I place the thermostat probe in an egg box along with a thermometer probe. I also have a thermometer probe hanging free in the incubator so I can monitor temps in and out of the egg box. PS. I LOVE our Herpstat too, very little fluctuation unless I open the door.

Sorry, I don't have experience moving a clutch. Maybe some one can chime in with the best way to go about it.

How far are you moving?
