How is the screw fitted on the secondary? Is it fixed in baffles?
The coil has been varnished with 10 layers of varnish - are sodium salts
still an issue? Will use gloves anyway.

I use a small 1 x 1 inch x 0.5 inch thick piece of solid brass under the
base. It is drilled and tapped and the sec coil screws rapidly into
base with a
standard 3/8-16 NC thread. A second hole is drilled and tapped near the
edge of this brass piece such that a permanent ground wire can be hooked
to the base (internally) and then the coil is quickly screwed into place
it receives it's house external ground thru this brass piece.
Makes for very fast setup / teardown of your coil for transport.
Also, best to handle the sec coil with nylon gloves so you don't get
highly conductive hand sodium salts all over the sec coil.
