Thanks for the great input!!  I'll see about something on this order for 
a future Educational Video.  The next one is going to be on the long 
awaited spark gap systems.

I now have all my caps mounted 10 feet in the air ( on a wall) with the 
driver system for maggey #11-E.  I have no real barrier for them however. 
 I don't think they are a problem as they are in soft polypropylene, thin 
walled cases with vent plugs.  The more important issue is rotary gaps!!

  Man... I have seen folks run some of the shabbiest gaps in the world 
with electrodes barely hangin' on!  The main consideration is where those 
points will go when one releases.  The imbalance posed by an electrode 
loss is sure to destroy the gap wheel milliseconds after the first point 
flys off.  I have done this. I know what happens!!

This is the number one issue after electrical safety in coiling!  
Everyone wants a rotary and gets one as some sort of "right of passage", 
often, far too early in their coiling career!  I was lucky and planned 
for the event with a shield which, ultimately, worked.

I once saw a wheel with glued on electrodes which spun in the horizonal 
plane and at "GONAD level"!  I declined the opportunity to see it work.  
The key is knowing the plane of failure and, if unshielded, put it in an 
area where the electrodes will do little damage which can't be repaired.

Maybe more on my tape...
