Lynne, remember Stu uses his hair dryer for 1/4 pound roasts. I'm not 
convinced it is a great way to quickly cool the pound plus roasts folks 
are doing in a bread machine with an external heat source.

I'm doing 8 ounce batches on the stove. But I won't know what my 'new' 
[translated: very old, electric] stove will produce after my move.
What I've been doing to cool the batches is to first use the basket fr. 
an asparagus cooker over the sink. Try to shake off as much chaff as 
possible (this is great for decafs). Then I go outside on the porch to 
finish, or, if there almost no chaff left, place a larger wire colander 
w/the beans over my little powerful house fan.
I like the idea of the hair dryer (blow the chaff away from the house) 
- providing I have an electrical outlet somewhere near the (new) porch.

the stove in my apartment has a fan that blows out over the top of the 
stove,  real good huh??
screw it, I just hold a shrimp frying basket which I dumped my coffee 
into over the fan exhaust and it cools down very quickly.   Sunday's are 
my 'house cleaning' day anyways if I am not working so I just sweep up 
the chaff afterwards... had to sweep anyways and mop so whats a lil more 
in the pan?
Honestly though, with the I roast i use, there isn't much chaff left in 
the coffee anymore anyways, it's not like a snowstorm of brown flakes.

OK, two things.  First off, my partner was reading over my shoulder 
and saw the discussion on BM's.  In our household, with a now 6 year 
old, BM's mean something else.
"Damn, you guys will roast anything - but why are you talking about 
bowel movements?" - I said it was something to do with Captain Cowpie 
on the list :)
As for the hair dryer, I roast anywhere from 12 - 22 oz per batch and 
have used a hair dryer for 4 years now.  It is mounted on a lab ring 
mount, and blows into a large shallow 16" SS bowl, so it is fully 
hands off.  Even with 22 oz, the layer of beans is so thin that air 
blown in the center whisks heat away very quickly and they are cool 
to the touch in a few minutes.

That's good to know! I have a fan set-up, and whilst I love how it blows 
out the chaff, I'm far less crazy about the amount of space it takes up.

Why not a BM? If you want to do larger roasts up to 2#s. If you want to your
roasts to be extremely even without monitoring that each bean is getting
equal access to heat. If you want a stirring motor that is not over
burdened. If you want the ability to hear first and second crack. If you
want to be able to see the color changes. If your cheap. If you are not
afraid of some creative building then a BM roaster might be the answer.  I'm
now over 100 roasts with my BM/TO and couldn't be more satisfied. No
breakdowns or failed roasts.http://coffee-roasting.blogspot.com/

Nice setup!  I have had coffee from two BM/TO setups and I have to say that
it is a very good method of roasting.  I would compare it to my RK setup.
Personally, I would build a BM/TO over any of the commerical offerings out
there if I didn't have an RK setup.  I would guess that you have way less
than $100.00 invested in a machine that will last for a long time and
produce great results.  What do you use to cool your beans?

Les     I dump the beans onto a screen on top of a square fan and suck heat
over the beans for now(cools in less than a min.). I'm working on a
stand/cart to put my setup on. The roaster will be on top with hinges
mounted on front to tip beans out of pot. Then I plan to have my cooler as a
drawer that slides out on drawer slides below my roaster to line up with my
roaster when tipped. I will mount 2 wheels on back like a hand cart to move
unit to store. http://coffee-roasting.blogspot.com/

That sounds like a sweet setup.  I think I am going to start collecting
parts to make a BM/TO.  It will add to my roasting education.  I have
roasted over fire with Adrock, Cast Iron Skillet, Wok,  Poppery 1 and 2,
Wearever Popper, HG/DB, Hottop, Alpenroast, Freshroast, I-Roast, HWP, Z&D,
 Rosto, Dietrich, Probat, and RK Drum.

Maybe I am looking at it wrong but it seems from the pictures that  
you have a really long drive shaft. I'm no engineer, but don't you  
lose torque by having to apply it over such a long rod? That is, it  
takes more energy to drive all that mass. It also seems to me that  
there is some basic physical principle that torque is greater closer  
to the source. A leverage issue, something. It just seems intuitive  
to me.
So my question is, why not alter your BM so that the stirring pan is  
closer to the motor?

Scot     The welbilt BM is in a nice metal housing so it made something
strong and heat resistant to mount my pot on. Also I wanted to keep the
heat  from the hot pot away from the drive gear,belt and motor. The torque
on the shaft is very minimal even when I did a 3# batch, plenty of power and
torque to spare. Ed  http://coffee-roasting.blogspot.com/
