Topic: Thoughts on my next roaster. TO on last legs? (54 lines)
1) From: peterz
Hi Matt,
I have been roasting with a Turbo Oven for a few years now, and it has 
been on it's last legs more than once.
First time I took it apart and found the thermostat connections cooked,
next, the timer connections,
next (over a period of lots of months) I realized that the wires 
connecting everything inside were way too small.
Finally, I just used the original fan wires, and throw out all the rest.
The heating element will never burn out (my opinion of course) so I 
connected some 10 gage wire to it.
This plugs into a switched outlet, so I can turn it on and off as needed.
The fan plugs into a switched outlet (separate) so I can switch it on 
and off by itself.
This means two cords going into the TO.
The original runs the fan only.
The heavier one just runs the heater.
You may want to upgrade even further, like I did.
The heater switched  outlet now plugs into a watt meter, which plugs 
into a Variac.
Great control!
I find I want to use power around 1500 watts just getting to 350 F, 
after that it is surprising how little power is needed to control the 
profile.
Always less than 1200 Watts.
Oh, the motor finally burned up!
Just stupidity.
I Usually leave the fan running for half an hour to cool everything down.
The day it burned up I remember now, I put the TO back on top of the 
roasting chamber, and killed all the power.
That melted all the wires inside, including the motor wires.
It is good to keep a spare TO for emergencies such as this.
Oh, I use a 1475 Watt Galloping Gourmet, but I suspect any TO will lend 
itself to these mods.
With this set up I usually roast about 550 Grams, so I end up with a 
pound of roasted beans.
It will easily net a pound and a half of roasted beans.
Limited by the size of the roasting chamber.
