Geometry - Manta Ray shape

[crystallographic]

I arranged this shape to look like a Manta Ray.

With nine inches of shape it took a while to get there.

I think that form is known as a hyperbolic paraboloid.

Nice work Kent. What is it ? Art or functional thing? What kind of material is that?

Whew! Thanks Tom.
I was reluctant to post it as a parabolic hyperboloid....
(it is actually a helix, re-arranged.)

Hi Kent,

Whatcha doin' with those perforated pieces?

Hey guys, I've seen how he made these. It's even more impressive that he did it by himself. He's a pretty crafty 'rascal'.

Goes beyond "crafty" (About which you're no slouch - seeing your "restoration")



I was in his shop while he was working on this stair project.



Understood what he was doing - cuz you could see other sections stacked to the side.


What I didn't ken was his particular approach, the "strategy" so to speak, as to how he approached the task.


So I asked the question. (Oooops!)



I think he thought I didn't get the concept as his reply was perceived rather "pointed" - shall we say - Fair conclusion on his part for a poorly phrased question.


So, did the better thing, with his consent allowing me to watch his progress.


I've posted before that his knowledge and skill levels are a quantum level above most. This incident was further proof.


Motivates me to pay attention to the task and the fact that metalshaping can be a continuous learning task, not just busy work.



FWIW

.... and with humble apologies to any visitors who came to the shop expecting kind open-hearted lengthy explanations of twisted surface developments, and instead received short-tempered irritable crotchety old mastodon.

Making spherical shapes and sections of spheres for masks and lighting - stuck in architecture, currently.

Long live the short-tempered irritable crotchety old mastodons, there's damn few of us left.
