Same here with regards to the Lemo, I have to turn the power up to 35 watts or so to get decent flavor. I think the chamber is just too big.

I'm having problems with my K4 vapor-locking and drying out the wick. I have to crack the fill cap to get any bubbles! I'm not sure what I'm doing wrong, I've got the wicks tails trimmed down to hardly nothing, and they're bearly touching the deck!

edit: when the wicks are wet, the K4 in TP mode is absolutely fantastic!

Please forgive me for asking, but you didn't forget to turn it clockwise several times until it stops to open-up the juice flow, did you?

Yeah, I've got it open. I've changed or adjusted the wicks in this damn thing so many frickin times, I'm about ready to give up! Unless the tank is almost empty, it won't flow juice! I've tried every style of wick I can think of (all Rayon, of course) Currently I have one little thin tail In between the juice holes, I can literally see both juice holes, and it still won't flow!! I'm using 100%VG, but surely that's not the problem. I'm tempted to pull the wick out completely and see if it will flood!

Of course, I already had to do a little modification :) I thought maybe my bushing was causing a problem, so I removed it until I can get this flow issue resolved.

No more spring for me

I made the flange with .2mm of pre-load to insure good connectivity and allow for variations in the numerous pieces involved, some of which that didn't require close tolerances in the initial SM design. So as you can see, this leaves a .2mm gap when my juice control is open, which isn't enough to effect anything. With usage this gap will probably decrease as the cumulative dimension changes due to the deformation of the plastic parts involved.

I don't know man, why it wouldn't work :confused:

I still use that Silver plated Beryllium-Copper spring and one and only built that I had in it. Here is that build after 7 days of vaping. 30 Gauge Ni200/30 Gauge Kanthal and trimmed tail Rayon.

This is ToBeCo clone without any modifications. The only thing I did, I removed that Airflow Adjustment screw to open up the flow of air.

If I understand correctly, by raising that Juice Control section up it will disconnect the Positive terminal and therefore turn the atomizer off.

I think, this is pretty good. You start unscrewing the atomizer and shot off the juice flow and turn it off electrically. Ingenious. :toast:

Every time you guys mention beryllium I think of the cautions I used to got through working on transmitters that had beryllium plated power tubes. It can be toxic at higher levels. I don't know how much extra your might get from it being in am mod, but food for thought.

We wear heavy duty respirators when we machine that stuff. It's supposed to be bad news when you breath the dust (or the smoke)

Edit: I never bothered with the respirator: it got in the way of my cigarettes!

What size coil is that? I had a 3.2mm twisted 30awg, but dropped to a 3mm for less wick, and I've got the tails up off the deck by probably 2mm! I'm seriously going to cut the damn tails completely off and see if I can get it to flood this juice

That's 3.0 mm coil.

Finally, I was able to fix conductivity issues on two other cheap Kayfun V4 Clones. I had to lathe one of the parts in it.

And here is my exact build. Step-by-step. It doesn't have any wicking problems.

I cut my skinny little wick tails 1/8" ABOVE the deck, and the thing still vapor locks! I have to crack the fill cap to get any juice bubbles and it still won't flood.

I've had it completely apart several times trying to find something wrong, but I'm stumped. It's like it wasn't designed for 100%vg juice

Is it real or clone?

I finally got it to flood, but I had to completely remove the fill cap, and it really wasn't that bad of a flood. I would've thought the tank would have emptied in a matter of seconds.

I guess I'll try some thinner juice tomorrow, all my stuff is at the shop. Damn, I really don't have much thin stuff, mostly high VG. I'm sure I'll find something in that box of old juice in the freezer

All my juices are 70% VG - 30% PG as well.

Well, learn something new everyday: It turns out that I didn't have ENOUGH wick!

I removed the wick completely and the chamber would not flood unless I removed the fill cap and let it sit for a while. So I re-wicked it making sure I had Rayon touching all four juice holes, and it's back to bubbling and making sweet vapor. So I guess it literally has to pull the juice through the juice holes to work properly. Who'd a thunk it?

Sitting down, facing forward.
I dunno, the air flow is great, build deck is fine, but 3ml on a cloud producing RTA? What were they thinking? A longer glass tube and taller chimney would fix that without changing the geometry of the chamber. And still, a bottom fill! When are the manufacturers going to get the idea of top fill?
