Maybe I will do it next time, or find a momentary handle with some

A joystick.

Wow, this is great, I see how I could have used it!!!!

That one is cheap and the pot is clear in the photo. A panel-mount one
would be easier to add to throttle a variable regulator in the control
box you built.

The resistor between OUT and ADJ sets the constant current value. For
a 1K pot, 4mA through it will give you an output range of 1.25V to
5.25V.
