Correct. The screw has a hexagonal hole in it and the L-shaped tool is hexagonal and fits into the hole. You'll most likely get a bit of a whistle as you tighten the draw. Just the nature of the design.
Well... *as far as I can see*, there's no screw in that other aperture, but it does seem to be hex shaped; however, again, *as far as I can see* neither end of that L-shaped tool fits that aperture; it's hard to say for sure because I have to hold a magnifying glass to see if I'm getting the tool into that aperture, so that means I don't have a spare hand to hold the kayfun in place as I try to get the tool into the aperture. So, I'm not sure what to do about that, except just accept the airflow as it is, which is a bit too airy for my liking -- actually I find the draw from a carto to be just about right, very similar to the draw from a real cigarette, and that's a good deal tighter than the draw I'm getting from this. I'm going to try this again when my husband gets home; he sees up close much better than I do, and may be able to tell if the tool fits, if it's actually doing anything, etc. All these little tiny things are not very friendly for those of us with middle-aged eyes -- by far the hardest part of all this with the kayfun was getting the wire around those tiny screws! But this thing with the airflow may have to take precedence in difficulty even over that, since I can't really even tell if the tool is going into that hex shaped aperture.
You most likely have another source of cotton that's sterile and doesn't need boiling. Q-Tips. The amount of cotton on the end of 1 swab is more than the necessary amount to wick a Kayfun. Just tug it off and work it, tugging gently to form it into a wick. I find about 60% is the right amount. I just tug it, getting it to stretch out and elongate into the general wick shape. Then tug off just under half the width. Wet an end to thread it through the coil. This for my 3mm coils. Smaller coils need less. If you can't tug the cotton back and forth through the coil without it deforming the coil or pulling on the legs, you have too much cotton.
Actually no; when we moved, all our Qtip bins got emptied into one large ziplock, so they're absolutely not sterile or sanitary. I used the P&C yarn, boiled it twice this time instead of just once, and let it dry thoroughly before trying to use it, and it seems to be working very well; I'm definitely getting a lot more flavor now than I was with any amount of silica. I don't know the mm of my coil; I used a 7/64 drill bit, but have no idea how that works out to mm. I pulled a loop of the P&C through the coil, and although it contacted the coil as it pulled thru, it did not deform or misshape the coil whatever, so I guess that's about the right width for this 7/64. When I pulled it up and got the bottom part of the chimney attached, I trimmed it to *just* a tiny bit emerging from the bottom part of the chimney, then tucked it all in as Busardo demonstrates, and soaked it with e-juice; I might have over-soaked it just a tiny bit, there was a tiny bit of gurgle at first, but it worked itself out within a few soft draws, so now no gurgle.
I'll try this for a while, and if I get dry hits, I'll know it's too much cotton; I've been over and over that territory with my T3S coils, so I know all too well what that tastes like -- 8-o -- but so far it seems ok. Although I definitely get a more "saturated" taste from my cartotank, so I know this really is just too airy, but have no idea how to rectify that while I'm here alone, without an extra pair of hands to hold the kayfun or good eyes to see if that L tool is actually doing anything. My husband may have a smaller version of that L tool, that will actually go into that hex shaped aperture, because this one really doesn't seem to fit at all.
Thx!
