Jim, see my initial reply below to Ron which was posted to AMPS
yesterday. 
Even a seasoned pro can make mistakes around HV. It is a very cautious
one that lives to tell about it.

Be sure you INSULATE the high voltage end of the resistor from ground.
I mounted a bleeder resister with just the supplied metal mounting
brackets.
The high voltage end arced to
ground and blew up all kinds of things. ....

Just a quick FYI...

73 and good luck

If you use the original style self centering end clamps and thru bolt you
will have plenty of reserve voltage rating at 4KV so half that is very
safe.   Mount to a bakelite board or a ceramic stand-off. DO NOT mount
directly to the chassis as I have found that the end mounting terminal
tolerance varies quite a bit from the actual end of the resistor.
