Title: Help me out....
Post by: eddy-r3 on July 26, 2013, 03:26:13 PM
Hey guys, right, resistance im a little confused (LOL)

At the moment i have 2 wraps of 0.3 x 0.1 kanthal ribbon, which is reading about 1.2/1.3 ohms, i want to get this down to 1ohms or under. I dont want to make a 1 turn coil LOL so would i need thicker, or thinner ribbon?

Many thanks!

Or a dual coil setup with the same wire, if your atty is able to be set up like that.
Title: Re: Help me out....
Post by: DirkDampf on July 26, 2013, 03:58:22 PM
You could try to wrap some coils in one direction and some coils in opposite direction on one piece of wick so that they cross eachother. This should give a quite low res. but  lots of surface to vapourize liquid.

So if i were to do 2 wraps, crossing over with the same wire (0.3x0.1 ribbon) would this increase or decrease the resistance? Essentially doubling the length of the wire...
Title: Re: Help me out....
Post by: itsmeitis on July 26, 2013, 04:09:57 PM
two runs of the same wire - would equal half the resistance - i.e, if those two lengths are made twice as long, you'd arrive back at the same.
Title: Re: Help me out....
Post by: eddy-r3 on July 26, 2013, 04:15:27 PM
2 wraps @ the moment equates to 1.2ohms (ish) if i were to double the length, that would then equate to 1.2ohms right?

If i were to have 2 seperate wires, both 1.2ohms, that would still be 1.2ohms right? But more surface area leading to a better vape....right?
Title: Re: Help me out....
Post by: itsmeitis on July 26, 2013, 04:16:52 PM
one run reaching 1.2 ohm, would become 0.6 if you repeated it to two runs.
Title: Re: Help me out....
Post by: a1laserboy on July 26, 2013, 04:20:04 PM
Try this http://www.1728.org/resistrs.htm

You would be effectively running 2 resistors in parallel. I'm not sure how having the coils crossing each other would effect the whole thing though.

Diz is the resident electronics expert round here, he should be able to help better.

Post by: itsmeitis on July 26, 2013, 04:21:32 PM
twisted wires also halve the total resistance.
Title: Re: Help me out....
Post by: a1laserboy on July 26, 2013, 04:23:26 PM
True, makes it just like a thicker wire. Didn't think of that - could be a good and easier way to do it.
Title: Re: Help me out....
Post by: DirkDampf on July 26, 2013, 04:24:40 PM
Yep more surface=more vapour output but that also means more power input is required to heat the wire up properly.
Title: Re: Help me out....
Post by: a1laserboy on July 26, 2013, 04:25:48 PM
Thing is, when you wrap a coil, if you have wraps touching, it is effectively shortening the length of wire which is why I said about the oppositely coiled method possibly giving unexpected results
Title: Re: Help me out....
Post by: itsmeitis on July 26, 2013, 04:27:40 PM
probably not easy or practical to create a twisted wire while using ribbon - but - it should probably work to have two runs which come into contact with each other at various points.
Title: Re: Help me out....
Post by: eddy-r3 on July 26, 2013, 11:09:23 PM
Ok, went with 2 coils on 1 wick. Bit fiddly to get setup, but got it down to .8ohm :)

Worked out pretty well to be honest, the only problem i have now is my wick, wicks too well and have to have it vertical otherwise it floods.....Moan if it doesnt wick, moan when it wicks too well, no winning with me! lol

Thanks for help guys :)

Any chance of a pic eddy? I'm curious about this ribbon and sorting the resistance thing myself

How come it's wicking too well? Is it the more wire the better they wick then?

Wicking will depend on the wick and it being rolled well.. The ribbon will perform better as its flat so effectively has more surface area and heats more of the wick

Thanks Gaz, that's what I thought but was just curious if eddy had any tips or things to avoid particular to his experience of it. I want to get some of this ribbon and I know he uses AGA T2's same as me so he might save me some grief lol

Me neither, just can't seem to get the gennys working with my mech mods properly - just don't seem to pack any punch. I still don't think I've got the resistance thing sorted out properly. Guess I'm hoping the ribbon wire might come to the rescue  ;D

I'm exactly the same, loads of vapour but the throat hit seems to lack but when on a vv mod at lower voltage it seems fine 😖😖

Hey guys will get some pics in a moment, getting it right takes a bit of fiddling, but oh so worth it!

