Based on an original design by Christian Becot, as used by Christophe Gaston, I have been using this for 4 years now. Over that time I have reduced the size of the pendulum, halved the beam length and used a nylon boat pennant toggle for the fixture to the line.
In this iteration I have shortened the first joint to get it to fit in the camera case and shaved off a bit more weight from the web of the beam.A few of the bits are canabalised off earlier versions hence the wear marks at the pivot.It will fit in the box with the rig and the camera so I won’t run the risk of leaving it behind now!
Beam length is: 24cm. Pedulum length is: 56cm
Material: Aluminium tube 6mm and 9mm OD, die cut 6mm bar and 20mm ‘L’ section. The semi-rigid joints are from thermoplastic brake tubing fixed with 4mm snap rivets.
The pendulum uses a steel ‘R’ clip to attach to the rig post.
The flexible joints are a boon when folding it up and also absorbing ‘dump bumps’ when recovering the rig in a lull, not something I rely on mind, but it happens from time to time!
Sky hook launched in biting cold NEasterly….And the pendulum works fine as the kite buckets about in an on/off Bft 3-5. I keep the line well clear of the edges of the beam when fastening it to the toggle hence the slightly odd alignment with the flying line. Here’s my test shot:
Now I can hear KAPers asking ‘why do you use a pendulum over a Picavet as 80g is a lot compared to my tin cross and a ball of string! In all my experiments with the Picavet I have had 2 consistent results: huge latteral swinging of the rig that takes a long time to dissipate and a tendency for the Picavet lines to jamb and tangle (I have had the thing wrap itself around the flying line) if you add to that the fear of line wear in the pulley system (particularly with the 1.3kg DSLR rig) you can see why I opt for a more robust method. I reserve the Picavet for a pocketKAP rig which I can fling in the air and hope for the best when I’m too wind shy to risk anything else.
