Re: [TCML] Winding a Primary



Okay so my CNC opportunity fell through. The reason I went to this option in the first place was because I haven't the slightest idea how one might wind a perfect primary coil spiral without guides. Can anyone explain this process? Or link to a good website that explains it?

My old reliable coil's streamer length was gradually diminishing from white
long sparks to shorter purple sparks and finally purple sparks for about
ten seconds then no sparks. Additionally, racing arcs were beginning to
occur.

The MMC value checked out, all connections checked out, I cleaned and
re-connected the dedicated RF ground, etc.

The old design utilized two paralleled 9/60 NST, 3" dia. sec. and a 3"x12"
toroid with a spark gap consisting of four fixed gaps in series.

I suspected the transformers so I replaced these with the only other one I
had, a 15/30 NST. I ran the new transformer, required capacitance of .008uf
along with the existing secondary, spark gap and top load through JAVATC.
Modifications were then made per the JAVA.

The first light of the modified coil only produced a weak purple spark with
a break-out point. Tuning only served to create racing arcs, with no
improvement in performance.

Now I suspect the secondary. So, I rewound and varnished the secondary.
Same dismal performance as before. Now I'm about ready to loose it, to the
point I'm explaining this all to my wife.

The only thing I didn't touch was the spark gap and gap spacing. It was set
for .030" for each of the four gaps and I made no adjustment when I
switched transformers.

Sorry for the long post, but I would really appreciate any ideas.

Thank you,

Tim Flood

Hi Tim,

Assuming you're using copper electrodes, try taking some silicon carbide
sandpaper and sanding the active area of all the gap electrodes. Over
time, a partially-conducting layer of copper oxide can develop in the
gap. This layer tends to reduce the effective gap spacing and also may
become incandescent when running the gap. The result is reduced
breakdown voltage and poorer quenching of your main gap. Both of these
effects will significantly reduce the output voltage and power of your
coil. Retune your coil at lower power levels before firing it up at full
power with the newly-cleaned gaps.

Thanks guys for the suggestions so far.

The electrodes are not copper but 3/8" dia. steel round bar with tungsten
carbide silver solder on one end so four pairs of flat round flats face
each other. These steel rounds are mounted in aluminum blocks and are
adjustable. It could be over time corrosion has developed over time between
the steel and aluminum. I will disassemble and inspect this weekend.

The caps that make up the MMC are new. They checked out OK individually and
as a unit. Is it probable that a number of these caps could break down
under load?

Thanks again and I'm open to any ideas.

Hi Tim,

How are you cooling your gap? Some of your symptoms suggest that your
gap is overheating and failing to quench.

What are the details (manufacturer and part number) of the capacitors
you're using in your MMC? Racing sparks can be caused by mistuning if
your MMC is changing value during operation. This is usually not as much
of a problem with self-healing capacitors until they approach their end
of life.

How many are in each series string and number of strings in parallel?

Are you using bleeder resistors across each cap in your strings? If so,
what is the manufacturer and part number? Bleeder resistors not made for
HV use may arc over or change value, messing up the performance of your
MMC. This can usually be seen as flashes during operation,
discoloration, or resistors even burning up. Some good, inexpensive HV
film resistors include Vishay VR37 series or YAGEO HHV-50 series.

I know it was working originally on steel electrodes ok, but consider
changing them one day anyway - steel heats up hot anyway with RF, but
working in a spark gap as well, means double trouble :-)

Well I just viewed pics and video's of this years Western Winter
Teslathon 2014 at Tesla Universe and it looks like it was another great
year at Henry's compound this March in Arizona. Unfortunately I did not
get to attend this year, but it looks like despite of the rainy weather
that hit the west in early March, WWT2014 was a great time regardless!

At Tesla Universe there is a direct link on the main page to John
Forcina's photo's.... also Chris took video's and there's a link to
those as well... I just now viewed all pics and vids and realized that
it hasn't been posted to TCML, so....

Thank you Dr. Hankenstien ( thanks Henry) and Dr. Spark ( thanks Chris).
I see that Ed. Wingate attended, the band was awesome, I even viewed
KOTC (king of tesla coils) Steve Ward rockin on bass! and you had some
singers for the band this year.. haha.. good times! I'll be there next
year guys!  Dianna says hi!

 was a great time regardless!

 At Tesla Universe there is a direct link on the main page to
 John Forcina's photo's.... also Chris took video's and
 there's a link to those as well... I just now viewed all
 pics and vids and realized that it hasn't been posted to
 TCML, so....

 Thank you Dr. Hankenstien ( thanks Henry) and Dr. Spark (
 thanks Chris). I see that Ed. Wingate attended, the band was
 awesome, I even viewed KOTC (king of tesla coils) Steve Ward
 rockin on bass! and you had some singers for the band this
 year.. haha.. good times! I'll be there next year
 guys!? Dianna says hi!

 Here's a link to John's photo's and also to the video's on
 youtube....

 Coiling Rocks!

Hi Bert,

I have never cooled this gap but will do so in the future. The capacitors
are new Cornell Dubilier 942c20p15K-F purchased from Online Components.

There are 19 caps in a single string per the MMC Design Chart for a 15/30
NST.

The bleed resistors I'm using are 10meg, 1/2 watt, but I don't know the
mfg. or part number as I get them from the electronics dept. here at work.
There have been no anomalies with the resistors during or after operation.
I will check into the resistors you sited.

Phil, thanks for the advice on the spark gap. I pulled the gap assembly
last night. The steel is rusted and the tungsten carbide faces need
cleaning.

Thanks guys,

Tim
