Would someone please write this article?

I'd rather not have to re-invent the wheel...

Steven, I thought I saw that you use one at your gym.

Scotty made one for his own home use.

I did already Google as best as I could.

Please? Gracias.

Its just a simple pulley system, right? Theres numerous ways to do it. None of them are 'right,' you gotta make it work with the set up you have :rolleyes:

Jake,
I understand what you're saying. Before CF, people thought pull-up bars were "simple" too, until a bunch of the old style ones couldn't handle the force of kipping.

Questions like, where to put the pulley (straight up, or forward of the rings)? I'd just rather know than try to figure it out or worse, have a problem mid-air.

I'd simply rather stand on the shoulders of those who came before me.

There's a couple ways to do this... can involved 1 or 2 pulleys depending on how you want to rig it up. 2 pulley system usually goes up to each ring cable origin, one pulley would go up and around outside or down.

1. Use a pulley to a belt
2. Use a pulley to a weight stack (or two with two pulleys)
3. Bungee cords/bands

These work nicely: http://patrickhdonnelly.blogspot.com/2008/08/diy-iron-cross-trainer.html

Took me about six hours to make, I believe, though I'm no craftsman, and I went very slow since I was making measurements as I went. You could do it in 2-3. Well worth it.


The pulley-to-belt system is also a nice option. It essentially halves your weight. by strapping the ring to a rope that goes over a pulley and down to a belt you're wearing. (Each ring has it's own pulley and rope, and the pulleys would then be hooked up top to some webbing or steel cable, like regular rings.)

Blair,
That diagram was exactly what I was looking for. It has been saved to the computer.

Steven,
I caught the two pulley description, the one pulley I didn't quite understand, no need to elaborate though.

Leo,
The pictures you linked to I wasn't able to see. Your site said they couldn't be found.

Patrick,
The gym I go to just got some of those ring iron cross trainers. If I decide to get crafty, I'll look at those plans again. I think I'll be able to make good iron cross progress on just the dream machine alone--along with all the other fun things that can be done on them.

Thanks, guys.

I made my pulley system in about 2 hours and 40 dollars worth of stuff from the local hardware store.
I prefer the two pulley system, one pulley will be a double pulley, with 2 ropes going around it, the second rope going around and over to the second pulley. So you have two separate ropes coming down. On one end of each rope i have carabeaners that i simply attach to a belt i wear when on the rings. Ideally i would want something like this http://www.springboardsandmore.com/proddetail.asp?prod=G-010S&cat=67 which would be better for all types of more dynamic movements on the rings (handstands, inverted cross, etc).
As for the other side of the rope, something like what traditional gym machines have, with the ability to place a pin for various weights would be ideal. I havent figured this part out myself and currently just tie whatever weights i have around to the ropes.

if you have only one rope attached to you, any flipping motion is absolutely out of the question :eek: lol.

crossfit journal #24 has a lot of pictures of their pulley systems including the equipment used at the bottom of the article.

There's photos of cross and front lever in the pulley

that design using the natural mechanical advantage of the pulleys by connecting the rings to them is pretty smart. never thought of that. only problem is you only have one setting. i think i prefer the adjustable weights method. definitely cool though...
