Topic: Newbie FR Variac Profiling, Part 2 (2 msgs / 50 lines)
1) From:
Ok, Jim Schulman et al, here's my second attempt at variac profiling with my
FreshRoast Original;  much better results, I'll try a cup this evening and
several times over the next few days.  Reducing the weight seems to be
important, I'm betting 60g would work even better (FR not tilted, no
"chimney" extension, that'll come in a bit).  All other values are
approximate ... and remember, I'm using the Pelouz inserted to about 1" from
the bottom, and slightly off-center; my temps seem to be closer to the bean
temp than Jim's, so don't know what the air temp is coming out of the
blower.
Bean:  Ethiopian Ghimbi Natural Decaf
Weight:  65g
Roast Time:  @6 minutes
Time      Voltage  Temp      Notes
--------- -------- --------- -------------------------------------------
45 sec    125v     ???       Temp seems to reach 300 during this stage.
3 min     95v      340 - 380 Slow ramp up this time, a few early poppers.
30 sec    125v     410       Push roast to first crack.
45 sec    110v     420-ish   Through first crack.
1 min     125v     ???       To second crack; stopped immediately, don't
like
                             this bean too far into Full City.
Roast looks great, already starting to smell great.  Will be experimenting
with Sumatran Mandheling Natural Decaf '01-'02 later today as well, to test
a decaf MJ blend for my friends (and dinner guests).  Then back to my
staples, Sulawesi/Yemeni (but probably tomorrow, I'm stuck at home today
meeting an unreasonable job deadline -- grrr).

Tod, Hope it tastes great!
You're right about the temp readings, they seem like partly bean/partly air
