Re: [CAD_CAM_EDM_DRO] Re: melting aluminium

One of you electrical geniuses want to try figuring out how much electrical
power I'd need to melt aluminum using an AC magnetic field? Maybe I could
build myself a simple electric melting furnace and be able to get my
castings for the CNC (and other) machines done a lot quicker. Perhaps my
portable generator and a step up transformer could be used as the main power
source?
