I just received them today from Richard.   I received Pictures ES1 through
ES8 and ES10.  Nine total.  Pictures 2, 3, 5 and 6 are old pictures that I
sent to Richard some time ago when I still had the coil set up in the
basement.  Pictures 1, 4, 7, 8 & 10 are more recent after I pretty much
rebuilt everything so I could set it up and run outside.  There were a couple
of good pictures showing how everything is set up outside that I don't see
here.  Do you have any more scanned pictures than these?

ES2 and ES3 don't show much.  I wouldn't bother me if you did not post them.

Here is some text to post with the pictures:

ES1:  This is a partial picture of my control "board".

Lower left is two variacs which I run in series to control the speed of the
rotary gap motor.  One is set to limit the maximum rpm and the other is used
to bring the speed up slowly.  Above these are the 60 cycle supple lines
going out to the coil.  One is for the rotary gap motor, the other is for the
fan motors on the rotary and the static gap used in series.

The heavy powerstat variac is in the center bottom - used to contro the
voltage to the pole pig.  Above that is the ammeter and voltmeter to monitor
the pole pig primary.  Above that you can see the primary feed lines going to
the pole pig.

To the right, are the 60 cycle line filters and some home made toroid filters
used in series with the 60 cylce ground connection.

Upper right is the plug for the welder (used to limit pole pig primary
current) and the plug for the resistive bank (oven elements) used in parallel
with the welder primary also to control the pole pig primary current.

ES2:  This is an old picture of my early control set up.  It looks like I was
in a hurry.  Things are not very orderly.

ES3:  This is an old picture of the set up I had in the basement.  Shown are
the pole pig, a 14" toroid, a 30" toroid and two home made rolled poly

ES4:  This is how I set up the coil to run outside.  Shown out behind my
garage are the resistor bank on the left,  the pole pig, the welder and to
the right the control board.

ES5:  This picture shows a 30" toroid mounted on the top of my 6" secondary.
 It demonstrates how I use different length pieces of 3.0" dia pvc pipe to
easily change the height of the toroid.

ES6:  This is a picture showing the old set up I used to use running the coil
in the basement.  Shown are the 14 turn primary, the secondary and a 30"

ES7:  This shows the coil set up outside and ready to run.  Shown are the
primary, secondary and a 40" toroid.

ES8:  Shows the coil running outside at 8kva.  The coat hangers laying on top
of the toroid are an attempt to prevent strikes down into the primary which I
was having trouble with.

ES10:  Shows the coil running outside at 8kva.  The long strike is to a metal
rod driven into the ground 72" away.  This is the longest srtike I have
measured with this coil.

Thanks again Chip,   Ed Sonderman
