Topic: Woohoo! (19 msgs / 368 lines)
1) From: Russell Green
My frankenroaster works! As I've posted a few times, I cobbled  
together a Ronco rotisserie and a drum from a guy on ebay. Took a  
suggestion from another post and added another heat source to speed  
up the roast to 15-18 minutes. Can do a pound of greens in that time.
We had a cheapo but almost new Sunbeam toaster oven in the garage  
that had dropped off the shelf a few times. Voila! My extra heat  
source! I gutted that puppy for its two heating tubes along with the  
timer and heat control. Then I laid them on the bottom of the  
rotisserie on top of the toaster oven's tube heat shields, got some  
extra hi-temp wires, spliced them in, and laid the toaster's heat  
control/timer panel on the backside of the rotisserie. 800 watts of  
roaster boost. Now if I don't ground the heating element terminals on  
the metal liner of the rotisserie . . . Anybody have suggestions for  
a thermal insulator for those terminal posts?
So far I've been able to get 10 oz of Sulawesi to a deep French in  
about 18 minutes and another 10 oz of Lintong to FC+/Vienna in about  
16. Gotta watch it, though--this thing's hot! And my fan to cool the  
beans is absolutely necessary.

Hi Russel,  Congratulations....
  How about some potter's clay and shape what you want and fire them and 
have ceramic terminal posts, feet, connectors or whatever.  I'm no 
expert but some clays ate pretty low fired.  Probably someone else here 
  nows more about potter stuff.

Great job! Sounds like you're getting right in a drum roast time sweet spot.
Now what I'd do is have all heater sources hard wired on full tilt and
control them with a voltage boost capable variac. 
Here's a URL for where I just ordered some 1" thick 2300F ceramic blanket
insulation material to insulate my Bricoletta boiler. FWIW could also work
quite well for insulating a roaster. They have all kinds of heat related
stuff including terminals etc. so you can likely find what you need.http://www.infraredheaters.com/index.htmlKona Konnaisseur miKe mcKoffee

Mike,   That looks like a good resource.
I suppose you would use some sort of wire mesh to support the blanket in 
a roaster? Is it pretty saggy? An adhesive would be nice. Is there a 
suitable adhesive?

What I found was that the low fire clays could not handle the extreme 
changes in temperature and cracked within a few roasts.  Porcelain 
should work, but it is not low fire.
Something I do think might work is some silicate stiffened kaowool 
painted with ITC-100 (with is a porcelain covering).  Those materials 
are all used for furnace work and should work nice.  The main trick 
is they are not really cheap.

To Russell,
I think any handyman shop would have ceramic standoffs that would work or 
could be adapted.  Find an old toaster oven at a thrift store and salvage 
the standoffs from that.  A good hardware store might have some too.
It's insane to think you'd have to make them and fire them in a kiln.

Damn!!  I really am Insane.... I liked that idea.... I would do that and 
be insane and not realize it.

Russell,
I agree with ED.  I just made my daily (at least once) pilgremage to
the local True Value hardware store.  I check on insulator and high
temp standoffs - they had several types.
Mike (just plain)

I do want to mention..... I did not buy any clay.

insane, right here, thank you very much :-)  I just have this damn 
DIY streak.  Moding just rubs me the wrong way.
We will work on a set together Rob :-)

OK...Insanity is very subjective.
I take it back.
rephrase:
"I think there is a much easier, but not so creative way to add porcelain 
standoffs to your project."

14) From:
I used a castable refractory called Greencast 97, from the AP Green Co in
Mexico, MO. They had a distributor in Denver that was handy from Mines in
Golden.
Expensive stuff, it would withstand the 2000 degree F environment of our
test jigs. They had other products of lower cost, but just do a
Googlesearch for castable refractories or try to find a source of
Fireplace
Mortar. The hardware store or contractor's supply house should have
reasonable products on the shelf.
There's a high-temperature electrical insulating tape that looks exactly
like medical bandage tape. Again, the hardware store should have it. I got
mine from Johnstone Supply.
Happy modding in the new year!
Cheers -RayO, aka Opa!

You are the first person that I have come across that has actually 
used some.  So, how durable or conversely, fragile is it.  I tried at 
one point casting with just a gypsum plaster and it became very brittle.

Several years ago, my wife gave up caffeine. I don't remember why, but =

hope, I hope, I hope.
Woohoo!

Oh, this is funny - Spellcheck is set to automatically run when I hit =

She may find it is not the caffeine that was bothering here but rather
chemical additives that are added to commercial coffees and are absent in
organically grown home roast

I also find that I don't react to coffee when its espresso.  With other
coffee methods I have been known to take a few aspirin a half hour before I
drink the coffee.  Any thing with robusta is going to kill my head.  The
very worst for head pain is Boyd's coffee.
