Step 2: This Crate

This crate was built to carry three large aluminum I-beams and eight carbon fiber spars.  The top part of the crate held the aluminum, and the bottom held the spars.

The two compartments are separated by a plywood "floor" that lifts up.  The floor has circular thumb-holes drilled out (with smooth walls, no splinters) allowing a human to lift the floor anytime.  The floor is supported on its edges by a molding-like feature of 1x lumber screwed onto the wall of the crate, just below.

It slots down over the vertical brace lumber, and is cut to have enough room to slide by even at a ~15° angle -- which is exactly the amount of tolerance required.

Shown here in the first image is the crate, before packing, and its future lid (to be screwed on) leaning on the side.
<p>A good enclosure has a satisfaction all it's own, but how much more so when you get to put part of such a grand instrument inside of it! Was this telescope an optical telescope or some fancy microwave gizmo for detecting B-mode polarization?</p>
It's always nice to realize that others also pay attention to the details, both ART for taking the time to fabricate the case, and you for noticing.
Wow! That's a lot of science! ;-)
Very nicely put together ! (so to speak).
... and the mark of true genius lies in finding the right people to do the job. Of course it makes sense to have the theatre company pack your radio telescope.
1. Would Tim Anderson roll over on his kon-tiki because this shipping crate might end up as landfill on the tundra or drift out with the garbage tide? Sure, it may be good quality formaldahyde-free plywood but you could have used some eco-friendly packing fill. &nbsp;I would have printed some cut-out patterns for furniture on the crate so it would get reused, at least not for firewood, it does get &nbsp;cold there.<br> 2. Why not let the engineering students have a crack at designing a shipping container so that the contents would survive a drop off a ten-story building...wait, that's the other school.<br> 3. How much does FEDEX charge to ship that?<br> <br> Nice job.<br> <br>
Another interesting thing to watch is set-up or tear-down of a high-tech trade show floor. Picture 100+ vendors, each with some sort of fancy &quot;booth&quot; (some two stories tall) and all sorts of relatively delicate high-tech gadgetry (nothing quite so delicate or pricey as this telescope, of course.) And it all has to go up and come down in about 8 hours.<br>
Or professional theater troops with big traveling shows. If you've ever been to such a show you know that it seems as if that stage has been there forever. Little do most know but that stage was contructed from scratch using modular stage elements by techies like myself. <br><br>Time from the show coming in with the semi's full of stuff to the end of set-up including lights and sound checks, aprox 4 hours.<br><br>Tearing it down and packing it up again - aprox 2 or 3 hours.<br><br>Show itself - 90 minutes.
Oh, and for anyone who cares...here's are some publications from the <a href="http://www.google.com/#sclient=psy&hl=en&q=BICEP+radio+telescope">BICEP telescope</a>:<br><br><a href="http://arxiv.org/abs/astro-ph/0606278">An overview of BICEP</a> (conference proceeding)<br><br><a href="http://iopscience.iop.org/0004-637X/711/2/1141">BICEP's performance envelope for CMB polarimetry</a> (published in Ap.J.)<br><br><a href="http://arxiv.org/abs/0906.1181">BICEP measurement of the CMB polarized power spectrum</a> (published in Ap.J.)<br><br>...And it's pretty cool that the <b>second hit</b> from Google is this very Instructable!
Wait a sec....so, are you a post-doc in Harvard Astrophysics, or a member of ART?!? Either way, this is an absolutely awesome writeup, showing some of the &quot;behind the scenes&quot; (okay, should I really say &quot;backstage&quot;?) stuff that goes into making real science work. Rated and featured, because Science is Cool.
