Re: [TCML] Coil pics & many thanks

[bartb <bartb@xxxxxxxxxxxxxxxx>]

Hi Andrew,

The 15/60 explains the power (thanks). The coil "is" working well (in 
the garage). Outdoors, there are less objects to affect the tuning, so 
it's common to tune inward on the primary a little when running 
outdoors. This biggest problem is we have to wait until we see the 
sparks clear enough to identify length. By that time it's dark and we 
tend to get in a rush and don't quite tune as we should. That's par for 
the course running TC's outdoors. It really helps to tune the coil 
outdoors the night before you intend to run it. Thus, it's ready to go 
for photo's, friends, or whatever.

Take care,
Bart

It's a lot of construction pics (including variac brush repair) & a couple of videos of the finished coil. I put the album together mostly for people who don't know a thing about coils so some of the captions probably explain a lot of stuff you already know. I tried to document all the construction steps but I can't seem to hang on to my camera :(> > > > http://picasaweb.google.com/andrew.nettles/My6InchTeslaCoil?authkey=q3ac0VTAgSY> > > > Thanks to many people who gave me advice through the list, have excellent websites, & answer emails. I don't want to neglect to mention anyone but especially Gary Lau, Ritchie Burnett, Terry Fritz (among many things I blatantly ripped off his cap design), John Freau, Bart (JavaTC Rulez), Alan Majernick for the Oriental reaction motor & super cool rotor, and Bill Noble for helping out with the variac.> > > > Feedback of any kind would be great.> > > > Hopefully I will be able to permanently set it up somewhere soon - right now it's in someone else's shop & it's kinda hard for me to get time to play with it.
