  1. A VFD takes mains power in, rectifies it to DC internally, then synthesizes something that looks to a 3-phase motor sufficiently like a 3-phase sinusoidal waveform for the motor to behave as if it is powered by one. The clever bit is that the VFD can vary the apparent Voltage and Frequency and make the motor run at variable speed. VFDs are available for single-phase 230V input or for 400V 3-phase input. If you get a 230V single-phase one, it can run on UK domestic mains. The biggest you'll be able to run from a 13A socket will be a 3 HP/2.2 kW. It's not really worth getting any other size

  3. Would you think one of those air brush compressor work for a wet mist system on your belt grinder? They're small, quite and put out about 40 psi or so.

  5. Quite an honor for the pig! I like the texturing linking the guard and grip.

  6. Thanks, Josh. I feel like a sponge trying to soak all of this up. As I've said a million times before, "I've a lot to learn here".
