Topic: OT:Sunbeam C50 vac pot (8 msgs / 224 lines)
1) From: Mark A. Chalkley
I found a Sunbeam Coffeemaster C50 vac pot in extremely good condition
today, plunked 15 bucks down for it, after the guy let me make sure it
works.
Does anybody else here have one of these?  If so, what are the handles
on the sides of the upper bowl for?  They appear to compress the seal
to make it expand outward and make better contact with the lower bowl,
but if you press them all the way down, they seem to force the two
bowls apart - I'm not sure what that's all about.
Also, how is the north time determined?  Is there an internal timer or
what?
Any other tips?  Did I waste my money?
Thanks for any help!

Trial and error or try what others have found that works, try three 
minutes at first and adjust.

Only one tip from me  - a C30A user.  Don't wait for the machine to kick 
down on it's own.  They take WAY too long.  Once all the water is up 
north, switch it to 'low' after no more than 90 seconds if you have a 
nice fine grind.  I'd experiment.  I've 'tweaked' mine for a 30 second 
time after the water has gone up before it flicks to low.   As-is, 
you'll get some pretty nasty coffee.
Oh yeah, don't ask me how to modify the thermostat in a C50.  I have no 
clue!

Mark,
I have a C30 and a C50, and both make very good coffee. I agree with a brew
time of 30 seconds, I like 25, which will yield a up north dwell time of
under 3 minutes. This time is in line with Tom's preferred time for press
coffee of 2 minutes when using fine ground coffee.
A search of HR Digest will bring instructions for dialing in the right brew
time.
I suggest you just pull the plug at 25 seconds, time the whole time up top,
and see if you like the coffee.

Having returned from my excursion to Maine, I thought I'd try out the
C50 I found at an antique store, first just using plain water to see
what happened. It was interesting enough to report, and a bit
different from what I expected, based on the info I've gotten from my
inquiry here and my web ramblings.  For those interested, I'll
summarize the test. I'd like your comments.  Is it possible my unit
has already been "adjusted", or maybe Sunbeam made some later models
that work better than earlier ones?
I put in 6 cups of cold water, set the switch to "Brew", and plugged
in the cord.  Nothing happened, other than typical heating noises, for
exactly 5:00, when water started appearing in the upper bowl.
All the water was up by 5:20, and there was violent bubbling. I mean,
as in "Do I throw the whole thing out the window, or just run?"
bubbling. In the end, I did neither and just watched from a respectful
distance.  I did get close enough to throw a digital thermometer into
the bubbling water - it read 208F.  By 6:30 the bubbling had ceased,
then nothing until 7:40, when I got more violent bubbling until 8:10,
then nothing until 8:40, when there was a rapid, and I mean _rapid_,
suck down.  Within 5 seconds, all the water was down.  I realize suck
down will be slower with coffee in it, but I'm not too sure how much
slower, given the suddenness of it.  The amount of bubbling I could
hear in the bottom also indicated that quite a bit of "vacuum" had
been built up.
So, the upshot is:  Without coffee, I had a total north time of 3:40,
technically a little less, since that's timing from the beginning of
water appearing in the upper bowl - 3:20 if you count from when all
the water was up.  That's not bad, in my book, since I usually have
times very close to this, usually closer to 3:50 - 4:00 (when brewing
5 cups), with my Hario.  Again, I know it'll go up some with coffee in
it, but does it sound to you folks like the typical Sunbeam profile?
(I didn't touch the control or pull the plug in the whole test.)  It
sure doesn't sound like it to me...
I suppose I'll have to go make some coffee in the thing.  But I'll
have to roast some first...

You will likely find that this time is way too long.  I've tweaked my 
C30 to have a 'heater on full' time of about 30 to 45 seconds after all 
the water goes up north.  This gives a TOTAL time of about 3 minutes 
before the last of the water is sucked back down.  It goes down alot 
slower with coffee in the top.  Stock, the Coffeemasters make lousy 
coffee.  They just brew way too long.

Hmmm, well I'll give it a try with some coffee in it and see how much
the north time increases.
Meanwhile, I guess I'd better plan on taking the thing apart to see
what makes it tick...
Thanks!

Mark, I know the C30 'tweak' procedure, it's pretty easy.  The C50 is an 
unknown.  The C30 has a bimetallic switch that flips the temp lever from 
high to low when it hits the 'right' temp.  A little fidding with a 
small wrench and screwdriver (and a lot of patience) got it adjusted. 
 The C50 may or may not be similar.  Just make sure to let the pot cool 
all the way (fill with cold water) between adjustments.  If you keep 
re-running the test without cooling, you'll get skewed adjustments.
