A time lapse I threw together of my self building one, as well as Johnny and I taping a few more 3" ball shells. I cut a lot of the pasting as it is a looong process and my target was originally under 10 mins! We did not get the lift expected from my powder, and had some lower than desired breaks. Could have to do with the fact it was granulated only 24-48 hours before firing, very likely still moist.
