole package and very large tubes are available for this, but generally, around here, the focus is just on penis shaft pumping.

When the tube is the correct size, it provides enough expansion space so you have room to grow for several months in both the girth and length directions without being too large as to allow for that testicle sucking problem.

There is a theory that pumpers that want to focus on length should buy a tube that is easy for them to pack, so then, the only direction you have left to expand in is the length direction. You have to be careful when pumping this way because all of the vacuum pressure is now focused on the head and you can develop water blisters which are a bitch.

The best results are obtained when you buy the correct size cylinder that will allow for expansion in both the length and girth directions.

If you want help choosing the correct size just let me know your erect length and girth near the base. The pump manufactures have size charts, but they tend to recommend cylinders on the small size. That’s good for them, because then they can sell you 2 cylinders when you find you have to buy the next size larger.

Don’t want this for sure.

I am down with that, the focus of just penis shaft pumping.

Yea this makes sense.
So if you have a larger tube, One where you are not *packed* in there, You would grow both in girth and length?

Yea , that would be great.
Now when measuring directly at the base, Do I measure has far down the base has I can without measuring the little bit of attached scrotum?
Or does that(little bit of scrotum) need to be taken in the measurement as well to pick the best tube?

As soon as I know this info, I will get you my base stats, But my gaol for pumping would be to get something that I could pack into comfortably, for length gains.
I am trying to, in the end, gain both length and girth, but I have read up on the rubber band theory, Do you believe it is wise to work on Girth or length one at a time, to not be counter-productive and optimize you overall gains, Or do you believe you can build them both At the same time and they will not pose any threat to each other in optimal gains?

Thanks Buddy!
Peace.

Just give me a girth measurement near the base. Don’t make it so complicated. We will pick out a tube where you will get optimum girth and length gains.

Just from your measurements above it looks like you are about a 10”X1.75” cylinder. But to achieve you girth goal, you will eventually have to get a 2” diameter cylinder. If you base girth is like 5.25 or larger, just get the 10”X2” and you are done.

Gprent”

My Base girth is-5.25 and my other stats are in my signature.

When you say”10x2”

Is the 2” the width of the cylinder?

The 2” more accurately is the diameter of the cylinder.

1.75” is just right for you (you will have .25” extra room there). If you get 2”, you will get your balls sucked into the tube (hurts!).

So 1.75’ Equals 5.0 in Girth(circumference)?

How do you use the formula to this?

Girth=Circumference in PE talk.

The formulae is circumference of a cylinder is pi*diameter and has to be bigger than your base girth for obvious reasons.

1.75” diameter roughly equals 5.5” circumference.

pi is a constant and equals 3.14 (approximately).

What is pi*, and it equalling 3.14?

The formula I am looking for is say. How do you know Mathematically that 1.75” diameter roughly equals 5.5” circumference.?

What mathematics is use to find this out.

I am not the brightest in this, But it would it not hurt to learn.

Thanks.

inner circumference of a pumping tube =pi*1.75”=3.14*1.75=5.5”
