Ok .. another update here. I've made 3 of these now and they are working wonderfully. I even went back and used 2 of the old silicone caps I made that were leaking like crazy because they weren't "perfect" to make the 2 new cartidges. I've had zero leaks.
My only other concern previously was taste. It seemed a little dryer than the mod without the poly-fill. I ended up making the hole for the atty even larger by using the same #4 punch (from smallest to largest) and making the hole as an eclipse by punching some off the left and right of the original hole I made in the center. It basically just looks like an oblong silicone washer now which is really only keeping the poly-fil from going anywhere. My atty wick seems to fit inside of it entirely now and so far it's not leaking because the poly-fill is kind of circling it. Taste is much better because it's not just touching the
juice, but is sitting in the middle of the small ring of poly-fil and kinda touching the
juice directly I guess.
I just received some new
juice (which is excellent BTW, but I don't think I'm supposed to mention any vendors) and it's a little thinner than my last. It's not leaking at all either.
I would LOVE to hear if anyone else is trying this. It's really made this mod top notch for me. Especially with the bigger hole. If anything changes, I'll update the forum.
Note: I just took off the cart to see if it looked like it's leaking even though I'm not noticing it. Looks very clean and it wasn't indented so I do think my atty wick is actually fitting inside it without pushing it down. Also, I find it much easier to put the little string/yarn I made inside the cart if it's wet. I just get it wet with e-juice and shape it in there. Make sure you line up the atty wick with the oblong whole that is made so it fits perfectly. Until I get my syringe to fill them with, I've been taking tweezers to remove the silicone top and poly-fil. It goes right back in with no problems.
