Warning: If your feeding tube is metal.. and it goes through the center of the battery connector.. then it will be the positive (+) pole of the battery. If you poke through the bottom of the atty far enough the tube will contact the metal mesh on the bottom of the coil pot. That metal mesh is grounded (-). Bad things can and will happen.
Trust me. I know this to be a fact! 8-o

How would one go about feeding from the bottom? Or is that best left to the professionals? My next mod WILL be a juice feeder of some sort, I just have to determine how and where to feed. Any ideas/suggestions on what a no-skilled-hack like me can hobble together?
Appreciate everyone's thoughts!

Yes, good catch Scottbee.
If you actually touch the nickel foam with your feed tube, you will no longer need the heating coil, 'cause you can just vape off of the resulting sparks (for about 2 seconds
)
The only way around this would be to use a non-conductive feed tube (that won't melt) if you can find such an animal. I'll have to ponder that one.

You can use thin-wall Teflon tubing. Readily available from places like McMaster-Carr. It has excellent thermal resistance, electrical resistance, can handle high temperatures, and is generally "food grade".
Yes it does. And one side hole vent.
And I believe Teflon has toxic liabilities when heated to extremes - did Dupont receive criticism for using it on pans and Dupont factory workers suffered health issues from exposure? Don't have time right now to Wiki that temp range, so it might still work.
There are high temp silicones available - still waiting for factory samples for a cart mod and atty core insulation test I am running
Yes, Teflon can release toxic fumes when heated to high temperatures. The exact transition temperature is in debate.. but it is generally believed to be above 500 degrees F. WAY, WAY, WAY beyond the temps that you will see at the base of the coil pot.
Yes, the temp needed to put of toxic fumes is above 500 degrees F.
I make teflon parts, so am well aware of the "teflon flu" and the temps needed for it to become toxic.
I however, have NO idea what the temp is as the base of the coil pot.
I DO know (found out the hard way), that analogs WILL heat high enough to give you the "teflon flu" should you happen to get any amount of the teflon material/dust/etc on it.
The tubing I have is high heat silicone but I was going to use a short piece of brass pipe through the batt connector up into the atty. So the consensus is that I should abandon this idea and just go with the more standard cart feed? Design wise, I'd really like to come up from the bottom but I can re-route stuff to top feed if that's the best way.
So, you're thinking of choosing a design where the bottle feeds a cart/carto like the mrpuffer?

Personally I think the bottom feed is the 'step forward' in the whole juice delivery system. The cart feed systems are going to be easier to do, but I would think the flooding would be a major PITA with that method.
With any kind of pump it's going to take a while to perfect the technique of pumping, and using top feed, every time you flood it, you have to tear it down and blow it out.
With the bottom feed, the pump is going to soak the nickel foam/wicking and then suck all the extra back. Even if the bottle is pressed too hard and you fill the atty half full of juice, it's all going to come back down on the pump release. Seems like, it would almost be impossible to flood with a (sealed) bottom feeder. The key is the 'sealed' part though. If there is an air intake below the atty (like the JB), then the negative pressure of the released bottle is sucking back air instead of juice.
Just my .02

I'd like to bottom feed for the reasons Highping listed as well as for ergonomic/design reasons. I've got the rough design laid out (in AutoCAD) both ways, with the feed line coming in above the atty & one where it comes in below.
I'd like to start fabrication sometime next week but I need to decide which way to go since the 2 designs are not completely compatible (bottle space and access as well as atty location is different). From a per design perspective, I'd prefer coming up from the bottom, it shaves ~3/8" off the height of my "case" and it'll be slightly more user friendly.
Since I'm going to hand fabricate the "case" (and I'm notoriously picky) I don't want to spend 20+ hours fabricating something that I later find out just won't work.
Looking for a consensus on invention is a sure way to do it the way it was done before. Let your mind wander.
While I agree, I'm more interested in making something that works, than something groundbreaking!
Since I've only built 1-1/2 mods I don't have the knowledge, experience, skills or talent to do cutting-edge stuff. I leave that to others, I know my limitations (at least I thought I did, now I'm not so sure...)

But considering that every atty has air intakes below the bottom, wouldn't that imply that it is a prerequisite for an atty to work? Has anyone tried sealing up the bottom intakes to see otherwise?
All of the air that you inhale comes through those bottom two holes (510). If you block them off, you simply won't get any air or vapor unless you provide some other pathway for the air to enter the atty.
The center bottom hole can also be an air pathway, but it is plugged by most battery configurations.
