Through the Looking Glass – DONE!

 

Finito.

After a long week of cutting, grinding, welding, and bolting – the convex hexes are all attached to Through the Looking Glass. That means that I’m finally finished – the only parts still without a home are those for the base, and they need to stay off until the piece is installed. Heavy sigh of satisfaction; I really like this thing.

Below are some more action shots, showing the process for attaching the convex hexes. Those in the “field” and along the inner edge are a piece of cake; the ones that follow along the elliptical edge each have to be cut to shape and a custom rig for bolting them on has to be fabricated. I was able to get about 8 on per 8 hour day. Very labor-intensive and a bit hard on my hairline.

Now I just need to get the thing to Little Rock. Are you guys ready yet?

Split Infinitive, re-worked.

I designed this piece way back when Sketch-Up was my main software for modeling. I was pretty happy with the way it turned out, but over the course of its fabrication the first time around, I discovered a pile of things that could have been done better to yield a smoother and less laborious process. Chief among the changes was making the thing symmetrical vertically, which enabled me to eliminate two entire butt joints in the sheet metal, which means significantly less grinding – which means a much happier Humble Narrator. I used my original Sketch-Up model, importing it into Rhino so I could have a starting place for the geometry:

Mesh edges from Sketch-Up.

After a whole bunch of mucking about and snapping new construction curves to that stuff, I was able to get a cleaner version that had the added benefits of being easier to fab AND better aesthetics.

Fixed up in Rhino – and natively on my Mac in the Rhino Beta for OSX.

From there, I used Rhino’s Unroll command and some patience to arrive at a 2d pattern, ready to send off to the laser for cutting out of stainless steel.

The Gallery below shows some of the initial stages of the assembly. I made a gumby little wooden jig to bend the tight inside curves; the outside curves bend against the “sides”, so don’t need to be pre-rolled.

I LOVED the piece with just the sanded metal surface, but this one is actually sold, and the client wanted a yellow powder coat. Yellow? :– {

Turns out, yellow is SPECTACULAR on this thing. The first image above shows the piece fresh from the powder coater, followed by some shots of the edges being filed back to reveal the shiny stainless underneath. I love the way this iteration came out. Hopefully my clients feel the same – shipped it off a while ago and wondering what they think.

Dutch angle with Japanese maple. Artsiness.

PS: I posted quite bit about the first iteration. Some linkage:

Here, here, over there, and here, too.
