I was searching around the forum for a way to produce potassium chlorate from potassium nitrate, and though there have been a lot of posts on making potassium chlorate, I didn't see one on making it from potassium nitrate. I was wondering if one could make it using regular salt and potassium nitrate NaCl + KNO3 -> Na KClO3 (I'm probably not writing this write but it's 12:20 a.m. and I've been working all day, so I beg slight leniency), or sodium hypochlorite (bleach) and potassium nitrate, or some other otc source of chlorine (besides pool cleaner). How could one get the sodium out of the mixture? Or is the whole idea bogus, and the result of an over-tired mind? Any help would be appreciated (including a tempur-pedic mattress, a massage, and ....

No, no and NO!
Lets see...

NaCl + KNO3 -> Na KClO3

I understand your idea, (which I will explain makes no sense to anyone with even a slight background in chemistry), but your reaction does not even make sense! First of all, your nitrogen has disappeared. Second of all, what is "Na KClO3"?
Lets look at the skeletal equations of all the things you could have meant and why they are all bitterly, bitterly misguided.

NaCl + KNO3 -> NaN3 + KClO3
The nitrate anion is stable. Under normal conditions, it will stay in tact and bond to a more favourable cation in solution if available. Both the azide and the chlorate ion need a great input of energy to be formed.

NaCl + KNO3 -> Na + N2 + KClO3
A metal will bond to something as soon as it gets a chance. There is no way that one of the most reactive metals, sodium, is going to be produced free in a reaction like this!

NaCl + KNO3 -> Na+ + KClO3-
Seeing the chlorate is already bonded to the potassium, it is not acting as a free anion. And, your nitrogen is still missing.

So, in conclusion, yes, a totally bogus idea.

KClO3 can be made from hypochlorites, sold as bleach or pool chlorine. The information is abundant. Go search, and learn something before posting again!

My biggest mistake was posting it as an equation. I was deliberately leaving out chemicals that I knew needed to be there in order to cause the break-up and bonding. I MEANT it to be a (as you say) skeletal equation (though to be honest, my nitrogen disappeared because I was to tired to remember it was there), and was hoping someone could fill it in. Obviously, I've got to solids here, (at least for the first one), and as they are both fairly stable, they are not going to magically bond or transform. I need a solution and process to break down the chemicals and reform them. So I was fully aware that as an equations these forumulas were bogus. I also know, from researching (as I said in my post) that there are other ways of manufacturing KCl03, but the question was, can one do it from KNO3?

You can use KNO3 to ppt the chlorate out as KClO3 from an NaClO3 solution, but there's no other magical way (at least that I know of) to convert it into a chlorate directly. Search, and you shall find.
