Nice Job!  I admire the adjustable chaff ejection chute, much more =
elegant than me stuffing a plug in mine.  Great setup.

Great work!
Great set up!
Have you thought about posting on: http://homeroasters.org/php/forum/index.phpWhat you have done would be of interest to lots of folks.
Nice going!

Cool.  I like the stirring arm.  I was thinking of rigging up something 
that would move beans in and out but I think I'll stick with the stock 
one.  It seems to work pretty good.  I'll have to get started on a bench 
like that so I can continue to use it in the winter.  I don't think I 
want to be sitting outside on the patio in the middle of a New Jersey 
winter even if the patio is covered and screened in.
Anyway, I couldn't wait so I have a pot of the Costa Rica SHB Decaf 
brewing now in my KMB.  Should be done by now....

That's one of the best setups I have seen Peter.  My favorite two things you
did was how you setup the spacer to allow for open/close chaff ejection, and
how you did the stirring arms.
Nice work!

Peter,
Really cool setup; gives me some ideas for sure.  I am envious of your setup
as I am moving into a one bedroom apt. and the wife would never go for a
setup like that.  Still, I've got my table and hopefully a balcony that I
can reserve space on.  I like the coat hangar trick.  It might be fun to try
different shapes to see what works best..

Since many of you do not use the heat of the SC, I would assume you 
are only using it to agitate the beans. Might I suggest another 
approach altogether?
There is a device called the Stirchefhttp://tinyurl.com/hhqg2 which 
is a battery operated soup/sauce stirrer which turns at approx. 15 
rpm. I would say that the motor is much more powerful than that of 
the SC, although, I only determined this by hand, rather than reading 
the specs.
The shaft can be inserted through any metal pan. If I were doing this 
I would probably use the aluminum top of a wok that can be had in an 
Asian market for a couple of bucks. Make sure it's the one with the 
flat top. You won't even have to drill a hole. Just unscrew the knob..
You would slide the shaft up through the hole, attach the stirring 
vanes and you're good to go...
You would need some sort of stand or box to allow room for the unit 
to fit beneath the pan...Right now, these things are going for about 
$10... usually you can find them for about $16 on ebay....Oh, and you 
can still use it to stir that chocolate sauce that you're going to 
cover your beans with...
Btw, you could also use this to replace the stirring mechanism on the 
Whirleypop and/or Back2basic stove top poppers. The shaft is a 
standard square metal, so you could get/cut a size that fits exactly...

This thing looks promising, however, I'm confused/intrigued by your ideas of
how to use it.  Are the pans you can buy with holes already in the middle?
Also, it looks like this device actually grabs onto the rims of a pan and
rotates itself...  True?  Does the shaft in the middle on the top rotate?
Seems everyone is using the same pic of it on the internet..  At the very
least maybe this thing could be used simply for the motor inside and speed
control, if it has the square shaft somewhere..

I'm sure I am missing something, but as this is battery operated, how 
would that work in a hot, hot environment?

Steve,
You could use any pan that would fit under the TO. The "pan" I would 
try is a spun aluminum cover for a wok, which has a hole already 
drilled in the center. This is where the knob is located. You just 
unscrew the knob and insert the shaft through this hole. Although you 
are putting the unit through the top of the cover, you will be using 
the cover as a pan by turning it upside down so that the motor will 
be under the pan.
As to it grabbing the rim - this is true when using it as a sauce 
stirrer, or if you use it on the stovetop roasters, but the legs you 
see in the pics fold back into the body of the unit.
The shaft is a separate piece which goes through the body. This means 
it can adjust to different heights/depths, or you could use different 
lengths...
Because this is used UNDER the pan, you would have to have a stand of 
some sort for the whole thing...A cardboard box would do nicely. The 
motor is about 4-5 inches high...
I hope I've explained it better this time
To answer Vicki's question: The motor is under the pan, so there is 
little, or no, heat. Besides, it's made to sit over a sauce pan, 
which has heat coming up to it.... :-)

I see what you mean..  Really cool idea and variant to the SC/TO.  One might
be able to make an annulus of sheet metal as a base use some insulating
spray foam (can this stuff handle oven temps?) to keep the heat from coming
out the bottom.  Also with some dremel work perhaps one could use the wok
itself or another lid as a housing for the TO lid?

14) From: Angelo
I don't think it's necessary to insulate it from the heat in the pan. 
Heat rises so I doubt that much would get back to the motor. And, as 
I said to Vicki, the unit is made to sit over an open simmering pot.
If you decide to use the wok itself, just make sure it's a flat-bottom model.

