Greets!
The link didn't work for me, but I assume you mean this one: http://vikash.info/audio/measurement_clamp/
Anyway, mine wasn't quite so fancy, being a sturdy wooden stand with an inverted 'V' where I could just slide the driver down till it fit, then clamped it.

Thanks GM for completing my link.
I don't think a cable is ideal as it allows the driver to move back and forth. Vikash's clamp keeps the driver fixed in all dimensions and away from reflecting surfaces. His site seemed to be down last night so try it again now. I just did and it came up fine.

Yeah, definitely don't just dangle from a wire to measure T/S.
No, no drawing, I typically just built stuff as needed with usually no more than a few critical dims jotted down on the wood/whatever. It was nothing fancy, just a triangular braced 'H' frame of 2x4s with a couple of cross bars to hold the 'V' frame. I used welder's clamps to hold the driver, but you could just gently screw them to it.
The main advantage of a big, sturdy frame is that you can measure at much higher average power than T/S small signal, which can considerably affect box size/tuning.

I plan on using the method on Rod Elliots site. Everybody here seems to have indicated it is a good method.
I have a function generator and a decent fluke meter, just don't have a solid accurate way of measuring the frequency. The Fluke meter has a frequency measurement on it so I will have to check how accurate that is.
