Topic: time to attempt a homemade drum, now hole in WOK (2 msgs / 66 lines)

Gary,
I had the same problem with beans coming out when I attached the severed 
bottom of the bread container to the SS bowl.
The fix was to carefully make a washer that would fit the shaft closely 
and thus seal the hole so the beans can't get through.
The bread machine works well as a stirrer, but 240 RPM is a bit fast. 
Thus the chamber sides need to get vertical quickly.
An 8 qt Walmart mixing bowl seems perfect. They do have larger, heavier 
ones in Costco. Pro quality. Up to 15 Qt I think.
May as well build a commercial machine huh? Stir from the top, Turkey 
frier burner below.. oh my..
Well, I will stick with electricity,  for now...
No beans come out the top, of my setup but they do swirl an inch or so 
below.
To do 2 Kg I need to extend the paddle so it tosses the top 2 inches 
better.
Perhaps even introduce another heater, although I am tempted to try 
using just the GG and tolerate a 22 minute roast time.
 From what has been said on the list as long as the temp keeps rising, 
the beans will be fine no matter the time to roast. Within reason.
The added insulation really helped contain the heat, and with preheating 
the GG I have been experimenting with profiling up to 1 Kg.
You guys almost have me talked into trying 2 KG and reporting back.
Only problem is I would be giving a lot away.. not a bad thing after all.

Still pushing the limits, here in LHC.

Pete, 
I had a thick rubber washer on top of the rotating assy, under the
wok, no problems while it was mounted. I had mounted the locking
mechinism to the bottom of the wok. When you are finished roasting,
you would unlock the wok, and dump the hot roast. The large hole
allow's *lots* of roasted beans to pass thru. It's a major problem,
that eventually forced me to admit to myself that it's not going to
work without an adapter.
Which lead me to a small ss wire mesh drum. That seems to be a great
alternative. And I could not agree more about using a turbo oven, and
recirculating the heat. I roasted 600 grams, with a leaky GGSC system.
I disconnected the heater in the Stir Crazy on day 1. I was never
happy with the Stir Crazy part in the 1st place, after 9 oz's you need
a springform pan, and although it works, is unsteady. And then the 25
cent electric motor is doomed to failure. eventually, all the extra
mass is going to kill the motor eventually.
For under 9 oz, the semi stock ggsc is a good setup. After that, you
are doing a juggling act trying to keep the beans stirring
consistantly.
Back to the drawing board...  :-)
