Hi Guys and thanks for the compliments. Yea, i can't wait to see it make that first drop either

Actually I have thought about how to get some airflow and positive pressure in the bays, but I think I'll wait until I do some testing first. I'm going to dry fit it all together one of these days when the weather cooperates a little bit and load the bays up while I've got it secured to the stand with the motor running and see what it does when I pop the bay doors open. I'm hoping the air rushing over the opening creates a negative pressure and actually pulls the powder out as well as creating a disturbed airflow that kind of boils the powder while it's in the bay. If all of this doesn't work I've got a plan for a simple airduct that I could include for scale purposes that would allow me to run a small tube to both bays giving it the positive pressure I might need. When I do the test I'll take a picture, and if it's worth posting I'll put it on here.
