Topic: Variable FR Roasting - update (18 lines)
1) From: Ben Treichel
I found out that if you supply a cold FR+ with ~ 102 volts ac (measured 
at an unloaded variac) that you will be at 350 in about 4:40 & have a 
13:40 roast to the start of 2nd. FYI- that is with 84 grams of green 
(not peabeary its faster), a 12 volt wall wart that measured about 12 
unloaded, ~ 70f ambient.
Or to shorten the story. If you want to slow down your FR to a 12 to 14 
minute roast, step down the wall voltage (either a fixed trans or 
variac) to around 100, dc power the fan, and use 3oz's. You will get a 
reasonable profile.
