Topic: A question for you SCTO guys... (8 msgs / 153 lines)
1) From: Angelo
Have any of you opened your Turbo Ovens? If so, do you remember if there 
was enough clear space in the EXACT center to drill a 1/4" - 1/2" hole 
through the entire unit?
I'm thinking that if there is, it would be feasible to mount the StirChef 
stirring motor on top, thereby eliminating the need for a StirCrazy bottom.
I would also like to know what the RPM's of the StirCrazy are... The 
StirChef motor runs at 10 rpm...
Thanks,
Angelo

This was asked once before- the Stir Crazy arms are directly driven by a 
synchronous clock motor (a gear motor), and I timed the arms at about 15 
rpm. I got curiouser and curiouser, since they usually have the exact speed=
 
printed on them.
Due to the multiple poles in the motor- like an automotive alternator, one=
 
winding and several poles- and the gearbox, it's an odd speed. "15.84rpm"=
 
@60 Hz. And I doubt if there is clearance for a center through-hole in the=
 
TO. Don't have a TO (yet) so only surmise the clearance problem.
There you have it, Angelo. Sorry to be useless on the TO...

I haven't opened my sunpentown, but I don't believe I'll need to for your=
 
answer... There is a fan in the oven which is mounted dead center, so 
drilling through center would completely take out the fan and its motor. If=
 
I'm misunderstanding your question, please ask me again...

Ray,
One out of two is fine with me :-)
However, your answer brings up another question, namely :  Would 10 rpm be 
enough to properly stir the beans?
Anybody?

Hi Angelo,
In my experiments with modifying Turbo Ovens I have opened many of them. 
All the ones I have worked on have a fan the spins around in the center 
of the top. It would not be possible to drill through this fan and go 
straight down into the roasting chamber; but how about mixing at an angle?
With all the talk about drums I have been thinking of making a drum to 
turn in a chamber under the Turbo Oven. However, I really do like the 
bread machine mixing through the bottom of a stainless steel bowl. So 
far it has been roasting wonderful coffee, and I usually roast about 550 
Gr at a time. That's all we need for about a week.
BTW, the strongest turbo oven I have found has been 1465 watts. That 
will do about 2 pounds just fine :)
Hmmm, I run it on a 12 Amp circuit also...
Now I use much less electricity than I did with the air popper. (Same 
electricity, but more coffee per roast, sooo.. one batch instead of many.)
Hope this helps,

Larry,
That answers it, though it's not exactly the one I was hoping for. :-) I 
should have been able to figure that out myself...
Ciao,

Peter,
Thanks... It seems that the way to go would be to use  a pan (I'm thinking 
wok cover) with a hole drilled through the bottom and the StirChef motor 
underneath... just wondering if 10 rpm is fast enough.

Hi Angelo,
If I remember correctly (always some doubt of that lately) when I wrote 
to the Stir Crazy people, their response was that the SC spins at 12 
RPM. I would guess that 10 RPM would do just fine :) Also, I think a wok 
cover would be fine, or even the bottom of the wok, whatever you happen 
to have.
Good luck, and let us know how the results.
