I am thinking that the torroid of your reference is that torroid what acts
as an discharge preclusive electrode as located at the top of the high
frequency  alternator circuit, and that the torroid is usually  constructed
out of alluminum when constructed by means of an use of a lathe what is used
to spin the two parts of the torroid what are then after fitted togethr so
to form the torroid.

When you say "ducting" I assume that you are alluding about a type of a
metallic sheeting material what you purchased from Shopco........... and
that you spent your time moulidng this material into the two halves had of
the torroid?  I am of the opinion that there are sources of the supply where
it is that such a torroid can be purchased, but I will have to spend sime
time to locate the sources of some such torroids already manufactured what
one can make of an use at the top of your most resent coil.  I will research
and find the source where one can secure of the purchse of them, but I wil
have to defer on the referring to you of this source until some such time
that I can get to the finding of the sources of some such related torroids.

I am not sure what you are rfering to when you allude of an sue of the
"ducting", but the usual way of the securation of the torroid used at the
top of a Tesla Transformer is that one of the manufacture of the tooroid
available form a manufacturing source; moreover that the maufactured torroid
is made from aluminum what is formed into a torroid having of its two parts
formed and put to gether, and that the two parts fo the torroid are formed
of the spinning of alluminum, of its two parts, what are spun on a lathe, of
its two parts, then after fitted together.

And the switches what you allude and inquire about: I assume you are talkng
about switches (relays) what are in an oil baths, and you indicated that the
switch operates at fifty amperes, of its contactor capabilities, when the
coil had of the same relaty operates at two hudnred and fifty volts, and you
need t, further inform me as t the details of this type of an "switch"
before I can find out, for you, as to the availability and cost?  The same
is true of this...the switches are available from sources and with the
additional information what you need to supply, then I will find out, for
you, about of availabiliyt and cost, but I will have to have some time
allowed of yourself toward me so to be allowed to, sucessfully, find out for
you as to availability and cost but before I can do this you need to supply
me with the specific information as to the operatng voltage and current had
fo the coil of the switch and the contactors had of the switch either in an
oil bath or in the open air as located on a relay panel?

After you supply, to me, the needed information allowing me to locate of the
source and cost of the items, fo your request, then I will be able to get
back to you as soon as I find out the information what you are needful to
know abut asd to have.

Write soon...
