Re-gapping 3 ground electrode sparkplugs

[Al Streicher]

Actually I think wire gauges is best for sparkplug gapping. The problem with 
most of the usual bending tools is that they sit too close or touch the 
ceramic surrounding the center electrode.  This is the tool I saw on an 
aircraft tools site, 
http://www.aircraftspruce.com/catalog/topages/precisegap.php. I imagine 
someone with the right shop equipment could make one.

thanks,
Al
