Topic: I'm having a good week (10 msgs / 194 lines)
1) From: R Nepsund
I'm having a good week.
I got a  Gene Cafe  from Goleta,Ca yesterday for free that I found on
craigslist.   The woman who gave it to me said that it belonged to her
significant other who had died a year ago and she didn't drink coffee.
  She just wanted to see it get to somebody who would appreciate it.
Also I'm down to the last few pounds in my stash so it's time to start
looking over SM's lists and start going     I want a pound of this and
this and this.....
Actually I have mixed feelings about the GC.   I just switched from
roasting with a popper to a heat gun and bread machine about a month
ago and I'm nowhere near finished twiddling with it.   It doesn't even
have a permanent temperature probe installed, though I have stripped
most of the Teflon off of it which was not easy.   I expect that the
GC will give me better profile control than the HG/BM would.

Wow!
<Snip>
I understand your concern with the GC.  Let me take a load off your
shoulders; I'll reluctantly take it off your hands at the same price.  :-)

What Teflon did you strip off? And how?

The entire bread pan, inside and out, and the stirrer were coated with
teflon.  I tried stripping it with a harsh paint remover, but that
didn't touch it.   I ended up using a drill with a wire wheel
attachment and touched up with a dremel with a mini wire wheel.  I
didn't quite get all of it off, I couldn't reach parts of the bottom
of the pan with it.  It took a long time.
PS: Teflon gives off toxic gasses at about 700 Fahrenheit.

I'm confused... What bread pan on a Gene Cafe? My Gene Cafe does not have a
stirrer; it's a drum roaster.

Presumably the bread pan in the HG+BM he used previously, before he  
switched to the GC.

The blue vinyl sleeve over the end of the chromel-alumel wires/ junction.
Maybe it is supposed to protect the sensing junction from the heat you
actually want to measure-?? ! ! That's sick.
If it were actually a teflon composition, 500 F probably would not melt =
it.

"I expect that the GC will give me better profile control than the HG/BM
would."
You are right- What you expect to find, you probably will find. Follow the
instruction manual directions, [hope you got one...] and the additional
hints will all make sense and be useful.
The HG/ BM has been a 5-year study for me. I rarely stick a thermocouple
probe in the pan to measure temperatures while I wave a heat gun around.
Multi tasking is not all it's cracked up to be, since I'm already reading a
timer, looking at smoke and the bean surface and listening for 2nd Crack to
start.
A quick cool- down at the first snap of 2nd means the roast is stopped when
99.9% of the beans have not even entered 2nd Crack.
Extending the time after completion of 1st before the first snap of 2nd
essentially means the entire roast was stopped before 2nd. You can
extrapolate that all you want without any temperature measurement and still
call it your roasting profile.
The march of time for an 18.75 m roast (18:45) is inexorable. For variety,
measure the "bean mass" temperature with three different, simultaneous
measuring devices. TC, RTD, solid state, IR or whatever.
Unless the laws of physics evolve, the readings will be different, and
nobody else could hope to match your numbers in a different roaster.
Even the USRC roaster among us did not start out to match numbers except as
a guide from the manufacturer or other similarly instrumented roasters.

D'oh! Of course, Allon. Thanks. It truly was confusion...
