The Siamese 3x3x3
The Siamese is easy to build. You need to make 1 middle connection piece and two
corners connection pieces.
Material :
 | Two Rubiks Cube 3x3x3 |
| Super Glue |
| Putty (for the corners) |
| Dremel Grinding Stone 8215 (for the edge) |
| From two edge pieces, saw the "L" from one edge and make two groves with a
Grinding Stone on each side. The corner must fit in the grove. |
| Glue "L" to the edge, you may want to sand and polish the edges. But since it
is in the inside it is not really needed. |
| For the Siamese corner you need the two corner of each cube
 | Drill a hole in one corner and lift the cap with a screw driver |
|
| Saw from the other corner the section with the pin.
| And remove 2 mm from the outside, you make the corner segement with a pin |
|
 
| Remove from the first corner a round section where the corner segment will be
placed
| remove from the inside of the corner cubie a bit with a drill, in this spot the pin of
the corner segment must fit |
|
 
| To make the corner section, use the siamese edge piece for fitting |
| It should fit like this, this is also the glue position. Put some putty in the inside of
the corner cubie, slide the corner segmemnt in place and use super glue to glue the parts
together. |
| The corner piece: |
| If you think this is to complicated, this was my first prototype corner. I do not
recommend this way to build, but as a start it will do, just saw two corners in half and
glue them together |
| And well If size does matter, you can also build a siamese from the Gaint 3x3x3 |
| A friend of my builded a keychain version: |
 
 
| Remove two rows of each cube |
| Remove the stickers at the side, glue the cubes only at the middle column, so the middle
slice still rotates.
| So just glue top to bottom of the rows and not the sides |
|
Triple Rubi-X
| This type has 4 connector pieces, the first version was build by Duane Cash, but it could not turn the
middle slices, the later versions where build with slice moves. This puzzle needs 4
connector pieces this is my version of the connectors: |
| The puzzle has 4 the same connector like this: |
| Saw the "L" of an edge |
| Make two groves on the corner on both side with a Grinding Stone on each side. The
corner must fit in the grove. |
| Apply putty is needed on the "L" to fit, fit remove and let the putty dry,
then apply super glue |
| You place the two connecter like this |
| You can make a Siamese cube 2 like this, but this version has no real puzzle challenge
since all slices can turn, you can use almost normal algorithms of the 3x3x3 to solve this
one |
