Good luck Kyle and welcome to the world of forge heat treating. LOL
I wished you had access to an oven with controls so you could see each temp's colors. It is how I learned through my job. I HT'd O1 quite often and recognize the color and glow for 1475. Daylight or fluorescent light you get a practiced eye for where you want to be. Keep working and be patient and you will get there. I am trying to think of how my brother put a cheap thermocouple in his forge and hooked it up to a voltmeter and he had a chart that compared the millivolts to the actual temperature. It was inexpensive. Maybe somebody here knows.
