Aluminium Profile Type Router - Initial questions

[Doddy]

The power of the internet! One of the key attributes of toroidal transformers is a very low flux "leakage" which will limit any potential induced current. I understand the argument but would challenge the actual risk - if I had a toroidal going spare I'd set up an experiment (it's interesting, and this is the first that I've heard of it, and the evidence from the internet looks to be more anecdotal than academic). Actually, because of this thread I've ordered a toroidal just for this experiment - I'll report back in a few days. My thoughts are any current is likely to be measurable but insignificant. The risk can be mitigated in any event by isolating (air gap) the top of the bolt from the chassis to avoid the short.

Edit: What Clive said. The more I read the more interesting this experiment might be.
