Hey Scotty, got your H plugs yesterday and they are great. I've tried similar mods with holes and just couldn't get it right. They either leaked or dried out. This H seems to be good. I'm posting some of my findings though to maybe help people understand why it can be difficult to get this going right so they don't give up.
1. I have 2 types of 510 attys. I didn't realize it until I really looked. Some of my older ones are a little thicker on the steel wick from side to side. These don't seem to work well with this H plug mod, but they probably would work great for the holes (this explains my problems with my previous attempts)
2. The attys with the smaller wick work brilliantly with the H plug mods. I have three of them that I use for each flavor (I'm picky that way) and I'm having no problems with them on these attys.
3. You do have to get the straw cut just right. I cut mine where the plug
sits almost flush with the top of the cart (straw is just below the top). I do notice the plug bends in a little, but not much (not enough to leak) and I did eyeball the length of the straw. Now that I have the three carts made up, I don't have to mess with that anymore.
4. My really really thick VG juices (only one supplier) seem to not want to wick as fast as the others, but it makes sense because they take longer to spill out if you tip the cart upside down without the plug on top.
5. I've found that once I fill it and put it on the battery, if I tap it down (similar to an analog pack when you first get it) with the battery side down once or twice, it gets the
juice to touch the atty. Seems important to get the wicking started right. Once it's wet, it wants to keep sucking it up. If it's completely dry, I get some problems with getting it to start. Once it's starts ... look out.
This makes
vaping a great experience. If you like lots of flavor and smooth
vaping (like dripping) then you will love this once you get it going. I tried several of these myself and just couldn't get it right. Spent $10 with Scotty and never looked back.
