Topic: Late to the party (used to be Re: SC/TO) (14 msgs / 361 lines)
1) From: Ann Vanderlaan
Sorry to come late and uninformed to the discussion.
Can anyone point me to plans or URLs with SC/TO construction diagrams?
SC/TO = Turbo Oven/Stir Crazy I assume?

Hi Ann,
Try this page:http://turbocrazy.atspace.com/index_files/project.htmMine's built just like that, but with a different brand of  TO
(turbo-oven.)  The few changes I made include using fewer threaded bolts
to hold the chaff ejection chute open -- two will do -- and
disconnecting the SC (Stir-Crazy) heating element.  Like I said in an
earlier post, I'll put the lower element on a switch on the next one.
One other detail:  I pop-riveted three aluminum "fingers" to poke up and
out over the top of the spacer ring.  They keep the TO from sliding
around.
It's worth the effort!

Ann, you can get design specs and more info from a search for "SC/TO coffee
roaster." -ro

Go down this page a bit and you will find all the information you need,
maybe too much. :)http://www.coffeegeek.com/forums/coffee/homeroast/232705#232705On 5/29/06, raymanowen  wrote:

Tom in GA,

That's a great link. When I started research from Sweet Maria's I ended
up with a dead link in the WS domain. Unfortunately as a nerd I got 
distracted by the geographical location of such a domain. :) The chaff
chute seems to be a very elegant solution to my biggest concern. As a EE
I would probably also switch out the SC heating element. What brand of
TO do you use?
ro,
I did google for "turbo oven coffee roaster" and ended up with a large number
of circa 2000-2 blogs angsting over chaff and such. But no pix. When the SM
links came up unresolved I felt like the list was the best place to ask.
James H.,
There is no such thing as too much info. I hadn't seen this thread at coffeegeek.
It also has the link Tom cited. I must have petered out in my google ardor. :)
Scot M.,
Great thread Scot. Now I know how to avoid center shaft meltdown, and have an
easy method of thermometer mounting. Ya know, we do not have these kind of 
problems in the oil-drilling industry!
Many thanx gentle folks. Now a question. Is anybody concerned about degradation
of the non-stick surface coating in the SC? We are certainly operating out of
spec for the surface I believe.

IIRC, Teflon is a problem when you get it hot. It starts to emit a toxic
gas. Techs soldering around Teflon insulation (about 700 degrees Fahrenheit)
work on a laminar flow bench -- air blows across the surface of their
workbench to carry away any gas generated.
I did a google for "teflon heat toxic;gas" and got lots of hits. This was at
the top, looks like a "scare site", but maybe a good starting point:http://tuberose.com/Teflon.html.I can't vouch for the veracity of the site,
but roasting temperatures are certainly on the edge of what is a problem
with Teflon. It would be prudent to have good air circulation.

Michael,
Just my opinion, but the base of the StirCrazy probably doesn't get as =
hot roasting coffee as it does popping popcorn.  That's especially true =
if the base heating element is disconnected.  Abrasion by the stirring =
rod over time would be the thing I'd worry about.
From the FAQ at Westbend;
Temperature
Q. What temperature does the Stir Crazy® get to during use? 
A. - The base of the corn popper will heat to approximately 450°F to =
520°F during use.

Is anyone using one of these indoors??? Way too much smoke for that.

Starting at about 2nd crack the beans generate heat too. Popcorn never gets
to this stage, it is done at  first crack.

I use mine indoors. No problem at all. All I have is one of those bs
circulation vents in my oven hood.  The smell lingers for a couple hours but
it is not too bad of a smell really so I don't mind. The chaff collects in
the sink. My wife only has a problem when I roast in the middle of the night
after she is asleep.

One could always go back to what plumbers did before Teflon tape: 
wrap string around the threads. They also used a compound w/ the 
string, but I wouldn't think that would be necessary here...
