@ Hossfly.
I think I will put the thermometer in the Quart paint can the next batch of balsa that I cook.
Just to see what it really takes to be consistent.
I have my gallon retort set up for it already.
But I don't think I will ever go to a PID set up because , I don't make that much charcoal at one time.
I usually choose to cook the charcoal off with scrap wood from trimming my trees rather than using propane.
Not because of the cost.
But more to get my yard cleaned up.
And , going back to basic methods gives you an out if gas or electric prices go thru the roof even more.
