Topic: 1oz-28g HotTop Batch (3 msgs / 79 lines)
1) From: Jeffrey Pawlan
Mike and Michael,
  Another option with the bean probe which you might want to experiment with, is
to open the hottop and bring out more thermocouple length into the drum. Then
bend the thermocouple very roughly 90 degrees in the kevlar insulated portion
just beyond the bare junction end. The goal is to make the bare tc end
horizontal within the bean mass and bring it down as far as you can without it
touching the drum stirring vanes. By bending in the insulated portion you don't
risk affecting the uninsulated wires which might make a double junction or even
crack if you bend the welded end. By having the junction portion horizontal,
you can get it in a smaller height of beans in the bottom of the drum.
  Previously, no one wanted to run less than 165g so that is why I did not
suggest it before.
Regards,
Jeffrey Pawlan

Jeffrey, thanks for the suggestion.  I may try that this weekend.  I've got 
a pound of the Liberia and I'd like to get more than two trys at it.  I'll 
experiment first with some older stuff that needs to be used up anyway.

My best guess bending the bean temp probe slightly downward may work down to
maybe 1/4#. Won't work for actual bean temp with wee 1 to 2oz sample batch
sizes, bean layer too thinly spread out in drum, like one bean think! And
the probe needs to be slightly about the stirring vanes in the same area of
the drum as the probe. No biggy, getting very repeatable consistent small
sample roasts.
Oh, FWIW successfully worked out much higher 325f bean temp probe charge
temp. Use first stage target 275f, bean probe drops to ~250f after charge.
Stage 1 drying set 1:30 to 285f, stage 2 drying 310f 2:00 (310f free air
bean temp probe not actual bean temp, remember bean ~12f lower)... Now very
little time from end previous sample batch cooling to next batch ready
stablized 310f chamber probe 325f bean probe temp for drop. 
Just in case anyone else decides to use a CCR HT for sample roasting not
just profile roasting:-)
