Warped Castings caution re microwave


Rob Kirkham <rdkirkham@...>
 

Dave, if the old grey castings you have are dark grey, they are the ones filled with metal, and I doubt it would be a safe idea to try to flatten them in the microwave oven. They could easily cause a minature electrical storm in your oven, and probably fry it - not to mention ruining the castings.

The other method that works with some resins(I don't know about the
older Westerfield resin you have), is to use the micro-wave. 7-9
seconds at a time to heat up the item and let cool.
