I've been reading this list for a while but this is my first post. Finally, something I can contribute! I bought a second bread machine this week as a backup - hate to think of being without a functioning bread machine now that I'm hooked on roasting. I had the exact same experience with shutdown after 4:30. Since this was a backup machine and I'd only paid $3.50 for it, I figured I'd risk opening it up. It was super easy to see the thermocouple wires attached to the side and I removed them and just tucked them back away from the roasting chamber. I also did some other stuff in there, but will save those details for another post if you're interested. Since I wanted to make sure I hadn't screwed anything up, I tested the machine before trying to roast again. Guess what - it still shut down after 4:30! So I just left it alone and it came back on after another 5 minutes. Since I've never actually used a bread machine for anything dough related, I never imagined
there would be a resting period in the dough cycle. I learned that if I turn it on, set a timer for 10 minutes, the machine would start back up and run for 20 minutes. That's more than enough time for my 1 lb roasts. I don't know if the thermocouple was actually ever a problem or not, but I roasted a nice batch after I got the thing put back together. My other bread machine has only shut down on me when I tried roasting less than a pound and I have not done any modifications on that one.
You've probably seen this before, but here is what the thermocouples looked like: http://www.geocities.com/krisbhatti/images/IMG_1017.JPG
For any future bread machines that I get, I will definitely test the dough cycle first thing without heat and beans to find out that machine's agenda. Oh yes, there will be more machines...

Subject: +First Try with a bread machine
Well, I figured I would go whole hog and try a 1 pound roast in my old
bread machine with my heat gun without any testing at all. Gotta live
dangerously. I knew I was pretty well covered as I normally roast with a
heat gun/dog bowl and had that standing by in case there was a problem.
I was roasting Ethiopian Organic Dry Process Sidamo. (I love this bean!)
Into the bread pan it goes, select the dough cycle and press start. Turn
on the heat gun and away we go. At first it was a pulse type cycle and I
noticed that the count down timer said 1 hour and 3 minutes.
Everything was going very smoothly at the 3 minute mark as the machine
switched to a constant spin from the pulse. Chaff really started to fly
at the 4 minute mark, a little slower than my 1/2 pound roasts in the
dog bowl but still fine.
Then a potential disaster at the 4:30 mark. The bread machine just shut
off. The display was still lit but no motion from the paddle. When I
clicked stop and then start again the display said "HI" so I knew that
it had overheated. The disaster was averted as I quickly dumped the
beans into the dog bowl and continued the roast. I will find out
tomorrow how the roast came out. I pulled it at the 14:30 mark which was
about 45 seconds after first crack finished and it looks and smells
normal so I don't think the small delay (about 15 seconds) hurt anything.
I will be dismantling the bread machine in the next couple of weeks and
removing the thermostat that I expect is attached to the side of the
baking (roasting) chamber.
I gotta say thanks to Kris for talking about her Bread Machine roasting
at the PNWG V and answering my questions about it. It inspired me to
give it a try. And yes, I am starting a search for a moka pot. There is
an Italian grocer/deli/bakery nearby that has a large selection. I never
looked at them in earnest before but will the next time I am there.
