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

Transparent Fluid Bed Design

When reconfiguring the build a defect was found on the heater lid part. It still functions well to hold the RC... a high temperature PLA reprint may be made for a fix.

That's a very nice rig you made. I had no idea about the high temp PLA and the gizmo to hear 1st crack better is a new idea to me. So much nicer than holding my ear next to the roast chamber.

One Idea i might contribute to your build is to roll your own heating elements. The ones that come with poppers are made with the cheapest possible material, and just don't last too long. Ive been using nichrome 80 in 20 gauge, and an element lasts over a year. Use a knitting needle to roll it. Just get one in the mm diameter of your old coil.

Thanks for the tips on rolling custom coils and wire choice. That may come in handy in the future if there is need to do repairs.

The original coils are still going strong with more than 2 years roasting and testing on them... perhaps because I don't run them maxed out. (They only run at about 50-60% of their potential.)

I've simplified the FC sound feature by removing the copper piping, and putting foil directly over the 1" top opening. It's clamped in place with a band clamp over a silicone gasket, keeping the foil relatively flat and stretched tight. The function works just as well as the complicated copper pipe design.

Hey there, I've been having a peruse through this thread cause this is a really neat design. Have I missed a part list or have you not released one? Just curious as I'm thinking of making a roaster myself and I am curious about how much this kind of setup would cost :)
One thing I'm interested in is how it's all powered, do you have a big psu of some sort or is everything just individually plugged into an extension bar or something?
Cheers either way as it's been cool to see the idea and progression
CK
You can refer to posts 21, 23, 42, and 44 for the information. Each 120v power inlet is pulled from a different circuit in the home.

Oh awesome I feel a bit silly. So you power it with a bunch of plugs, makes a lot of sense haha. Cheers, totally should have seen that
