why to cover the moter?maybe will heat more if it covered


Because you aren´t always aware of what your motor does, eh? There is ALWAYS the risk of
sparks or parts of the motor running hot.

Just seperate your two parts, motor and milling cabinet. Always use the safest possible way.

Sorry, this is in NO way meant arrogant but I would never have asked the why-seperate-the-both-question!
It is YOUR safety there. You´re not playing with 10g of lightly con tained black powder. That jar looks
like you´re gonna make a lot more at once.

So, take that tip and add at least one layer of thick wood between motor and jar, so no powder can directly fall onto/into
the motor.
Mo overheating issues then! I´m using the same design on my mill.
