Posted on December 09 2014 by RopeMarks

rm20140221_4_5021_cover.jpgWe paid a visit to the beautiful Sinteque for the sole purpose to have my property molested by someone else then me!

First Dutch Dame was made to wait in a agura shibari, not able to go anywhere, contemplating what might be going to happen...

When Sinteque arrived she played a little with Dutch Dame, untied her from the agura, only to prepare her for a sakasa ebi shibari.

After playing with Dutch Dame in the sakasa ebi a tight rope gag and even tighter kubi nawa was added for suffering of Dutch Dame and enjoyment of the on-viewers.

Carabineers

Posted on November 17 2014 by RopeMarks

Carabineers

A recent carabineer failure at a Circus performance has raised some important questions in the aerial arts community. While I know very little about what caused this particular failure, I want to address some general things about the pros and cons of carabineers and how they fail.

Materials

Carabineers are made of either steel or aluminum. Steel is a very ductile metal - meaning that it deforms (bends and stretches) long before it breaks. This is good because it usually gives the user a chance to see that the metal has been stressed well beyond the working load limits long before it breaks. Aluminum has very little deformation before it breaks (literally snaps); therefore, there is no warning that the metal has been over-stressed. Also, aluminum has "micro-cracks" and imperfections that are impossible to see with the naked eye. I always recommend steel carabineers for aerial work.

Bend carabineerThis steel carabineer was pulled to destruction. Note how the pin on the gate is torn out. When this occurred, the integrity of the carabineer was lost, and the body began to bend open.

Locking and non-locking gates

The gate of a carabineer not only holds part of the load, but is also critical to the overall strength of the carabineer. What most people do not realize is that the gate of a carabineer can be "popped" open by a shock load, and if this happens, the carabineer immediately loses most of its strength. For example: an aluminum carabineer with a 24 kN BS with the gate closed, is only rated for 7 kN when the gate is open; a steel carabineer rated for 45 kN with the gate closed is only rated for 15 kN with the gate open. To prevent the gate from accidentally opening, I recommend that aerials use carabineers with a locking gate. (I like auto-locking gates because the user cannot forget to lock them).

Snapped carabineerThe gate of this aluminum carabineer "popped" open under a shock load, and the body snapped into two pieces.

Carabineers vs. Shackles

Aerial performers like carabineers because they are easy to connect and disconnect with one hand; they do not have any parts (shackle pins) to drop. However, carabineers are (for the most part) "recreational hardware" and not intended for industrial use. Also, many users of carabineers do not know that the rating on a carabineer is its breaking strength and that 1 kN is equal to 224.8 pounds. The weakest part of a carabineer is the gate (even a carabineer with a locking gate). When a load is on the carabineer, part of the load is held by the gate - it is in tension. Because the gate holds part of the load, the gate should be carefully checked before each use. Check to ensure that the gate is working properly - does it close easily and completely with any issues? Check the "pin" on the gate and the "hook" on the body of the carabineer. If either of these show any damage, or if the carabineer does not close easily and completely, discard the carabineer.

Shackles are industrial hardware. They are rated with a working load limit (WLL) - often in tons. The actually breaking strength is often 5 or 6 times the WLL. Unlike a carabineer, the gate of the shackle (the shackle pin) is in a "double-shear." Metal is much stronger under a double-shear forge than under tension. Shackles are only made of steel, so they deform long before they fail. You should always check to ensure that the pin of the shackle is not bent and that it screws completely into place in the body of the shackle. If the pin is bent or the pin does not screw completely into the body of the shackle, discard it. Also, "mousing" the shackle pin with wire or a nylon tie is important if the loads swings or is in place for an extended period of time.

What if you drop a carabineer on a concrete floor?

Probably everyone has heard that if you drop a shackle or carabineer on a concrete floor, you should discard it - right? Well, maybe this report from Richard Delaney in Australia might provide some insight into this myth.

I discussed our destructive testing of 100 biners in a thread a while back. We were donated a bunch of alloy bineers that had been 'retired' so we dropped them all 5 meters onto concrete 5 times and then gave 20 of these some extra special treatment with a lump hammer to give them the sort of injury that would stop most normal people from using them. Then, we broke them all. All broke at or above rated strength, except one - ... this still could have been one of the 3 in ten-thousand that will break low even brand new off the shelf.

Also, I did 3 steel and 3 aluminum a while back that had been dropped 275m onto plate steel over concrete. Aluminum broke above rated; steel were deformed and unusable post drop.

