When selecting a transformer, it is not sufficient to just get a 1:1 ratio. The core must not be allowed to saturate. If you take a 120 VAC rated 1:1 ratio isolation transformer and try to operate it on 240 VAC it will likely saturate. When the core is in saturation the normal back EMF does not

Steve, of course, you can't very well connect a 120 V transformer to 240 volts without expecting a minor catastrophy (especially considering the power class we are talking about). In the UK, they have generally a nominal 240 volts mains supply (don't know about the tolerances). On the

I'd use your CNC lathe and custom grind a bit for wood out of high speed steel. I'd probably grind it similar to a wood lathe parting tool but put a radius on the tip. I'd be throwing out a lot of wood if I had to make violin pegs on a wood lathe by hand. Dave On 9/7/2011 5:03 PM, Kirk
