Older Folks and Vaping Front Porch - Part Three

[bigbells]

I can only do a good job of building a coil when I use my Coil Master jig. Eyes just aren't good enough, even when I use a magnifier, to see what's going on. With the Coil Master I don't have to see... just make the coil, take it off, put in on the head and wick it with KGD cotton. My eyes ARE good enough to get the cotton in.

A related question: it seems logical to me to install a horizontal coil with the legs "underneath" the coil rather than on the top side. I've never done it the other way around (maybe it's impossible) on my Kanger Subtank rebuildable heads. Doing it with "legs up" would put the coil closer, possibly too close, to the center hole, is what I'm thinking. The screws that hold the leads are both at the same level on the Subtank.

Am I doing it the way that most of you do it?

Dave, I'd have to do it to know for sure, but I'm pretty sure that when I do em, I have one that comes from underneath and one that comes over the top. I rotate the cap away from me when I wrap, not sure if rotating it toward you makes em both come off the same way or not

I have to take my glasses off to do my coiling and wicking.
Can't help on the subtank, sorry. Just a tootler here.

No, the direction in which the coil is wound has nothing to do with where the legs come off. If you've got one coming off on top and one coming off on the bottom, that means you've got something-and-a-half wraps. If you did a whole number of full wraps and no half wrap, the legs would come off on the same side of the coil... in opposite directions, but the same side.

With half wraps, the legs point in the same direction but one is on the bottom and the other is on the top.

Any further explanation might involve math, so I hope you grok.

I'm not sure which way the legs are pointing, but I just use my drill bit or jig to pull the coil up from the center hole after I have everything tightened down. So, I guess I've never been too concerned about the direction

This may be one of my problems. One post is higher than the other.

I like to have the straightest and shortest legs possible, so I try to mount the coil where I don't have to move it. You can see what I mean about the legs being below the coil in the picture. I circled the leg on the right because it doesn't show up well in the picture. You can also see how if I flipped the coil over before installing it, the coil would be below the legs instead of above the legs.

Most of my coils are for KFL, R91's, sub-tank type decks where I want the legs coming off the bottom of the coil. On some drippers because of the geometry of the +/- screws you might need one leg coming off the top and the other off the bottom. But for KFL type decks heres my

I mainly do clockwise wrapped coils w/ both legs coming off the bottom .... the middle picture.

Sometimes for the heck of it, I'll have my legs coming off the top ... kind of/sort of ... like in the top coil also wound clockwise. But then I need an extra step to bend the legs into position. See the bend/kink in the leg in the top picture. I do that by putting a flat nose pliers over the coil while it's still on the mandrel and bend the legs into position.

What I really prefer is winding my coils counter clockwise. But the 2 piece coil jigs are a bit fiddley to wrap then counter clockwise. Or you need a left hand screw. Or just do it by hand on a drill bit of sumpin'.

Why counter clockwise? Look at the little circles that represent the +/- screws. When wrapping the legs around the screws, you can do it counter-clockwise, then when tightening the screws (a clockwise motion) ... you're not pulling the coil out of position when the screw starts trapping the leg and the leg sometimes twists with the screw disturbing the coil.

An advantage of the kinked leg coil ... I can wrap it clock wise quickly on a jig ... but I can wrap the legs counter clockwise around the +/- screws ... like a counter clockwise wrapped coil w/ legs coming off the bottom.

 

[bigbells]

When I make a clockwise horizontal coil, the legs go under the right hand side of the screws, so that turning the screws does not pull the coil out of position.

If I flipped the coil over so that the legs came off the top of the coil, the legs would have to go under the left hand side of the screws, where there would be a greater tendency for the coil to move as the screws were tightened.

Excellent...

I would have thought that a 1/2 wrap would make them stick out opposite directions, but believed you, then Mike's pic/notations helped me to visualize what you were saying, so thanks!

That's pretty much how it's shown on Kanger's site, Dave, with the lead in position to be drawn into the screw when tightening.

OK, not sure why what I'm describing doesn't match. I wrap my coils clockwise around the shaft of the Coil Master, and when the coil is installed with the legs on the bottom side of the coil, the legs end up the way I want them: in position to go under the right-hand side of the screws rather than being pulled in to the screws from the left-hand side of the screws.

The Coil Master, as Mike has said, is made for clockwise coils because the holes through which the wire is inserted are angled relative to each other to start in a clockwise direction.

I can see that ... it will depend on the 'length' of your finished coil as to whether the legs will 'natuarlly' align for putting them to either the left or right side of the screws. And obviously the length will depend on the gauge of wire, number of wraps, and spacing between wraps.

Clearly there's something that we're seeing or understanding differently from each other. No matter how short or long my coil is, the legs naturally go to the right-hand side of the screws rather than the left-hand side of the screws. If the coil is long, the legs have to be bent back a little to reach the right hand side of the screws, but they'd have to be bent back a lot more to reach the left hand side of the screws.

Maybe this is something: I sit my coil perpendicular to, and at the middle of, the imaginary line connecting the centers of the two screw heads.

Maybe it's our decks being different. What are you building on?

Or maybe your just naturally more left and I'm more right (as in direction not correctness)

Tomorrow I'll post a picture of the coil and deck before attaching to the screws. Then we can see where we're not understanding each other.

 

[bigbells]

I suspected the same thing and edited my previous post to explore that possibility. I'm building on a Kanger Subtank Rebuildable deck. The coil sits in between the two screws but perpendicular to the imaginary line between the two screws.

Good thing you don't have the money. I've got at least a dozen coffee mugs that I NEVER use because they're too small. My Aladdin coffee mug, the only one I use, holds 52 ounces. I've used it ever since my 64 ounce mug broke.

yeah I know you'd never use it, but it describes us so well! lol I thought it was funny
