Use a Jiffy mixer, powered by a drill motor, controlled by another foot
switch to do the mixing.


Sooner or later it is time to clean the Jiffy Mixer.

Since it is S/S, a 2,800F propane flame does a great job of burning off
the hardened epoxy with out harming the S/S mixer.

Don't try this on plain carbon steel mixers.
