My first thought was : What is Bill doing making such a small coil?
Is it a toy one for Xmas. Perhaps the Griffith Observatory (which
you are doing if I recall) needs one for a small room like a toilet
or broom cupboard?
Resistors for MMC have been debated many times. Some people don't
use any. Most use a single 1/2 watt 10M resistor per cap. This has
always worried me as it is way overvolting the resistors rating of
perhaps 500 - 800 V but in this pulse application they don't seem to
fail. Terry uses 4.7M x 2 per cap. I use 3.3M x 3 per cap. I
don't think it has been proven who is right. My guess is it depends
on the application. For home use they are probably not required for
a small coil. For a reliable larger museum coil you need to minimise
failure modes, so use 3 or more.
