PE4F High Pressure Pumping: thoughtfulgold

I’ve clamped a few days to prepare for this session. Those sessions were attempts at pumping that fell short due to orgasm but likely have only aided in ultimate efficiency. This…will be tested tomorrow before resting, as orgasm ruined a third consecutive set.

Session Notes

1. Perform 10 minutes of clamping during edging time. Perform very hard kegels to maintain a very strong erection for most of this time. Edging for 110 minutes

2. After 15 minutes break clamp for 5 minutes under IR lamp.

Other Notes

1. Expansion was exceptional, as the trend indicates.

2. A note: ZERO EDEMA for this session.
.
Pre pump unclamped was not checked
Pre pump clamped was 6.57” MSEG
Pre pump clamped #2 was 6.54” MSEG

3. I will not go into the tube erect. That is too difficult after 2 clamping sessions. The stimulation is obviously an issue when running so much clamping.

TG,

How have the gains been so far from this routine? Seems like maybe 0.15” x 0.05” ? If so, good gains for half a year. Makes me want to pump.

Those gains are roughly right. The trending upward is key here. I’ve seen a fair amount of measuring at 6.25” but not enough to claim it.

A solid 9.25” BPEL is my biggest happiness here. And when I’m back on track I may push through the end of the year to see if I can get into the 9.3” range with 6.3” as my girth prize.

I love this thread and the detailed instructions. Getting my first air pump here in a few days. Lots of experience pumping with a Bathmate, but never used an air pump before. Probably be a while before I try to construct one of these, but I may start keeping an eye out for parts. I’m getting one of the flared base LeLuv cylinders. Would that type of base work well with this type of high vac pumping? Also wondering how much longer than my BPEL I would want my tube to be. The one I got coming is 9” x 2.25”, and I’m currently a strong 6 girth at the base, 5.5 MEG, and 7 1/2” BPEL. I know it will work well for hand pumping, but wonder if the high vacuum would pull the end of my knob right up against the end of the tube.

I would learn more about how your penis likes are pumping before considering this. I air pump for years with a gauge with both a hand pump and electric pumps before venturing into this kind of deep water. Of course you know exactly what I’m talking about when I mean to be cautious and understand your physiological indicators but I’m going to reiterate it anyway.

That is the exact cylinder I’m using, that I bought for this purpose in fact. Leluv only makes flared base in regular or thick wall versions that I’m aware of at this time.

I have not experienced any drastic changes in length expansion due to high pressure pumping. When I pump by hand or with an electric pump that generates less pressure the length of expansion than the tube maybe 1/4 to 1/2 inch difference. So I don’t think you need to buy an incredibly long tube or make any special length considerations if you do switch from hand pumping to high pressure pumping.

Also, Leluv only makes cylinders in 9 and 12 inch variants that I have seen. So the question is moot. *chuckles*

Yeah, I only get about a quarter in length when I pump with my Bathmate now that I think about it. I just have read about those vacuums pulling tube-packing erections in a matter of seconds and had some nightmarish vision of my penis head being pulled right up against the vacuum tube coupling. Ouch. Yeah, I’ve been at this for a while, so I know not to go crazy. From newbie routines to the BM to IPR and most recently the Angion Method, I’ve done it all. I have a pretty good idea of how to go at this stuff. Thanks again.

I haven’t had a session to completion for about 24 days. Which I’ll count as decon, because sometimes life and my habits get in the way. But I’ll be back on the horse for the remainder of the year. This way, at 2019 start, I’ll be able to try working vac hanging into play. A full life…it is what it is.

Session Notes

1. Edge for around 130 minutes, massaging occurs concurrently during edging.

2. Perform 11 minutes of clamping during edging time. Due to edging habits, kegeling isn’t as easy. Some residual fatigue is slowing the hard kegels.

3. Took a break and performed 6 minutes of additional clamping then orgasmed.

4. Warmed down with light stretching in front of IR lamp.

Other Notes

1. Expansion was at great levels for this session. Even after a decon.

2. Edema present under glans. Significant but not excessive. A predictable amount, considering the heavy clamping after 23 days off.

