hi all
if you want a good gaurd for this spark gap design i suggest
extruded polycarbonate (macrolon) excuse spelling this stuff can be bullet
proof so should be ok
i would say the main dangers are indeed the rotor coming loose but no more
so than other risks associated with coiling
anyone with any regard for safety would never opperate a rotary gap without
a full enclosure anyway. which i come into the class of when im at home
although when i go to teslathons i enclose my gaps with a scatter shield
yes this design needs consideration but the original builder suggests a
gaurd
cheers
colin
