Okay, so I'm not new to building, but I've never built anything past twisted and parallel builds. Is there any way to calculuate by hand a rough estimate to a fused clapton build without a calculator tool?
Resistivity formula?

You'll probably get more response in this forum:

If you want it moved, report your post and ask a mod to move it.
Can't help with your question, as I don't use clapton coils anymore.

Ah thatnk you! I'm still learning this forum formula. It's different from reddit but more useful for meYou'll probably get more response in this forum:

The outer wrap does not carry any current, if you can calculate the core resistance then you are good to go.
Or use steam-engine
Or use steam-engine
I've tried steam engine but it doesn't factor in the coil diameter. Nor does it calculate the change in mass with wraps. It just gives ohms/inch or ohms/ft . So I tend not to use it, if there was a formula to calculate it out that would be easier for me
input the coil diameter in the left side box
Wire wizard | Steam Engine | free vaping calculators

Steam calculates the coil’s outer diameter and gives a reading in mass. On the Coil Wrapping tab, click Advance to view more info on the coil you are trying to model. Or use the Wire Wizard tab
Maybe I'm just not getting it? Last time I remember using the wire wizard it didn't gauge accurate readings. Was frustrating to me
Steam uses set metal properties to calculate. If your metal properties do not match, or are even close, then there will be discrepancies. You can enter custom properties should you know these.
Okay so that clears up why it was always wrong. Much like a syntax error. Thank you!
I think Steam Engine's Wire Wizard is a reasonable approach. Beyond that, I guess you could whip out your certified milliohm meter and measure the actual wire you are using, do the calculations of length per distance of each wrap, calculate the distance of the clapton wire, calculate the parallel resistance accounting for leakage. If you mod is using PWM you could consider interelectrode capacitance and coil flux reactivity. Naw..... not today.
Steam engine is a good reference for coil winding and I use it all the time. For complex coils your best friend is a good volt-ohm meter or your mod's resistance readings (after the fact). The most complicated coils I have built are just single and duals. At the low wattages I vape I couldn't heat one of those designer coils to a decent vape level, anyway. 
Not exactly a syntax error but understand what you are eluding to.
Both the Coil Wrapping and Wire Wizard app allows you to see the resistance per length of the wire Steam is using for its model. To achieve any kind of accuracy, your wire should closely resemble this. You can also enter custom wire properties.
Steam is just a guide that will give us an idea on how our coils will work. It does not take into account other influences such as the internal resistance of your mod, atomizer or even temperature should that come into play. Mod’s and Ohm meters may also not be 100% accurate in what they read.
Yeah I maybe good with basic calculus but I won't sit still to do a 30min equation like that. I also use mostly parallel mods or tube mods. So the most I tend to vape at is .08 to .13 ohms. If that gives any narrower range to help out. I think I could also just use my GENE chip and get a rough estimate of a clapton coil starting from 5 wraps to 8 wraps per single coil and gauge that way using an avg right?
Pretty much. Ya gotta figure you are going to put it on a mod that puts out about +/- 10% tolerance in VW, TC, or whatever and "reads" resistances within about 5%. Ya really don't need to try to get it down to 6 significant digits. As per an above comment, remember each core wire added will divide that average by number of cores. The clapton wire really is insignificant and is mostly heated by heat conduction not current passing through the wire.
