PortaDolly® XLDL - Test 1 on Vimeo
It supports a rig up to 10lbs and has 'stepped' rails for various heights. I found this to be far more stable than either a single of double tripod solution. This unit is available in White or Black coated steel tubing. Entire scaffold only weighs 18 Lbs. Assembles in 5 minutes with Philips hand or electric driver . Includes all bolts & wingnuts and mounting bolts for attaching your Gliding/Sliding/ Dolly rail track. Width is currently fixed but can be modified at your weld shop or mine.
Asking $125 + shipping via UPS or FEDEX ground ( TBD )
Must sell by May 15th.
Please PM me for more details.:hv20-smilie72:

can you post a picture of the rig, like everything included?

I can't do that till May 16th. But it's all the necessary parts for putting up the scaffold. That includes:
2, Side 'stair' supports
2, crossbars
All necessary bolts & nuts for set up
2 bolts & nuts for rail attachment.
What is NOT included:
-Camera (obviously)
-The PortaDolly rail system

Here's a quick animation of the rail system in action

UPDATE
I've made a number of interesting observations with respect to the ideal process for using the Drylin system in a simple "indislider" application. I've horribly overworked but there's one last piece that I've solved but need a resource lead for.Since I'm not planning to patent it I may well share it with some partners in this game to see if they can carry the ball for me.
Consider:
- Pulling the platform at a point at center of the platform and at the same level as the rails minimizes friction causing torgue. Indeed, pushing the load at a point higher than rail height invariable cause torque that is incongruent to the line of motion, which in turn results in binding.
- So how to pull with adjustable and controllable force? I installed a really simple friction 'disc brake' on the platform that with the turn of a thumbscrew– allows me to control the speed of the platform's travel along the rail. My last piece was to find a way to apply a repeatable pulling force to 'assist' my hand driven motion.
• Option A- A rubber band attached to the edge of the platform and wrapped over the end of the rail using block, allows for an unlocking of the disc brake and a 90% assisted pulling force that can be reset for numerous takes. A combination of the friction setting on the brake and the pull force of the band, result in smooth and easy motion, with lightweight or heavier loads!
• Option B is yet untested. I want to locate an affordable industrial retractor that has an adjustable load setting in it for more compact and elegant solution. Like I said, I found them in the UK but no response yet from manufacturers.
The beauty of these two options is.... No electricity or cranking of geardrives required. Simple solutions for a simple challenge.
More later,