The one in the 100 that broke low was about 10% below rated from memory. Hence, I'm a big fan of reputable manufacturers who proof load all bineers to 1/2 mbs.

Pile of broken carabineersSome of the carabineers Richard destructively tested.

To sum this up, if the carabineer is not bent and the gate operates properly after a short drop, it is OK.

Design factors

As noted above, most industrial hardware has a design factor or either 5 or 6, whereas recreational hardware is not rated with a working load limit, but with its breaking strength. When suspending humans, a design factor of 10 or greater is recommended. Even then, that does not guarantee that a failure will not occur.

When possible, there should never be a situation where the failure of a single component can result in a catastrophic failure. In other words, include a backup for every component, and if some component cannot be backed up, make sure the design factor is double what you would normally use and that you inspect it very carefully before every use.

Conclusion

For industrial applications, or where shock loads are common, locking steel carabineers are usually fine for most aerial work if the design factor is 10 or above. Still, careful inspections of all your equipment is the best way to prevent an accident, so inspect, inspect, inspect.

RopeMarks Ryū, shibari workshop

for Kink Info

Posted on October 11 2014 by RopeMarks

### For the Dutch among us:

Het is een spannend voorspel, het wordt over het algemeen ervaren als de beste vorm van BDSM, verdiept het vertrouwen en respect tussen de partners, het ziet er erotisch en opwindend uit en is gewoon leuk om te doen; Japanse bondage ook wel shibari of kinbaku genoemd.

RopeMarks Ryū omvat een traditionele style, ontwikkeld door Bob van RopeMarks, die de synthese is van de vele aspecten van de bedrieglijke eenvoud van Kinbaku en Hojojutsu. Het is ontworpen om je essentiële vaardigheden en technieken aan te leren met de nadruk op technische, fysieke en emotionele veiligheid.

Wat moet je weten

Voor deze middag is kennis van shibari geen vereiste. We zullen ter plekke het nivo van de workshop aanpassen aan de kennis van de deelnemers zodat zowel de rigger (de persoon die gaat bonderen) als de “bunny” (de persoon die gebonden gaat worden) profijt hebben van de technieken, patronen en posities de je gaat leren.

Wat ga je doen

De RopeMarks Ryū put uit een lange geschiedenis van kennis, informatie en ervaring. Hiemee hebben we de mogelijk om naast een vast programma er een interactive middag van te maken waar iedereen het meeste uit kan halen.

De nadruk zal liggen op een hands-on ervaring en zaken die we zeker aan bod willen laten komen zijn o.a. de basis blokken van een stevige en safe Japanse bondage

* de Tejou shibari, binnen RopeMarks Ryū de basis techniek voor een boei van touw
* de Ryoute kubi shibari, de polsen gebonden
* de Ushiro takate gote shibari, een bovenlichaam bondage
* Gote, de bovenlichaam bondage, variaties

Wat heb je nodig

Om deel te nemen aan deze RopeMarks workshop voor Kink Info is vereist:

* Dat je komt als (gelegenheids)stel (de prijs is dan ook per koppel)
* Makkelijk zittende kleding
* 4 stukken touw van 7-8m (6-8 stukken als je later verder wilt bonderen)

En last but not least, dat je motivatie, enthousiasme een open-mind en humor mee brengt.

Club update, Ryouashi gattai ichimonji shibari

with Dutch Dame

Posted on October 08 2014 by RopeMarks

Ryouashi gattai ichimonji with Dutch DameToday we were honourable guests in "the loft", a charming place with some interesting additions for fun rope-play (or just bdsm play for that matter). The atmosphere oozes relaxation and coloured my decision on the paces to put the amazing Dutch Dame, my toy for the day, through.

For starters my toy was allowed to show off her killer body, feet in ballet ankle boots, being the first stage in her bondage, preparing for things to come

Now it was time to start with her full immobilization. A simple gote being the choice of restriction. Even tied she tried to show us her vjj, but after a Master to slave correction she found herself on her knees, showing her best ASSet

At this point I could spend a considerable time with the ass of Dutch Dame, but my intend was a full immobilization before she had to pleasure of me playing with her ass and luscious body. I tied her legs together (ryouashi gattai ichimonji shibari), made her sit and settle in this tie and watch her expression change into submission.