3. For the second session of clamping, broke clamp. Makes a second broken clamp in my PE career, both with this aggressive clamping routine. Which may correspond to larger base girth measurements. I will measure it again and consider a log entry.

Pre pump unclamped was not checked
Pre pump clamped was 6.53” MSEG
Pre pump clamped #2 was not checked prior to orgasm. Appeared larger. Ah well.

4. Get back into the swing of things one step at a time.

I’ve learned, after losing a good 4 rounds, that I have signifcant difficulty running extended edging sessions and two clamping sessions prior to pumping. Whether it is self-control issues or just not possible due to increased sensitivity I have no idea but I have to admit some kind of failing to make progress.

I did manage the double clamping and pumping today but…still very tricky.

Also, I’m *constantly* listening to my subliminals. I have found a speaker that I keep in my pocket and have the list on auto play all day. The speaker has a 24 hour battery life and is in my pocket, in my bed when I sleep and on my desk at work. This has been the case for months.

Onward to the pumping! Damn it!!
Session Notes

1. Edge for around 90 minutes, massaging occurs concurrently during edging. IR lamp used and Wicked Silicone Lube for this. Heating pad set on 3 setting, 2 hour shutoff. Changed heat setting to 4 after entering the tube and it remains at 4 for the rest of the session.

2. Perform 10 minutes of clamping during edging time. Perform very hard kegels to maintain a very strong erection for most of this time. Perform 5 more minutes of clamping after taking a break prior to pumping.

3. Lube penis and entry of tube as long as my forefinger in depth, with vaseline. Enter tube fully erect. Used heating pad contact for entire session, on setting 3 for warmup time. When entering tube, setting is moved to 4 and stays there, for a gradual warmup.

4. For first 120 seconds (2 minutes), cycling between just at 5HG (0 holes covered) and 7.5HG (2 holes covered). Up cycles were around 2-3 seconds, down was around 1-2 seconds.

5. For 60 seconds (1 minute) cycling between just at 5HG (0 holes covered) and 15HG (3 holes covered) Up times were 2 seconds. Down times were about 3 seconds.

6. For 60 Seconds (1 minute) cycling between 17.5HG, for 1-2 seconds, up cycle takes roughly 5 seconds. Downcycle for 5 seconds.

7. For 60 Seconds (1 minute) cycling between 20HG for 1-2 seconds, up cycle takes roughly 5 seconds, downcycle for 5 seconds.

8. For 60 seconds (1 minutes) cycling between 17-18HG and 5HG using 10 second gradient upwards and stopping at 17-18 for 1 seconds. Down time of 5 seconds between cycles

9. For 60 seconds (1 minute) cycling between 20HG on a 10 second gradient upwards and stopping at 20HG for 1 second or less. Down time of 5 seconds.

10. For 60 seconds (1 minute) cycling between 15HG for 2-3 seconds with a downcycle of less than 1 second up to 2 seconds. This is done as fast as comfortable.

Total time 8 minutes pumping

11. Post session clamp for 5 minutes under IR lamp.

Other Notes

Special note: I experienced a bit of discomfort and stretching in the area beneath the glans when pumping. Getting back into high pressure, even for just 8 minutes, is still highly taxing and may not require the sudden and abrupt return that I tend to do. I feel that my penis is fine but…this is a reminder, high pressure is serious business.

1. Expansion was at levels that have grown into the new average, though are still quite good and my post pump clamped rivals my previous record.

2. No edema seen until post pump clamping session began. Noted Post Pump clamped girth below, some of which must be edema but unknown how much.

Pre pump unclamped was not checked
Pre pump clamped was 6.45” MSEG
Pre pump clamped #2 was 6.41”MSEG
Post pump unclamped was 6.25” MSEG (presence of mind to check it this time!)
Post Pump clamped at 6.61”
**Post pump clamped area below glans girth: 6.53”

3. Moving to early morning PE again. Seeing how it works. Sex drive gets me up to masturbate so I’m trying to channel that into the edging I use to start these sessions.

