What type of coil are you building? Unless you are using feedback (like in a sstc/vttc) the direction does not matter.

The forum has a search function for a reason.

It doesn't matter, as long as all of the winding is going in the same direction, including your tuning wire.

Whoops, I guess I left that tab open too long.

A TC will work with the secondary wound in the same OR opposite direction to the primary.

I haven't proved it yet but I'm of the opinion that
arcs are less likely to strike the primary or strike rail
if primary and secondary are wound in the same direction.
If this is true it's a small effect and something that you should NOT worry about.

All my primaries are helical which when turned upside-down there is no change,
I need to wind a flat primary that will reverse winding directiopn when inverted.
One more thing on a very long list ;)

The dents and the crimped end will not affect operation noticeably.
