I actually looked at that model and considered having a piece of aluminum stock I had milled and machined to do it. I have a close friend who has a machine shop. But figured it was too much trouble. The push button switches I had to buy in bulk, and I ran across this PWM switch and went that route. I really like how you linked the scale to the CPU screen for easy viewing. My Lyman M5 is sometimes a pain because I have to lean back in my chair to see the setpoint. What kind of setup is that?
