Topic: Behmor vs HG/BM question (6 msgs / 132 lines)
1) From: Patrick R. Sklenar
Are there any other HG/BM roasters who have gotten a Behmor?  Do you 
have any difficulty detecting the "Cracks"?  While the Behmor IS quiet, 
being fully enclosed, I seem to have more difficulty hearing the First 
Crack sounds than I do from the open throat of the bread machine.
Has anyone else noticed this?
In fact, I don't think I've heard what I'd call an actually "rolling 
first crack" once yet.  It always seems so slow and muted compared to 
what I'd previously heard.  And last weekend, it bit me ... I was 
waiting for a real rolling crack on the last of my 06/07 batch of IMV 
... I was hearing the occasional crack, but nothing like a constant 
"popcorn popping" sound like I get from the HG/BM, when all the sudden I 
heard a couple of higher pitched cracks which quickly crescendoed into a 
rolling Second rack.  I hit COOL almost instantly, but still ... within 
four days of the roast, oil spots were forming on the beans.  Definitely 
took that roast too far.
I'm also having a little more difficulty judging when to stop the 
roast.  With the HG/BM setup and my cooling fan, I could stop a roast 
within 15-45 seconds if I was ready (fan already spinning, etc).  I'm 
not trying to learn when to hit COOL on the Behmor, but my difficulty 
with discerning the Cracks ... well, I'm learning, but ... :)

Your experience mirrors mine almost exactly. Difficulty hearing first 
crack at all. Never having a full rolling crack.
I have low voltage in my house (105 when the Behmor is running) and just 
thought the Behmor didn't have enough heat to push the beans into a 
rolling 1st.
I only have about 8 roasts on the Behmor and have my eye on a Staco 
Variac to bring up the voltage.

Thanks for the confirmation Scott.

hmmm ... Considering that my "problem" is that I've over roasted most of 
my Behmor Roasts so far ... I never even thought that it wasn't getting 
enough power. :)  Plus the house is only 5 years old ... no, wait ... 
2/15 will be six years since I got the post-construction CO.  Wow!  THAT 
is hard to believe.
Anyhow, I can put a multimeter on the other socket of the outlet when I 
have the Behmor running ... will that give me a viable voltage reading?  
Or do I need a Kill-a-watt that I can put inbetween the Behmor and the 
socket to get the actual voltage available to the roaster?

Multimeter will work just fine.

The low and sagging voltage at your outlet is not caused by the Lack of a
Variac.
You're right- the 105v robs 30% of the heat output of the heater on 125v, so
maybe the roaster problem.
The real cause may become obvious by the surprise location of smoke and blue
fire.  You have a meter- never mind how accurate it is. Establish a good
independent ground and measure between the ground and the Line (Narrow
blade), and ground to Neutral (Wide blade).
Subtract the two voltages you measure, and that's what is available to the
roaster.
Another thing you can do as an easy check would be to plug in a vacuum
cleaner somewhere else in the house and turn it on. Listen for it to change
sound as you turn the roaster On and Off. Assume you roast in the kitchen
and run the vacuum from a bedroom or bathroom.
If the vacuum runs slower or faster when you turn the roaster On, you might
have weakfish house wiring. Call Sparky. If it doesn't change at all, and/or
your TV or computer monitors don't shrink down, you're getting low voltage
power to your residence. Call Public Service to solve that.

Just another opinion- safe is better than sorry...

The utility company is only responsible to deliver the legal minimum 
voltage to the bottom terminals of the meter.  Depending on their 
charter this can be surprisingly low, call them and ask.  The usual 
source of this low voltage at an outlet is inside the house and the 
customers problem.  Check several outlets, if you get the same readings 
then it might be a utility problem.  Or at the distribution panel.
