Instructions on building a Cable Cam for a small camera. A cable cam (or cablecam) allows you to take smooth moving shots, similar to dolly shots, but over uneven terrain. Professional cable cams are remote-controlled, can weigh hundreds (or thousands) of pounds, cost tons, and take hours or days to set up. This design fits in a backpack, was made of stuff I had laying around my house, and takes 15 minutes to set up.

Before you begin, here are a few disclaimers. I have tested this design with a compact point-and-shoot camera. You may need to modify the design or materials to fit your particular model. A small difference in weight or size could disrupt the entire balance, rendering my design unusable. Also, note that the cablecam causes your camera to fly down a rope at relatively high speeds with a jolting stop at the end. I am not responsible for any damage that may occur. I have tested mine for over 75 shots with no mishaps so far, but no guarantees.

Okay, now onto the materials. All PVC and fittings are 3/4

PVC Pipe
4 x 3
2 x 8
1 x 6
1 x 2.25

Fittings
4 x T-fittings
4 x 90 degree elbows
1 x end cap

Hardware
1 x 1/4 by 1 bolt
10 x 1/4 by 1.25 fender washers
2 x pulleys (sorry, no clue what size they are)

Cord/Rope
2 x 18 paracord
2 x 10-foot cords (paracord works here as well)
2 x 50-100 feet cable. Most of the video shot was done using paracord as the cable, but it stretches and is difficult to get taut. I have now replaced it with 5mm static climbing rope. Wire cable may work as well, but I have no experience with that.

Last but not least
2 x bandannas
1 x PVC Camera Mount
1 x camera (obviously)


Knots used in my setup*
Cow Hitch (or Lark's Head)
Reef Knot (commonly called the Square Knot)
Positive Knot http://www.youtube.com/watch?v=3oRZjk...
Lapp Knot
Alpine Butterfly
Versatackle Knot

*I encourage you to look these up separately as I don't spend much time showing how to tie them. Other knots could easily be substituted if you have other favorites.

Because of the complexity of this video, I rushed through quite a bit. But if you have any questions, I'll be glad to answer them.