*"*.* ..nobody thinks I'm tooting my own horn by posting this."*
Hell's Bells, Peter, it's not happening. Toot, already! This guy doesn't
have enough imagination to visualize the necessary mods. I determined to go
from popper #3--> Fresh Roast--> SC/TO, meanwhile building a BBQ-based heat
muffle for the RKDrum.
It made me crazy when the 'Bay prices were going above the Big Box store
prices for both the SC and TO. So I got a SC 8, which makes a great batch of
Kettle Popcorn and quit with eBay. Zum Teufel mit Ihnen.The HG/Mixer Bowl
has been a neat diversion using tools I possess already.
Wow! I managed to actually roast 400g of this Panama Auction Lot - Cafe de
Eleta from '05. MADE GOOD ON TOM'S NOTES, TOO. It made all of First then I
backed off with the Heat Gun from 12:00 - 20:00. Able to coax some 2nd
snaps, I put on the brakes. They felt cold after 20 sec when they were just
thinking of 2nd snap and smoke. Cooling takes longer when it's near 90
degrees. (As opposed to 10 sec to dead cold in cool weather.)
I tried an experiment. I cooled a 40g sample this roast in the freezer in a
Glad container. I thought the roasted beans would tend to fracture rather
than tear if they were very cold when I ground them.
I was hoping for fewer minute particulates. I think I achieved that end with
only a tiny amount of sediment in the cup, without resorting to a paper
filter. With a little sediment, you get quite a flavor show if you drink it
right and swirl it up in the cup before you take a drag.
I was just starting to realize that on the very last pot of Horse I brewed.
That's gone now, so I'll have to tap my Lot 30. That ought to be a real
Fireworks show!

Peter.
First of all, I don't have a dog in this fight. I 
have been reading the enormous amount of 
messages, both here and on Coffeegeek concerning 
the modifications to the SC (a 19 page thread on 
CG) to make it do something it wasn't intended to do.
My first post in this thread was addressed to 
those people who would only use the SC to agitate 
the beans, and NOT use the heating element.
I would like to turn your question around: "What 
does the SC ($25 + $50 for a Dremel Tool+ doing 
surgery + hunting for European rollers and the 
rest of the mod parts) do that the StirChef ($10 
-I got mine for $5 in Jack's 99 Store- + $2.50 
for Wok Cover + free cardboard box for the stand) doesn't do?"
I live in Manhattan and we don't have the choices 
in terms of searching for hardware supplies. Our 
"hardware" stores are "boutique housewares" 
stores that  sell everything (at a premium price, btw) except real hardware.
Another reason I would choose to do it my way is 
that it is much simpler (I'm lazy)..and, it all 
comes apart. The cover can go back on the 
wok...the stirrer can be used on the stovetop 
popper and/or the sauce pot, or just stored away 
(it's pretty compact) and the  TO can go back to toasting my bagels...
If you want to add the extra heat you should 
stick with the SC/TO, but I would prefer the SC/TO...
If I ever get around to putting this together, I 
will definitely put it up somewhere. I don't 
drink enough coffee to warrant doing this, but I 
might make one for my son, who drinks much more than I do...
Ciao
Angelo
Oh, as to the battery vs household current, I prefer one less wire in my=
 apt..

I have a UFO en route.  This "stir crazy clone" has been reported to alread=
y
have the metal shaft assembly.  This means that at most it might need the
heater disconnected or put on a switch, that will cut out %80 of the work a=
s
building that metal shaft was a pain.
Now some of us have started to experiment by "pre-heating" the SC/TO and ar=
e
possibly getting better results than starting cold.  It's too early to tell
if this is just coincidence, or if pre-heating might have some weight to
it.  If this turns out to be true, the stir crazy, and it's clones, provide
the ability to heat from the bottom as well and that might make these a
better option?
However for 10 bucks or whatever the stir chef thingy costs, I would be
willing to try it out.  I enjoy experimenting especially if it's fairly
inexpensive to do so.
I will give a pictorial comparison between the two (UFO and Stir
Crazy--which I use now) when it arrives and my thoughts on it's first few
batches.

My TO, a Decosonic, has burnt my toast to a crisp

using only the TO? What have been the results?

Angelo, you make some great points, and I appreciate your comments.  If a
person doesn't have access to a good hardware store the SC mods, would prove
difficult.  And not everyone finds SC's at thrift stores/rummage sales for
$5 either, nor does everyone have the tools to do the mods.
Steve, et al., I need to add a couple pages to my slide show and will do so
soon, to show my shaft mod.  It costs 49, and takes ten minutes.  It
involves filing down the plastic broken/melted threads of the existing
shaft, drilling it out, and threading into the hole a 'Hanger Bolt'.  The
neat little doohickeys have wood threads on one end, that go into the shaft,
and -20 machine screw threads on the other end that a wing nut goes on to
secure the stirring arm.
