Hull shows us his new 14" secondary coil during construction & tells of an interesting new coating product.
We watch a step by step process as Hull assembles a very large primary for his new coil using 5/8" copper pipe. A few tips and techniques are offered to speed the construction of these large primaries.
The old large 10" coil is fired for the last time so that we can reference the performance of the new against the old. This is done just prior to the installation of the new 14" coil system.
Alex Tajnsek, Richard Hull and new member, Dave Sharp, set up, characterize and fire the new coil system. A lot of attention and experimentation is done on optimum coupling of the secondary to the primary. Once again it is seen that all the instruments and static testing is just so much bogus pomp as the theory and testing prove to be way off in the active operation of large coil systems. check it out.
Bill Richards shows us his new repulsion coil. This is an interesting sidebar to all the Tesla work.
Bill and Richard fire the 14" coil. Bill notices something odd and humorous occurring outside the lab. Many, many firings of the big coil are seen in this humorous segment.
Hull details the construction of a larger 18KW+ power control cabinet built in a large steel 19" rack panel cabinet. This will feed the new coil with the extra “juice” it will need as it is improved upon. Again, many runs of the monster are shown with the large white arcs striking everything in sight! One bolt hits the concrete floor and vaporizes a little cement with a whisp of smoke drifting upwards.
Bill shows us his newly completed vacuum tube Tesla coil. We see it fire and get a tour of its construction methods. It lights fluorescent tubes and gas lamps to full brilliance and beyond at impressive distances.
Our still photo section is back as Jeff Mullins shows us a few shots from his massive collection of photos. In this group of shots Jeff tells us the details of his fine coil and shows it firing too. We also see Jeff with Gary Legal. We will be featuring a lot of stills done by Jeff in future, as he has visited and seen a lot of the nation's best known coilers. His massive 300+ photo collection is something to behold. We video taped almost 1.5 hours of his collection with his narration when he visited us in November.
The final word on the use of polystyrene as a dielectric is given by Hull who has exhaustively tested it over two months. We learn that it is almost, but not quite as good as polyethylene (our good old standby). Hull also discusses his aluminum rotary and a recent modification to it that decreases maintenance time and costs.
