Winding 14.3 by 10 cm, arc 193 cm: 13.6 times the secondary by his own reckoning, on a modified UD2.7c. One of the nine on the records wall.
A later thread (ferroceriumTc’s QCW build, Sep 2026) credits him directly for “IGBT gate driver pcbs” and a buck-converter design that other coilers have since built from. That kind of work does not show up on a records wall built around arc length.
