yeah....
I'm of two minds about textures. Even if I don't texture something, I do usually unwrap it. Of course, if I add something, that would invalidate the uvmap, but ohwell.
As for rigging.... while using a script to set it up might be nice, I guess I tend to prefer to set these things up myself. And in this case, a bunch of the pistons probably couldn't be made with that script (I don't know for sure, but its my guess given the way some things actually connect). I actually think I know how to do the rigging, now, anyways.

Thanks for the comments! Of course, as I'm in the middle of the unwrap (and then the rig, I guess) there's no visible progress. I think mostly I was looking for reccommendations about the model (Like I said before, I am planning on a number of variants of this).
Thanks.
