Topic: iroast lid mod (45 lines)
1) From: Kevin Creason
I'm trying a lid mod on the iRoast2.
I left the screen-lid off and held down the chaff collector with a piece 
of 14ga galvanised wire from Waly's world (purchased to finish tying off 
the new crepe myrtle in case Dean comes this way-- which he probably 
isn't). Very simple, very easy to do, and I don't think it will cause 
any permanent damage. I took a pictures in case anyone is interested: http://texascreasons.homedns.org/gallery2/main.php?g2_itemIdF24The air definitely moves much better than with the lid on. But it still 
roasts too soon, so I think I still need to lower the programmed temps.
I ran 1 cup of Kenya peaberry (6.0 oz-- I cause I need to switch the 
scale over to grams, I'm just not used to thinking in those terms) with 
Tom's recommended settings for the iRoast to City/City+. Tom's note says 
"(a bit lighter than probably most folks like their coffee)". Ha! I cut 
it short cause it would still have gone too dark if I let it continue. 
The settings are 350/2:00, 400/3:00, 460/4:30, a total of 9:30. Times 
below are time remaining from the display countdown, the first temp is 
the OB thermo reading, second is off the bottom glass read with an 
infrared non-contact thermo, last is the exposed top indentation in the 
chaff collector same reading method.
-8:00, 282, 146, 126
-6:30, 320, 198, 142-- dark yellow, blowing slowed down so the temp will 
build for next stage
-5:30, 342, 237, 154-- brown quickening, a few cracks
-4:55, 350, 250, 160-- quickening crack, not rolling yet but almost
-4:00, 352, 286, 160-- still cracking
-3:30, 370, 300, 165-- blower slows down again to build temp for next stage
-2:45, -- -- next crack starts so pop it into cool down no temp reading 
once in cool down (that's unfortunate!)
It looks very nice-- the little peaberries were tumbling and moving very 
nicely because of the extra air flow. Some chaff particles escape so 
this is probably not an in-kitchen modification.  But I still had to cut 
it short by two and half minutes. I am so leery of programming anything 
over 400 now! I think it needs to finish with the 400 temp and be like a 
380 in the middle.
