Steam Punk Temperature Gauge

[electrosteam]

My first post.

I have acquired a 150 mm diameter steam pressure gauge scaled 300 psi intended to be used as a temperature indicator for a pizza oven.

Current thinking:
K-type thermocouple in oven,
1.8 degrees stepper motor directly driving the pointer,
Arduino assembly for control,
Buttons; "Set Zero", "Set Fullscale", Increase, Decrease,
potentiometer; ambient temperature.

Suggestions welcomed.
