Topic: Gene Cafe- Emergency Christmas Surgery (10 msgs / 190 lines)
1) From: Jeremy DeFranco
It was a couple days before Christmas, and the Gene Cafe had been cranking
out coffee like a gem. Just the day before, I had knocked out about 5 pounds
or so, and this day my goal was another 5 pounds. All this coffee would be
for gifts. I planned to roast four pounds the next day for me and relatives
to sip on for Christmas week. I was knocking it out, using Eddie's new
profile, and my new bean cooler, which reduced cooling time down to 20
seconds. I had just dumped a batch into the bean cooler, and set the
roasting canister back in the roaster for it to go through the cooling
cycle. Within an instant I realized just how much I had taken the Gene Cafe
for granted. As I was stirring the fresh roasted beans in the bean cooler, I
heard the sound of the GC cooling cycle oddly dissappear. I turned to look,
and the machine had shut itself down without fully completing the cycle. I
quickly noticed that I hadn't locked the roasting canister completely in
place, and the drum had stopped turning because of it. I hoped I didn't burn
out the motor! I turned the machine back on to complete the cooling, and the
fan kicked in, but the drum didn't turn! That's odd. I let the machine cool
down, and hoped it would all work itself out by the time the cooling cycle
had ended. After cool down, I hit the start button to see if it worked. Well
the motor kicked in, but again, the drum didn't turn! Another thing that
wasn't right was that I could all the sudden turn the drum manually with my
hand. Normally, it won't spin like this, but will remain locked in place. At
this point, my mind was racing- I had atleast another 2 1/2 pounds to roast
today for gifts, 4 pounds to roast for myself and relatives the next day,
and 10 pounds to roast later in the week for other family members- how would
I get this done?! Without hesitating I broke out my iroast2s, and began
roasting 1 batch at a time. Now this was a hassel to roast just 3/4 of a
pound, and I had over 15 pounds to go! At this point I knew what I had to
do- I had to open up the Gene. It needed emergency surgery! I looked in the
instruction manual and on the roaster for any sticker that would say the
warranty is void if opened. No such sticker, it was time to go in. I took
out all the screws, and began to lift off the hood. It took me about 30
minutes to figure out how to take the damn thing off without breaking
anything. Turned out to be real easy- can do it now in a few seconds. Well,
I got the top off, and hit the start button to see what was going on. The
motor started (good), and again, the drum didn't turn. I followed the axle
to the gear that was supposed to turn the drum, and AHAH! It had simply
slipped out of gear! I tooked a pair of pliers, and shoved the gear back in
place. With machine still apart, I hit start, and this time the wheel
engaged- It worked!! After taking about 45 minutes to figure out how to
close the unit, I got it back together, and set out to commence my roasting
session. Man, that was close! Glad to get back roasting with the Gene! I
loaded up some Java Djampit, and went to set the drum in place.... What
the..??? All the sudden, it was hard to slide the drum into proper position.
It all-the-sudden required force, where before, it would easily slip into
place. That's odd. I figured maybe it was just from recoil after opening up
the machine, making everything tighter. I hit start to see how things went.
I noticed that the machine started to make a noise everytime the drum went
around. Almost like there was excess pressure on the ends of the drum. I
figured maybe the drum needed to be broken in again each time after opening.
I remember a similar noise when I first got the machine, but it had long
since passed after use. Well, after 2 roasts, the noise was still the same
intensity, and I decided to stop the roast day for fear of causing damage. I
closed up shop, and opened up the Gene for one more surgery. After about an
hour of dumbfoundedness, I finally realized that the problem was simply that
I had not properly aligned the two slots that hold each side of the drum.
They were off center! I had put the gear back in place, but not in the
proper way- where the two slots were centered with each other. So this time,
I made sure they were aligned before slipping the gear back in place (I put
the gear in place with the drum in locked in proper position). Now I was
ready to go! Sure enough, after closing up, the canister slid effortlessly
into its slots, maybe even easier than when I first got it! Over 25 roasts
later I haven't looked back. The Gene Cafe keeps perfoming roast after
roast! I have more appreciation for the GC now than ever. What a great
machine.

glad to hear you got it working again. what a great time for a miracle! 
wish i could say the same. my SC's motor and metal stirring shaft have 
been giving me more and more problems, tried replacing them a few times 
but nothing seemed to work. had to pull out the popcorn pumper to do a 
few emergency batches for christmas @ grandma's (using a variation of 
eddie's GC profile, sans thermostat, got some nice C+/FCish melanges 
(got spoiled not using an air popper, forgot how uneven these could 
be)). i've scrapped the SC portion of the SC/CO in favor of a stronger 
motor/deeper roast chamber. more on this when it's up and working...

Well done Jeremy,  I am glad the unit is so well built.  It also makes me
appriciate the simplicity of my RK drum and the fact that I was able to do
all of my Christmas roasting in  4 - 3 pound batches.

Jeremy,
When you have time, would you write up a description of idiosyncrasies with
removing and reinstalling the top?

Hey Jeremy,
 
Care to share the steps to opening up the Gene in case (God forbid) any of
us ever need to do it.
 
Thanks and Happy New Year!
 
Gil

No problem, Eddie. I'll try to get to it as soon as possible. I will be back
to a busy schedule again, though, starting Tuesday, so can't promise how
soon I'll get to it. Cheers!
