Shop Notes 10/25 - Tesla Coil secondary rebuild

Most recent experiments were working with this Tesla Coil, trying to  tune everything properly into high-quality resonance.  Unfortunately the math used to wind the secondary had some bad assumptions so it would not get to the high level of magnification I was looking for.

Cutting the disks and slats for the next coil form

It was tricky trying to find a setup to cut the 3/16" slots in the disk, but I ended up using the mill for it.
In retrospect I should have just made a jig and done it by hand with a wood saw.

Finished cutting the batch of wire guides to fit in the slots

Cutting away the excess material on the coil forms that will decrease efficiency in the resulting coil

assembled (just some light taps w/ a hammer to make sure everything's seated)

And wound.   Using 1/8" thick hollow copper tubing instead of the thin 20awg wire that was used last time, that should hopefully fix my issues.

The thicker wire makes the spacing much closer together which increases the distributed capacitance of the coil.

If I sized everything properly, this should allow the coil to function in quadrapolar resonance, which is the true proper goal of a Tesla Coil secondary.

If I have time I'll try to start testing/tuning it tomorrow.

Hope you enjoyed🤠
