Re: [TCML] 10" coil specs; Thanks Jeff Miller



Hey James, 

Mind discussing your capacitor? Just general specifications. I have been cataloging various capacitors types/designs for various coils in order to gain a better understanding of what different caps can handle for short or long duration's . 



Thanks, 
John "Jay" Howson IV

Hi all, 

Coiling does take alot of work but it is a work of love, is it not? Thanks for the comment Jeff. 

Here are the specs for the 10 incher

Note this is with the bigger top I am currently building so no pics of it running with that size top. 

All that is left to build for it is a control panel and cart for the piggy. 

I think this hobby is great. Challenges the mind and ability. Now I just have to get more people near me interested and building coils. I have never seen other coils in person but hope to attend a coilathon in the future. 
This list is what makes coils that run well possible for the average guy. I learned more about electricity and components from this list than was taught in school. People here on list sharing info and technique is why I have a 
10 foot arc throwing machine and for that I applaud . There are so many great ones on this list I would like to thank for posts in the archives that helped me to understand just how these coils function. So I won't name names, you guys already know how much info has gone into this list and who posted it. Thanks for all of it.
