   I can't see any reason why a good RSG couldn't be made using a 
metal disk to hold the electrodes; it would be fitted with an 
insulating hub which wouldn't have very much stress in it 
(particularly if the disk were made of steel) and there should be 
some significant heat sinking to the disk.  There were certainly gaps 
made that day in "the good old days of wireless" and they would 
certainly get around the problems of expensive materials.  Any thoughts?
