One thing I'd like to try is making a ringed planet. I'd toyed with
using a blank CD-R -- cutting the planet in half and gluing the CD-R in
the middle, leaving a nice shiny ring around the outside. What else could we
use?
On a related note, I'm scratchbuilding a Halo/Ringworld right now, using
wooden cross-stitch hoops. Should turn out to be interesting, at least.

I LOVE this! I just wish I'd kept the last bad blank we got here at work; the
CD doesn't get the shiny layer, just a clear disk. I'd have to try scratches
to indicate thin rings, even twisted ones!

Don't those usually have metal clamps at the overlaps? Sounds like a road trip
to Hobby Lobby! Hmm... mounting on bases should be interesting...
Thanks!

In Dirtside scale... About the size of Detroit
Stargrunt scale... About the size of Asia
Hope you have a few long weekends.....;-)
Is that the One True(TM) Stargrunt Scale or that "other" Stargrunt Scale.

Smashing figures again, it's down to between 4-5 miles in diameter, well
within Detroit. At a common FT scale, that is.
Dirtside...? *whew*

Perhaps the foil could be removed from a blank CD-R in rings, if
it was scored around first with a compass point.

Not familiar with that; in a sense, the Ringworld orbited 'as a planet did',
but I'm not sure how you mean it in Masaq. Is it a flat piece facing the sun,
in orbit? If so, how does it simulate gravity?
Oh, and I'm curious as to how it was unfortunate.

They provide a much better mass:area ratio than planets without being as mind
boggling huge as rings.
The physics as presented is okay, although the engineering is left as an
exercise for future generations (much like with rings).
One neat feature for DS2/SG2 players is that the "gravity" is
centrifiugal and hance anti-grav devices don't work (see 'Consider
Phlebas' for a messy example). So you have very high tech armies with no grav
vehicles.

The Culture (eg the West) has interfered disastrously and unnecessarily with a
less liberal, more religious space culture plunging it into bloody civil war.
Divinely appointed vengeance arrives on Masaq' Orbital in the form of a
suicidal terrorist intending to destroy it. The novel is not unsympathetic to
the terrorist.
You might do better to colour (paint maybe, not sure) the clear plastic
non-cd that tends to come at the top of a pack of CDrs. This would allow
you to have a gap between planet and ring. Though a CD would give a nice
shiney ring.

Hi Andreas,
A ringed planet from CD-Rs - good thought!
I toyed with the idea of doing a ring for one of my 'hemisphere' gas giants. I
wanted to do it tilted off the 'plane of the elliptic' and had been
thinking of clear plastic sheat cut in a 'U'-shape. Ideally, the
planetary hemisphere would sit on a base and the ring would also be attached
to the base, with a gap between it and the surface of the planet. Dust the
ring with sand on PVA and then dry brush in shades of grey and white.
Well, that was the plan. Maybe next planet:)
Oh, re my comment about messy polystyrene. Lacking a hot wire cutter, in the
past I have tended to use a steak knife and sandpaper when modeling in
polystyrene (islands and reefs, etc, for Nap Naval). Effective, but you do end
up with your personal snow storm that tends to adhere to things at random due
to the static charge.:)
Regards
David

I picked up my hot wire cutter from Wal-Mart for under $5 US. I can
only
hope the all-consuming Wally-World has not made it there yet but you
should be able to get one inexpensively. If not there are plans on the net for
making one. The main ingredients are nichrome(sp?) wire and a power supply.
I picked mine up at Michael's. In essence it is 2 D cells and a
ni-chrome
wire.

I assumed you were talking Wonder Cutter. That's a VERY thin wire. The more
expensive sets tend to have thicker, stronger wire.
You can do fine things with a Wonder Cutter, just have to have more
patience than I, or you'll snap the wire, at a buck or two a crack. ;->=
On the other hand, my OOP Gobi's won't break, but if I rush 'em, they just
make that many more strings and build up glops of melted PS.
