Re: [TCML] Still stuck at 36"

Hi Gary,
Yeah, I guess size DOES matter, at least when it comes to electrodes. I used 
the heads of two carriage bolts, but they were much too small (less than 
3/16th's of an inch) for the application. I used foil tape to close down the 
opening on the top of the pvc fitting to direct the air flow, but that still 
wasn't enough. I think the blower motor is probably undersized, too. I do 
have an old vac motor sitting around, waiting to be used, so I may give that 
a try, along with bigger electrodes. If the next ssg works better, I'll post 
a pic.

Neal.

Hi Neal,

You mentioned that the performance diminished quickly with time, and was 
restored briefly after letting it cool down.  The electrodes in a single gap 
must be massive enough and the airflow sufficient that there is minimal 
heating of the electrodes.  Mine were never detectably warm.  Just what did 
you use for electrodes, and how focused was the airflow to where the arcing 
occurs?  A sucker gap pulls the air directly through the arc, and I think 
most have found it superior to multi-segment gaps.  Do you have any photos?
