    Yes it's flexing and the cuts are already light as is - 1mm to 3mm deep. If I go 0.5mm then I get those "molten" threads I was talking about. Plus my router is only 750w so it doesn't have the grunt...

    I'd suggest you were testing from +12v to -12v and from +5v to -5v, in which case it would show you 24v and 10v respectively. In that case current rating is minimal, milliamps rather than amps....
