RPM will stink the kitchen up if i do bigger pieces, so i learned to take the pieces out of the oven (with her oven mitts) and go into garage quickly before part cools off.
now if you begin putting dirty, greasy parts in the oven, THEY may stink the kitchen up - i have so far only been baking sandblasted, cleaned parts which have no odor.
i will be in a dilemna when i have to do "dirty" parts - then i may have to invest in an old oven to put in the garage.
i also found that the RPM works best when i have the oven preheated to 200 degF, if i set it at 180 it's marginal.
