Topic: Actual weights of coffee..... (3 msgs / 62 lines)
1) From: Robert Holland
Hey Tod, I don't know what kind of weights you got with your "jewelry"
scale, but being a jeweler for many moons, jewelry weights are in TROY
oz. There are 31 grams to a troy oz vs. 28 grams to a avoirdupois oz.
Probably does not explain your total weight problem....

heheh, this little toy is more of a toy than you think.  My weights are in
grams, and the largest weight is 20g.  I have 100g total in weights.  I use
the 20g and the 5g weight, and weigh out 3 measurements of coffee in the
tiny tray (for a total of 75g).  It's a bit tedious, but the
mad-alchemist-in-the-lab factor was too much to resist, what with my giant
gray Variac and voltmeter in the background etc. ... picture Gene Wilder
saying "Elevate me..." (Young Frankenstein).
I think my main problem is/was lack of "empirical observation"; my initial
statement that I'm 20g off was probably a bit inflammatory, especially since
I wasn't really keeping an accurate record of how much I'd already taken out
of the bags, other than knowing how many batches I'd roasted.  I'm glad I
asked though, since someone replied that they have indeed weighed the
incoming coffee with a large enough, and accurate scale.
When I get a digital scale (I plan to order one after Christmas), I'll be
able to subdivide a bag into more even batches.  Main goal is to have the
same size every time, to perfect the roasting profile (whatever is possible
with my over-loaded setup), and hopefully to also avoid that odd-sized "last
batch".

Ok, now I need to start looking for a counter balance scale again, for 
appearances if nothing else .
