Topic: Adding a thermometer to IRoast2? (8 msgs / 329 lines)
1) From: Scott Morford
I'm wondering if anyone has been successful in adding a thermometer to
the IRoast2. I'm getting to the point where I'd really like to plot
out my roast curves, but the onboard sensor with the unit is just not
cutting it.
I was looking at the digital thermometer with the wire probe, but I'm
worried that the wire might melt if snaked through the chaff
collector. A stem themometer seems like good option as well, but
requires drilling holes in the unit. I don't want to introduce my
roaster to the drill press if I don't have to!
I'd like to hear about what's worked and what hasn't when trying to
mod out your IR2 with a thermometer.  Thanks ya'll!
Scott.

Hi, Scott.  I use the wire probe, put it through the top of the 
chamber, it does wear on the wire, so I use a different spot every 
few times.  I get the wire in the middle of the stash and off I 
go.  It works great.   I found that with a air duct attached to the 
top, going to my ceiling exhaust fan my IR2 runs almost perfectly to 
the temperature it claims.   Now outside it depends on the ambient 
temperature and the humidity.  I let the top float as was recommended 
to me, but I make sure the escaping chaff doesn't make its way to the 
back intake area on the bottom of the IR2.
Someone suggested taking off the screens on the top, that is my next 
move.  I just need to find time to do it.  It will blow out the 
little chaff and really let the heat escape.
So, try the wire thermometer, it works for me, though I don't use it 
every time.  Once I have a profile down, checked it a few times, it 
works great.  Now, if I accidently leave the fan off, but have the 
duct work on the machine, it is just a place for the heat to gather 
and the thermometer goes way up.
However, if all is working I am  almost always right on, maybe  off 
by a couple of degrees, which can make a difference, so I adjust 
things, but it does work.

Scott,
keep us all posted. I have not started on that project yet myself. I studied
the unit and have been thinking about snaking the probe up through the
bottom chamber. I was first going to see how much space is in the bottom
chamber by removing the plastic cover plate on the bottom of the unit. If it
looks good I was going to attempt to drill a hole in the main body and mount
the read out with Velcro to the side. The plan that is in my head ( maybe
someone already beat me to it) was to bring the probe up from the bottom
chamber and make a feed hole in the roast chamber so that when you lock the
bean/roasting chamber the the body of the unit the tip of the probe goes
through the hole made and becomes buried in beans as they are roasting.
In my head this works great. Now I have to experiment. I would drill no
holes till I was sure as can be that this would work. As it stands I don't
even have the thermometer purchased from Tom yet.

On the flip side I may wait till I have another counter top roaster so I
don't shoot myself in the foot and have no way to roast my greens.

Save Wampum.
A bread machine from a thrift store should be plentiful after January,
but look now. The price should be under $10.
In the Dough cycle, the metal paddle will just spin, as in kneading a
ball of bread or bagel or Cinnamon Roll dough. If you happen to put
250g - 500g of coffee beans in it, your $35 - $100 heat gun could be
aimed into the pan while the beans are agitating. Stop and cool at any
time.
Got a Bread Machine you don't use? Egad- the bread you're missing!
Cheers, Mabuhay -RayO, aka Opa!
Roasting = Heat + Beans. It happens
