Topic: Turbo Stir-Crazy (11 msgs / 276 lines)
1) From: prentice
Well, I've always roasted with poppers, but today I cobbled together a "Turbo
Stir Crazy" unit and gave it a whirl.  I must say, I am impressed.  
I think I can easily roast a pound or more each load and the temperature control
on the Turbo top will apparently allow some profiling, albeit totally manual. 
It's a lot quieter than a popper so I have NO trouble hearing every little
crack.  It's also pretty cool watching the chaff spin around!
I recommend this method to anyone who has a Turbo-type oven sitting around.  Be
careful, though, you can get to third crack a lot quicker than you'd think! 
Also, be sure to replace the nut that holds the stirring wire with a 1/4-20
wing nut and a washer.  It just can't take the heat from the turbo top.
Another thing I found interesting.  The Stir-Crazy I have is self reversing.  If
the stirrer jams, it reverses itself.  Does anyone know if this is the norm?  I
know I've heard of people having problems with these things jamming but I just
don't see how it can happen in this one.

Prentice,
My Stir-Crazy is also self-reversing.  Do you also have the big, 8-quart
model?  I did have some minor jamming problems until I bent the ends of the
wires up just a touch.  Someone else mentioned that they've added rollers to
the ends of theirs.  Of course, I primarily use my Rosto now, but it's
*good* to have a Turbo/Crazy assembly as a backup, and/or if I need to roast
more coffee than usual.
Enjoy!

Those of you who have used the Turbo Stir Crazy, did you modify it in any way? How long does one pound roast take? I tried this about a year ago and I think I had a bad unit (pulled it out of an attic) because I let it go for over an hour and never even reached first crack. Of course, all of that coffee was ruined, but hey, experiment and learn, right?

I made some modifications to mine.  They included methods to stir the beans more effectively and protect the central nut from heat damage.  You can see my modifications herehttp://www.bish.ws/coffee/TurboCrazy.html.  My motor self-reverses as well.  It usually happens only at the beginning of the roast before the beans have lost some of their density.

Hunt,
What you may have is just the Stir Crazy part sans the Turbo. If so, you 
might run into that problem. It's a bit underpowered for roasting coffee, 
hence the addition of the Turbo (cylindrical glass convection oven)...
Most of these ovens go up to about 450F, although there are a few which 
don't. In other words, there is no such product as a TurboStirCrazy.. It is 
a hack....
Ciao,

Haven't tried a pound yet, but can't imagine it taking over 30 minutes.  You
MUST have the Turbo oven top, though, because the standard stir-crazy won't get
hot enough to roast.  (At least MINE won't.)

To get the orginal nut off, do you unscrew it clockwise or counter clock wise?
Thanks

If I remember correctly, I half melted the centre nut on my first pre-modification attempts at roasting with it... but it still unscrewed OK :)  Standard anti-clock to undo, so that means there's nothing fancy about it's replacement.  I don't know the exact thread size... I just had something laying around that fitted.
Cheers

Ah-ha! Thank you. I wasn't quite making the quantum leap with the "Turbo"-ness of the modification. I think I may try to scrounge up the parts of this Frakensteiner

  damage.  You can see my modifications here
 http://www.bish.ws/coffee/TurboCrazy.htmlJust checked out the link and looked at the
pictures... impressive. That's very close to what I had in mind when I
started playing with this idea, but I would have no chance of getting
to that level of implementation because I'm not very mechanical guy.
(Electrical - sure, chemical - sure, but not mechanical) What I ended
up using was more radical replacement of the nut, and cake ring
instead of the dedicated collar.
To add to the original question, the Stir Crazy has a thermostat under
the heated plate inside, and I don't think it'll roast coffee.
