Re: [TCML] DIY dent-proof Toroids

[jhowson4@xxxxxxxxxxx]

Brilliant, With this method it would be really easy to experiment with different shapes. 
I have always wanted to make a toroid that the bottom surface contoured down and became the same diameter as the secondary. (think like one of those mostly spherical water towers) 
Because the top of the secondary is the same potential as the toroid, it would become like one continuous surface. 
Might be cool to try. =) 



Thanks,

Subject: [TCML] DIY dent-proof Toroids 

Those who had enough of dent-sensitive toroids made from aluminium ducting, 
might appreciate this diy alternative. I've succesfully used this method to 
create 
2 robust toroids (26"and 32") from scratch, each on a 35 Euro / 45 USD 
budget. 

Phil Tuck has been so kind to publish this method on his website, thanks 
for doing so Phil:

When I was making this toroid I decided to perform an experiment 
with an uncovered centre plate and a non-conductive gap in the 
circumference. 
The hypothesis was, that this could prevent losses caused by Eddy currents 
in the shorted loop a normal toroid would be. 

How this gapped toroid behaves can be viewed here:

I conclude that a non-conductive gap in a toroid's circumference should NOT 
be used. 
It creates sharp 'edges' on the toroid, which behave the same as break out 
points. 
This influences performance negatively in a larger order of magnitude than 
the gain, 
as described in the hypotheses, would be. 

Feel free to agree or to disagree.
