For great spark gap balls at a great price, go down to Home Depot in the
cabinet section.  Look for the "drawer pulls".

Specifically Liberty Hardware p/n P1061C-CHR-C.  It is approx. 1 1/8th inch
dia. and has a chrome finish.  Very solid and comes with a mounting mounting
bolt.  They also come in same size with brass finish.

The great part is these balls are only $2.39 each!!!   You can make a nice 3
electrode, 2 gap, sparkgap for under $10!!
