cool the thing l made is working out pretty nice --- trying to fine tune the falling rate of the rig is the hard part -- and for the rig l made, taking the pulleys off so l can remove the whole thing from the line is a little tricky trail-side. you might want to add weight so it doesn't rock from side to side

just thinking --- l think one large pulley might be a great option as well as two smaller pulleys ----with mine (a 2 pulley design), as you pull the cage up the zine line, you see the cage and how it tilts up along with the slope of the zip line --- using one large pulley, the body of the cage will always remain in a straight vertical line. (aka the camera will remain level) l have another prototype l will dismantle and rebuilt as a single pulley design. ----- using a design similar to you PVC pipe design, you might be able to mount on of those GoPro "tri pod" mounts at the bottom..... hmmm, l think l could ever design one with a tri-pod mount at the top of the pulley, using a U shape bracket that wraps over the pulley. that would be dope --- rollin' two Go-Pro at the same time -- one facing foward, one facing backward (filming multiple riders, riding at the same time).

thanks you amigo.

my best version to date from my bag of tricks ---

dual pulley set up the way they are, in-line with a small gap between the two allows me to move it from one zip line to the next without any fuss --- just turn the carriage 90o and slip the cable through the two pulleys, rest it on the line and taa-daa. zip line ready.

SIDE NOTE -- some other guys are trying to build similar things, making them as light as possible --- personally, l think a little added weight is key -- at least with the type of zip line l'm using it is --- the added weight helps keep the rocking motion down and helps with the falling/rolling speed. gravity fed, light weight units slow down too quickly.

here's some zip line testing with the new rig l made small changes to---

gotta tweak it just a tad but, it's really easy to set up.

there's a quick wobble each time you release the unit but the wobble goes away within about 6 feet of rolling.

thanks.videos came out awesome.

2nd, revised version ---

aside from the GoPro and pulleys, it's 100% left-over bike parts

That looks awesome!! post how it goes and i might have to nab your design !!!

Nice, now you need cable and a steep hill...You riding yet?

nomorepb (Dec 21, 2012 at 8:38)

Pv testing tomorrow.wnd I can't ride til the end of march.

SoCalMX (Dec 21, 2012 at 8:42)

What time will you be there?

nomorepb (Dec 21, 2012 at 8:50)

afternoon..about 1 or 2 pm

nomorepb (Dec 26, 2012 at 16:00)

looks very nice but i think it will swing too much.i do prefer with two wheels.

PedalShopLLC (Dec 26, 2012 at 16:21)

yeah --- we'll see how it works. test run in the basement seems ok so far. if swings too much, l have plan B ready with a modified two pulley design which will actually be the easiest model to use out of the three versions l have made.

nomorepb (Dec 26, 2012 at 16:24)

cool..plan B sound better.wait for some videos..

PedalShopLLC (Dec 26, 2012 at 16:36)

the flaw with the two pulley design, the camera doesn't stay level --- as the slope of the cable changes, the camera points up/down depending on where it is. the lines l have strung up are pretty long so at the two ends, there's a fair amount of rise (compered to the lowest point in the middle). with one pulley, the camera will always stay level no matter where it is along the zip line.

there's a camp near us l went to that has zip lines for people to ride --- they only use one pulley.

Plan B, l do plan on having the two pulley pretty close to each other, far enough apart so it's easy to mount the pulleys on the cable.

PedalShopLLC (Dec 26, 2012 at 16:39)

how do you put your cage on the zip line?

do you have to remove the pulleys?

my first version, the pulleys are set up with cotter pins -- just remove the cotter pin and the pulley pulled out allows you to set it up on the cable -- it's a little tricky when out in the elements.

i saw a video and like it www.youtube.com/watch?feature=player_embedded&v=refzOJLr4ww!
