Larger bipolar Tesla coil, with pressurized spark gap

This is footage of my newest bipolar Tesla coil. The secondary is 19 inches of 23 gauge heavy build magnet wire on a 5 inch cardboard form. The primary consists of 12 turns of stranded 12 gauge wire on an 8 inch cardboard form. The frame is 3/4 inch PVC tubing. Power is supplied by a 7,500 volt Allanson neon sign transformer. The capacitor bank is 18 Leyden jars of my own design, total about 8 nF. The spark gap is a single gap pressurized by a small vacuum cleaner. Arc length in this video is 10 inches. Max arc length obtained so far, 14 inches.

Thanks. It's been easy to scale up or down the tubing size to accommodate different sized coils.

Really like the PVC base. Nice arrangement.
