Here's the dimensions and inductances for the primary. TT-42 primary: I.D. = 6 1/4" tap (turns) diameter (inches) uH 14.5 11 3/16 58.2 15.5 11 1/2 66.0 16.5 11 7/8 75.1 17.5 12 3/16 84.7 18.5 12 1/2 95.1 Note, this primary is difficult to tap because of the insulated wire, so I only tapped at 1 turn intervals. I didn't try partial-turn tap points for these or previous tests I also did another test. I tapped the primary at 14.5 turns with the 6" x 24" toroid, and I got racing sparks about 1" from the top of the winding, and also at about 1" or 2" from the bottom. These were intense, and a "pop" sound was heard. I shut down the coil quickly because racing sparks tends to burn up the secondary wire on this coil.

Paul, all,
Yes, interesting results. Here's the dimensions and inductances for the primary.
TT-42 primary:
I.D. = 6 1/4"
tap (turns) diameter (inches) uH
14.5 11 3/16 58.2
15.5 11 1/2 66.0
16.5 11 7/8 75.1
17.5 12 3/16 84.7
18.5 12 1/2 95.1
Note, this primary is difficult to tap because of the insulated wire,
so I only tapped at 1 turn intervals. I didn't try partial-turn tap points for
these or previous tests
I also did another test. I tapped the primary at 14.5 turns with the
6" x 24" toroid, and I got racing sparks about 1" from the top of the
winding, and also at about 1" or 2" from the bottom. These were
intense, and a "pop" sound was heard. I shut down the coil quickly
because racing sparks tends to burn up the secondary wire on this coil.
