Aerial Cube

Circus/Cyr Wheel, Machining

I just finished another project: the Aerial Cube.

Louise and I saw the cube at a circus show last week, and I thought “Hey, I could make one of those!”, and Louise asked “Can you make me one of those?”. So, here it is!

The cube is made out of 1″ tubing that is 1/8″ thick. I bought it at a local metal place – “Sims Metals”.

I cut 45’s with my little Grizzly horizontal bandsaw:

And drilled+tapped some holes into a piece of steel to create a jig to hold the tubes at 90 degrees:

And then welded two separate squares together:

I then notched the four connecting pieces with a 1″ end mill so they would fit “fairly well”. I then MIG welded all the corners together, holding it together with a ratcheting wrap to keep it square. I then sanded it a bit…which got my hands a little dirty.

What a great project! That cube act was my favorite at the Cirque Dreams show – Louise now just needs to get 3 more friends to work out an act with!
