Well I think an easier thing would to buy a spool of metal cable and then get a come-along I think it's called. It's like a winch operated by a lever that you crank. You just hook it up to the cable and a tree anf with the other end of the cable to another tree as tight as you can. Then you crank the winch to make it tighter. Then put a harness on and hook it up to the cable with a pulley and off you go, full manuiverability with the camera and it's fun! Hang some towels on the end of the line and have your friend put some gloves on and pull a rope(that is directly attached to you) to slow you down.
correct, and thats exactly what me and my friends are doing

actually i just thought of it if you just attach a figure 8 descender used for rappelling to you and run a rope from the top through the descender you could just use that as a brake which can be done easly with one hand so you can get shots where you may need to pause in one spot for

Better idea, but how are you planning to tension the cable? You need literally tonnes of force to keep it tight if a person will be going down it. Hell, I need about 150kg of force to tighten my rope for a 3kg cable cam on long distances...

how about if you do something to the rope at the point where you'd want to slow down so the unit rolls slower at that point? not exactly sure how that could be done though...

perhaps you could control it by hand with a fishing line or something attached to the unit. you could let it go for a while and then when you want it to stop just pull the trigger on the reel to stop the line, and then let go when you want it to roll again.

i would tension the cable with a come-along

i dont think that would work very well just because the braking would be very sudden but if you are just gunna use a little cart that i would just use another rope or twine or something not fishing line

yeah, i considered that. maybe just a separate pulley on one end of the cable and attached to the cam that you can just loosen off by hand.

hey i have worked in the film industry for seven years on cablecam rigs. Everything from custom high budget to low budget. We mostly do 3D rigs now but have I set up over a hunfred A-B with elevators/tie back. I have just gotten way into biking past couple years and spend my summers in Squamish, BC. If any one wants some help or info drop me a note as I am keen to see what people are up to. You can either contact me on pinkbike or on my email. rmitrovich@hotmail.com
Cheers, Russel.

What sort of knot should u use around the tree? I think i'll get a rchet strap as WOOWOO said in another thread, cos that sounds like a good idea. And anyone got any good braking systems?

This is the one I made, planing to add a up and down tilt mechanism,

Any ideas on how to make it more stable, still a bit shakey?Unsecure image, only https images allowed: http://i882.photobucket.com/albums/ac22/Peterwest94/DSC03333.jpg

tighten that rope up so much it nearly breaks, are there any leaves near the rope if there are get rid of 'em

Unisaur, you want to use fixed pulleys with a cable cam. Those loose pulleys won't be very stable and will start vibrating when the rig moves down the line.

Great rigs you all, I'm in a process of building my own, I'll report here with the results!
