I have no problem making a tempering bath and keep the bath at correct temperature. My problem is how to keep the chemical once pour into the drum not to change. The Jobo had the drum submerged but how do I submerge my drum in my tempering bath?
I could make a higher precision tempering bath than the Jobo but I don't know how to keep my drum underwater to keep the chemical from dropping the temperature. The Jobo has the coupling and drive system which I found difficult to duplicate.