4. Need to find a turn key hose clamp that can be opened and closed manually without a screwdriver or nut driver.

Housekeeping

I write the title “Lost Round” to mean more “a round no one made note of” because those sessions do not include pumping. They are vital and count in my research and are numbered separately so that when going through this log my methods can be understood and duplicated, unplanned sessions, mistakes and all.

Routine Notes

Today’s routine was:

5 minutes clamping at 6.45” clamped MSEG
10 minutes clamping at 6.49” clamped MSEG

Used IR lamp. Edged over course of an hour.

Other Notes

1. Difficult to warm down when sex drive is high. Orgasm pleasure has been increasing.

2. Found and ordered turn key metal hose clamps. Will update with results after wrap is decided upon.

I’ve started using the hose clamp in sessions in five minute increments prior to the workout and after. I’m unsure if I will go further than that but these are short term goals to maximize my expansion patterns.

Session Notes

1. Edge for around 90 minutes, massaging occurs concurrently during edging. IR lamp used and Wicked Silicone Lube for this. Heating pad set on 3 setting, 2 hour shutoff. Changed heat setting to 4 after entering the tube and it remains at 4 for the rest of the session.

2. Perform 10 minutes of clamping during edging time. Perform very hard kegels to maintain a very strong erection for most of this time. Perform 5 more minutes of clamping after taking a break prior to pumping.

3. Lube penis and entry of tube as long as my forefinger in depth, with vaseline. Enter tube fully erect. Used heating pad contact for entire session, on setting 3 for warmup time. When entering tube, setting is moved to 4 and stays there, for a gradual warmup.

4. For first 120 seconds (2 minutes), cycling between just at 5HG (0 holes covered) and 7.5HG (2 holes covered). Up cycles were around 2-3 seconds, down was around 1-2 seconds.

5. For 60 seconds (1 minute) cycling between just at 5HG (0 holes covered) and 15HG (3 holes covered) Up times were 2 seconds. Down times were about 3 seconds.

6. For 60 Seconds (1 minute) cycling between 17.5HG, for 1-2 seconds, up cycle takes roughly 5 seconds. Downcycle for 5 seconds.

7. For 60 Seconds (1 minute) cycling between 20HG for 1-2 seconds, up cycle takes roughly 5 seconds, downcycle for 5 seconds.

8. For 60 seconds (1 minutes) cycling between 17-18HG and 5HG using 10 second gradient upwards and stopping at 17-18 for 1 seconds. Down time of 5 seconds between cycles

9. For 60 seconds (1 minute) cycling between 20HG on a 10 second gradient upwards and stopping at 20HG for 1 second or less. Down time of 5 seconds.

10. For 60 seconds (1 minute) cycling between 15HG for 2-3 seconds with a downcycle of less than 1 second up to 2 seconds. This is done as fast as comfortable.

Total time 8 minutes pumping

11. Post session cable clamp for 5 minutes under IR lamp. Take a 10 minute break then 5 minutes hose clamp under IR lamp.

Other Notes

Special note: I experienced a bit of discomfort and stretching in the area beneath the glans when pumping. Getting back into high pressure, even for just 8 minutes, is still highly taxing and may not require the sudden and abrupt return that I tend to do. I feel that my penis is fine but…this is a reminder, high pressure is serious business.

1. Strong expansion, pushed into new territory today.

2. No edema seen until after hose clamp post pump. So, at the very end and only under the glans, as usual. Not measured this time.

