Happy New Year to All!!
I spent my New Years Day morning doing some roaster mods.  I have a
good friend how is a Blacksmith / Coppersmith / and owns his own
Heating and Air company.
 The Jobs on deck were:
One - build duct work to carry the smoke out the window
Two - build a funnel to use to dump the beans into the roaster.
Here is a link to the photobucket album:http://s90.photobucket.com/albums/k272/why1504/The duct has a lip on the top edge which slips over the top on the
back of the roaster.  Very Convenient as I can slip it on and off when
ever I move the roaster.  We soldered the 3-4 inch adaptor to this
place.  The flanges are hand hammered.  It worked well enough that the
wife let me roast inside today.
The funnel is hand made out of copper sheet.  Once laid out we cut it,
bent it up soldered the seam, polished and washed it.  The shine will
dull quickly.
Anyway, you are all welcome to the pictures and ideas.  Sorry we
didn't make any drawings!!

Happy New Year, to you, too, Hank!
 
Nice work!
 
Thanks for keeping us posted on your Quest quest! Are you keeping notes on control settings, bean-load, bean-type, and results? When a particular roast batch hits First Crack, how do you "hit the brakes" to extend First and the interval after it and before Second?
 
I am really hoping someone will host a Quest event somewhere in the San Francisco Bay area!
 
all the best, and,
 
Happy Roasting,

I find that for a given bean I hit first crack at about the same
temperature every roast -- usually around 200C with the standard
thermometer in the standard location.  So when the thermometer reads
195C I reduce the current by one amp to slow things down.

Robert,
Thanks for the positive comments. 
Yes, sort of. I purchased an Omega Data logger and K thermocouples which I am using. There is a piece of software out there called Artisan that allows you to plug it into a mac or PC. I have it downloaded but am struggling with some communications settings. However, I am close.  If I add a PID I will have a full blown computer controlled roaster. 
In the interim I am using an iphone app. Roastmasters. I have yet to determine how to export my data yet. It is OK. There are things amour the app I don't like. 
My next step is to get Artisan running and then buy a PID. 
I agree with Steve on 200 but it depends on the bean and the bean load. I have seen C1 start at 185 and 210. 
I have run roast fast and slow, start fast end slow. 
I do like the roaster. 
Thanks,

Look at the app for Mac/win/Linux called Typica. It's pretty full featured, but it requires one of two very specific data loggers. There is a way to set it up for manual logging. 
It also does bean management and can track cupping notes. 
It does require a db backend (also free) that may look intimidating but is not too difficult to setup. http://www.randomfield.com/programs/typica/Hths

Keep in mind that "a pid" is pretty broad. There are lots of different types of PID units with different features.
I was lucky - I found a really sweet PID controller that can store 4 different 8 step profiles. I was gonna roll my own PID with a microcontroller, but this ended up being cheaper, but only because I found a great deal (auction for a unit with a low price, and a missing part of the part number).
I also have another PID that is pretty dumb - it's good for holding a temperature, but not so much with the ramping and soaking.