My AGA T2 has 2 coils of 0.3x0.1 kanthal ribbon, wrapped in the SAME direction just not touching and it vapes...well like a train! Just have to keep it upright due to it wicking a bit too well, ANY tipping and it floods like mad....resistance on this is about 0.8ohm

The RSST I got this morning has 1 wrap of 0.3x0.1 kanthal ribbon and a wrap of 0.2 kanthal wire, resulting in 1ohm

Both of which vape REALLY well, i prefer the look of the RSST against the AGA T2 (the polycarb tank lets it down though, and i find the wicking hole too big (if there is such a thing!)).
Title: Re: Help me out....
Post by: eddy-r3 on July 27, 2013, 11:28:52 AM
AGA T2 first, then the RSST :)
Title: Re: Help me out....
Post by: eddy-r3 on July 27, 2013, 11:33:57 AM
And an image of the RSST on the Sigelei 19
Title: Re: Help me out....
Post by: ilegal on July 27, 2013, 10:05:48 PM
They all look brilliant Eddy, nice one and cheers. I'm guessing you tie of your two pieces of kanthal and then wrap them both at the same time - one turn each? Either way, does sound hard but deffo up for giving this a go when I get some ribbon

On your T2 - it looks like you've got rid of one of the nuts and put a washer in there instead?
Title: Re: Help me out....
Post by: eddy-r3 on July 27, 2013, 11:12:34 PM
Yeah i removed one of the nuts and put 2 washers and trap the coil between, just to cut out any hot legs that may appear! :)

I wrap the 2 coils seperately, bit fiddly, as once you have one coil done, then add another, the 1st one tends to pop out from negative post lol, bit of patience and it gets done eventually, and like i said, works like a charm! Very happy with my RSST setup now :)
Title: Re: Help me out....
Post by: ilegal on July 28, 2013, 12:11:57 AM
Yep, got to get some of this ribbon stuff and give this a go. Cheers bud
Title: Re: Help me out....
Post by: eddy-r3 on August 02, 2013, 03:36:51 PM
So, been fiddling with the AGA T2 and the RSST recently, i just cannot get on with the RSST i find it really difficult to get right as opposed to the RSST, no idea why either! Frustrating just isnt the word for it :(

I like the RSST and looks great on my sig 19, just doesnt work for me, so really, im sticking with the AGA T2 for the time being.

ANYWAYS, managed 2mins on lathe and took that awful chamfer off the top cap of the sig 19 so my aga sits flush, looks a lot better now :)  just need to sort a brass firing pin out, then get some balls and spend the time polishing it up! lol

Title: Re: Help me out....
Post by: eddy-r3 on August 02, 2013, 08:52:55 PM
And started to polish it up, this is 20mins on the lathe with paper from 240 upto 1200, then finished off with some polishing compound (soap) and some K-Roll :)

Need to finish the lock ring and button, got a brass one on the way to with the intention of mixing them up, polishing etc :)

Hopefully will be nice with a brass/SS top cap on the AGA

Thanks wyrm, i tried actually saying that out loud and didnt sound too good....lol

Just need to wait for some bits and bobs to arrive now and ill get the rest of it done, its been tax payment week so a little, er skint lol

ahh, thats where it all falls over  :P

Post by: eddy-r3 on August 03, 2013, 01:34:46 AM
Yeah it does help, you can do it by hand, from what i have seen/read, not something id like to try though being honest!
Title: Re: Help me out....
Post by: eddy-r3 on August 03, 2013, 03:35:30 PM
So, spent a bit of time making a brass firing pin for my sigelei 19, came out alright, need to shave a little off as there isnt any throw on the button at the moment, may extend thread into button so it can be adjusted to some degree and see how it comes out :)

Made a new button to, annoyed as it has a dimple in the middle, will polish it out shortly though! :)
Title: Re: Help me out....
Post by: eddy-r3 on August 03, 2013, 04:01:51 PM
Right finished, saved myself a fiver (LOL)

Only took a few hours...and loads of sweat lol came out well though, works a treat to! To be perfectly honest, i dont really notice a difference, but none the less, still happy :)

See the dimple? Yeah im off to get rid of it...lol

Thanks for help guys :)

