Topic: New list cops? (9 msgs / 146 lines)
1) From: Wandering Curmudgeon
Hey we've got newbie list cops.    Are there some new CSA rules to go 
along with all this? 
Mike, move me from 80% to 90%   We may hold a family retreat somewhere 
in the Portland area.  Everyone seems to like the week following for the 
wild shopping and beach testing.    Are your dates locked down?
Anything happening coffee wise in the Lone Star State?   Did the Houston 
meet ever come off?   Want to try another one?
Anyone working on a wild and strange roaster?  anyone want to buy my old 
mini-atx coffee roaster?  Anyone know how to start a GE Jet engine? ;O)
John - Life is great in the slow lane  -- I'm going to go park and point 
Carolyn's hair dryer out the window and see if I can slow down traffic 
on the FM road behind us ;O)

As a matter of fact YES I do, I worked them for 15 years.  I can start 
it, fix it, rebuild it, anything you want.   Though you probably want an 
allison if you are looking for the ultimate hot air roaster.

I did some of that also (many moons ago). However that should be an 
Allison turbo prop. You can use the prop for both stirring and then 
cooling!!

Sounds like the ultimate blade grinder!  You should get a job with one
of the big-can coffee companies: green coffee in one end, obliterated
coffee chucks out the other.
Is their a mil-spec for bean strike tolerance like with geese?

Aaron,
I'm partial to the GE engine.  I blew one up on the test stand at Boron 
while working on the autostart for the YC14.  I was the programmer and 
only followed the flow chart that I was given.   I still have a small 
piece of both N1 and N2 in my hobby locker.  But I can tell you that 
little engine would have done the job on my cement truck roaster!    My 
biggest problem is how to cool 400# of coffee quickly :o)

Hey now!  What's the EGT on a turbo?    I could reverse the prop and use 
it to cool ...    Anyone want to buy a GE jet engine?

EGT  or T5.4  can hit very high temps.  1500 Deg F is in the operating range.  Once it hits the exhaust  now id say oh maybe 700 to 800 degrees because its mixing with fresh air again.  I never blew one up but I did send a fireball out the stack about 50 feet into the air with one =:O
As I said earlier, run it lower rpm's  or do what is called 'motoring' the turbine.  You use the starter to turn it roughly at speeds up to 2000 rpm or so but don't add fuel.  Get a lot of air throughput to cool things down.
We cook the beans, then kill the fuel and let the thing motor to cool the beans down after the roast.  Then turn your cement mixer in the other direction and bring the beans out.  
I think we are onto something here.  A little tinkering and I bet we can use the cement mixer to actually make coffee too,  a heat exchanger use the waste heat from the turbine to boil water, when the water gets hot nuff, pour in cement mixer with ground beans from going through the turbine,  then when it comes time to serve, just run it through a few stretched out bedsheets to filter the grounds out of it (clean bedsheets now) and we got coffee for a crowd and a half!!    We must might have to present this to the get together gathering that some folks are planning on this list.....

Hey, that's my old 5 speed Schwinn Fastback Sting Ray!  Can't figure out why 
they thought the stick shift might be a bit of a safety hazard .
