Are those cut-outs in the legs the counter-rotating fans? I though about
it since your last post and thought you might put in no-tar baffles.

Yes they are, I was looking for a not too bad place to put them...it is
the only place I found...
Sorry, but I don't understand the second sentence...what are no-tar
baffles ? (in french if possible...)

No-Tar, "No Tail Rotor" helicopters use a variety of methods to battle
counter-rotation while maintaining directional control.

Didn't they try some helicopter designs without tail rotors at
all, but posessed two main rotors going opposite directions?

I like.
Reminds me of a three legged animation (Rune?) I saw on p.b.a
the short time I visited (a bad idea with my slow modem).

There are some helicopters built using that concept, like the russian
Ka-50 Hokum combat helicopter. It has many advantages over the
traditional approach.

These are funky! :) I dig 'em.
But what I really want to know is how you did the [drill]? I don't have much
time to play with Pov-ray these days, but I had recently been trying to make a
realistic wood screw, and couldn't figure out how to do the 'screw' part.
Thanks!

here, the drill is:
// the values of the various radius may be wrong, it's a freestyle writing
difference {
cylinder {<0.0, 0.0, 0.0>, <10.0, 0.0, 0.0>, 0.75}
blob {
threshold 0.6
#local nbS = 500; // nb of sphere for precision
#local nbT = 10; // nb of turns
#local ii = 0;
#while (ii < nbS)
sphere{<0.0, 1.0, 0.0>, 0.4, 1.0 translate 10.0*(ii / nbS)*x rotate
nbT*360.0*(ii / nbS)*x}
#local ii = ii + 1;
#end
}
}
David.