With the flooding it can either be that your wick is too loose in the wick hole (so liquid is seeping round the edge when tipped) or not enough mesh used so the hole down the wick is too large and acting like a straw/pipe so when tipped liquid just flows up it too freely.
You need a hole down your wick for the capilliary action but not one that is too large. I find that my wicks can just fit a paperclip or pin in them (tightly) and have had no trouble.
Title: Re: Help me out....
Post by: eddy-r3 on August 03, 2013, 06:49:36 PM
Thanks Al, will give it a go when i make a wick next, as it stands this one is working ok at the moment and dont want to disturb it! LOL

Thanks Ric :)
Title: Re: Help me out....
Post by: ilegal on August 04, 2013, 07:53:35 PM
That 19 looks absolutely minted polished up like that eddy

I tried doing mine with just polishing compound and even though it gave it a nice finish it was nowhere near that polished finish you've got there. I've got the paper coarse to fine so tempted to give it a go when I get chance. I've been meaning to stick a boge on the mod and then putting that in the drill chuck and seeing how that goes - got to be better than just elbow grease!

But yep, excellent looking that
Title: Re: Help me out....
Post by: eddy-r3 on August 04, 2013, 08:26:26 PM
Yeah the problem is with polishing the tube as it comes is that it has a machine finish on it, to get a real polish on it, you need to remove this, going with as you stated, course - fine papers. I went from 240 upto 1200, would like to redo it to be fair as there are still some machining marks if you look upclose and also the locking ring hasnt been done, which again, i will do at some point in the future.

If you go the boge/drill chuck route make sure you dont over tighten it when polishing it lol :)
Title: Re: Help me out....
Post by: ilegal on August 04, 2013, 10:03:32 PM
I'm sure whatever I do I'll screw something up and pigs ear it lol

Still, that's the way it goes and all the fun's in having a bash  :D
Title: Re: Help me out....
Post by: eddy-r3 on August 06, 2013, 04:18:48 PM
So i had some bits and pieces arrive, eventually, been waiting a while.

Anyways, made myself a new cap for the AGA T2 along with a little drip tip.

Polished up and finished with some polishing soap, came out ok, there are a few things i want to change, ie. Smaller air holes, i went with 2 x 1mm air holes, too tight, so opened one of them to 1.5mm and now its too loose.....but oh well, trial and error and what not! :)

Either way, looks better than the original IMO

Title: Re: Help me out....
Post by: eddy-r3 on August 06, 2013, 04:25:34 PM
Thanks Ged, i think with a bit of fine tuning and a little more patience it'll be good, i tend to get 1/2 way through and start rushing to get it finished and make small errors which i have to correct in the end, but thats life hey! :)

Im going to do another in Brass/SS and then get a mixed Sig 19 and polish the hell out of them, hopefully should look pretty good i think, i done a brass button the other day for my Sig 19, looks ok, but odd with the rest of it being stainless lol

Title: Re: Help me out....
Post by: ilegal on August 06, 2013, 04:41:29 PM
Looks great Eddy, tons less fussy than the original. I can't work out where the brass might look best in the cap though so looking forward to what you come up with!
Title: Re: Help me out....
Post by: eddy-r3 on August 06, 2013, 04:47:20 PM
Ill see what i can do, im toying with the idea of brazing some rings on, perhaps 3 thin ones then poslishing it all flush, but could be a right royal pain the in rear!
Title: Re: Help me out....
Post by: ilegal on August 06, 2013, 04:53:08 PM
Or make a brass centre post for inside it maybe, that might be quite cool if you could see it. But I don't know if brass might go funny in eliquid or poison you or something :o
Title: Re: Help me out....
Post by: eddy-r3 on August 06, 2013, 04:56:18 PM
Yeah it would...lol well, at least it would "leech" into the liquid, and free machining brass (CZ121) contains a small amount of lead to make it easier to machine, hence why i didnt make anymore drip tips with Brass on the actual tip :)

But i admit, it would look cool. You could probably use Naval Brass, but a) its hard to come by and b) expensive for what it is! And c) not really sure how it would fair against being submerged constantly in eliquid! LOL :)
Title: Re: Help me out....
Post by: ilegal on August 06, 2013, 04:59:01 PM
Yep, lead poisoning and death might be a bit of a problem hahahaha

Back to the drawing board then lol Sure you'll work something decent out  :)
Title: Re: Help me out....
