Kaidan Chibusa EnokiEvery August, as Japanese spirits return en masse from the otherworld, Tokyo's Zenshoan temple (map) exhibits a spine-chilling collection of 19th-century ghost scroll paintings

This painting by Ito Seiu, the godfather of Japanese bondage (kinbaku), depicts a scene from Kaidan Chibusa Enoki, an old horror story in which the ghost of a dead painter returns to protect his baby from his murderer, a wandering samurai who fell in love with his wife while he was away painting.

This scroll shows the ghost holding the baby while standing under a waterfall at Juniso (map) (where Tokyo's Shinjuku Chuo Park is now located).

Alright… Sunlight… Sort of, since it’s around midnight in our beloved Amsterdam.

The last two months we’ve been hiding in our man cave… Not a bad place to be considering it has girls tied up al around the place, and high heeled pretties bound and gagged serving food and drinks. But the last two months none of these disctractions could keep us (most of the time) from our goal:

We’ve (finally) brought the RopeMarks mother site into the mobile era!

For those who know; we are now a mobile first, fully responsive website, using micro services for anything data related.

For those who don’t care; you can now watch us anywhere, on any device and it will be awesome!

Bliss, in suspension - part 1/3

with Bliss Theadora

Posted on September 24 2015 by RopeMarks

Bliss in suspension, part 1/3We have a real treat for you, an Australian treat. We got a visit from Bliss Theadora a green haired sweetheart and beauty and we're going to use her for our pleasure...

The arms of her flawless body covered with stunning inkt are quickly tied behind her back and her legs are tied ankle to upper-leg ending in a beautiful agura for a beautiful Bliss.

After enjoying the view we move forward to a low, sideways suspension wiht Bliss still in the agura position. Some lovely sounds are coming from her when she is freely swinging in the air.

We do like to see our girls suffer a bit and wrap a new rope several times around the neck of Bliss and tighten it behind her, chocking her just enough to make her lovely sounds a little louder and little less further apart. We leave her slowly swinging, suffering, suffocating and do nothing but sit back and ejoy ourselves.

At one point we take her down... and then decide otherwise and bring her back up again.. a little and a gag.

In this new pose Bliss has more space to move and not entirely unexpected there are some f*ck*ng movements against her suspension ropes... and a wet spot underneath her...

This is an update in 3 parts, two photo sets and one long video.

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.

Karma

You just have to love her weird and wonderful ways.

We owe you an apology, it has been more than one month that we have updated Club RopeMarks. In the past two months we have had a lot of fun and done a number of very interesting things. We will write blogs about this at a later moment. But we unfortunately have also been on the wrong side of karma, or so we perceived this :)

Our lack of time to update started with having to much on our plate, regular work (yes, for those who don't know, we still hold a regular job, bills need to be payed and you cheapskates don't wish to pay enough for our services to drop that :)) and a number of bookings outside of our home-country, the Netherlands. Actually nothing out of the ordinary for us. But then...

Our main computer decided to malfunction and become practically unusable. being regularly away from home for a longer time in this period did not give us time to fix this and the few moments we did have were spent trying to get the f*ck*r fixed. We ended up replacing motherboard and CPU, no luck, the machine still malfunctioned. So nothing left but get a new computer and in tiny slots (read: graveyard shift hours) set it up, install, configure and restore backups.

This is unfortunate, but hey, things break from time to time. We have a laptop, so mail can be answered and communication can continue... that is, until the laptop decided to refuse to boot... Really, laptops are not my thing, had to bring it back to the seller to have it fixed and fingers crossed my data could be safed.

Nothing left but get my iPad, browse some youtube/vimeo videos and enjoy them, through my iTV, on my television... That's is... if my iTV would start... Nope, nothing, back to the Apple store to have that fixed.

Then I think a nice hot shower and a good, strong, cup-of-coffee will relax me and think about how to sort this is all out and get it all back to a working situation. All soaped up and singing under the shower (now there's a site you will never see :)), grabbed the shower head and *crack*... the shower head breaks, water going everywhere except on me... *sigh*. Finished the shower as best as possible, toweled off and went for that much needed coffee.

Prepare the coffee machine and turned it on... nothing... turned it off and on again... nothing... uttered some foul language and in an OCD-frenzy turned the coffee machine repeatedly on and off again... Obviously, nothing. Of all the things that can break, not the coffee machine, my life-line...

On top of this there are a few things in our private life that keeps us busy but since that has nothing to do with RopeMarks it's none of your business :)

Don't get me wrong I feel blessed to actually have all this technology that can get broken but it is a pain when it breaks, and it's an even greater pain when it breaks all at once. Just another proof that we are greatly dependent of technology nowadays.

Current status:

  • We replaced the coffee machine (no coffee, no life!).
  • The iTV problem turned out to be a from a bad batch and Apple replaced it for me at no cost. Thank you Apple and thank you Apple for not mentioning something about a bad batch sooner.
  • The laptop issue turned out to be a 1:1000000 change of this specific boot-issue to occur. It was fixed at no cost and it will most likely never happen again in the lifetime of this machine.
  • Main computer is replaced and is close to being finished setting up and restoring backups so normal business will continue asap.

Never heard of that serverBesides taking a lot of time to set everything up, migrating our sites and all software and/or installing new and improved versions of software, it looks like we're done, Done, DONE!

The RopeMarks family of site are running on a new server *happy*.

Infinity, by Trevor BrownIt took a number of sleep deprived nights some obscene language and brutal violence, I feel like toppling over at any moment now, but the work is done, Done, DONE!

Should you encounter something that appears not to be working as expected, do let us know please!

New Server

Hi,

server-room.jpgTo all members and visitors of the RopeMarks family of websites. We have just started the migration process to a new server. The initial steps and activities will be invisible to you all but there comes a moment that we have to "flip the switch" to activate the new server.

We will provide a heads-up when we activate the new server.

When the new server is active we expect a short time (with a maximum of 48 hours) where it is possible that you experience one or more of the following issues:

As a member
- Unable to login
- Locked out of your account

As a visitor
- Temporary unavailability of, part of, pages

Everything should be working fine withing 48 hours after activation of the new server. If things are still not working for you after this period, please let us know and we will fix it asap.

Thanx!
Bob
