I just finished mine also, took me five hours because my dremel is a ****ing toy. I had the most trouble getting the thermometer to hold to the clock pod, I stays in place with the help of flexible plastic and much super glue. Also getting the thermo couple through the firewall was a major bitch. The funniest thing is that it's getting dark and snowing pretty hard and there I am an idiot lying on ground trying to get the thermo couple through. Jackie thanks for the great idea.
