I got home today, and decided to tack together a prototype picavet, mostly because I couldn’t visualize how it works.

In case you don’t know what a Picavet is, and it wasn’t clear from my somewhat rambling “demonstration” above, you can surf back to my posting about the Kite Aerial Photography Electronic Resources page, which I used as a basis for my attempt.
Mark, I think the washer is extremal important, at least from what I have read.

I put one together tonight as well. It took about an hour, not counting a hardware store run. Did most of the work while on the phone with Tim.
