Well, not if I'm spraypainting parts or so, that's done somewhere else.
But as I mostly make customs from switching existing parts, yes that's where i put them together (though when I'm lazy I sometimes work in the couch too).
The table is often full of parts (even on the floor), but I clean up every day
I often just work through till I've gotten a figure the way I want it, then all the other parts get stored away again.
And yeah, for pics a tripod might help! Never used one sofar, I usually just hold my breath to keep musles & hands steady...
I also like to take shots from a perspective like one is among the klicky-action, then a tripod is not so easy to use. I'm also still trying out how much zoom to use for different distances...
