Dedicated oven under all circumstances. I’m sure there are nuances here, but my general answer for the first question is no. Dedicated oven under all circumstances.

Personally I love lead based solder because of how nice it flows. The lead free stuff is okay but it's just not the same. If you use a toaster oven for soldering write "NOT FOR FOOD" on it like I did and never use it for food (RoHS or not). My toaster oven was $15.00 at Walmart and was inexpensive enough to buy a second one for food. Unless it’s RoHS compliant it has lead in it.

Is it non-lead? Or do you have an oven dedicated just for that use? Is the solder safe to use (health-wise) in an oven? Is it non-lead? Or do you have an oven dedicated just for that use?

I also tend to watch my boards carefully in the last minute to see if things are reflowing. Of course, since I don't do large batches the way you do its probably easier just to have a recipe and go with that. I'm sure there is a great deal of oven variability though. I think I started watching so carefully because i didn't like the smell when I burned my boards... i use 325 for about 3 minutes.

Although the toasty look on boards can be somewhat endearing... wowzers — your bake cycle is quite a bit longer than what I use… Although the toasty look on boards can be somewhat endearing…
