Wrong supposition again, Deward.  At least half the coffee I roast is
Yemen. I started home roasting because the merchant in New York where I
used to buy my fresh roasted Yemen went out of business. The other
coffee I favor is Ethiopian Harrar.
I've roasted some yemen and photographed it to demonstrate the
difference between the matte finish of City roast and the satin finish
of full city, but the digital photos do not reveal what is very obvious
to the eye. (at least to my eye!) This phenomenon is particularly
visible in the FR+.
Since I broke the chaff collector, I have been using the FR+ outdoors,
with a tall tin can chimney (and no chaff collector).  With the
temperatures lately below freezing, the roasts are taking as much as 12
- 15 minutes to get to 2nd crack.  The tall metal chimney allows the
chaff to escape, but dissipates some of the heat, prolonging the roast
cycle. The slower roast time in the FR+ seems to produce a richer more
full bodied flavor than I am used to getting from the FR+. No variac or
other manipulation required (except to reset the timer every 5
minutes.)

Now try manipulating your outdoor temperature (on demand) to get you desired
roast profile!

Now that's interesting.
I have a styrofoam box, slightly larger than my Pumper. You could have one
too; simply glue styrofoam slabs on the sides of the box. The temp outside
is below or at freezing.We know styrofoam acts as a good insulator.
Why couldn't we adjust openings in the side of said box to control the
'ambient' temperature and therefore the time between cracks? - Mike

Actually that's what I did last winter. (I just used a cardboard box, no
top, one side opened like a drawbridge) I find variac and/or trimmer
controlled voltage and fan much better control and you can reduce heater
temperature when it's too hot outside... It's all about what works best for
you to get the roast you want.

Well . . . something very peculair is going on, then . . . because even with my 
failing hearing I typically hear second crack before oil with both Yemen and 
Ethiopian in both a Rosto and a HWP.  Got some Sidamo and some Rimy in jars 
right now, couple of days old, early into what I'd call "second crack", not a 
sign of anything I'd call "sheen".
Which just goes to show . . . verbalized "subjective" descriptions fail 
completely at explaining how you roast . . .

Cathy,
Have you tried using a hurricane lamp glass for your chimney? It 
will  disperse the chaff yet not dissipate as much heat as the can, due to 
the tapered shape which results in a smaller opening at the top...

Another advantage of a hurricane chimney over a can is that the sides flare
out, so the shotgun effect is reduced.  When the beans reach the flare, they
spread out, the air pressure drops, and the beans can fall back down.  Some
people who have made roasters with a long cylinder report that the beans fly
out the top.
