YouTube Account Suspended -- Where to Find My Videos

Topologist

I've been hearing from a lot of you looking for my videos, after my YouTube account having been suspended. Don't worry! All my videos that were on YouTube are also available on this site, and on my Vimeo channel.

Why did this happen?

The YouTube content review process is set up in such a way that when they think you've done something wrong, you get one appeal (which you must make without knowing the reason for your content being flagged), and if you lose that appeal, there is no recourse whatever; nor do they provide any feedback on why any such decisions are made. This makes YouTube inherently hostile to controversial content, such as content that skirts close to sexual topics, because every time a user flags something, there is a chance that the reviewer of your appeal is having a bad day, or also doesn't like the content, or whatever -- and if they reject your appeal, you're hosed.

What can be done about it?

Most importantly, if you find a broken link to a...

January Intensive & February Ropecraft

Topologist

I'm happy to announce two exciting new events I'll be teaching at:

January 9-10th in San Francisco, I'll be running the first-ever Core Rope Curriculum Bondage Fundamentals Intensive. This will be a full weekend of instruction -- what would normally be 5 classes worth -- covering a huge variety of restrictive and decorative ties and techniques.

February 19-21st in Austin, I'll be presenting two classes at Ropecraft, a brand new rope conference put together by Graydancer; this should be a really interesting event, as Gray is one of the most consistently thoughtful voices in the conversation around approaching BDSM education with modern pedagogical tools.

Updated CRC Class List

Topologist

Over the summer I've been quietly reworking the Core Rope Curriculum to include my latest research and discoveries, get beginners proficient more quickly, and provide a more unified online and offline learning experience. I've now updated the CRC Overview Page to reflect the new curriculum structure (with 8 rather than 7 levels), and include a list of the 2-hour class modules composing levels 1-3. For students taking classes in San Francisco, this will hopefully give you a better idea of where each class fits into the big picture.

For those learning online, keep an eye out over the next couple months for new features and content based on the updated curriculum.

Comments Should Now Be Working Again

Topologist

Someone reported to me they were having trouble commenting on ties -- looking into it, it seems to have been broken for a while. That should now be fixed. Sorry about that. Please let me know any time you're having problems with the site!

Upcoming Intensives in San Francisco and Baltimore

Topologist

I have two upcoming suspension intensives; in Baltimore Sep 12-13th I'll be doing a 2-day suspension intensive, and in San Francisco Oct 3rd I'll be doing a one-day introductory suspension intensive that will be the first in a new series of suspension classes running Oct-Jan.

I know some of you have been wondering about the lack of posts here, and particularly the lack of video updates. Don't worry, more content is coming! The past few months I've been very focused on my in-person teaching efforts, as I've expanded my programs in San Francisco and begun running intensives in other cities. However, I remain committed to the CRC video curriculum as well, and hope to have time to make a new series of videos this fall. Be sure to vote for the ties you want to see on video, I'll be checking the most popular requests when putting together a filming schedule!

Upcoming Workshops in Seattle

Topologist

This coming July, I'll be running a weekend of intensives in Seattle; there will be one track for those already doing advanced rope suspension, and another for those brand new to suspension. See the full details here.

Of course, if you're in San Francisco, you can still always catch me at my weekly CRC classes, and I'll be teaching at Shibaricon next week as well.

Miscellaneous Video Updates

Topologist

I recently posted several videos showing a new approach to second column ties; that is, how to tie another limb into the middle of a rope. That's useful for certain hip harnesses, tying wrists together behind the back, and a variety of bedroom ties.

There's also now a video of the third variation of the Quick Shoulder Harness -- one where you tie it standing/sitting, but it's comfortable to lie back on.

Finally, I filmed a neat elbows-behind-the-head tie which is useful for head support in suspension, or for standalone use as a floor tie.

Two Ways to Add Arms into a Shinju

Topologist

I recently posted videos of two ways to add arms in at the end when tying a Shinju-type chest harness for suspension; one that just adds some simple support wraps, and another that mimics the wraps of a takate kote.

In general, I'm a big fan of tying the arms in last when starting an extended scene, because then I know if the arms/hands start to have circulation/nerve issues, I can untie just the arms and reposition them without having to untie everything else. This makes everybody a lot safer, because bottoms tend to be less reluctant to mention a problem when they know it can be easily fixed and won't spell an end to play.

Of course, sometimes you want to get control of someone's hands right away. In that type of situation, one option is to do a temporary wrist tie, then re-tie the hands at the end of tying other harnesses. That way you get all the benefits of having the hands bound for the entire scene, and of being able to easily reposition them.

Mechanical Advantage and Friction in Suspension Lifts

Topologist

Introduction

While there is a variety of common wisdom regarding the effects of mechanical advantage and friction on suspension lift lines, the only published charts I'd ever seen attempting to quantitatively illustrate the subject were speculative and presented conclusions seemingly defying the laws of physics.

I've finally had some time over the past few weeks to explore this issue in more depth, first developing a mathematical model of the system, and then performing some experimental measurements to test the predictions of the model and determine the relevant coefficients of frictions. What follows are my conclusions from that work.

For background on the type of lifting setup which is discussed herein, please see this illustrated article.

Lifting Force

Let us imagine you are lifting a 100 lb bottom in a single-point suspension -- or, alternately, that you are lifting 100 lb worth of the body weight of a heavier bottom (for example, lifting their hips while their chest is...

YouTube Videos Fixed

Topologist

I know some of you were having trouble watching some of the videos hosted on YouTube this past week; it looks like this was due to a recently introduced bug in the YouTube player used by some browsers, particularly Firefox. I've been able to work around the issue for now, so everything should be working again -- and I'm continuing to gradually move stuff over to Vimeo, which seems to be a more reliable platform.

Please let me know if you continue to have playback issues! Also note that for those on slow/unreliable connections, the video files can be downloaded for offline playback from my Vimeo channel.
