Looking to build a bottom feeder

[bjseggerman]

I want to try my hand at a bottom feeder. Just a few ?'s

Do the fat daddy vapes 510's have a hole in the middle so liquid can run through? Are all 510's able to do this or do I need a special one?

And I am not sure where to find those "nipples" to connect the tubing to the 510. What are those called? I use "nipples" for lack of a better term.

I think I will wire a switch into it because I'm not quite ready to figure out a fully mech version. How do I pick a switch? Ratings? and such. I'm a noob.

I plan on using an 18650.

Thanks for your guidance!

I'm also prepping to build a bottom fed box mod with a sx350 chip. The feed tube setup is by far the most daunting part of the build for me. I have decided to go with this connector from Fatdaddy vapes. It will require modding, but it will be a sturdy connection when finished. What I'm most concerned about is drilling out a screw to use in place of the center pin. I've been looking at those Russian 91% adjustable center pins If that would fit it is already hollow.

I wouldn't have thought the Fatdaddy V3 would be any good for bottom feeders. You mean the spring loaded ones right ?
Not saying you couldn't mod one to work but it would take a bit of work to do so.

I haven't done one yet but the video shows a guy taking one apart . It looks like it would be easy to leave out the adjustable center and spring assembly. Then replace it with a hollow bolt to use as a feed tube.

The switch will need to have the appropriate amp rating for the type of vaping you intend to do. A one ohm coil at 4.2 volts will require at minimum a 5 amp switch.

I was just thinking that if you could make a new longer center pin (hollow) then it would be possible to leave the spring and have the best of both worlds.

 

[JimzDogz]

That looks like what was used here. This will be my first build so I'm borrowing as much as possible from other mod builders.

I was also thinking of just getting the sub ohm upgrade kit from Reos Mods and using that. Its $25. It would come with those needed nipples and then get the 510 from Fatdaddy vapes. Wondering if I can get all those parts for cheaper though and so its more custom and not just a reo ripoff

Maybe, but I won't know till I have one in my hands.

That is one way to go. But, $25,00 for $3.00 worth of hardware is a little steep.

adattatore Flatter

This would be a easy way to do it. But 24,90 euro is also steep. Not to mention it would take a while to get from Italy. Wow, with shipping it's 35 euros.

scrap the idea I had earlier, just realised it wouldn't be sealed properly..

 

[JimzDogz]

I've had so many of my ideas lead to dead ends, that I've lost count. lol

 

[Lentulusbatiatus]

could still be done with a small o-ring but a lot of messing around.. lol

One option is to use a regular 510 connector like this 510 Battery Connector, Gold, Large Hole They are brass so the threading tends to strip out after awhile. You could solder a small diameter brass tube inside the hole and attach some plastic tube to the brass tube. If you do that, make sure you use lead-free solder and lead free brass or you will slowly poison yourself.

i too have been contemplating building a bottom feeder. it appears fdv has released bottom feeding pins. its the third item on the drop down menu. call me dense but im still not quite sure how these work out...where do you solder on them,which end is up, and what size tubing. guess i need to do a bit more research, and gather some more motivation to do another build

 

[JimzDogz]

I wish that I could speak Italian. This video is as close to what I'm trying to build as I have found. It is roughly the size as a Reo Grand VV mod. This has an sx 220 chipset. I'm going with the sx350 chipset. Very nice job, well done.

I just ordered a set. I'll let you know how they work, as soon as they arrive.

I don't like the idea of brass pins for a bottom feeder myself, SS would be better.

Generally speaking I agree. But, brass fittings are routinely used for water line compression fittings. I'm not sure these are brass they could be copper.
