Lately i've been having days of "i just can't get a good shot pulled---what=

Experiment with Breadman TR441 Breadmakin=
g Machine. 
Goodwill yesterday, $1.50 for a NEW machine. 
I have =
2 bread machines and this one has a much smaller footprint. 
The bowl =
is a square cyclinder, and the machine is a 500 Watt unit. 
The only t=
hing missing is the stirring paddle. 
I took it apart in just a few mi=
nutes with a Phillips screwdriver. 
The first task was to attempt to m=
anually control the motor with a 
switch. 
After much searching, I a=
ccidentally found a very easy way to determine 
what 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 l=
eads. 
I measured the AC Voltage between the Black cord wire and each =
of the 3 
motor contacts. 
One went from zero to 120.  That's the on=
e. 
I turned off the machine and I connected a wire between the 2 cont=
act 
points. 
Of course, the motor ran contunuosly.  Done! 
Nex=
t, what temperature would the baking chamber go to if the 500 Watt 
heate=
r 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 consi=
der roasting in a modded 500 Watt bread maker with no 
external convectio=
n oven or heat gun as a source for additional heat. 
After, the Hi tem=
p test, I ran the motor again to check if the bearing 
was still OK. The =
motor turned smoothly and quietly. 
BTW I intend to keep the timer fun=
ction as designed.to time the roasts, 
not to control 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 he=
at gun to blow out the chaff and for cool down. 
Outside of course. =
What fun for $1.50! 
I hope that this information will encourage=
 others to consider using a 
modded breadmaker roaster. 
Update:  To=
day I wired up the machine to 2 lightswirches mounted on the4 front of the =
unit.
Left for motor and right for heater.
The Breadmaker timer still o=
perates and I can time the roasts to the minute.  (no seconds).
Next, I n=
eed to fabricate a stirrer and mod my heat gun to blow cold.
