[TowerTalk] Grounding/Bonding Lessons Learned

Good ol' dirt and particularly clay works as good as the high priced 
spread.  We've even used dry sand successfully.

The igniter charge is a fine powder packed into the cap.  A bump, drop, 
etc will knock it loose.  One of the reasons I purchased a carton at a 
time is they were pretty well protected, but still require careful handling.

I've only had two out of several cartons that were a problem. Alternate 
methods of ignition worked well.  I'd think goof old 4350 would work as 
an igniter and is safe to handle, but have never tried powder.

Eyes and hands are vulnerable when using alternate methods of ignition, 
so be careful
