I have been trying Scott Rao Hario V60 pourover this week. 1:17 and blooming with 2 parts water the first 45 seconds then splitting the rest into 2 pours. A little stirring is included. We like it.

My brew ratio is 1:17 (exactly 59.5 g/L). That's roughly 8.5g per 5-oz cup.

I'm looking to hire someone to teach/help me to find the best roast profile for the 3 types of coffee that grow on my farm in nicaragua. I live in LA, but but could go anywhere in so cal with my Behmor for a roasting lesson. Please contact me if you're in

When your wife thinks 30 grams for a 6 cup setting is strong, you learn to drink muddy water when you are making coffee for both of you.

I use a rule of thumb of 60 grams per liter. 8 cups (1 liter, 32 oz) = 60 grams, 6 cups (3/4 liter, 24 oz) = 45 grams. 10 cups = 75 grams 12 cups = 90 grams

Not so much a 500g 'bake-a-round' anymore!
Thanks for chickpea advice. It will no doubt come in handy!

I had some success today; finding an oven proof bowl at Kmart ($6) and was able to drill it! I only bought one though because I was sure it would break.
It also has a nice indent on the lip so if I make a stainless steel ring they should just slot together and its own weight should hold it down. The pics are a bit distorted due to wide angle lens.
Consolidation or laziness. Either way it works for me!
I hereby name him;
"i2q4t & coffee".
I finally found a good size chamber for the three elements at 'the Salvos' charity store. A nice stainless steel ice bucket $4. The bowl is from a super market. Total roast chamber size is 6.3l.
In the Australian electronics magazine 'Silicon Chip' there's a design for a motor speed controller that is supposedly much better than a standard SCR or Triac-based controller. The article says, most triac based controllers can only use the second half wave of the 230VAC mains which is a max of 160VAC to the motor. This is a full wave universal motor speed controller that uses a PIC12F675 mirocontroller for precise phase control and also uses current feedback and a soft start.

I'm just wondering if this would be any good for motor speed control or does the zero cross, TCP4, 10k potentiometer and crydom D2425-10 do the same thing. I'm guessing the unit would cost about $60 to build.
I'm sure it would work. But the TC4 or similar system will give you much more than just blower control. Automated heater control and data logging.

My old roaster uses a diy triac dimmer based on the circuit in the link below. It has worked perfectly fine controlling a small universal motor. My broth er still uses it regularly controlling a 900W vacuum blower.
OK, I'll stick with the TC4 then. I'm just unfamiliar with the system, (manual overrides etc) and can picture a volcano spewing out flaming beans!
The article did mention the dimmer circuit.
I purchased a 750 watt vacuum motor thinking I could probably do with a bit more power than a 600 watt. I wasn't expecting such a size difference though....this thing is huge! I think it's probably too large to mount in the water filter housing.
If I was to try reflowing some hot air; what temperature do you think these vacuum motors could handle?

How's the build coming along? I've got my roaster set up with one of the makita hand held blowers with a 2000W (at least thats what ebay told me) heating element since I may have blew up my previous heat gun element atm. For some reason I'm only about to get 200-250g green beans roasted without having to lower the blower too much to a point where the beans dont circulate as well, i'm thinking its probably my cocktail shaker head not having large enough holes so i might have to change that arrangement.

I'm thinking about getting one of those BigW blowers too and hopefully that helps with circulation a bit more.
