New 4 " system: SOTA on sec winding direction
Original poster: "Dave Hartwick by way of Terry Fritz <twftesla-at-qwest-dot-net>" <ddhartwick-at-earthlink-dot-net>
I searched the archives(!) and the consensus seems to be that winding
direction does not matter.
I wind my secondaries from left to right since this seems to naturally fit
I notice from multiple pix on the coiling sites that most guys wind from
right to left.
It is inconceivable that this makes any difference, but I'm wondering what
the latest thinking is on this??
The new secondary is typical: 4.25" PVC, wound for 24" with #26 Nysol magnet
wire. One of my goals for this coil is to achieve an operating freq that is
as low as possible. I want to be able to utilize 2 -- 0.05 mfd Condenser
Products caps in series (unidrive) for a total of 0.025 mfd. For this
reason, I think I need to wind as much inductance into this small secondary
as possible. This also accounts for the rather longish 6:1 aspect ratio.
I'll be using 5 kVA Pig or MOT power, Slinky toroids, mildly conical(?) 1/4
copper tube primary. Ballasting is up in the air. I need to study this.
Apparently, MOTs are not the best device for ballasting.
I have an excellent air blast gap, but may utilize a 10,000 rpm AC motor for
a screaming ASRG.
