Small is relative and is not the impression you get from close up. Even a small TC is extremely loud and fearsome.
Nevertheless I chose a scale that gave models of 4 feet high as a compromise so they could wear people clothes, shoes and hardhats.
The other scale factor was the length of spark. I settled on 19 feet or so as trying to fit in 30 feet sparks made the Tesla coil in the picture too small which was really the focus of the shot.
I was not really happy with the final result but with a full day setup and multiple problems the final shot was at 10:30 pm which was not a sociable time. I didn't have the 1/2 hour to correct the problems, reload the lines and reshoot.
And why do this in the first place? Shameless self promotion mostly. I like to have lots of new WOW stuff that is nowhere else on the net. As a result my Tesla site is now up with the best in the world. Just Google for Tesla coil and Tesladownunder is usually 3 and 4 out of 400,000.
I am catching up on my last competitors with similar sites who are both PageRank 6 and I am still 5 as I have been going for a much shorter time.
The thing is that I am an ordinary Aussie bloke with no qualifications who is entirely self taught. Funny how things have turned out really.
