Redneck Roaster.http://www.surfingsmarter.com/coffee/This was a lot of fun to do and well, it proves you CAN roast a pound or 
more of coffee for under $100 bucks.

Drop-dead gorgeous.
What kind of chaff issues do you have?
My first dilemma would be figuring out a way to TC the thing. Can you hear
the cracks OK?
Seriously, that's a gorgeous contribution the the range of options availabl=
e
for folks to roast inexpensively. That oven was a heckuva find.

a bit of the chaff drops to the bottom of the roaster... thats another 
thing about it... it has a pan in the bottom that you can pull out, kind 
of like a dropping pan.   For cooling the beans you can do one of two 
things...  1.. hold the entire can up to a fan or whatever and cool it 
in place or 2... pour the beans into a different cooling device.... 
there is a bit of chaff left in the cooking chamber .. but if you use 
any kind of fan for cooling outside the roaster it will blow the chaff 
away...... note to users... kitchen is probably not the place to do this at.
Another thing that is kind of cool... the thing occasionally.. maybe one 
a minute or two.. drops a bean out onto the pan.... while you can shine 
a light into the oven glass and into the roaster to see the bean 
status.... seeing one sitting plain open gives you an idea how far along 
they are.
THe beans will slide a bit, but because of the 'gap' that is left in the 
screen, it causes like a stair or whatever you want to call it . so each 
rotation the beans will 'grab' and give a good tumble in the pan.   no 
need for vanes or stuff like that to stir them.
theres kind of a swoosh  / swoosh /  rattle sound when the beans hit the 
edge and tumble a bit once a revolution.... the rotisserie turns about 4 
rpm or so that I have seen.
you can hear the cracks.  smell the smoke and see the color..
I was thinking of TC myself but well.... i wanted to keep it cheap 
first.. so that folks can see that yes you CAN roast 1 lb on a budget.. 
and geek it up as you want / are able to/  have the money to..
............
One last thing,  I plan on leaving the web page up for an educational 
tool?  if anyone thinks of something else I should mention or add to 
what I have, please let me know, as I want to make it as easy as 
possible for others to not only make this thing if they want, but see 
the 'mindset' behind it.and hopefully we can inspire others to make 
something different themselves.

Finally!! I have been touting this as a possible method for years. I 
only roast a half pound a week, so I never had a reason to actually 
put one together.
The oven which seemed the best bet to me was the Ultrex. You can find 
them new on ebay starting at about $60. The neat thing about the 
Ultrex is that it comes with a rotisserie basket....No need to 
fabricate your own. I don't know if the rotisserie can run at the 
same time as the fan but, if not, I imagine your switch fix would work...
Good job, Aaron...

Well Done!
And that's for the web site as well as the roaster.
Enjoy!

Similar electric rotisserie ovens have been around since the 1950's and
likely before that. There is nothing new under the sun.

Yeah, but what anything that's been around a long time needs is some
inventive fool who loves coffee staring the thing down face to face for a
few minutes until his eyes brighten and his smile broadens and he starts
nodding while reaching to take the thing off the shelf, go buy it, take it
home and start that ol' innovation game.    ;-)

9) From: Aaron
Angelo, hmm I wish I would have seen that before, I might have 
contemplated it.  Trust me I looked at a lot of options for the basket.  
Big issue with the basket though is the hole size.  Peaberry coffee is 
small.  Some of the other coffee's  like the burbon for one example, is 
small.   Have to be careful we don't get a basket which will let the 
beans fall through.  Do you know by chance if the Ultrex basket is small 
enough to hold the beans in?

So we are fools now? :-)
BTW I have been drum roasting in an electric rotisserie oven for about 3
years. It is a Maxi-Matic. Small amounts are ok indoors but a pound of
coffee will make a lot of smoke and smell, so adequate ventilation is
needed.
I have two 1950/1960 era rotisserie ovens that I may use for roasting, with
a few improvements.

With that, Ken, and I think Scott's recent SS Thermos + Halogen roasting,
I had an odd thought the other night watching the Food Network.  They were
showing a company mixing micro-chocolate chips for drinking chocolate. 
They appeared to be a rubber or plastic cemet mixer looking thing.  So,
has anyone thought about larger scale roasting with an electric cement
mixer?  Cleaning would be a challenge, if it's used.  Also, how to heat
the beast would be difficult as well.  And what the heat would do to the
rest of the rig, etc.  But, it was a thought.

