Howdy Y'all
    Well after reading the messages on this list for a few days I was =
ready to try my hand at 
HG/BM roasting literally and figuratively. I read all I could about =
HG/DB technique and figured 
I couldn't hold the heat gun and stir the beans since I have fingers =
only on one of my hands.
Then I read about using a bread maker and went to CoffeeCrone.com, now =
here's a way to
supplement my FR-8 and roast larger batches. I picked up a 1600w HG from =
Northern Tools
for about $17 and a Goldstar HB-202CE from the Salvation Army Store for =
about $7. 
Out to the side porch, box fan and SS mesh strainer for cooling, HG and =
BM plugged into 
heavy extension cord, ready to go. Using dough cycle as recommended on =
website, I started.
At 6 minutes BM shut down, cycled power and restarted dough cycle, at 12 =
minutes BM shutdown
again, cycled power, attempted to restart dough cycle, just got 4 beeps =
and nothing. Remembering 
info from website pulled machine apart, unscrewed temp limiter from =
outer housing, pushed
limiter to side above motor, reassembled. Beans at this time had gotten =
into the yellowish stage.
Started BM and HG again, went 2 more 6 minute cycles and BM shutdown and =
beeped 4 times again.
Motor starting to overheat? Beans now at midbrown and nearing first =
crack, powered up box fan, put
BM on top of fan blowing down. Restarted BM and HG, it's working now, =
Hit first crack, continued to 
first snaps of 2nd crack restarting every 6 minutes due to dough cycle =
limitation. Very little smoke
 generated but VAST amounts of chaff from El Milagro Estate beans. Only =
brought out one Oveglove
Opps, forearm burned while dumping roasted beans into strainer on top of =
fan. I tried for C+ to FC 
for the wife, she thought it smelled past that. We coarse ground a small =
sample and French Pressed
it she loves it, I think she was smelling the chaff burning. She liked =
the BM as a bread machine since 
it has a tall skinny loaf shape, I think I need to get another for just =
coffee roasting. I would need to 
rewire the motor for switchable control and remove the thermal limiter, =
maybe add a small fan for 
the motor. That would keep the motor cool as it stirred the beans for as =
long as I not the dough cycle 
would like. Maybe I should get a smaller 1-1.5 lb machine so the HG's =
trigger switch wouldn't melt
from the backwash of heat, and another ovenmitt for my stump.

Mark,
I also read of the shut downs on the dough cycle in BM's, but it has never
happened to us when actually kneading dough for pizza, bagels or using it a=
s
a ROster
Kneading dough takes far more torque than stirring loose beans. Since the
motor never runs during the 325 - 350 F baking cycle, and the baking =
heat
is not blown down into the machine, I think the problem is that you have to
aim the business end of the heat gun right down in the pan and wave it
around just above the beans. Aim the heat right at the beans in the pan so
it is deflected back out of the pan, totally away from the machine and the
motor.
You want to heat  but the beans. In the first 6 minutes, you shoul=
d
have had a chaff storm for at least a minute at that point.The pan has to b=
e
thought of as a heat deflector to confine the heat to the beans and away
from the rest of the machine. Don't defeat your purposes by trying to heat
the Outside of the pan at all. There's no beans out there to roast- only
motors to wreck.
With only a 1200watt HG, I'm all done roasting, cooled off, put away and
brewing sample cups for my wife and me in 30 minutes from the start. You
have more heat than I do, and about twice as much as the baking element in
the bread machine.
You may be blowing heat down where there shouldn't be any heat. Just blow i=
t
down in the pan and it will be fine.
Cheers, and keep on roasting -RayO, aka Opa!

I picked up a Breadman Bread machine from Goodwill and I couldn't be more
pleased with my luck.  I did have to remove a little rubber grommet at the
bottom of the pan but this machine has 2 neat features and 1 just convenien=
t
feature
convenient:
  after taking it apart it looks like there are 2 leads into the compartmen=
t
area, presumably to measure temperature and possibly stop the machine if
it's too hot.  the convenient thing is that either that doesn't work, or as
Ray says, directing heat completely into the bread making pan (which I do)
doesn't heat the outside enough to turn the machine off.  Huzzah!
Neat:
  the dough cycle does a 1 beat per sec turn for the first 3 minutes, and
then goes full tilt a whirl for the next 27 (TWENTY SEVEN) minutes.  That's
more than enough time to make beans flambe if you so chose.
  the dough cycle has a timer on the display.  it's only accurate to the
minute, but your eyes don't have to wander far to see how far along you are=
!
I did 5 roasts in the thing yesterday.
  1) 1# sulawesi goo goo muck (letting it rest so I can taste , can't wait
tosee what i've been missing)
  2) 1# peru norte especial - figured i could replace the pound if i messed
it up as it's still in stock!
  3) 1# costa rica eco brisas Cup of Gold #3 finisher from 2006.  Feeling
brave and the coffee's getting long in the tooth anyway
  4) 1# liquid amber - feeling VERY brave now, nothing can defeat my well
honed (ha) roastmeister skillz
  5) .5# rwanda migongo bourbon - just had to see if this thing can roast
less than a #.  it can, but it's going to knock more than a few beans out o=
f
the park.  i will have to rig a mesh screen to keep these hoppers in the pa=
n
I ended the day feeling quite pleased and noticed that I don't have the
normal headache and shakes I have when roasting over the dog bowl on the
grill for supplemental heat.  i think i might have been getting some low
grade CO poisoning there or something.
Bread machine roasting - good and good FOR you!
