After faffing around for a few months and then getting all the parts together may I present to y’all:
“Pigeonman’s OVER-BUILT Cyclone Seed Separator”
A motto that always gets me either top of the class OR very fucked:
So I took the original method I use to separate seeds using a vacuum and stepped up my game by building a cyclone dust separator which will catch all the spoils for hash/dry-sift leaving the seeds in the original bowl, and nothing makes it to the vacuum cleaner’s drum!
First off, what I do is this:
But then I built this:
And while the system “should” catch everything I wanted to minimize the suction so I used an extra fan controller i had kicking around to drop the 6amp shop vac from “full tilt on” to “barely running”.
I over dry the flowers, and then wearing gloves I hand crush them to separate the seeds from the “chaff” making it all look like this when I start:
But then when done:
This in addition to an added choke hole to the bottle means I can “pulse” control the level of suction making the cyclone magic happen.
Here’s a video showing the system in action from a pile of crushed dust to nearly clean seeds.
(warning, there’s a high-pitched tone due to the cyclone system, volume DOWN.)
Finally here’s what ends up in the cyclone bucket:
You can see it’s easy to brush into a container to end up dry-sifting later. 
And the beans!