Aaron,
I honestly can't remember, and looking on ebay came up with 
nothing....While looking, I see that Ultrex has a pizza carousel 
(item#'s 4457864153 & 4458865534). Wonder if anyone has tried 
affixing some sort of vanes to this so that the beans get agitated 
evenly. Also wondering if this thing gets hot enough. If so, this 
could be a simpler SCTO...

Someone markets something like this one Ebay.  It's an RK style drum that i=
s
made to fit the Ronco Rotiesserie ovens and maybe some others.  The same
seller also sells BBQ drums.

Don't mind at all Ed.  That's what I put it up there for.
The more information we can give to people, the more all of us benefit 
in the long run.  I probably will add a links page as well in the near 
future here, as I play with the thing a bit more trying different ideas etc.
thanks

Okay Aaron,  Lets hear the roast details-  times, how-to, how is it working so far?  Inquiring minds want to know.  Well, at least I do. -Tom

Aaron!!!! Your "Redneck Roaster" is an awesome and inspiring example of
innovation.  It looks like it would be easy and fun to build.  We're
interested in hearing some roast results.  I suppose there are the inherent
issues of trying to get a thermocouple inside a rotating drum :-(

Neat mod, Aaron..  I might try it, though I go back and forth between this
one and the bread machine mod I've seen around.  It looks like the
rotisserie could be pretty easily modded to make off-axis rotation..  Just =
a
thought.  Also, are you going to TC it?  I'm wondering if some other
measurement system might be better, such as a thermistor, which can develop
a larger signal, or maybe even IR so you wouldn't have to worry about the
whole wiring problem with instrumenting a rotating drum.
Definitely waiting with baited breath for some stats on the performance of
the machine, including heatup and cooldown rates..

20) From: Aaron
Ill get some roast profiles up once i fix a tiny issue i found with the RR.
it seems with very small beans or small peaberries, they will somehow 
manage to sneak into the tiniest openings and work their way out.  I 
believe i have the problem solved here with just a piece of metal that 
will pop right out when you do the pour so the basic working theory will 
be the same.  I just want to test it before i give results.  It won't 
really do anyone any good if I say a pound of coffee roasted in   XX 
minutes when a quarter of it might endup on the floor of the roaster.
This was not a problem at all with the larger beans, just the very small 
ones, but still, is an issue I want to address first.
Aaron

21) From: Aaron
steve as far as instrumentation and temp readings i was thinking of that 
but to keep it simple.  They make thermometers that are offset at a 90 
degrees axis.  In the navy we used to call them lollipops because it 
looked like a big lollipop on a stick.  Now they are metal / glass and 
steel and you can get them to withstand temps up over 1000 degrees.  
Even the glass will handle HOT temps,  I use one in my smoker and 
sometimes when i am burning off excess grease that thing will hit 800 
degrees.
anyways.  I can mount it right to the spit itself, tie it down with 
metal straps or whatever, and it will rotate with the drum and you get 
to read it 4 times a minute as the face goes roundy roundy with the rest 
of the drum.  The temp will the temp essentially in the middle of the 
drum.  while not actual bean temp can give you an idea and with some IR 
shots on the beans themselves for a temp reading , if I need to do an 
'offset' that can easily be done with a cal screw on the thermometer or 
just brain it out. ie  subtract 25 degrees from the reading.  It should 
be pretty linear at that temp range.  If i get a thermometer with a thin 
shank on it it will have a pretty quick response time so you are not 
waiting 5 minutes for the temp to 'settle out'....  also as with 
mechanical devices, the rotating and the tappity tap tap of the beans 
falling will give it the tap with the finger to obtain the best reading.

Steven,  off axis.. now why didn't I think of that,  I have an extra 
can, THAT is something to try.  guaranteed bean mixing.....while it is 
not a problem now, a bit more can't hurt any, great idea there.... thanks!!

23) From: Scott Marquardt
I once went on a quest for some high-temperature slip rings suitable for us=
e
with thermocouples, but to no avail. Well, there MIGHT have been some out
there, but it was very obvious which manufacturers I wouldn't bother
exploring further. I remember some military slip rings back in the day,
whose replacements cost a small fortune. I didn't bother looking into those
folks' units.  ;-)
