TECH: MEETING #1 NOTES

Brad and I had lunch today. Graziano’s. My salad was good, but could’ve used a little more dressing.

Our discussion touched on most of the BEQs, and reshaped things so maybe I have more hurdles for on-site build and fewer hurdles for offsite fabrication.

BEQ#1:

The orbiting pole and door seem decently simple. A fixed pole inside the door, with a pin/ball-bearing unit at the top and bottom.

The center pole/door is a little more complicated, since there need to be two independently rotating entities stacked on top of each other. So do they have a unifying pivot point like a chicken kebab, or are they stacked elements like an Oreo?

BEQ #2

This is possibly becoming linked with BEQ#4. (More on this below).

Brad’s brilliant solve for this is to have the hoop/track be convex and the wheel be concave. I like this! Less possibility to clog/trip on a convex track, and likely easier to fabricate.

BEQ#3

The triangular truss is possibly unnecessary from a structural sense. Cool. Thinking about keeping a decorative element on top, but having it be a half-circle for there to be less obvious directionality, from an aesthetic standpoint.

The joint where the cross arm connects to the orbit pole, however, is greatly a source of concern. Brad is worried about a twisting that could create a pendulum effect (to the wheel). Adding a strut across that corner might be a good solution, but it would interfere with the corner of the central door.

In general, that connecting arm needs stability and isolation. What about putting decorative exterior elements to brace it from the outside? Instead of a support that cuts the corner (90 degrees), could it go outside the corner (270 degrees)? And in three dimensions? Like a cast for a broken bone. (Will sketch this in the coming days).

BEQ#4

Suggested solution: connect the center pole to the ring track with 3-4 spokes, like a wheel.

Sounds great for helping the track keep its shape, and also adding a wide, splayed base for the central pole.

Initial suggestion was to trench and bury the spokes ~6 inches underground, so the combination of width and depth would keep the center pole aloft.

I’m considering adding more spokes (6 total) and/or having them be flat strips on the surface.

Other details:

These parts are sounding way more affordable than I expected.

Brad might be able to help with fabricating these. Ballpark of 1 week for the first unit, 1 day for each subsequent unit.

Wondering about the possibility of fabricating in Victorville. Space could be cheaper there, but it’s not local to prospective crew members. Or doing the wood/metalwork there, and shifting to LA/Bay/Reno for painting.
