Wondering If I can and a 3rd liquid to my extractions that will separate the NP-solvent layer from the basified layer, so that when I pull I have no chance of pulling small amounts of basified H2O into my final product. I'm assuming this means I'll have to roll my jugs for a slightly longer period of time to get the proper amount of contact needed to fully extract the spice. Maybe a polar solvent?

What kind of third liquid?

If your layers aren't separating, simply add more base. That's all you need to do. There is no need for whatever third liquid you are theorizing.

You might want to look in the wiki @ vovin tek, step 7, the sodium carbonate wash. This is an easy way to clean your solvent pulls of any possible residual lye.

Advice: Do each S. Carbonate wash on your solvents as fast as possible. 30 seconds max each one.

It's not because they aren't separating, I'm for sure using enough lye, they separate just fine. I just wanted a buffer, it's easier to add a 3rd layer than do a carbonate wash. Thanks.

Adding a polar solvent like dcm will just sink to the bottom. How in any way is that going to help you? I feel like you are overthinking things. Sometimes thing's aren't easy, but that's OK.

Whats the differance between step 7 and 9 in vovin's tek? don't they accomplish the same thing? Also, how does one separate naptha that is "clear as glass" from water?

If you look at a slight angle from the top or bottom you can see where the two layers meet. Even though they are the same color you will see the separation.

..adding a third (or more) solvent/liquid is like liquid partition chromatography..based on finer differences of solubility characteristics, and often using 'buffer' solutions of acids at different pHs..a chemist could explain it better..
.

You only have to worry about it if there's a layer of water hanging out under the naptha, and then you'll see the bubbles at the bottom of your precipitation container. A little salt (get pure sea salt or lab grade NaOH, not that iodized crap) in the mix will take care of that pretty well, and cut down on emulsions. I actually salt every extraction for stability and zesty flavor. Helps my yeilds a bit too. (you can rinse the salt in your solvent and evaporate on clean glass to make sure there are no contaminates that will make it to your end product)

Easier yet, recrystallize your final product using any of the re-x tek on the DMT-Nexus Wiki (there's a link on the page header) using whichever method will work best for your situation, and remove all doubt!

Happy Travels!
