Ok I have the solution. On a saw with the typical pointer indicating
tension you mount a mercury switch. 3 wire mercury switch. When the
pointer moves one direction as the blade warms up the switch tilts
and a tension motor begins to increase tension until the mercury
switch is again in a neutral position. As the blade cools and the
pointer moves in the opposite direction the switch indicates to
loosen tension. You zero the mercury switch when you initially adjust the
blade
tension.
What could be more simple? :~)

More simple? Easy... How about - a scantily clad brunette leaned over and
poised for adjustments as needed. Requires no engineering effort, pleasant
to work with, guaranteed to keep you focused, and... can clean up
afterwards.

***Note*** Some have tried to substitute blondes for brunettes with dismal
results. The retraining time between cuts was prohibitive.



Well that was cute in a Jr.High sort of way but does not solve the
problem of having to stop the saw, open it up, and check the tension
every couple of minutes.
