Is it hard to hear the cracks when roasting small batches (1/2 lb) in the RK
Drum?

John,
is the RK your only roaster? it can be hard with small batches. I have trouble at times with large batches at the Phoenix Public Market. Too much outside noise and too much talking with people while roasting.

I do 1/4 lb roasts and it depends on the bean. Most beans I can hear 
first crack well. With some that are spotty like Sulawesi or Yemen there 
may not be many. With peaberries I may not hear any. Second crack can 
always be heard well.
They can be heard just as well as larger batches, it's just that there 
won't be as many. 1/2 lb is still a pretty decent size. 1/4 pound is 
pushing the lower limit.

I stop my motor for a second or two when I know it's about time - then
I fire it right back up - this "sound check" plus my thermometer and
clock are all I need....

the quiet when the drum stops is great, because any sound from the
beans will confirm or deny I am at the right point in the roast...

I'm all ears and taking notes on this one, although I just know I am going
to burn the devil out of myself, trying to unhook the drum, open the door
and discharge all the beans into my cooler.
Even with my leather welding gloves, I know I'll need a quart of Aloe Vera
Gel to salve the burn spots. Anybody seen a Fire Suit on eBay?
I still have my doubts- maybe I can cool the roast in situ by ducting the
full blower to the drum after I kill the flames. Another hurdle to bridge.
I sure can't handle a hot drum fast enough to dump the beans into my
colander in the blower's inlet venturi.
Two seconds to halt roast becomes a five to ten second stop with the added
drum mass and 2 - 4X roast mass. The blower has a teriffic output blast,
compared to partially blocking one of the two inlets with a colander loaded
with beans.
I guess I won't know until I try it.

My problem with the drum is the squeaking from the outboard end of the
spit as it turns in the metal fork...  Someday I will find some
heat-resistant bearings or rollers that can quietly support the
outboard end of the spit - then the neighborhood won't think I am
raising mice....
Until then, I just turn it off for a few seconds to hear the status...

AND my drum is home-made, not RK, so this may not apply to Ron's
standard setup....

Ginny, I don't have an RK, I'm trying to figure out what my next roaster
will be.  I have to do decaf and caf; so a 1/2lb batch will be common for
me.  I like the drum very much, but am also interested in methods that
provide more airflow around the bean than a BBQ drum e.g., BM based
roasters.
And thanks to others that posted:
David E., It's encouraging that you can heat the cracks as well as you can
with larger batches.  That answers that question, thanks.
JeffO, your experience is what I was expecting; that there are times that I
would be unsure of the crack timing.  I wish there was some way to get bean
mass temperature from the drum as a supplement to my less then stellar
hearing.
Brett, your suggestion of a quiet end bearing, and stopping the motor is a
reasonable approach for those times of uncertainty. Thanks.
John

Lubricating oil...

15) From: Brett Mason
tried that - the heat makes it into an acrid white smoke.  Am I using
the wrong stuff?  Suggestions?
Be nice,

Get it slippery with some high temperature grease or silicon and keep it out
of your beans when you dump.

I added some bearings to mine and it did help.

Brett,
I wrapped some teflon tape on the fork area where my spit rides and it stopped squeaking.  When the tape wears, just replace.

I'll try the teflon tape next.  If I need to go further, I'll head for
the hi-temp grease!
Thanks all,

ACE hardware, or equivalent.  Bearings of all sizes.  I got a 1/2 inch steel 
rod and corresponding bearings from them for my RK set up.  The bearings 
were quiet for about 1.5 years of roasting, when they started to squeak, a 
drop of oil quieted them down.  The outer race of the bearing sits on top of 
the rotisserie support brackets, the inner race rotates with the rod.  I 
ground out a semi-circle shape on the tops of the support brackets so the 
bearing has a place to 'sit'.  The drum needs no support to attach it to the 
rod as the rod was very tight going through the RKs inner 1/2 inch square 
tubing, tight enough that the drum rotates with the rod.
Respectfully,
Rich Adams

i wonder if you could use a stethoscope to hear the cracks.  probably catch
all the other random noise too though.  but if you ran it through an
audio filter, FBI style, looking for the right frequencies...there's an
opportunity for addon sales - magnetic stick-on coffee crack amplifier for
grills!

How about a slice of teflon coated breadpan or a piece of stove top pan =

to support the spit. A slick heatproof surface without the need of other =
lubricants.

Squeaking can be stopped easyly with a couple of drops of slick 50 oil 
additive or any lithium grease. I use the slick 50 and as it is on the 
outside of the grill there is no need to worry about it getting inside with 
the coffee.

Good idea, I like those cheap ideas.  I looked for bearings and the only =

Two bronze bushings (one inside the other) and two shaft collars and it 
works like a charm.
I sized the first bushing to just slip over the spit rod.  The other would 
slip just over the first bushing.  The shaft collars hold them in place, one 
on each side.
I don't have a picture of it, but I got all the parts at Ace Hardware for a 
few bucks.
