Currently I'm working on installing a lightning
ground plate that will also serve as a ground for the 12v electrical system
Both Nigel Caulder and Don Casey recommend not grounding to sintered bronze plates (Dynaplate).
As far as I can tell the best option seems to be buying
some copper bar stock and bolting it through the hull
. What I'm wondering is how thick copper stock should I use? I'm thinking about a 1/4" thick bar 6' x 2" This would cover both the 1sq ft requirement that nigel caulder cites and exceed the 4' of edge that don casey suggests.
Has anyone done this?
Thoughts on thickness of copper, bolt types, type of copper and source (I'm thinking McMaster Carr multi purpose copper alloy 110 (99.9%copper).
