Please see that attached photos.
Look closely at the pictures and make suggestions on how to get powder on the areas that are not being covered.
I have tried low voltage, high voltage light powder, and heavy powder.
The only thing I have not done is to heat the wheel and then shot the powder. I really do not want to do that because if it does not work then I really have a mess. Right now all I have to do is blow the power off and try something else. (I have tried heating between attempts. There is nothing on the metal as I have had it in the sand blast many times thinking there was still primer on the wheel.)
