CD rocket...

Post by Bob » Tue, 28 Apr 1998 04:00:00



I'm sure that at some point I read on here about a rocket made from old CD's.
I checked DejaNews but if there was a posting it's been lost in the 1700 postings
about Cd. So if I'm right in thinking someone has built a rocket out of these things
has anyone got any info on it, or can anyone point me in the right direction of a
website?

Thanks,

Bob.

It's pretty common to see someone cut fins out of a junk CD. They make fine
fins, but gluing can be tough. One of my latest creations uses an AOL CD as
a centering ring for the bottom of a food container. You can read the AOL
stuf right thru the clear sundae lid.

Hey Bob,
Would you like me to start shipping you my garbage? I'm sure you would
find some very interesting items with which to apply your creativity.
Let's see, M powered range, J powered blender, L powered BBQ grill....

Clear sundae lid??? Club must've stopped at Dairy Qeen after the last launch
eh? :-) LOL

I did a rocket designed for for the FSI E5 motor that uses CD material for
fins (uses about 1/3 of a CD for each fin.)  Other than that, it looks like
an egglofter (long tappered body and paper-mache' nosecone molded from an
Apogee egglofter cone.)   I've got a bunch of small trapazoid fins cut from
CDs as well, waiting for a suitable rocket, and some CD-Rs that didn't work
(GOLD!) waiting to be cut.

They're not really as tough as I'd like - sort of brittle.

I have a near-infinite source of disposed CDs that I'd be happy to mail to
anyone for the price of postage.  cisco publishes a new documentation CD
every month or so, and the old ones are then obsolete and get "recycled."

How did you cut them? I've been wondering if my jigsaw will do the job orif it's a bit fast and will shatter them. I don't have a fret saw, so it
might be
a good time to go and buy one...

How many did you use for each fin? Just the one or two stuck together?

We're having an office clear out and I've got a few hundred Microsoft CD ROM's
so I'm looking forward to destroying them, so no one can get the software on them...

    >>How did you cut them?

Many passes with a knife, held against a straight edge.  A real pain.

Just one.  I think gluing two back-to-back with a flexible glue (hot melt,
double sided tape, contact cement?) would probably help a lot, not to
mention that it would remove the "need" to remove the printing with paint
remover (which I did for some of them), or give you (rather fragile) gold on
both sides with CD-R.) (did you know that you can essentially WASH off the
gold film from a CD-R with hot water?  It leaves a greenish-tinged clear
disk (some of the green dye washes off too.)

A microwave oven will put a neat-looking "crackle" pattern in a CD...

CDs also melt nicely into a formable PolyCarbonate film in a moderate oven.
It should be possible to position on over a greased mold and come up with
some interesting effects...

Thank you, no. For the most part, I've got plenty of my own garbage. Ask any
NIRA member who'se ever come to one of the building sessions in my ba***t.

But I could use a few more AOL floppies. I occasionally get asked to show
folks around our data center at work, and while folks these days can
comprehend a megabyte, they get lost when I show them 9 GB drives, or tell
them I've got over 3 terabytes of storage. So I've been building a gigabyte
to put in the data center. A gigabyte is 695 floppies stacked up. That would
be about floor to ceiling in an average office. But I want them to all be
AOL floppies. Everyone gets them, and 99% of them probably get tossed out.
So far I've got about 200. Contributions are welcome :-)

Yet another interesting project.... Hmmm. I sell computers, and that might
be a nifty floor display to give people an idea of what a GB is. Maybe I'll
start saving those floppies too. :-)
