I'd say definitely yes. Check these links:

there's even a group/mailinglist somewhere.. but I don't recall
where / what is its name, sorry.

True, but if you check the main page of the 2nd link I gave
you, you'll see that other than telling you how to make a DIY
toaster oven they will gladly sell you one for ~$4500. While
for direct experience I do agree with your affirmation above,
I think that in this case the "DIY" is well worth.


>Will a standard domestic three phase oven work for this if temperature c=
ontrol is added?

Sorry, haven't tested it yet. I made sure though to buy the
"hottest" oven I found, just to have some good margins. My
oven says "260C" as the hottest selectable (by hand so far)
temperature. Also, I bought a oven with a fan inside, imagining
this is a good thing. :D

In fact. Or use a solenoid/motor to automatize the process. ;)

uitable toaster oven? (hmmm.. getting interested here... ;-) )

Above. ;)
