Cubic trefoil

[mklotz]

My latest project, a trefoil knot,

(described more fully here: https://en.wikipedia.org/wiki/Trefoil_knot )

done using only linear segments and right angles, hence a cubic trefoil.

Deciding how to cut the 15 pieces was the easy part although they are not all the same. The real test comes during assembly. Each of the glued miter joints has to be 90 degrees and coplanar. Accomplishing this involved using a purpose-made right angle former with the assembly held in a jeweler's vise to guarantee a coplanar join.

Even with this care and waiting 12 hours for each joint to dry, error build-up was inevitable. The last joint required some fine-tuning with a sanding wand to make it fit.

It was a fun project but I don't recommend it if you are easily frustrated.

Next project will be the infinity cube...

Not as visually interesting but a lot easier to make.
