What is this?

[TC]

Does anybody know anything about this?

Anyone?

Never seen it. Looks like a brake drum attached to a MA system (going out the right side of pic).

Doesn't it look like it needs the end of the rope fed around the drum? Anybody see it differently?

Where is the picture from? Looks like maybe the internet? What site?

 

[maarten]

The horizontal set up makes me wonder if there is more to it then meets the eye

 

[treedimensional]

Well it appears to have at least a 2:1 on the right side of the picture!

It looks like a really well designed and built friction device. I see no indication that it has any moving parts.

It could be called 'Take three wraps' if that name isn't already taken.

Hey Grover, thats what happens when you ONLY look at the pictures in the magazine!

Which magazine was it in???

Or "wrap three times" on my window.......

Looks like a friction device to me as well. Take a bigth and pass through that round ring on the front, and then spin wraps on after that, use the hook to lock it off.

Thats what I got from the picture at least?

Somewhat similar to this one that Jerry built.

I believe it IS one of Jerry B's lowerig devices, In fact I think those are his gloved hands,

 

[carya]

a shiny new torture device from that funky imagineer Pinhead

I agree. I believe Jerry shows that in his new Rigging DVD'S. There is a wealth of info in those DVD's

It resembles a cavers' rappel spool. Is that ring welded to the rest of the device? It is hard to tell with various pieces of metal lying around. Many rappel spools were one-of-a-kind devices made by a welder. I can't think of any large scale production, or even small scale. The device it most closely resembles is http://storrick.cnchost.com/VerticalDevicesPage/Rappel/SpoolPages/HSpool579.html

Storrick's site is chock full of devices similar to this.

If those hands were Jerry's I am betting that he would have less baggy gloves on.

Grover...where did you get the image from?

In the end, another clever way to have uniform control of friction with the ability to easily vary the total amount of friction.

If rigging friction is scaled from 1 to 100, tree friction is variable in about 20 unit increments, maybe sometimes 10's. Using friction devices allows us to have control in single and sometimes decimal point units. What a change from 'take three wraps' of ancient history.

Does anyone else remember the fella from the old ISA forum named 'take three wraps'?

 

[Gerald_Beranek]

Baggy gloves? That device is version of a portawrap I made about 15 years ago. In the pic it was being used as a rope grab at the end of a tackle for drawing and then lowering.

When used as a termination/grab for pulling it's gentle on the rope. A regular portawrap could be used the same way though.

 

[chris_girard]

Thanks for answering our question Jer.

I thought that that was one of your custom devices. Does it still see a lot of use?

Tom, I remember reading some of 'take three wraps' posts over on the old ISA forum. Can you even still access that old site anymore?

 

[Gerald_Beranek]

It doesn't see a lot of use, Chris, because it's only good for half inch line and is a bit cumbersome to load. Funny though, the design is fairly close to the modern portawrap, but came about as an idea sometime before.

Goes to show a lot of people in the business have similar ideas at about the same times.

Chris,

There are portions of the original ISA forum around. Try looking in 'The Way Back Machine'...not the one from Rocky and Bullwinkle though
