Newbie PSU calculations

I'm pretty sure if somebody can manage to wire up a functional CNC machine, then they can manage to wire up the required bits to create an unregulated power supply.

That's true, but the mistakes can be more energetic than in other parts of the machine. The first component to install should be the mains fuse, suitably rated for the job with an allowance for inrush. In the UK this can be in the plug-top but in other parts of the world a separate device is needed. This helps prevent backlash... from the rest of the family when the house goes black, taking Netflix with it.
