that's nice. I cobbled something together on my roaster, but I've never been very happy with it. Keep us posted on how well it works.

Fantastic job!
May I just ask as i'm contemplating with my own collector, however im lost with what kind of fan i could use with high temperature. i could get my hands on blower fan mostly found on cars but those are made of plastic. my cyclone would be based same as on this post

You should stay away from plastic fans in my opinion.
For my own chaff collector I purchased a DC blower from Aliexpress:

It works great for my Kaldi Fortis roaster with great flow control with a DC PWM controller.

As DanoM posted, you want the metal version because of the heat. I've been using the DC blower purchased from eBay and it's been good especially because of the speed variability of DC motor via PWM controller.
As for my metal cyclone, it's been working without a problem but due to the small pipe diameter, it doesn't produce as much suction as I want. Because of it, I'm in a process of building another one with this larger cone I already purchased, 2" diameter inlet pipe and 2.75" diameter center pipe. The construction method will be the same and I expect this one to be little easier since that cone is thinner gauge metal.

Test run finished.
Size comparison with the previous version.
Final setup.
It works better (higher suction) than 2.0 version. I didn't have to make this one but when I tried to make this cone the bean hopper at the top, its face was disfigured during the process of removing the handles. It would have looked bad as the "crown" on the roaster so it became the new chaff collector.

Looks good. Reminds me of a Super Jolly grinder in stainless.
I've really enjoyed my cyclone chaff collector. Even with small roasters they really work well; especially with variable air flow controls.
