Subject: +Experiment=
 with Breadman TR441 Breadmaking Machine.
Experiment with Bre=
adman TR441 Breadmaking Machine. 
Goodwill yesterday, $1.50 for a NEW =
machine. 
I have 2 bread machines and this one has a much smaller foot=
print. 
The bowl is a square cyclinder, and the machine is a 500 Watt =
unit. 
The only thing missing is the stirring paddle. 
I took it =
apart in just a few minutes with a Phillips screwdriver. 
The first ta=
sk was to attempt to manually control the motor with a 
switch. 
Aft=
er much searching, I accidentally found a very easy way to determine 
wha=
t 2 points to connect. 
I started the machine and like all breadmakers=
 that I have used, it 
pulse turned. 
The motor is connected to the =
control board with 3 leads. 
I measured the AC Voltage between the Bla=
ck cord wire and each of the 3 
motor contacts. 
One went from zero =
to 120.  That's the one. 
I turned off the machine and I connected a w=
ire between the 2 contact 
points. 
Of course, the motor ran contunu=
osly.  Done! 
Next, what temperature would the baking chamber go to if=
 the 500 Watt 
heater coil would be on continuously? 
I wired up the=
 coil to 120 AC and I waited 15 minutes. 
Surprise!  450 HOT degrees! =
IOW We can consider roasting in a modded 500 Watt bread maker with no=
 
external convection oven or heat gun as a source for additional heat. =
After, the Hi temp test, I ran the motor again to check if the bearin=
g 
was still OK. The motor turned smoothly and quietly. 
BTW I inten=
d to keep the timer function as designed.to time the roasts, 
not to cont=
rol the unit. 
The motor control bypass should not affect the machine =
(nor will the 
heater bypass). 
A BM has a much stronger motor than =
a SC and I believe that the chamber 
shape makes for better roasting. 
=
I intend to use a heat gun to blow out the chaff and for cool down. 
=
Outside of course. 
What fun for $1.50! 
I hope that this info=
rmation will encourage others to consider using a 
modded breadmaker roas=
ter. 
Update:  Today I wired up the machine to 2 lightswirches mounted=
 on the4 front of the unit.
Left for motor and right for heater.
The Br=
eadmaker timer still operates and I can time the roasts to the minute.  (no=
 seconds).
Next, I need to fabricate a stirrer and mod my heat gun to blo=
w cold.
