Hi All
I selected the SM Ethiopian Kochere and had some sent to the house to try.
I've been having trouble getting a decent cup from the many different roasts
I've attempted.  C, C+, FC, FC+.  Nothing very good seems to come out.  I
believe it is temp related.  Recently, the outside air temp in town has been
very high lately and my roasts have been going faster and faster.  I have
tried many things to slow them down:  Less beans (from 90g down to 72g),
extension cord, remove chute, stir and lift...nothing seems to slow it down.
My unmodified WB1 seems to get hot and stay that way.  My first roast of the
day will go to 5-7min, but unless I wait half the day for cool down of the
WB1, I can't get time time much past 4:38 (edge of 2nd crack) which is WAY
too fast for good coffee - IMHO.
 
Anyone?

IIUC you have a Westbend Popper 1, the most easily modifiable popper on
earth. If you want control of the roast TAKE control of the roaster. Split
wire the heater and fan for independent voltage to each. Then control with
variacs, 10A or better for heater, 1A or better for fan. There are numerous
websites with detailed P1 mod how to's.

An easy fix may simply be to get a decent little fan (like the $10 table top
vortex fans on sale at Target) and blow air at your machine while you
roast.  I used to do this with my FreshRoast to help it cool faster, and it
worked really well for me.  Of course the best solution would be miKe's
below, should you be so inclined!

Thanks for the reply's.  
Mike - I have seen the many sites with varying amounts of modification
details and can say up front here that I am not a sparky.  If it is
mechanical, I can deal with it, but not with those sparks flying around.  I
want to live long enough to see my kids turn at least 10yrs. Old.
Anyway, 
Floyd, the fan cooling option my be an easy fix for now.  If these WB1 were
not going for $50-75 dollars on eBay these days, I wouldn't mind trying to
modify one, but to replace if after I've hacked on it for a few days is not
in my budget right now.  Some of the mods I've seen show the fuse or thermo
bypass being soldered back together - can this mod hold up to the temps it
will see?

Coffee roasting temperatures are around 200F below the melting temperatu=

of Sn-Pb solder (the original solder type). The use of that solder has
fallen out of favor in copper plumbing.
Smart money doesn't use >any< solder around heating devices. Lacking good
design, use high temperature butt splices and fiberglass tape or ceramic
wire nuts instead.
2 Hints:
A.- If you are mechanically inclined, just set up wire routing, connections
and insulation to avoid bare conductors ever touching anything. Then you'll
never have the excitement of Blue Fire and Ozone. What a dull existence.
B.- Being so inclined, do tell when you plan to introduce your drum roaster=
.
Drums, we have but the mass produced drum roasters for home use are really
sad sacks.

The key phrase in your post is "unmodified". Your predicament is a perfect illustration of why there are "modified" poppers. You can roast ok coffee in an unmodded popper, but for optimum performance ... well, see MiKe's reply to your post.

Hi to all,
 
Thanks for what I know must have been agonizing for all of you regulars on
this list - hearing about my popper woes and all.  
 
I have many different types of poppers around the house.  Some I had before
finding out that coffee could be roasted on a fluid air bed, some I bought
after reading posts from forums like this and websites.  I only asked about
the Kochere because it isn't coming out like my very first batch of home
roasted beans - which was very rewarding!  That first batch I roasted in my
Nostalgia Style Popcorn Maker (terrible at making popcorn).  This was one
that I bought from Rite-Aid for my sons birthday a few years back (he's 7).
It holds a very small batch but roasted up just exactly as was described on
many a website or u-tube video.  I simply filled the lid with beans, poured
them in and flipped the switch (yes - it has an on/off switch - no
modification necessary)  I took a long temp gage from my back yard turkey
cooking pot (Wal-Mart) and stuck it down inside the chute to check temps.
The bean temps were rising and right on the money - 1st crack at the
appropriate time, the color, the smell....  Dumped them at around 6-8min and
cooled them by tossing them in two stainless colanders, rested them for a
day and ground them up - nice - simple and no mods necessary.  The only
drawback was the small batch size.  I guessed that if I could roast this
good in the NSPM, just think of what I could do in a WBII or WB1.  Now I
have a shelf full of poppers and a wife looking at me like I'm spending the
money she uses to feed the children.
 
So I moved to the WB1 - so far I have managed only fair batches of drinkable
coffee.  Not like when I used the NSPM.  I suppose I'll have to take a class
on basic electrical do's and don'ts  in order to improve my hunt for larger
batch roasts and gain a suitable reputation on this list.  Maybe I should
just buy Tom's roasted coffee and loose the urge to hunt for more poppers at
thrift stores - I guess that's  just what happens when you get into this
hobby.  Now I suppose I'll have to buy a Rocky to grind with...$$$.
 
Thanks for the comments and happy roasting/drinking/grinning =)

I have a West Bend Poppery 1 - and here's my mods...
I place the front edge of the base approximately 1/2 inch elevated, so my
beans get some help with the first tumbles...  then I roast...  I lower the
base to flat once the beans start in first crack...
I love my coffee...

Don't want to be working too hard!

Chris,
If this sounds like too much, a simpler mod is to install a switch in line to the heater coil.? Not nearly as precise as Mike's method but I used it for years on my Poppery II.?? 
The basic idea is that you can switich the heat off during the roast to control temp.? I monitored temp with a deep fry thermometer.? as the temp rose, I would switch off the heat for a 10 count then back on.???For Yirge, I would strech out the time the?beans went from?300-350 by switching the heat off 3?times (at 300, 320, and 340 roughly).? This?seemed to let the green flavors burn off without sacrificing brightness in the city roast.? I would also switch off the heat once or twice between 350 and first crack.???If you are going?for FC+ or darker, you can also lengthen the time between 1st and 2nd crack the same way.
Here's a link?that shows?the?basics of popper internals.?http://www.homeroaster.com/geekmod.html?Got if?off?the sweet maria site.??The 2 tricks are to figure out the correct wire to the heater and to make sure you buy a switch that is rated for 12-15 amps.? Also, if you roast?to 2nd crack often, you may want to look at the part about tweeking the thermostat on the popper.
Dave?
