[Elecraft] Toroid Winding Question

[John Young]

I've not had a problem - yet,

Has anyone tried painting the rough areas with a little clear nail polish?
Seems simpler than trying to sand or drill and should not affect the inductance.

Yesterday, while finishing one of the first toroids in kit, I noticed one of the turns had crossed over the previous one, so I began to unwind it. Then I noticed that the wire had the enamel nicked in several places and chose to replace it.

Currently, I'm "pushing" the wire through the center of the core rather than "pulling" it so as to keep it away from the core to minimize scratching it. Obviously, though, it's not possible to know if the winding has been scratching in making the bend around inside.
