I don’t think that would work manko. Vacuum cup would work by expansion for its “grip” and then placing a compressive force behind that will only cut off blood flow and increase lymph buildup. Also the compressive hanger would likely slide a little and put unneeded pressure on the rim of vacuum cup. You could try it but I’m doubtful that would work effectively.

I’ve hung up to 20 lbs with the LG but yes you would have to do a slow progression, have your taping down and be conditioned for that kind of weight.

Yeah probably. I’m trying to get vac hanging down.

Today i did 2 hrs ads at around 3 to 4 lbs just to see and ended up with blood out my urethra and a small blister that is now gone. Trying to condition to get the weight up. Also my taping is way off.

Once I am conditioned and can hang it will be a lot easier to do my protocol. I’m just sick of attachment pain to the point gains don’t matter.

I was spending way too much time before like 2 hrs with the bib. And mostly just with recirculation etc. Its a good device and might still use it for a peak weight set once all stress relaxation is out.

Maybe 30min ads 3kg
Then 1hr vac hang 6kg then
20min bib set 9kg etc.
10min cyclic stretch
10min jelq

I do something similar without 1 hour vac hang. Vacuum hanging takes slow conditioning. Start at a few pounds for 20 to 30 min and slowly work up from there. If you jump up to 2 hour sets and are not conditioned for it then you’re asking for injuries. Blisters are caused by too much weight, too much time at a given weight or improper taping techniques. You can ask tbone or check my threads to how I taped.

Also be careful going from vacuum based device to compression based device if you’re getting fluid buildup from the vacuum device. It could be an idea and have played around with both forms of hanging before. Again that boils down to conditioning. But compressing tissues with fluid buildup doesn’t work and will usually result in more fluid buildup or injury.

In meantime give 2 weeks to heal blister before further attempts at vacuum hanging. When staring back start at 2 to 3 pounds for 20 to 30 min. Slowly buildup time before slowly increasing weight. If you start to be a little more aware and even paranoid you won’t keep running into these issues. Risking injury is not worth it because of the needed breaks and pain it causes

I can probably hang 10lbs with the vac but at the higher weight the dead space forms between then tip and end of cap.

If i could get a good seal with the tip. I saw your taping and suggestions over at the vacuum hangers thread. I got to try the sponge trick.

So far Ive taped with micropore like a mummy would but still. Its not the taping. Its probably the cap. I’ve tried numerous sizes S, M, L, XL. Althought ive not tried taping like a mummy, which seems to work well tape wise, for larger than M cups. Im talking about phallosan cups and those cheap aliexpress cups. They are similar size.

I may end up just getting the LG hanger. Whats another $300. If i could just get a cap. And maybe a sleeve.

Or maybe epoxy an extension to the M cup. That way the vacuum is over more than just the glans cup. But a sleeve should do that trick just as well… a strong one.. but

I tried taping today mummy style plus wrapping the bib hanger stuff thats like rubber strap, cant remember the name, to increase the friction between the mummy job and the inside of the cap and reduce the space. But the vacuum still created the space. Not to mention i got a weird shooting pain in my tip after loading 8kg..

Anyway. Its an interesting problem.

I am thinking increasing the surface area of the distal end or head would reduce the vacuum needed to hang a certain weight. Like that guy so cleverly explained.

Therefore i think maybe using an L cup and create a massive tape job so that it is all bundled up and fits nice and tight inside the cup. Almost like a turkey leg of wraps or a baseball bat. Then put the sleeve on. And wrap over the sleeve with the therawrap, theres the name i couldnt remember, to support the cap as thise sleeves are elastic so to make it more riggig. I tried the last part already so that worked somewhat but still dead space at the tip.

Using the sponge thing or paper towel inside the cup.

The greater surface area should theoretically work. Imagining a big flat surface area vs a pencil the larger one will always hold better… but what if the pencils cup was longer? Would it be comparable? I guess not as the surface area woulf only be the tip and surrounding cone. The other areas would be off limits.

A more planetary flat shape vacuum cup would be ideal in that case. But because the head is not flat it is a problem it is more like a darn pencil.

So flatten the head as much and try to limit the horizontal tension of the tape around the glans going left to right so that perhaps the expansion is more panckakey. Then use the large cup as there is more surface area at the tip.

Is the lg hanger cup round inside or more flat than round?

I was able to more comfortably hang with a bigger cup. It is all about the surface area apparently. Also, having a flat end in the cup seems to be better than a round, as the round mimics a pencil, so all the pressure ends up focused at the tip. I got 8 to 9kg on for a few minutes and seemed to be ok and much less dead space than before.

Ideally, the tip of your head wrapped should be the same circumference as the widest part of your glans so that it is like a small cylinder.

Also, working on modifying a ceramic IR lamp which i plan to be using. Pretty excited about it. Most of my gains targeting the cord where from IR, so I am revisiting to see if there is something to it that I may have overlooked when I changed to US.

It will be a 4 walled ceramic encompassed by a cylinder of aluminum with a 1000w light thing. The 4 wall will be the shaft chamber. I will use a dimmer switch to control the temperature. It should allow for 360 degree is IR exposure to the shaft, rather than hitting it at only 220 degrees at once. So it should make things easier.

Ill post some pics of this when its done.

Also, finding some people who know about peptides, to contribute to the NKISK thread. I believe that stuff will be groundbreaking for PE if it is safe to use.

