Here is my newest project.

Worked on it about 5 hours today total.

The tube is a 3C24
Unshunted MOT
Secondary is wound with Microwave fan wire on a spice container
Primary is wound around part of a hand pump (which is funny because 2 of my other coils use parts of a balloon inflator!)

This is a practice coil for my Micro VTTC coming soon.

The coil will use an external Filament supply

The Resistor is a 3K Ohmite 50 Watt - concerned this isn't enough, Does anyone have a 8-10K the same size?
Will buy / trade

Picture is not great, my camera is in my car which is at the shop, took this with my phone.
Better pictures to come as well as first light!

Newest pictures of the coil I am calling "The Beast"

Kinda like calling a 98 pound guy Bubba.

Spark pix coming soon, as soon as Brett brings another tube as I Fubar'd mine dead

I am pretty excited about this project, first VTTC to work first try (with a wopping 1/8" of breakout). After I found the best Cap I got 1" brushed discharge without doing any tuning.
