Welding rods in a linear static gap will get quite hot; much hotter than
copper pipes. It should be tried only with a hefty blower, otherwise spark
quenching detoriates: after a few seconds the HF output will drop.
Construction of the spark cage will also be more difficult.

I am designing a static spark gap using 1/8" tungsten welding rods (yes,
thoriated but to be used outside). I have access to phenolic fiberglass
to support them. I have a total of 10 rods that I would like to lay
parallel and still have some way to adjust gap length. Of course I would
love to build a SRSG but that's too involved for now. Any suggestions?

but do you need that extra diameter? I am using 1/8" dia pure welding
tungsten no thorium ( and you know what power Im dealing with ;) ...
and have very little wear and erosion problems.. plus the minimal
diameter makes it easier on disc design and dwell time...
