Introducing the Precise Strata RDA

[fordski]

OK testers I assume you know most of the ins and outs of coil building.... So since the Strata only directly screws on as a top cap of my ELA I guess there is no way to test the ohms of a coil I build? I have an ohm tester but it requires that you screw the rba into a 510 thread... So how will I know the ohms of a coil I build? Is the a chart or something that gives specs like use this kind of wire with this many wraps for a approx. ohms of the rba atty? I will need help as I am a rookie in this field of vaping......

I would suggest the use of a multimeter that allows you to measure the resistance. While charts can be helpful in determining the amount of resistance for a specific length of a specific gauge of wire, a multimeter will also determine if there is anything wrong such as a short (no resistance) or a poor connection (high resistance)....

The little black box ohm meter won't work for the reasons you stated but you can use a regular multimeter to test the ohms..

It will work if you have the little black box and the 510 adapter which has alligator clips coming out of it. I think I got the 510 connector from ?? Can't recall but ill think of it Also, you can just use a multimeter with probes or clips on it.

With the current design no. But if you can change the deck like this you can. Not sure if the center post can have a hole though.

Please dont' take this as a flame, but taking 3d rendering software with no in depth concept of what it takes to machine something like that is dangerous. To machine above deck like that, though not impossible, is very in depth, would require a 24 tool station turret minimum and/or dual machines(a y axis lathe and mill) and it could double the machine times of a unit that is already pushing the ragged edges of machine time and cost feasibility. In other words, though it's easy to just "draw it up" the realities of machining it are far different.

Step 1. Remove all posts. Wrap your coil leaving tails on each end ( I use a tension pin pressed into a piece of brass). Make tiny loops on the end of your coils and snip away the excess. (I wrap the end loops on the same pin I used to wrap the coils on).

Step 2. Put the coil loop around the outer post, hold the pin upside down/sidways so the coil doesn't fall off:

Step 3. Turn the Strata sideways or inverted and screw the outer post in with the coil on it, but don't tighten all the way. Swing the other loop over the center post screw hole and screw in the center post. You can now tighten them down and then bend the coil to where you want it exactly. If doing two or more coils, do the other outer one(s) first and swing them all over the middle screw hole and insert the center screw and tighten down

Dual coil example. I'd pack the back side with wick too and saturate with liquid (you can also run the coils on opposite sides too, you may find better distribution that way:

I guess I have to get my multimeters out. I'll miss using my little black boxes. Unless, I get one of those 510 adapters with clips. If anyone sees them, let me know? Thanks!

I know where those 510 alligator clips come from.........Vapormoon

All you need to do is to know the resistance of the wire your using (i.e. 28g kanthal A1 is 0.44 ohms/inch) and the total length of wire your using. Using 1.8 inches of 28g will give you a resistance of 0.792 ohms. Now comes the tricky part...calculating based on the diameter of your wick. I generally wrap mini-coils (2mm, which equals 0.12"). Each wrap of the coil is essentially equivalent to the circumference (pi x diameter). So the equation for calculation how much wire is used in a 5 wrap coil is pi x diameter x number of coils x resistance of wire. So a 5 wrap coil of 28g kanthal and a 2mm wick equals (3.14)(0.12")(5)(0.44 ohms/in) = 0.8289 ohms. This does not take the legs into account so the resistance will actually be closer to 0.9 ohms. The calculation also uses the inner diameter of the coil so the actual amount of wire used is slightly more. When I calculate this way and then test on my friend's ohm reader, I'm always within a 0.05 ohms.

EDIT: or like the others have said, use a multimeter if you have one.

Never knew such an animal even existed.. LOL

 

[Cucco]

I always use the tester. When I place the coil. And, again, after I put the evaporation chamber on. I had a short once. It discombobulated my KFL, and startled me. Easier to just test her. Glad it happened on my beastly ELA.

 

[raqball]

I have a decent multimeter that I snarfed from RadioShack and I have one of the little black box ohm meters..

I use the MM more than the little box though..

Those clips are pretty sweet if someone has the black box tester and wants to use it with the Strata..

Thanks......I've got a lot to learn.......I am interested in 2.4--3.0 ohm coils since it will be used with a Kick2 set at 11 watts.....

You will be fine Riverboat..

Get a cheap multimeter or score them alligator clips for the ohm meter you already have and rock on!

Plus, you have this awesome thread and all the helpful Super T peeps to assist you..

Huh. Barring interference from babies.

 

[icucme2]

I like the holes in post because its easier to feed thru and tighten.. Wrappin around the post is cool too. Only draw back is when u have the coil wrapped and u tighten down sometimes the coil slides iff with the turnin pressure

Will PrecisePlus Strata fitt to Simplicity?

No, different threads. Also, the Simplicity threaded Strata will not fit the ELA extension tube.

 

[OnTheFidele]

Thanks for the demo, David. The Strata looks much stronger and easier to coil than I'd imagined!

I'll finally be tucking my mini screwdriver away soon

Remember that your multimeter will read the resistance of the entire circuit, including the leads/probes/clips..my expensive Fluke true RMS meter adds .1-.2 ohms with the probes. Cheap meters will add more, and aren't always accurate.

I always touch the leads together 1st and make note of the reading.. Then I deduct that amount from the atomizer reading..

Ie. If touching the leads reads .3 then I deduct that from the Atomizer reading.

So if the Atty reads 1.8 then I actually have 1.5
