heating a bearing in the microwave
NeoTech:
You gotta remember this guy, "Arduino vs. Evil" basicly lives for doing crazy ****.. Been following his videos since the start and he is effin hilarious.. But somethings, well common sense is really a aquired skillset for doing half of the **** he does. ;)

Check your part for color as you get close, and/or use an infrared thermometer. Adjust thermostat, as required to get what you want, and plunge when there. It's a nce even and slow process -- less danger of overshooting.

I use an ancient toaster oven (it came with an old tour bus I bought to haul the racing car around in). As the thermostat is very hit & miss, and i like to do reflow soldering in it, which doesn't like being massively over-temperature, I just added a cheap(ish) thermocouple, built a little arduino based device which reads the temperature out on some LED digits. Works great! If anyone's interested, I'll do a write up & costing.

Hey cool Ade, that sounds ideal, and I hadn't thought at all about re-flowing with one.
btw -- I wasn't recommending heating ball bearings at all here -- I've never done it -- just questioning in general why people would use a microwave oven for heating metal parts when simpler and cheaper small electric ovens are available, often free, and can easily fit in the shop. Like I said they work for baked sand cores, tempering, too, and now even solder re-flowing.

:) I be one Ade .
Just as a side note , If I need to heat a bearing up (or anything else without frying it) I just use a hot air gun ,cheep and works a treat :coffee:
