Topic: A Great Big Five-Oh (4 msgs / 158 lines)
1) From: Mark Neuhausen
I celebrated a milestone birthday on the fourth of July.  My cousin, Mimi,
and several people from this list made it unforgettable and fantastic.  Mimi
knew that I had been looking for a Poppery I for some time, and worked with
several people on this list to find a Poppery I (I even saw Alchemist John's
post looking for one and the thought never crossed my mind that it might be
for me), a variac on e-Bay, and all the parts to build a 1500W dimmer.  I am
on a flight home from the Pacific Northwest as I type this, and will spend
the weekend putting my little dimmer ($4 600W dimmer from Home Depot) and
building a 1500W dimmer into a dual outlet box and use my variac as its
input.  And of course, modify the Poppery I to separate the fan and heating
element.  With this set up, I will be able to boost either the fan or heater
beyond 120 VAC, and slow each one independently.  All without the need for a
separate boost transformer (although I do need the separate 1500W dimmer).
I did roast with the unmodified Poppery I a couple times as I could not wait
with the Variac, and without a thermometer, I scorched some beans in the
first batch.  The second batch was very drinkable and has me wanting to not
sleep tonight to get all the modifications done NOW.  Thanks to Alchemist
John for showing me the insides of the Poppery I and it is indeed built like
a tank compared to the Poppery II.  It is easy to see why West Bend went to
a Poppery II as I have to believe that the manufacturing cost of the Poppery
I exceeded the selling price.
I always knew that this list has a great bunch of people on it, and my
birthday memories will stay with me forever.

Mark,
It was great spending the day with you folks.  I can hardly wait to see how 
your WBI mods come out.  Those meil we roasted with the assistance of your 
variac was good but did indeed get a little scorched at the beginning.  The 
gayoland (sp) sumatra OTOH that you left me is very nice.  A good touch of 
earth, funk, smoke and chocolate.  Did you and Mimi get to try the Ugandan 
yet? Have fun with the next 50 years...

Great stuff! I have switched to using my PI almost exclusively. I am 
able to get an easy 200 gr. out of her without rocking. stirring etc. 
I've been meaning to post this for a while, this seems like a good time.
First thing I do is strip her down and throw away the shell, the plastic 
chamber extender, and the metal plate that covers the motor base. Save 
the feet, and the rocker switch from the shell. (I don't use it on this 
machine again, but it works nice to mod a non PI for newbies)
Look straight above the cord where the little metal housing meets the 
plastic. There should be a plug in there. If not block the hole with 
high temp silicone, or etc. If this is left open, it will reduce the 
quantify of beans that can be roasted.
Remove the fan from the heater section, and disable the thermal switch. 
If you don't it will mess with your profiling. After you do this mod, 
make sure you never leave the machine working and unattended.
There are several choices for a chamber. You can use the larger 
hurricane lamp glass and silicone it directly in place. Or, a Fresh 
Roast base fits nicely also in place. The FR base will let use a smaller 
hurricane lamp. If you use a FR base, you must remove the bottom screen 
or else you will significantly reduce the bean load you can roast. The 
FR base and smaller lamp glass seems to improve cooling by 30 seconds to 
a minute; down into the 2 minute range.
I then take 4 or 5 pennies and attach them to one foot. The little lean 
helps bean movement by a fair amount.
My current favorite profile is; 200 gr. of bean, fan boosted to 130 (per 
variac dial). FYI, if you are lucky enough (like I am) to have plugs on 
two different circuits use them. When you cut the heater in, in my 
house, it causes enough voltage drop to slow the bean movement. Anyway, 
I then set the heater to 125 volts, and kick the temp to 300. This takes 
under 2 minutes. I them spend the remaining time between 300 & 6 minutes 
going to 350. This means I normally cut the heater down to about 95 
volts @ around 275. Watch your bean movement, because I normally reduce 
it twice(?) in this time range. I like to keep a nice bubbling action 
going, while not tossing the beans into the air.
When I hit 6 minutes I set the voltage back to 125 and send the bean 
mass to 400. I start to back the voltage off to under 110 when the bean 
mass hits 390. I then spend the remaining time to around 12 minutes 
driving the beans between 400 & 440. In the last 30 second or so I do 
crank the voltage up for a "big" finish. I don't know if that does 
anything for it or not.
To monitor the temp I use a bbq therm that I 've checked in boiling 
water, when I first got it, clipped to the glass with the tip in the 
bean mass just below the level of where the glass meets the metal. Real 
temp, I don't know. Repeatable, yes.
I hope you find this useful. Happy Birthday!

Mark,
I was hoping you and Mimi would have made it a little further south to
Roseburg!  I heard you had some fantasitc salmon at Mike's and a wonderful
time at Alchemist John's.  I would have enjoyed meeting you and seeing Mimi
again.  How is the Thor tamper working that Alex got you?
