How do I divide paper(square) into 40?
Can you guys help? I figured how to divide into five but not into forty. I just don't know what to do I know to divide the fifths into eights but apart from that...zilch. I'm trying to make a grid for the dobsonfly.

Re: How do I divide into 40?
Ok, so you divide in fifths all valley folds on one side. One thing you can do then is turn the paper over and pinch what are now mountain folds, bring them to the next fold and crease. That will allow you to divide each fifth in half (so you get tenth). Repeat the process on each tenth division to divide in 20 and then again for 40.

Re: How do I divide into 40?
Thank you! Now I have to figure out how to mark this as a grid.....
Also how should I precrease it? Would I just collapse on the grid once everything is added?

What's the difference between "mark a grid" and "precrease it"? I must confess I can't really picture what you're asking .

Mark a grid: Only pinch the edges
Precrease a grid: Fold through the whole paper
For a beginner who wants to fold the Dobsonfly, I would recommend precreasing, as only marking, adds an unnecessary degree of complexity.

Oh. This confused me because all the reference points......

Re: How do I divide into 40?
As long as you fold neatly, you just need to pay attention to where you make the diagonals. It's as simple as counting how many units each crease crosses.

Finding the reference points to make the grid-read before an
Oh. Thanks....I meant more of the reference points of the areas where there wasn't a full crease, only an part. Well I guess I'll start the testfold.
Pardon me, but wouldn't dividing into 40 add extra creases?
To be exact, the areas I mentioned were the areas that didn't have a full crease line(down the whole cp).

Re: How do I divide paper(square) into 40?
another way to "mark a reference" is just use a pencil on the hidden side. purism aside, i think this method is most exact, particularly if the reference is an odd division (i.e., 17ths, 23rds, etc, etc).
Re: How do I divide paper(square) into 40?
Using an out-of-ink pen to mark a reference without coloring the paper is also convenient.bethnor wrote:another way to "mark a reference" is just use a pencil on the hidden side. purism aside

Re: How do I divide paper(square) into 40?
Also,
Does anyone have tips on dividing any type of grids(specifically 48 and 40, but any grid in general)?
I am finding I can divide into those but cannot make it so it is M,V,M.
Any tips on this or making grids in general?
Any help would be much appreciated.
I found this video:
But the quality isn't the best and it is hard to follow with him using such large paper.

Re: How do I divide paper(square) into 40?
To divide into any grid number (or any proportion, for that matter), you can use the Crossing Diagonals theorem, which is outlined in Robert Lang's paper Origami and Geometric Constructions.
Making a grid where the creases alternate parity is as simple as folding half of the desired grid and turning the paper over before folding the rest of the creases. For a 48 grid, for example, you'd fold 24ths (using thirds), turn the paper over and fold each division in half.

Re: How do I divide paper(square) into 40?
Just what Balto said, with the addition, that if you have a coloured side, you start folding the grid with the coloured side up making valley folds (for 40th that would be dividing in 5, 10, 20) then turn over to the white side and make the remaining divisions as valley folds there.

Re: How do I divide paper(square) into 40?
Balto, the second method you said seems to work. I'll be making the diagonal creases to finish the boxpleating, maybe this afternoon. Still hoping I won't have a 1 inch facehugger......

Re: How do I divide paper(square) into 40?
Gleichner:
1. Divide the paper into fifths. There are different techniques for that. I love the one diagrammed by origami_8: http://www.origami.at/diagrams/Fifths.pdf
2. Divide each of the five bars in half. You'll end up with 10ths.
3. Divide each of the ten bars in half. You'll end up with 20ths.
3. Divide each of the twenty bars in half. You'll end up with 40ths.
That's it .