When it started to look that the bondage Dutch Dame was wearing so beautifully started to feel comfortable it was time for some tension and forced exposure, I suspended her bound legs and twisted her upper body.

The final additions to this beautiful Dame in a beautiful tie we take away her senses and add an extra level of difficulty, suffering. We bag her head with a black bag held in place by a tight leather collar around her neck. Just for fun a rope gag is added. Now the breathing of Dutch Dame becomes a conscious action making her have to choose between feeling what we will do to her exposed vjj and ass and getting air.

Strict collar, tightly bagged, feet in ballet ankle boots, legs bound and pulled up exposing her vjj and ass for play... it continued to become a very fun afternoon...

Wild beaming

with Hester Scheurwater

Posted on September 23 2014 by RopeMarks

Some time... years ago (three and a half to be exact) I made a casual remark about cooperating in a wild beam action. Now, I think it is about time that we show you the results...

Together with Dutch artist Hester Scheurwater and international model Dutch Dame we created two Japanese bondage scenes (shibari / kinbaku) ment for projection on tall and large buildings, wild beaming. Without further ado, a few short clips of the scenes projected on building in the Netherlands.

Download this video.

Wild beaming with HEster Scheurwater and Dutch Dame

During the creation of the video for wild beaming Hester made some behind the scene shots that we think are worth it to be seen:

RopeMarks Ryū

lifestyle, courses, tuition, workshops

Posted on September 14 2014 by RopeMarks

The past period we have been spending a lot of time to innovate our previous workshop section into something vastly more appropriate; 

RopeMarks Ryū.

RopeMarks Ryū is one of, if not, the oldest traditional Japanese rope bondage Ryū in the Netherlands and Europe.

RopeMarks Ryu glossary screen printWe think that besides the unique RopeMarks style that we are offering to teach we also have something that has not been seen in the scene before, a visual, searchable glossary. The current body already holds a vast amount of names and terms and with the information we got coming it is looking forward to become a tome of quick searchable knowledge, with pictures.

See for yourself

Against all good advice we will blow our own horn and show all the good things people have said about RopeMarks, our teaching, our experience and our high level of knowledge in the testimonials section.

"[...]his experience is so big, it radiates from him."

"Not only is Bob an impressive rigger, he also has the ability to transfer his vast knowledge in a solid and entertaining manner."

See for yourself

Keep in mind that all of this is just the start of the RopeMarks Ryū section. You can look forward to free video tutorials more information on the subject of Japanese rope bondage and a real life Amsterdam based Dojo. We are really looking forward to the direction this is going.

Club update, The Pillory

with Dutch Dame

Posted on September 04 2014 by RopeMarks

The Pillory, with Dutch DameWe have spend an awesome time in a medieval dungeon with among others a working pillory. A pillory that we just had to put to the test, RopeMarks style!

We have the amazing Dutch Dame strip to nothing but her high heels, then place her in the pillory. A small shock goes through her body when it closes around her neck and she realizes this experience is going to be for real.

The pillorie's holes for the wrist are relativly big, to keep Dutch Dame from getting her hands out we put some rough metal cuffs on her wrists, beautifully appropriate for the location.

As a warm-up, and make the experience as real as it gets we leave her there for some time... Next time we must have a clock next to the equipment

Next we lower the pillory, forcing our beautiful victim in a bend-over position and tie her ankles, spread legged, to the rings at the side of the platform she stands on.

A butt exposed like that is screaming for a spanking... so we comply, and just for good measure we decorate her tits with a pair of painful nipple clamps.

By now resting her neck and wrists on the hard wood, the rough and heavy metal wrist cuffs, the nipple clamps and the uncomfortable forced bend-over position is causing some very sexy movements from Dutch Dame that we enjoy much. We see no reason to interrupt this scene.

Next we lower the pillory to its lowest position forcing Dutch Dame on her knees and making it more difficult not to rest her neck on the hard wood. The strain on her amazing body is showing and she is searching for the most comfortable position to be able to handle this torment... but, really, there is none.

As our final torment, mix in some kinbaku in this medieval scene, we apply a ryo-ashi sakasa zuri. We suspend our willing victim by the ankles only while still in the pillory torment. This is forcing her neck to rest on the hard wood, in effect chocking her (a beautiful struggle) her wrists with rough metal cuffs are going nowhere but are a torment for her arms as she struggles for freedom and her nipple clamps are swaying like flowers in the wind causing sweet torment on her nipples with every movement.
