My vacuum kiln is driving me nuts. after spending way too much time on it I
broke down and bought tthese heating pads
http://www1.mscdirect.com/CGI/NNPDFF?PMPAGE=4470 the silicone rubber pads
I use 4 all together the 700 watt ones and I use two controllers
http://www1.mscdirect.com/CGI/NNPDFF?PMPAGE=4470
The robotemp controllers on bottom. Well so far I have had two units fail and
just kick on the full heat. Well that is pretty hard on the wood. One has been
working fine but I sure cant trust it. it pisses me off spending 80.00 and they
are unreliable.
I just want a simple dial to choose the temp.I don't need a thermostat to keep
the temp at a certain level.
are the router speed controls what I am after? I have one on hand.

Steve,
Being you don't need actual thermostat action and adjusting the heat
level manually works, a router control should work fine. 700 watts
is is only about 6 amps and well within specs for most router
controls. Using 2 heaters on one control long term might be too much
current for some to handle.

A little more fine print: The mfg spec is 7 amps max without an
external heatsink, 12 amps with. You would still need to supply a pot
for control and wire it. IMHO, with an external heatsink, 1 heater.

If all is as appears this would handle 2 heaters.

I just was not sure they were the right thing. I have found what I do need to
get though.

they go for around 100.00 and they are extremely reliable. a bit more then I

should work as long as the heaters are well under the controller's amp
limit.
