I bought my first mod and rda 2 months ago, & I have been building the same basic 26 gauge 6 coil wrap at .33 to .34 ohms. I am a little sketchy on getting the power up or down. Does anyone have any input about what the effect on the resistance would be to add more wraps or less, or to use a thicker gauge wire? Thanks.

Welcome to ECF! Pull up a seat, a drink and a notepad...
More of the same wire will raise the resistance. If this is a mechanical mod (unregulated), then that will also cause less current draw, which equates to less power, if at the same voltage.
Thicker gauge wire of the same material, will have less resistance at the same inner diameter coil and the same number of wraps. The resistance is created by the material the wire is made out of... more of the same material equals less resistance.
Some good reference places...

EDIT: Just to clarify "more of the same material equals less resistance". This is in reference to the thickness/gauge of the wire... not the length, that should be obvious, but I want to make sure it's clear just in case.

This will help answer your question. It also allows you to see what effect different resistances will have on your battery and whether its capable of driving the load.

Well a dual coil - each coil 26g 6 wraps 2.5mm gets you 0.4Ω
More wraps at the same gauge will get you a higher resistance. Less wraps will get you a lower resistance.
Thicker gauge wire at same wraps and diameter will get you a lower resistance & a thinner gauge wire will get you a higher resistance.
Howdy,
Welcome to ECF
As for the building of a coil, a lot goes in to play and calculators can give you some of the answers you seek but don't really answer questions in a sense.
I must warn though, as mentioned please do be careful when attempting to play with RDA's or RTA's as you can exceed the amperage limitations of your batteries without even knowing it. That being said staying around the .4 to .6 ohm will not stress to many new batteries on the market today.
It boils down to one truth, Ohms per inch/foot of wire. The lower gauge will have a lower resistance resulting in a lower ohms per foot of wire however...driving that system will increase amperage requirements. The size of your coil wraps increasing will increase the amount of wire needed per wrap thusly increasing the ohms (more wire used concept).
Also keep in mind that your wattage (heat) will increase with the drop in Ohms, typically speaking up until a point all wire will reach a maximum temperature eventually however the lower the resistance just means how fast it gets up to that maximum temperature (lower ohms means faster heat up). Finding that right mixture is pretty easy on a VW/VV mod however on a mechanical mod it requires a bit of tweaking to get the ideal vape, this is where your calculator app's get used a lot.
Hope this helps out a bit, feel free to hit me up in PM should you need any questions answered or advice, I've been at this since long before RDA's and RTA's were even a concept on the drawing board.

Whatever you do, make sure you have a reputable battery, Sony VTC4/5 or Efest High Drain......... Please for vape's sakes, check your resistance before trying to chase clouds, and plus please please do not try to run a .1 ohm build to chase clouds on a no name battery. Use your Ohm's Law calculators and do some research....
ALSO, A Higher Resistance at Higher Watts does well also.... Just saying.
