Briefly, it worked perfect.  A roaster that would start outlying 2nd 
at 20:30 (max time) on P1 for 1 lb now does outlyer 2nd at 17:00 min 
with rolling 2nd at 18:30 minutes.
Covered approximately 1/3 of the afterburner entrance vent with heat 
proof aluminum tape.  Pictures will follow...

Tim, if it works, it should be a
simple home fix.  Two screws to remove the afterburner cover, a
little aluminum tape at the edges, and close it back up.  It will be
that easy.  More robust would be a little piece of thin aluminum,
but that would be the "advanced" fix.

Bingo! It's been harder and
harder to hit the first snaps of 2nd on 1 lb.  I was part of the
whole voltage issue discussion and almost called my power company-I'll
clean the side first and see what happens. Looking forward to your fan
experiment-thanks for sharing-there's no way I'd even think to try that
one.

Joe was kind enough to send me a couple preproduction models for 
Chocolate Alchemy and cocoa roasting.  I being the geek that I am
tore it down to frame and dissected it to see how it ticked.
The darker the interior becomes, the colder/longer roast times you 
will see.  The explanation is that the thermocouple is mounted on
the 
other side of the wall on the right back (between a couple of 
mounting screws).  Dark material absorbs heat more, so the TC senses
the chamber temperature fast, in effect cooling it faster. 
Alpenrost 
had this same issue.  General lengthening of roast times as the unit
aged.  Cleaning the back of the right wall is sufficient.
Likewise, I am currently testing something.  There have been on
again/off again reports of "cold" roasters that could not do a
pound 
in the maximum time.  All power consumptions seem to indicate these
roasters are not "cold".  What I think is happening is
that the draw 
fan is pulling a little too much air out (due to natural +/- in the 
fan specs), causing a loss of heat.  Taping over SOME of the after
burner entrance should cut that draw and make the roaster "hot"
again.  I am going to try it out tomorrow with such a roaster. 
I 
will report back.

I do not know, I have not ripped into my behmor yet but, a question.
Covering the afterburner outlet to keep the heat up makes perfect 
sense.  Thing I wonder is,  every so often you have to burn an empty run 
to clean the unit, clean the afterburner etc etc....  is reducing the 
airflow in it possibly going to cause more or maybe even excessive 
buildup in the nether regions of the unit.   Does anyone know any 
definitive answer to this yet or is this something we will discover down 
the road a bit after some trials?  Im wondering if one of those of you 
who have had beta's of this thing might know the answer to this already.
Just playing DA here on design modifications, trying to cover every 
thing that can creep it's ugly little head up into our projects.

Well, her is a thought.  If this "problem" is caused by the slow 
darkening of the side wall next to the TC then it might be better to 
just treat the problem.  The darkening increases the amount of radiant 
energy adsorbed by the wall and transfered to the TC.  Make the side 
wall area color blind to radiant energy.  Either place a polished 
stainless shield with a small air gap over the area.  Or polish the wall 
its self.  This will make the response to radiant energy almost nil. 
The TC will now be responding to convection heating from the air in the 
chamber and conduction from the surrounding wall area.

Oh, clarification.  This is NOT meant as a fix for the darkening 
walls.  This is a fix for units that arrive cold that can't seem to 
do a 1 lb in the allotted time.  It appears there draw fan is drawing 
too much air out, and this restricts it  back to design specifications.
As for the clean out, no, I can confidently say it will not affect 
the over condition of the roaster as it is a "fix" not a "hack".  It 
is putting the air flow back to where it should be, not lowering it 
below design specs.

I just got mine at my local Ace Hardware.
I will also post a photo of what I just did to the TC plate.  In 
essence I folded over a small piece of scrap metal I had (to create 
an air space), and taped it in place with some of said aluminum 
tape.  Result? Compare:
Stock P2 1/2 lb beans
1st 13:30
2nd 15:30
With metal buffer
1st 8:30-9:00
2nd 13:30
I am making no claims as to whether it is good or bad, but just that 
it is simple way to mod the roaster for those desirous of a shorter 
profile.  OTOH, in a fast 3 person blind smell off fresh out of the 
roaster, the shorter profile got the nod.  I will try and report back 
in a couple days after it has rested.

I guess I have a good one.  I like to pre-heat two minutes and cool two
minutes before loading.  I took a pound on P1 with 30 seconds plus added to
a very fine Vienna roast.  For my second roast I did a half pound on P2 to a
perfect city plus in 15:30.  I keep my roaster squeaky clean.  I vacuum it
out after every roast and clean it with formula 409.  It is a wonderful
little roaster, and very flexible for half pound roasts.

I think good vs bad is kind of harsh.
 From the best I can tell, most components (fans, heaters, resistors, 
motors, etc) fall on a bell curve of specs and a few draw a touch too 
much.  I recall a conversation with Joe about how much of a razor's 
edge he walked getting enough draw to get smoke suppression but not 
too much so as not to be able to do a pound.  From the comments I 
have seen, I would swag a number of 1-2% that are "too cool" meaning 
they can't reach 2nd within the allotted parameters.  Right in line 
with the bell curve IMO, and certainly not a "bad roaster".  There 
are just as many that run "a little hot" and don't quite do the smoke 
suppression great (too much air flow would mean cool 
afterburners).   How many I-roasts were "cold" when they first came out?  30%?
Just food for thought.

What do you mean by "my TC"?  I was just pointing out where the 
Behmor's TC is and how covering it with a thermal barrier tricks the 
roaster into thinking it is colder than it really is.

Ah, completely different subject.  Yes, I have on 
occasion threaded my own TC through to get an 
approximation of what the Behmor is seeing.  I 
will get a photo of that for you.  Basically, I 
do my best to get the head of the probe right 
where I drew in that little red line on the photo I posted.

Ah, completely different subject.  Yes, I have on 
occasion threaded my own TC through to get an 
approximation of what the Behmor is seeing.  I 
will get a photo of that for you.  Basically, I 
do my best to get the head of the probe right 
where I drew in that little red line on the photo I posted.

Hi John,
 
I may be confused, but I thought you had added your own thermal
measurement probe, snaking the lead through the door and placing it
somewhere near the Behmor's onboard TC, but on the inside.  Sorry if
I misremember.  Must be getting old (actually, AM getting old!) I
understand and appreciate the trick!

What do you mean by "my TC"?  I was just pointing out
where the Behmor's TC is and how covering it with a thermal barrier
tricks the roaster into thinking it is colder than it really is.

There you go - I put the photos in the same gallery since it does
heat up (opposite of a cold roaster) the roaster.

What kind of tape are you using?  I bought the highest rated tape from
my local Lowes.  It is intended for HVAC use.  There is a little bit of
stickiness to it after running a cleaning cycle, and maybe a little
shrinkage (little hard to tell... I didn't measure before putting it
on).  I really hope this tape is OK, as it was rather expensive (~$15)
especially when you consider that only 3 inches or so is needed.
Maybe cutting up an aluminum can is in order?

I believe aluminum cans have some kind of plastic coating on them to 
protect the contents from the metallic taste of the can.  If so, you 
might want to dry run it a shot or two to burn off anything that is on 
it first.

Yep, that is what I used and is in the photo. Aluminum HVAC 
tape.  Technically only rated to 150 F or so, but seems 
fine.  Although mine was like $8.  The aluminum can might bend and 
let gaps in, but then again, might work perfect for an insert.
More to the point, did it work?  Did it shorten your roast 
times?  Can you do a pound in the allotted time?