And that’s all folks for now.

The holding force of a vacuum cup is:

F=psi*A

Where:
F is force in lbs
Psi is Hg/2
A is area = r^2 * pi

My glans is 1.65 erect at widest area. If i can flatten so that it is flatest at tip and equal to widest point, its effective surface area for vacuum calculation would be (1.65/2)^2 ×3.14= 2.13 in^2

Multiply times say 7.5psi which would be 15hg

Theoretical Force that could hold would be around 16lbs.

If i want to hang 20lbs i can either increase the hg or increase the surface area.

I guess i have to modify my cup now to see what vacuum im pulling with a gauge. I dont want to pull an unnecessary amount of hg if i dont have to.

The negative pressures are high in these cups while hanging heavy loads.
I need to use +15 In HG with Penimaster attachment to starting stretch with 6kg. Sometimes it holds even if the pressure drops under 10 inHG, but usually I need to set the pressure up again.

Interesting. What would you say is the effective surface area of your glans?

Predicting at 5psi and 6kg your A would be 1.76in^2. A1.5 inch glans diameter.

I am still not sure exacly what the extent of the effective surface area for a glans would be in a vacuum cup. As it relates to tip pain. As making my glans square reduces the pain substantially. But if it were round the surface area would be higher as there would be curvature. But in a flat glans, and a flat contact points at end of cup so there is no space of course, the vacuum is spread evenly i think. Whereas round glans vacuum is spread increasingly toward the tip because the glans is not a hard sphere. So naturally the tip area would be “the most square” thus having that focus effect. Thus squaring the glans seems to be the best solution.

To reduce your hg exposure you could increase your cup size thus increasing A as long as glans is square and contact point is square.

By square i mean a flat cylinder sorry..

Lower hg means longer safer hanging times.

Also, i think allowing your glans to expand perhaps half way to its max or lets say before blisters kick in allow you you to max out on your glans surface area. So not taping so tight would permit this. But not so loosely that your going over into blister territory.

PM cup has its unique design and my glans is filling it completely, in fact expanding under vacuum it is on the verge not fitting in. Hard to say what is the effective area for force calculation. Preventing blisters I have found great tip from someone I can´t recall whom. I am cutting piece of thick microfiber cloth fitted in to bottom oft the chamber against the tip of the glans. It seems to be working and I don´t have to worry about blisters anymore. No taping or any other protection.

Against your proposal I would use chambers that size you are able to fill them completely by expanding glans. Vacuum hole then covered and the tip of the glans protected by the spongy cushion.

I think I misread it quite a bit. I am not suggesting against you proposal after all.

Filling the tube is what you are after with your approach also. 15 inHG is tolerable if handled properly, choosing biggest diameter your glans will seal would be the sizing. Extra seal inserted in to tube behind the glans. How much force you are able to resist with this kind of assembly?

Not sure yet as I am still recovering from a blister so I don’t want to push it. But the preliminary tests look like 9kg could be possible for long periods. I wish I had a huge head now though, it would make hanging easier. But clamping before taping helps. I think preconditioning for 10min in a cup or so without tape to expand the head to lets say 50% the way to a blister, and then clamp, and tape at the max glans size. While in clamp attach vacuum cup and fill it, and try to flatten your head. I put a half cut cork that shapes to the round cup, but then it is flat against my head. I put a silicone pad I cut from a sleeve between the cork and head to soften the cork to head touch so it is comfortable. Seems to going to work well, but maybe need some mods more who knows.

Actually tried my XL phallosan cup today and let my head expand for 30min prior to taping and i got the best force from the expanded surface area. Then tapped just twice and everything seems to work well now. Got up to 9kg quite comfortably for 5min and no space.

The XL since is so big has a much flatter bottom so it makes sense it would be better. And rounded at the edges for that contour to the glans.

Things are looking up for my cycle 3.

I was just so tired of bib pain. Now i can hang comfortably for the time i had to reatach bib, massage, etc. And downtime from attatchment pain. All that can be hanging time at lower weights.

The name of the game is time under tension after all.

With my IR that is going to be a pentagonal panel that fits around my cock each panel measuring 5.5cm and 10cm long while it is stretching and controlling the intensity of heat with a dimmer as the pentagon will be at center and offset from it around a satelite like dish covered in aluminum to reflect the light from a halogen bulb. The ceramic panels filter the UV light from 0 to 500 nm aparently and only IR light passes through from 500 to 2500nm in the range of medical benefits for cell proliferation and what not.

Havent come up with a name yet but its luke an oven so maybe IR oven.

And i am bringing the thermometer back for this one. Once it is done i am testing again to see how high the temps go in the oven.

What is that smell. Oh, it is skin burning :)
So you think there is too much hassle with US?

Hahaha yeah the skin usually cooks first but im hoping the oven effect with the dimmer i can regulate it and increase the inner temperature over time and get the IR benefits.

I do like US but in my cycle 3 I lost my bpfsl And hardly any bpel growth as compared to when i was using IR in cycle 1 and 2. So I dont want to leave a stone unturned essentially.

Also i can do both IR for longer period and then US for 15min or so at the end to get the benefit.

Turning some stones here. Did you skip cool down procedures completely? Also fulcrums?

I would be pointing on the cool down compartment for the lack of permanent gains here.
