If you just want to distill alcohol from water, buy yourself a set of reflux/distilation glassware. You heat up the mixture to i believe around 60c to boil off the alcohol, that evaporates up a tube, goes through a condenser then collects in a seperate location. You won't get 100% pure alcohol, but it will be close.
This is a basic schematic
Its something i've done in a lab a thousand times, nothing like creating your own super mix vodka.
Part numbers, depends on how much you plan on distilling and what you want to spend. You can do the above with a length of clear hose, a saucepan, therometer and a couple of mugs, or some custom lab glassware.
