Broken wire?
If the wire breaks, simply peel o more wire from
the top of the coil. Use a razor blade to separate
out the top turn of wire.

Place a small amount of
glue between each layer
to hold the end cap
assembly together.
Place a small amount of glue
on the rim to keep the cap
in place.
STEP 12: Assemble the End Cap
A. Build the end cap for the secondary according to the diagram. Don’t worry
if it’s not pretty—remember that with the toroid mounted, you don’t see the
end cap! DO NOT glue down the bolt in the cap. The bolt should be a little
loose because when you mount the toroid, the bolt will be pulled up against the
ring terminal, creating a secure connection.
Which glue do I use?
Hot glue is great because it’s sturdy enough to hold
the coil together, but if you make an error you can
still force apart the pieces. If you prefer your coil
more drop-proof, use super glue or epoxy. Note
that super glue clouds acrylic, so use it sparingly!
B. Glue the end cap in place on top of the secondary tube. Rotate your tube so
that the secondary wire is taut and does not sag into the tube! Sagging wire
acts like a breakout point inside the secondary and will cause internal arcing. If
you want to be extra safe, you can insulate your exposed bit of wire with some
hot glue.
C. Check for continuity between the bolt and the bottom ring terminal to verify that
the wire is still intact.
D. Thoroughly remove any stray strings of hot glue inside the tube. Any stray bits
inside the tube can result in internal arcing when you power up your coil
later.
