Finishing the Secondary Coil

Just finished coat of varnish number six. That's it, feels pretty smooth now so I am going to say it's done. After allowing to dry properly (about an hour) I removed the coil from the winding jig.

I removed the bottom end plate from the secondary coil which allowed me to mark up the perspex disc which would support both the secondary and primary coil. This was easily achieved by simply using the end plate as a stencil.

The above pic shows the hole positions marked, behind is the secondary coil base plate with the mounting bolts in place.

The mounting bolts are 7 X 6mm nylon and one steel 6mm bolt. The steel bolt has a copper lug fitted under the head. This steel bolt will be connected to the bottom winding of the secondary coil and will complete the connection to ground through the perspex mounting disc. I think this is a really neat idea and will mean the secondary coil can be easily removed.

Will drill the holes in the mounting disc tomorrow and post a few pics of the secondary coil in situ.
