Topic: ok..... bear with me, i'm new, and need hottop help.... (4 msgs / 140 lines)
1) From: Randy Allen
and in learning how to roast, i've plowed up my first snake,
as the saying goes..... here is my problem....
brand new hottop, and for the first roast, i threw in the beans
that came in the box. as a practice run, so to speak.
worked perfectly. unit worked fine, coffee came out with a nice
full city roast, near as i can tell.....  good for practice.
i clean the unit out of chaff, and cause i am new, and curious,
i remove the drum to see how much crap is left in the nooks and
crannies... clean it out, and reassemble. i take pains to set the
locating pins correctly on the end plate, and tighten the screws
gently... two finger snug. put the glass end cap on, and start my
first real roast, a classic expresso blend on full city.
adjusting the gold tension knob for silent running, i dump in the
beans at the beep, and start the timer. 2 minutes into the roast,
the drum starts scraping on the lower portion of the support plate,
and after a couple turns, jams.
i unplug it, wait for it to cool, dump out the beans, take off the drum
support plate and see scraping from the drum on the support plate.
figured i just didn't have the tension on the end knob high enough to
keep the drum pushed back in the roasting chamber, and it's walking
forward into the plate. i give the plate a little tweak with my thumbs,
put it all back together, adjust the tension on the screw to apply pressure
to the drum, and run it dry to see if it works.
works perfectly empty. i stop it after 12 minutes, let it cool, and start to
do a real roast. it works perfectly, i'm right in the middle of second crack,
push the button to dump the beans, the gate opens, an ounce of beans
comes out, and the drum jams again.
it won't dump beans cause the drum is stalled, so i unplug it, and wait
for the residual heat to burn the crap out of the beans left inside, which
it does nicely.
after the smoldering and horrible stench subsides, i clean everything out
again, fiddle with the support plate, and test it.... it runs perfectly, 
with no beans.
i fire it up again, and try it again, and this time it produces a nice 
batch of beans.
however, it begins scraping right at the end of the roast, like it was 
gonna jam again.
what am i doing wrong here? anybody who has experience with a hottop, and
can shed some light on this, i'd be really grateful....

Randy,
I had a similar problem when I first received my Hot Top. I would get
a lot of squeaking when I was warming up. It seems that the drum can
get knocked out of alignment during shipping.
Try taking the front cover off and put your finger into the bean
shoot. Then rotate the drum while holding your finger against the top
of the drum. You should be able to tell if the drum is out of
alignment. You should not feel any high or low spots during the
rotation.
I was able to bend the drum slightly to get it back alignment.

Hi Randy,
Since the Hottop drum is supported at only one end, it's vulnerable 
to distortion in shipping. Here's what to do about it:
With the unit cold, remove the front cover and the load chute cover. 
Leave everything else in place.
Put one hand into the load chute so that your finger runs on the 
inside of the back edge of the drum. By design, the drum runs even 
with the front edge of the load chute. While slowly turning the drum 
with your other hand, check this and watch the gap between the front 
edge of the drum and the front bearing plate. When you see the gap 
get small on the bottom, you'll likely also find the back edge of the 
drum running low at that spot. Carefully, while supporting the front 
edge of the drum, pull the back edge up a little. Keep doing this 
until the drum runs evenly all the way around. This shouldn't have to 
be repeated unless the unit is shipped or dropped.
It's also worth while taking the front bearing plate and verifying 
that it's flat, except for the bearing tongue itself, which should be 
pushed back a couple of millimeters or so. While it's apart, put a 
little grease on it. You want a thick, high-temperature, food-grade 
grease. So far, the best I've found is a silicone grease from 
Refrigeration Technologies, at 
. You should probably 
also be aware of Randy Glass' Hottop FAQ, at 
. Hope this helps.
Best,
	David

Or, you can simply eyeball it: Pull the drum and hold it with the free 
end of the shaft up. Sight down the shaft and note how the shaft is off 
center. Gently push or pull on the shaft to center it, using as little 
force as possible. Repeat until the shaft is centered and reinstall 
drum.
