I'm new to the homeroast scene and I found a Poppery II corn popper in =
my mom's attic and started with that.  I have done 5 or six roasts and =
have been pretty satisfied.  My problem is that I wanted to try and get =
a French roast just to see if I could and no luck.  I left the beans in =
for 20 minutes and they never got that dark.  The first couple of roasts =
I every did I weighed out 4 ounces of beans.  The popper says use 4 oz =
or 1/2 cup.  The 4 oz seemed like it was too much so on the other roasts =
I measured out 1/2 cup.  The roast seemed to happen faster but still =
never got very dark.  Is the popper just no able to produce enough heat =
to do a French roast or is there something I am missing.

It could be that it isn't getting hot enough.  You might consider a mod =
to bypass the thermostat.  I have one link for doing this but there are =
others out there if you google the topic.  Here is the one I have, its =
for setting up control of the fan and heaters but it also includes =
bypassing the thermostat.  I have bypassed mine and it will do a french =
roast.  There is some variablity between poppers.  Try this if it =
doesn't work then you might need to search for another popper.

Jason,
Welcome aboard!
What were you doing in your mother's attic?
Try a larger batch size (more beans trap more heat) and if is still doesn't
do it, try another popper.  I have one from a local drugstore (Walgreens -
$9.99, others are cheaper at thrift stores) and it was quite capable of
transforming green coffee beans into smoke.  If you have local thrift
stores, then do search for the venerable Poppery I (and others).
Again, welcome aboard!
Eddie

Jason, I have a PII that I alternated with other poppers. It's rated at
1200watts, same as my heatgun. You have a nice roaster with the P II popper=
.
I "telescope" (3) #303 cans into the top opening so it won't fling beans ou=
t
as it roasts.
They pop corn quickly enough, so it ought to be able to do a job on green
coffee beans. I always started with 1/4 cup or 2 oz vol of green beans, and
they expanded to 3 oz when I roasted to a Vienna, not as far as French.
That's plenty for the 8 cup Bunn drip pot.
More beans = more restriction to airflow, air gets hotter passing the hea=
ter
element slowly. It will roast faster due to the hotter air circulating.
Plus, with too many beans, they are pretty jammed in and can't circulate.
Leads to uneven roasting.
The tangential airflow ports should cause a counter clockwise rotation of
the beans. If you tip the roaster (15- 45) while the beans are swirli=
ng
around, they'll mix it up pretty well.
Maybe there's a reason the thing was stowed in the attic. Maybe it ate too
much popcorn chaff back in the day, and it's fairly plugged up. You can set
up a shop vacuum to blow backwards through the popper and dislodge any dirt
or chaff. If you get clouds of chaff, you might want to vacuum the motor
directly. No problem- It comes apart easily if necessary.
There are three #2 phillips head screws (2 in the front, 1 in the back
center) under the top lip. Take them out, and you can remove the top rim of
the popper. Compress the line cord strain relief vertically with a pair of
pliers and wiggle it out. Take it off the line cord and set it aside so you
can reinstall it afterward.
At this point the blower/ heater in mine was totally loose and I could brus=
h
and vacuum out the motor as necessary. If yours is not loose, there are two
more screws in the 1.25 inch deep recesses in the bottom. None were ever in
mine but it was designed for them. Crazy.

Reassembly is the reverse of disassembly! Forget not, lest ye be known as a
Forgetter like me.

A few questions for ya.  What is the ambient temperature you are roasting at,
and are you using the plastic shroud that redirects the popcorn into a bowl?
If its too cold when you are trying to roast, the popper is probably having a
hard time sufficiently heating up the air as it passes through.  If that is
the case and you use the plastic shroud I have something you can try.  Find a
cardboard box that is big enough that the popper fits easily inside.  Next,
position one of the cardboard flaps so it presses down on the plastic shroud. 
What you are trying to do is redirect the hot air that comes out back toward
the air intake of the popper.  This way the popper doesn't have to heat the
air as much to reach a good temperature.  Just be careful because the chaf is
going to recirculate too.  I built a chaf collector in the cardboard box.
I also modified mini similarly to the engadget link, so that may have
something to do with it to...

Jason,
It sounds to me like your bi-metallic thermal sensor is doing it's job and
preventing the popper from , what it senses as, getting too hot. It's an
easy fix. You just need to open up the popper, and bypass the sensor,
allowing the poppers heaters to be always on. 5 minute fix, if you don't
mind getting your hands dirty, 10 if you do ;-)

Thanks everyone for the ideas.  I think a little modification is in =
order.  It sounds to me like bypassing that thermal sensor will do the =
trick.