Pre pump unclamped was 6.18” MSEG (checked this time)
Pre pump cable clamped 10 minutes was 6.49” MSEG
**Pre pump turn key hose clamped 5 minutes was 6.49”MSEG (note the hose clamp)
**Pre pump post erection temp gains measure was 6.37” (this number didn’t used to fluctuate much past pre-pumped and it appears temp gains after turnkey hose clamp are significant enough to note)
Post pump unclamped was 6.41” MSEG
Post Pump cable clamped 5 minutes at 6.49”
**Post pump hose clamp 5 minutes with several cranks in the last minute : 6.65” (added this metric to check maximum expansion concepts.)

Temp gains after workout completed at 6.41” MSEG

3. Sessions are stretching into the 2.5 hour total time frame. Morning is best for this.

4. Turnkey clamp is adding new dimension of expansion on demand.

*5. Edema was more than expected after 10 minutes past cool down. Picture here: Post Round 54: Uncensored with notes.

Housekeeping

This log will conclude at the end of this year. A new one with a different and fresh number format will start when I’m hanging, clamping and pumping.

Routine Notes

Today’s routine was:

10 minutes cable cuff clamping at 6.37” clamped MSEG

90 seconds hose clamping. Unmeasured.

Used IR lamp. Edged over course of around 40 minutes total.

Other Notes

1. Hose clamp was not properly aligned. It caused an uneven pressure spike and the same capillary bulged when I torqued the pressure down. I removed the clamp as soon as I observed it.

2. I will redo my cushion to be clearly wider than the leather barrier. Instead of splitting the silicone sleeve in half I should have slit it on one side to have a wider barrier. I’ll have to ruin another sleeve but I think it’s worth it so far.

3. Last night I had several stone hard erections. I think my usage of the hose clamp is right on the money. Edema, while a negative PI, isn’t necessarily a factor slowing or lessening the effectiveness of my workouts. Odd conclusion but true thus far.

Hey toughtfulgold,

really looking forward to your conclusions ;)
Unfortunately it will difficult to tell if PE4F style of pumping is working as it seems that your focus switched to clamping (as I expected in the beginning of your routine).

By the way I experimented a bit with high pressure cycling too this year (about 5 sessions at 17-20 inHG).
I know it is not 100% comparable to the PE4F-style of pumping.
But in my case I will stay with long low pressure sessions. It works better for me. The expansion is so much better and longer lasting.
My future high pressure range for longer sets will be at 7-9 inHg and max 12 inHG for high pressure spikes. My absolute limit is gonna be 15-17 inHG.

So unfortunately I won’t try PE4F pumping. Maybe later down the road ;)
But I learned some things and will do a experiment myself next year with a style I developed after the experiments (dynamic pumping with a semi-open valve (cheap pump balloon) for 10s and 15-30s holds with a closed valve (about 7 inHG). A set is gonna be 7 Min. )
Unfortunately my IPR routines this year worked too well regarding the time investment. So no pumping in the near future as I just started a new cycle.

And please: Do the the switch already to a real clamping routine and use pumping as I side kick to re-establish bloodflow ;)
Clamping can be combined with other exercises too while being clamped (see redzulu’s clamping guide pdf on mos).
I think you are conditioned enough to step into this territory.

Wish you the best and hopefully you will ditch the new clamp before you injure yourself.Maybe you should contact MaleHanger for his clamp.
I think it would be a perfect match (less pressure on the dorsal area) and current goals (hardcore clamping).

By the way, thanks a lot for this great thread. Really appreciated. Hopefully I don’t come off as a party pooper ;)

I will be sure to include all of my conclusions at the end of my experiment here. Thank you for your input. I’ll give the Male Hanger clamp a look.

Working my pattern into place.

Yesterday I clamped for 6 minutes with a cable clamp under IR heat. I reached 6.41” MSEG at that time.

Today’s session is below and starts even stronger.

Session Notes

1. Edge for around 70 minutes, massaging occurs concurrently during edging. IR lamp used and Wicked Silicone Lube for this. Heating pad set on 3 setting, 2 hour shutoff. Changed heat setting to 4 after entering the tube and it remains at 4 for the rest of the session.

