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

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 ****es 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.
