Burning Man 2013 Honorarium Project / Impossible Triangle Now Made Possible
EmailRSS

Tubes.

Surly and Andrew aka “Shop Monkey” have started banging out some tubes.

Cube edges with 0.083″ wall are in the foreground, 0.12″ wall is in the background, only one of which has been prepped.

The triangle requires four types of beams on the cubes, fourteen types of straight beam on the arm and three types of bent beam.   All of the straight beams come in mirrored pairs except the thin and thick cube edges.  Here’s how the arm breaks down:

The beams need to get  a 1.5″ diameter notch where they meet the bent sections.  The other cuts are miters.  The result is a lot of fussy little cuts:

Each beam has 2-4 miters and notches per end, creating 28 different unique types of ends for the beams in the arm alone.  Each cut had three degrees of freedom, so that’s a lot of information to communicate.  The solution?  Stickers!

Now if we can only figure out how to feed the sticker paper the right way into the printer…