2. Perform 10 minutes of clamping during edging time. Perform very hard kegels to maintain a very strong erection for most of this time. Perform 4 more minutes of clamping after taking a break prior to pumping. 4 minutes performed with turn key hose clamp.

3. Lube penis and entry of tube as long as my forefinger in depth, with vaseline. Enter tube fully erect. Used heating pad contact for entire session, on setting 3 for warmup time. When entering tube, setting is moved to 4 and stays there, for a gradual warmup.

4. For first 120 seconds (2 minutes), cycling between just at 5HG (0 holes covered) and 7.5HG (2 holes covered). Up cycles were around 2-3 seconds, down was around 1-2 seconds.

5. For 60 seconds (1 minute) cycling between just at 5HG (0 holes covered) and 15HG (3 holes covered) Up times were 2 seconds. Down times were about 3 seconds.

6. For 60 Seconds (1 minute) cycling between 17.5HG, for 1-2 seconds, up cycle takes roughly 5 seconds. Downcycle for 5 seconds.

7. For 60 Seconds (1 minute) cycling between 20HG for 1-2 seconds, up cycle takes roughly 5 seconds, downcycle for 5 seconds.

Total time 8 minutes pumping

11. Post session clamping omitted due to orgasm.

Other Notes

1. Strong expansion. Note: Tube is packed within the first minute of using the pump. I would doubtlessly say the clamping primes me for this but this is the first time I’ve checked early enough to make a note of it.

2. No edema seen at all. Looking at the expansion patterns and the way I’m not seeing temp gains after exiting the tube I have come conclusions that these numbers are bearing out.

I am packing the tube too early for more expansion.
Packing the tube is preventing the edema.
Expansion from clamping first is the same expansion limitation I would reach if I skipped clamping and only pumped.
Much more chatter about this concept and my thoughts here: Turning Point: Packing 2” Cylinder and direction to take from here.

Ergo, I should start experimenting with my 2.25” tube and see how long (and if) I can pack it up to the glans or not.

Pre pump unclamped was blank, forgot to check
Pre pump cable clamped 10 minutes was 6.49” MSEG
Pre pump turn key hose clamped 4 minutes was 6.57”MSEG
Pre pump post erection temp gains measure was 6.25”
Post pump unclamped was 6.29” MSEG
Post Pump cable clamped not checked due to orgasm
Post pump hose clamp not checked due to orgasm.

3. Starting with the heating pad on setting three felt warm for the first time today. I almost dialed it down but I know that temperature is safe for my skin. I believe I’m getting a bit more sensitive, with all the subliminals and the 3-4x daily masturbation practices. Slowly but surely recovering penis health after years of focusing and trying.

4. I used a wider cushion with the turn key clamp for the 4 minutes I used it today. Ruined another soft sleeve but no blood or bulging. Safety is seemingly panning out for this, as much as one could hope.

5. I need epoxy to patch the 9/64” hole I drilled in my tube prior so I can put 4 of the 1/16” holes I use with my 2” tube in for me to pump with it. Hopefully I resolve this issue today or tomorrow so I’m on track for Sunday’s pump session.

At some point early on in the thread, probably on the first or second page, I used geometry to decide that the 1/8” safety hole was stupid. The same surface area (within a very small margin) was had by (4) holes at 1/16” inch and made calibration of pressures used in the tube far more predictable than twitches and thickness of your fingerprint that day.

So, to do PE4F pumping, I started with one hole at 9/64” (because my 1/8” drill bit had broken on another job and nearly taken out my eye) and found that I could not reliably reproduce any pressure I wanted to target according to my gauge. Looking at the hole concept I did the surface area of a 1/8” diameter circle and found that the surface area of (4) 1/16” circles was very similar and that covering one hole, two holes or three, no matter which ones reproduced the same pressures every time. So I decided to use my fingertip on the 4 smaller holes.

This left my original 2.25” LeLuv cylinder with one 9/64” hole drilled in it that I really don’t want. This is how I repaired it.

