steam engine question

[socalsailor]

When calculating builds on Steam Engine for parallel builds, is the wrap count the total of wraps counting each strand, or total wraps for the unit of strands?

Example: I want build X using 2 parallel strands of 28g Kanthal, and for my given resistance, SE says use 14 wraps. Is that 7 wraps with parallel wires, or 14 wraps counting the parallel wires as a single wire?

Thanks in advance, guys. I'm trying to experiment with some creative builds and I want to waste as little wire as I can on missed resistance.

7 wraps with the parallel wire, so you'd end up with 14 actual wraps split between the two.

Edit: I read that wrong. If it says 14 wraps you wrap both together 14 times. And would end with 28 wraps between the two. Which is way too much from my experience.

Yeah, that is a ton of wraps, I just pulled a number off the top of my head. But thank you, I couldn't find that in the user guide.

For multi-strand users... if you have two (or more) wire strands per coil, even though they alone technically qualify as dual parallel coils, the program considers it a single coil... when you click the "round, twisted/parallel" option. It's not a dual parallel build.
In this instance, you click on the "material profile" box and click on "round, twisted/parallel", and in the "twist/pitch" box, you leave the number '0' (zero)... and set the "Set-up" to "single coil".

If you have four strands making up two coils... then in "Set-up" it's considered a dual parallel build.

Understand?

Yup, but that wasn't what I was asking. My question was whether the wrap total is wraps of each individual wire, or if the algorithm considers the parallel wires to be one unit.

I built a 28g parallel today with 6/5 wraps around a 2.5 mm screwdriver and came at 0.5 ohms,just like SE predicts.
If you look at my coil,you can count 12/10 wires from left to right.

parallels are consider one unit if you check it on the box in SE

Nope... same as a set of parallels with separate ground posts. The program takes that into consideration when you click parallel profile and zero pitch... and calculates as it would for a dual parallel "set-up", unless of course you're using 4 wires.

Yep... 6 per coil, 12 total.

Ok. Now to figure out how to fit a 28g quad parallel into a Mutation X v3...

Cross your fingers, all, this is bound to be a challenge.
