I have been using a pendulum suspension for a good while now and, although it’s not the lightest method, it has some advantages over the Picavet.
- tangle free
- no knots to unravel or line to fray
- less cross line swing
- cheap: a set of 4 KDH pulley blocks for a smooth Picavet are eye wateringly dear.
I got an email from a Kapper who has made one and he asked how to hitch it to the line. I started to try and describe how to do this this in words and gave up. What’s needed here are pictures: The pivot bar can fly either way up, I prefer it pointing down as I believe the upwind section of line from the pivot point vibrates less than the down wind section (it’s longer). The most important thing is to make sure the line is not in contact with the bar edge on its exit path. Note that all the nuts on the pivot bar are ‘nyloc’, all its edges have been rubbed smooth. The top bar of the pendulum is M6 threaded to accept the 2 nuts fixing it to the angle plate. It took me a while to get these shots as I find rig launch and recovery are the moments I take my eye off the kite so I waited till I had a good steady flow and was happy the kite was fixed in the sky rather than buffeted about as it has been of late. A good exposition on pendulum suspension by Christian Becot is here.
As Brooks would say:
