I call it ADP Mod.. Auto Drip Mod!

[TWISTED VICTOR]

I've tried the spring and it DOES work, but I'm doing it with a 401 and it's awful having to cut the spring SO small and try to get it in the tiny little cart. People who are doing this with 401s, please tell me exactly what you're doing to make it work without giving you a temper tantrum.

Try putting it in lenthwise, it'll need to be shortened, but the diameter should be ok.

looks nice, I might try that.
Thanks!

Just an FYI : Don't bother trying to use a little piece of fleece instead of polyfill (or whatever) as a plug with this mod.

I thought it might work because it has no strings, never unravels, and would be easy to rinse out. Yeah - I was wrong. It works at first, but then stubbornly holds on to the liquid instead of wicking it to the atty. Might work for PG users, but I'm strictly VG.

Yes... with the 401 I would try running the spring lengthwise.. like I am trying with my little Revolver (M702) carts.

I scored a bunch of stainless springs.... so I'm now less concerned about having them in there with my fluid.

Thread is tl;dr, so I don't know if its been mentioned.
I did this mod and its great. And what's awesome is you can hold the cart up to a light and check your "oil level".
Way cool.

Just the best!! Thanks for taking your time to do the video. Awesome! Working great on my 510...also have a Silver Bullet on the way and will try it with that as well. Can't wait for your next idea...Go go go

Kristin,

I think you hit the nail right on the head. Something like this could/should be the future of cartridges. The "membrane" top cap should either pop off (small sucker.. easy to lose) or be in a little hinge (molded plastic hinge). You pop it open, put in your 15+ drops, and snap it shut. No tweezers or voodoo required. The membrane top then comes in contact with the atty bridge when you put the cartridge on the PV.

The "spring mod" gets you the functional effect... the hinged membrane top just makes it a lot easier to use.

Kristin, that thing is a great idea. It could be just pop it in and go!

I took a drinking straw, snipped off a piece, then slit it up the side. It coils itself a little smaller so that it fits into a 901 cart with room left over.

I would not be using copper. Even copper cooking pots have to be galvanized on the inside.

I think those nylon springs sound good.

Ok so I'm using only 401 / EVO and then parts from China - passthrough more batteries atomizers, etc...
I thought I had found the perfect solution with PTB as it worked perfectly the first times but once washed and reused it acted like polifill...
Then I read about your post ! Amazing with a vertical spring and a little of FLuval on top for 401 ! THKS A LOT !!!!!

I am doing this with coffee straws, same results, what ever you use scotty is right! This is the BEST and last mod I will use on my 510 and 901 carts...... Beam me up Scotty!!
