Re: [TCML] new toroid capacitance

[Bob Wroblewski <bwroblewski@xxxxxxxxx>]

Hi Rev Fuzzy,

Do a web search for QTC.xls then you can save it and use it locally.
It is a spreadsheet program from Ed Sonderman modified by Ross Overstreet. I've 
used it quite often over the years. It has a toroid capacitance estimator based 
on two dimensions of the toroid. My two cents worth. Good luck.

Subject: [TCML] new toroid capacitance

I hope someone knows this one... I've made plans for a new toroid, but the shape 
is slightly odd, compared to what we've been using.
I acquired a pair of 2"x11.75" Styrofoam rings (each with one side flat, the 
other side rounded).  My idea is to mount these in a
11.75" round section of 3/16" plywood.  Question is, what would be the resulting 
capacitance of this topload?  I'm hoping for
something in the range of 16pf to 26pf, but not holding my breath on that.

See PDF diagram: http://www.msbministries.org/new_topload.pdf

Thanks in advance for the help.
