Dear Vince Pitelka,=20
I would just add one proviso about your Mixing Drum.
Care must be taken putting the powders into it and it should be allowed =
to stand for a period of time after mixing is completed to let the dust =
settle, otherwise a cloud will draught into the air when it is opened.
I think it is a great idea.
Best regards,
Ivor Lewis
