Yes on all.
 I'll send both. Up to you how many you want to use. Don't worry
 about the thermal couple wire as I can always buy more. I will have
50'.
 anybody have any experience welding junctions on K type thermal
couple
 wire?

The way we used to do it is probably not environmentally acceptable
anymore.
Twist the wires together, then hook both wires to one side of a electric
cord, put the other side of the cord in a pool of mercury under a layer
of
oil, and dip the couple junction down to the mercury. The arc welds a
nice
little ball on the end. Usually used a variac to cut the voltage down,
but a
12 volt car battery would probably work.

That sounds great Bill! LOL Where do I buy the mercury?
Can I just heat it with my tig welder?

Is there a reason you would not use the 2 dollar varistors from Radio Shack?
Just solder some wires on and you are ready to go. Would it be a problem
taking resistance readings with your setup? I played around with them some
on my rads, they seem to be quite accurate.

Since I had to put out the money anyway I wanted something that could
handle exhaust temps. varistors I don't think would handle 1800 F.
