Posted Tue Jan 29, 2013, 4:11pm Subject: GG/UFO Chaff venting question: What size hole or slot?
Ok, so you might think I'm a little crazy here.... I just finished building the Breadmachine drive, and now I have a UFO question. A guy needs a backup roaster, right? Plus, I'm not happy with how fast the bread machine stirs, and slowing it down is going to require swapping motors to something I can dial voltage back on (i.e. DC).
So I am going to try the UFO combo. I have a springform that I will be using to space the GG up, and want to integrate a removable chaff collector using a small drink mixer/shaker. With the UFO, I'm not worried about beans being "launched" through the chaff vent, so I'm wondering what size hole to drill in the springform? I can go up to 3/4" round, or 1/2 X 1" slot. A hole is a lot easier to machine than a slot for me.
By the way, the cocktail shaker cap is SS, and it will be perfect as a food-safe wing-nut cover.

So I roasted 14 oz of Huehue last night in the UFO base. What I liked was how quiet it was compared to the bread machine combo. Unfortunately, I think I need to dial back my temps. Due to the much slower stir speeds, the roast was uneven compared to my previous roast with the bread machine combo. My Aeropress brew tonight from that roast had distinct "char" elements in the mouthfeel, even though visually it looks identical to the roast from the breadmachine base and I pulled both roasts as soon as I hit second crack. I did have to cull some beans that looked burnt and one that looked like it found a cool place to hide.
