Finished coil with header epoxyed on each side to give it strength.

Each joint was inspected with a jewelers loop to make sure it did not short out
with the joint next to it. 

I then applied a thin coat of styrene mixture between the joints only to further isolate the joints. 

This styrene mixture was picked because it will not lower coil Q as much as most things. Anything will lower the Q of a coil, some more than others. The mixture is made with Acetone (or MEK) and styrene peanuts. The styrene peanuts are the kind you pack things in to mail items, you know, the ones that go everywhere when you open up a package!! LOL   Only use enough on the coil to do the job and be very careful. This mixture is very flammable and not good if inhaled. Use plenty of ventilation.
