You might consider getting a threaded DryLin. Its more expensive but would make it easier to use with servo motor and has option for hand crank. However, keep in mind the threaded rail is more expensive.

Threaded drylin seems to be an option for something like this. Might bear looking into. Seem like Igus has a built in solution for a lot of our questions already.

hmm,, hadn't taken vibration into account. I was just thinking of the pure mechanics of it. It's the one place that where a PULL from a gear in one direction or the other would exert the same force. From the center, a cable can be geared through and propel the platform along in both directions.

Having a mechanism on one end only allows it to pull from that end. You would need another motor on the opposite end to pull it back. Cable is only good for pulling, not pushing.

Vibration is an issue and the height of the platform would have to be raised for something like that to work in any case, so it might actually be a viable option... unless you have a much wider platform.

What's the widest platform Igus carries anyway?

Vibration could be a factor, just trying to brain storm for the best possible outcome, I do like the simplicity of the motor not being attached to the head.

No need for two motors, just attach the string to the opposite end of the head and pull it back the other way. For a vertical desending shot you'd put the power drill in reverse and let gravity pull it down.

I am looking into some kind of surgical tube like they use for sling shots to keep tension on the other end, that way you wouldn't have to put the string on the other end of the head to pull it the other way just put the drill in reverse and let the tension pull it back the opposite way.

I'm still brain stormng on ideas but the main thing for me and my run n' gun shooting style is it needs to be kept very light and simple with a quick set up time.

I see you can get the rails in 4000 mm lenght (12 feet) has anyone used a 12 footer yet?

I'd also like to figure out some way to attach 2 rails together, anyone figure out a way yet? The ends are hollow and I was wondering if they can be studded for a push on type "male / female" fitting that would remain smooth, like they have for the steel track, maybe the 200mm plate would smooth out the transition better than the 100mm plate?

Glad I found this thread I almost spent $1500 on one that would be trashed in no time. Sweet!!!
 
One more thing and sorry if it has been mentioned. Is this rail system smooth if you hang it upside down? A ceiling mounted system for overhead shots type stepup.

I think this might answer your question.....

Yup! Just as I thought. Piece of cake.
The connection solution is:
- use two sets of split connector pins like the type used to connect Manfrotto boom pole sections together, in order to mate two rail sections. I'm kinda sleepy so please request a detailed explanation tomorrow.
- when preparing the hollow rail ends, use fine dremel grinder to take the sharp edge off and then buff it down. You should end up with a very slight champfer. The champfer actually creates more of a gap BUT it's the right kind of gap where the transition from one end to the next is a champfered rather than sharp. As you've discovered, sharp causes the edge to dig into the bearing liners. not nice.

I got mine today and it's awesome. ChipG, I'll be shooting upside down tomorrow to do some crazy low angle stuff. I set it up and the camera is 1/2 inch off the ground. Just have to flip the footage.

Again I say...EXCELLENT! I want to see some of this footage...and some BTS pictures of the set-up. :beer:
 
I got the 10mm smaller version, and it works great with my Canon HF100. I got 760mm length so I can fit it diagonally in a big suitcase. I bolted it to the mounting plate of my Velbon 607, and it can be shaky sometimes because it's a cheap tripod. When I use a cheap monopod for extra support, it works well. I attached a small ball head between the carriage and the camcorder to give extra height and allow for added composition of the shot. Thanks Zaza, and everyone else for your ideas.

Glad it's working for you! Please post some pictures of your "suitcase" model.

Heres a shot of the upsidedown setup. I'll get some footage when we reach the golden hour.

I've attached some shots of my 10mm small version with a ball head.