First, epoxy for this application is overkill. And I kept looking for the perfect one as most say doesn’t bond to polyethylene plastics. Then, they said “scuff the surface” and “make sure compound contacts both surfaces” and really, epoxy is made to bond two items together, fix a crack and reseal it. Not plug a round hole. I’m sure I could have gotten some epoxy to work but my concern was the non-porous nature of the outside of the tube would let my plug eventually fall off of the cylinder. Plus I hate mixing and setting epoxy.

If you've cracked a tube…

That being said, if you have cracked your tube or broken your pump cylinder, epoxy is the method I would recommend. A cracked area, not being buffed or finished, would likely already be porous and not require an additional scuffing step. Simply applying epoxy in the crack on one side of the damage and on the outside of the cylinder would be enough adhesive. Afterwards, securing it in some kind of vice for the compound to cure, would be the way I would go if I had a valuable cylinder I wanted to save from the trash can. Then, for good measure, running some of the tape featured later in this post along the outside of the crack for good measure would be a smart move also.

As it happens, I was at a hardware store and the old guy in it saw me wandering around and asked what I was doing. I said I was sealing a clear jar and wanted an airtight seal, that it didn’t have to be a clear seal. After explaining my epoxy issue he asked why couldn’t I use tape? Before I could say “Tape prolly ain’t gonna hold up” he disappeared and reappeared with the tape seen in Figure 1. Looking at the packaging, if the adhesive can hold underwater it should hold up to what is a relatively light level of abrasion and interference. Pressure, if the tape doesn’t fold into the hole, is all I’m concerned with. Plus it’s super easy to apply. I went about it super complicated of course.

Steps Taken for Repair

1. Package of the tape used. I don’t think regular scotch packing tape would hold up long term as the glue would likely give or the plastic become brittle. Not sure, went with this instead.

2. I cut a small square over the hole and put it on. Then took the excesss from that first piece and reinforced that. Then took a square over that patch on all sides and a square to overlap that on all sides. So that if the original patch starts to give way, it has to tug multiple levels of reinforcement of equally sticky and strong tape in different directions to diffuse inward forces on the surface of the entire patch. You can see this in Figure 2.

3. I picked a site for my 4 holes then drilled them through the tape and reamed them without wobbling the bit so that the holes would be clean.

4. I found that tape being drilled through was simply not adequate to ensure that the holes would not become plugged by ragged tape edges so I took my utility razor and cut a section of the outer part of the patch out, around the holes. You can see this in Figure 3.

5. I visibly checked the holes for perfection, which I think is reasonably round and clear of obstruction. The spiral pieces of acrylic generated by the drill left inside the tube were easily removed by pushing a T-Shirt into the tube and twisting a few times.

6. I checked calibration of the holes with my pump. The pressures read well within a margin of error of the exact same as covering the same number of holes on my 2” cylinder.

Calibration of Cylinder used for PE4F Pumping

1. No holes covered- 5HG
2. 1 hole covered- 6HG (setting is not ever used, I skip to 2 holes covered but I drilled all 4 to have a lower resting pressure with all holes uncovered)
**3. 2 holes covered- 9.5HG (3 holes covered has routinely been one of the more fluctuation prone settings, it goes as low as 7.5HG and I can’t say exactly why but my logs have shown this over the 10 months of experimentation)
4. 3 holes covered- 15-16HG
5. All Holes Covered- Full Vacuum

Calibration of Cylinder was performed on my right pectoral muscle. This has proven to expand a bit under vacuum without significant pain and the pressures are very close to what is shown on the gauge when using the cylinder on my penis.

Other Thoughts

Honestly, another LeLuv Tube wouldn’t have broken the bank. However, repair still saved me $30 and if you’re using more expensive tubes from VacuTech or Pumptoys this may be the difference between a dead in the water campaign or success because $150+ is a hard pill to swallow because you used the wrong drill bit for a few seconds.

Picture quality isn’t great because taking pictures of clear tape with a cellphone sucks. But…I hope the general idea is transferred to you, the readers.
