Stan shows the chokes two different ways with his VIC transformer. One method uses a few solenoid coil type layers, with quite a few turns. The other is a series of tall narrow coil forms, each having only several turns in each layer. The goal of the winding style is to output a separate pulse for each layer or coil form. In order to do this with a solenoid layer choke it needs to be build as a pulse forming network. The capacitive reactances between the layers must be kept separate. (This inter layer capacitance is in series with a layer's inductance.) This separation is accomplished by introducing an extra inductance between the ends of the consecutive layers. And this is tied up in the winding technique.
After the first layer is laid down, you want to start the next layer at the same end as the first layer. Otherwise, the outputs will maintain continuity, without breaking up into discrete pulses. The far end of the wire is brought straight back to the starting side - usually between two strips of dielectric. The trick is to bow the wire out at about 30 degrees, then put a sharp kink in the wire with your thumbnail, to aim it on back across. Before the next layer starts, the kinking process is repeated a short distance from the starting end.
This system adds a half turn inductance between the layers.
Stan specifies that the chokes are wound bi directionally, over and back. He also said in an interview that he sometimes provided misinformation, to preserve secrecy from his competitors. A Tesla fan showed me the uni directional winding back in '62, when that group was still close to the source.
Might be worth a try.
