The Origami Forum

Hello,
I currently got a problem with the diagram of Balrog from Eileen's website

http://spinflipper.com/origami/diagrams/balrog.pdf



In fact, at the step 7-8 I do not understand where are the 4 corners of the bird base.
If we got the corners like
A--B
||||||
D--C
on the step 7, where are these corners on the step 8 ?

And the 3 petal fold and the squash fold must be *in* the paper of the bird base or must be outside ?

Thanks

(first but not last post !)

Ack - that diagram was drawn by a newbie and I'm so embarrassed it's still floating around, but unfortunately I've lost the sources for them so I can't even update it easily.

Anyhow, on step 8, corner A is at the top and front, corner C is top and bottom, and corners B and D are the bottom two ends - take a look at steps 9 and 10 to see how things are lined up. The large bird base creases go under the smaller four folds at the corner.

hum thanks for this help,
but i do not understand how, if the A corner is on the top, how the paper can exceed the size of the bird base on the top of the step 8 ?

Corners B, C and D will stick out a bit further than the bird base but not corner A. In step 8, the top of the model isn't drawn very clearly - it's showing A and C at the same time (you're seeing the front of A and the back of C). In step 9, part of the top diamond should also be lying below the triangular flap.

okay, so i got this for the moment :



my paper on the step 8 is the same as the diagram, with the corners A on the top front and C on the top behind, abd the corners B and D on the bottom.

But when I fold down the A, i do not see the picture of the step 9, cf my picture.

If i continue, I got the step 10 different too, cf my picture too.

Strange isnt it ?

Yep, it's weird, and I'm really going to smack the diagrammer.

Your pictures are correct. In step 10, it's possible that the little petal/squash/frog base thing is hidden beneath the bird base fold. Pull it out from below and then continue onwards, and compare what you get with steps 12 and 13.

thanks you very much for your help !

I have put *out* the little triangle that was *in* the model, and I finished the step 12.

Maybe this post will help the futurs folders of this diagram

You're welcome, and thanks for pointing out the diagram errors. With any luck, no one is going to need to refer to this post after I get around to rediagramming that thing, which, um, should probably happen within the next decade, maybe.

i totally dont understand the petal folds in step 4
can anybody help?

But i dont get the first step, what's with that triangle in the square..
Isn't there a movie or something from it ?
sorry, i'm origami noob

Those triangles (or more appropriately, the edges of the triangles) mark the crease lines that form the petal folds.

precrease the angle bisector to the middle and you will get two sides of the triangle.

Ok, i made the triangle crease lines.
But what's the next step?

Like the instructions say; lift the point and bring it up.
