Here is my plan,
Using mostly machinist parts which are already made to interface... er, to fit together (sorry, messing with too many computer programs lately).
Ok, to begin with, the whole concept of stopmotion depends on absolute stability, unlike the world of still photography or video, where a little camera movement is no big deal. I know from experience that those lightweight aluminum folding tripods are no good... even if you duct tape them to the floor and sandbag the hell out of them, a slight bump means an earthquake in your film. So I want something heavy and solid. I decided on a drill press column. It's ideal... aside from already weighing a ton, it's got a flat base where you can pile sandbags or concrete blocks if you want. Probably no need though.

The beautiful thing about using a drill press column is the tilting table... it's made so you can adjust the height and the angle however you want. I thought about maybe using the height adjustment crank to handle vertical camera moves, but it's not stable enough for that, I don't know, maybe some of the really expensive ones are, but I'm on a pretty tight budget, which is why I'm using machine shop fixtures for this in the first place... you can buy custom made dollies but they're not cheap folks! Ideally I would use a floor model press, but they're too heavy to ship except for truck freight, and I don't want to go that route, so I'll either just pull the top assembly off my bench press or buy one used on ebay. Actually the thing to do would be to get a better press than the one I'm using now and designate my current one as a camera stand. Using a bench model means I need to have a table under it, but that adds even more weight and solidity if I bolt it down.

Next comes a machinist's cross slide table, to handle front/back and side-to-side movement. I already bought one of these on ebay... a $200 model that I picked up for $75. Travel is 11" by 7&1/2"... so it's not enough for those really crazy Nightmare Before Christmas truck shots all the way across the set, but it'll give me some nice movement. And here's what I love about this... it's already made to attatch to the drill press table! A couple of T bolts and good to go. I already have ideas about using a set of drawer slides and some allthread to make a longer slide, but that's definitely a future project.

On top of that, for the vertical moves, I'm using a lab jack. It's essentially just a scissors jack, like the kind you might have under the spare tire in your trunk, except the top platform is a nice flat 6" square that's just right for my geared head to sit on. The best price I could scrounge up on these was about $60. If you do a web search there are quite a few science lab suppliers that carry them, and they're all basically the exact same model, except for a few top-end ones that are super expensive. You don't need the stainless steel version (which is more expensive) unless you plan on doing your stopmotion outdoors in the rain, and I certainly don't!

Ok, with all this sliding and lifting going on, you'll need to be able to pan and tilt to keep the camera aimed where you want. For that I opted for a Manfrotto Geared Head 410 jr... their smallest and cheapest one. It'll run ya about $150. That is already in my greedy little hands, and as soon as the rest of it comes in I'll try to fit it all together and take some pics.
Simple and relatively inexpensive... just the way I like it! For under $300, I have a complete camera movement system (I don't know of a name for it really... technically it's not a dolly, and it's not really motion control. Just a camera mover.)
Ok, here's the setup...
as it was briefly:
This is the way I originally envisioned it, with the lab jack.
...But I found the lab jack wasn't as stable as I had hoped. There's a little jiggle as it tracks up or down. So I hit ebay and bought an RV levelling scissor jack (which only cost me a cool twenty bucks, as opposed to 60 for the lab jack). Wow, this thing is HUGE!! The real beauty of it is, not only is the vertical tracking a good deal smoother than the lab jack (not perfect, but pretty darn good), but it has twice the range! This monster cranks 20 inches into the sky!
It's a lot like a scissor jack for a car, but with one key difference (besides the sheer staggering SIZE!): The top consits of two horizontal plates with mounting holes in them. The ones for cars are usually made to hook onto the frame, and would require modification to mount the geared head onto. I got incredibly lucky, this jack seems to have been made to fit... the mounting holes in the base are exactly the right size to accept my t-slot bolts. I think the animation gods were smiling on me this day! The next picture clearly shows the configuration of these mounting plates:
The little c-clamp is what I'm using for a handle to crank it up or down.
...and here's a cool deep perspective shot, just because I felt like it!
I'm going to make one simple modification to it. As you can see the way it is now, the camera is pretty far from the table (unless I turn it sideways). I plan to get a length of aluminum channel stock and bolt it to the mounting plate, where the geared head currently sits, extending past the end of the jack when it's fully collapsed. Then I'll mount the geared head underneath the channel stock, upside-down to allow the camera closer access to the animation table. That will put it at the perfect height for those low level shots and allow unobstructed downward view from any height. Luckily, the camera has top mounting holes built in.
Well, I think I've settled on a name for this bizarre contraption... I'm calling it the camerajack. Well, sometimes I just call it the monstrosity...
UPDATE

Rather than buy a length of aluminum channel stock I ended up just using a piece of red oak, which is a very hard wood. I had to attatch a piece of steel plate to the end of it, bent in such a way that it won't interfere with the swivel action of the geared head. Now I have a camera crane system, and in a few days I'll have my first two lenses and a power supply!
