3-axes slanted notches

[rolly_wood]

.... that is notches which, in a rectangular prism piece, have their surfaces (bottom and lateral sides) parallel to any of the external surfaces of the piece. To realize these notches, the piece must be oriented in space, slanted with respect to all the 3 planes: namely the working plane, the fence and the perpendicular to these ones.
This is rather challenging as , you know, rotations do not commute that is the right order of application of the rotation is mandatory.
Master of this is Philippe Dubois. Many of his puzzles are made in this way. At a first sight one could think that are those which appear more complicated (eg pendo90) but it is not always the case (pendo90 is 2-axes slanted). One of the brain teasing 3-axes slanted is unnamed dubois #1 (http://www.puzzleworld.org/Puzzleworld/puz/img/lg/unnamed_dubois_1_1.jpg).
I needed a lot of time to understand its secrets but now I am on the right way
You would say: it is just copying. Well it is, but, for my capabilities, it is difficult anyway and I am rather satisifed when notches and pieces match as they would have to do.

Er, I think everyone is dumbfounded Roly ( ie dunnowhattosay)

Have you build further to these 6 sticks, like Dubois?

Show us, show us, you have our attention

End result is a beautiful Geometric sculpture, and the anglular cuts,,,,wooooeee

[Canuck]

Yes, not really in my 'wheelhouse' but quite anxious to see a finished puzzle from all your hard work...great job Rolly!

not yet but these six demontrate that angle values are correct. Sometimes I am happy enough about it and finiished puzzles is never biult. This time...dunno
I will think to some variation probably a more open strucure and maybe beveled tips...

thank you John this time it did not come out at the first tentative.. but at the end math won

 but at the end math won 

Who is this 'Math' character you speak of  

You know it's funny because with my two boys, one seems to be very keen with 'math' but the other is 'not so much'!

Perfect: the 'math' one can design and the other one will realize.
John the family future as puzzlemakers is clean

Wow Rolly you are one smart thinker!  I am only able to cut 90 and 45 degree cuts, anything off of those and I am lost!  "copying" this puzzle is a feat to be applauded!  Amazing!!!

Hey Roly, dumb question

Shouldn't you be using penta sticks to make this penta geometric sculpture

Another Roly creation, so COOL!

Silly me. what do I know about maths and angles, I just pull teeth

Back to the drawing board for you

When you are making this while we are away at IPP, make 2

Make that 3,4,5,6,,,,,,, and we like fancy woods

I second that!

hmmm it is not a dumb question but: the sticks are along the edges of a 12hedron and there the dihedral angle is 116.5. Then if one uses a golden rhombus as section (as vertIgon) this will resemble more the plolyhedron... I will think about it .... thank you..
You are joking but I am looking for a design which I can produce in several copies in a reasonable time, you know I am very slow. Of course to send to my friends here at Eagle to whom I am in an overwhelming debt

[LEAP]

Man when ever I come here it seems like I'm reading things in another language! That looks like a feat to be proud of Rolly, almost like one of those optical illusions of impossible shapes.

Rolly, you never cease to amaze me.  You tackle one tough nut after another.  For your next puzzle, why not try something simple that all of us can follow?

Good luck on your current endeavor, looks like you're off to a great start!!

More pictures...when you get done.

[rolly_wood]

thank you Peter, Phil and Mark, you exaggerate ... 

I will think to some variation probably a more open structure and maybe beveled tips...

something like that, it is different enough from unnamed #1?

[cubefan]

Hi Rolly

I can only say: bravo, unbelievable

great work

make it

best regards

I agree with Bernhard!!
