building the ultimate bottom feeder

[turbocad6]

ha, probably just as soon as someone steals my idea and copies it and mass produces it

as I have said, I'm not developing this thing for resale or any commercial purposes on my end, I'm building it because I want it and it doesn't exist.

to me this concept is pretty simple and obvious, I'm surprised that there are not more innovations like this, I mean how many different expensive fancy engraved tubes do we really need? it seems that the industry is content on keep building the same thing over and over again, hundreds of different, yet basically the same simple tube mods, yet none that can actually close and not leak no matter how it is stored. if no one complains then the builders have no reason to change there way of building, is anyone actually asking for change? I know I am which is why I'm building this... of course stuff like the REO and the BB and all the other bottom feed mods are thinking outside the box too, well this is just my own thoughts on how it should be I guess

studiovap I did some math for you. I kind of just guessed that the max I can fit of 10mm piston with 5mm stroke would be way more than enough and I'd reduce to actual calculated values when I build the prototype. so I now did the actual calculations. the volume of the feed tube, assuming 1mm dia and 60mm long would be 188.5 cubic mm's of volume to completely fill it, the 10mm x 5mm stroke turns out that it would be waaay too much volume displaced, each pump would be over 1,000 cubic mm's of volume moved, so this of course needs to be reduced. as a better example: a 6mm piston with 2mm travel would displace 226.3 cubic mm's of volume, so this would probably be a better actual starting point, then it can be precisely calibrated to an exact desired volume via mechanically limiting the stroke with a set screw to adjust/fine tune and dial in the perfect feed. the fine tuning will also depend on the volume of the atty reservoir too but as you can see getting enough volume is not a problem at all. figuring this out is as easy as inputting your data here:

Calculating the Volume of a cylinder

theres an online calculator for everything it seems, so my "math" turned out to be pretty simple

Damn

I really want some sort of aluminum bottom feeder that incorporates a DNA20 chip and doesn't cost an arm and a leg. So far I've seen the Sunbox, but I really wouldn't pay close to $300 for it lol. As of now, my Billet Box keeps me happy, but I miss the old Reo days. Carto's have been more trouble than they're worth.

Can't wait to see the progression though. If you ever need a test dummy (or a product photographer) let me know

 

[turbocad6]

well when it comes to building a one off by hand mod then honestly the costs are very high, my mod will wind up costing me well over $500 for the first one if I consider my labor too, it's only when something is mass produced that the numbers come down significantly, for smaller production runs by an average mom & pop small business the price will always remain kind of on the high side, if they outsource it to china and order thousands of pieces at a time then the price comes way down, the opposite of this would be if I went to a machine shop and gave them my specs to build me one mod like what I'm building the price would wind up being over a grand for just the one mod.

 

[turbocad6]

just to correct my "math", instead of entering radius I entered diameter in haste, so the corrected volumes are actually 47.1 cubic mm in the fill tube and 56.6 cu mm for the 6mm X 2mm stroke piston... if my atty well is only 6mm wide and 3mm deep it would give me a total volume of 84.9 cu mm there so plenty of room for surge capacity

also interesting is that I was pretty conservative with my initial juice capacity estimate on this mod, knowing it will def be at least 3.5ml, well checking this calculator I can now see that my actual tank alone will hold almost 4.5 ml, so combined with pump capacity even if pretty small, makes this mod wind up being closer to 5 ml capacity, pretty cool for a mini mod like this I think. the reason my fluid capacity is so high is because my tank design has nothing at all running through the center of the tank which would steal volume.

 

[vapero]

I'm looking forward to seeing the pump prototype

 

[turbocad6]

I haven't given up on this pump design, just been busy playing with my new kayfuns, I also redesigned the body for my pump fed feeder a bit to build one to take an 18650 battery with metal tubes, also decided that I want a decent bottom feeder in the mean time so I built a Vmod to blind squonk like a reo, feeding an Igo L rba, gutted and rewired it and stuck a DNA20 in there, few shots for now, I'll get back to the pump in a bit and will put a thread up for it in the mods section, going to make it open source so no one can steal the idea and patent it claiming it to be there's, it'll be freely shared with the community, not sure how many others will also build one, hopefully others will develop on this pump design too as an open source project, it's def a step ahead of the current designs I think, recirculating immediate feed to the wick yet 100% sealed chamber when not being pumped

 

[Dunder Mifflin]

Spectacular!!! I crave to see more. Can you get the cover on the vmod? How did you retrofit the Igo l? Too many questions. I love it!!!

 

[vapero]

great to hear from you again! I tought you had made the Ultimate BF and went to hide in a cave!

 

[turbocad6]

HA, yeah, no cave yet, I wish

yeah of course the cover has to fit on the vmod and it will, still need to tweak the up & down buttons a bit for the battery to fit flush but right now without the battery the cover fits, and the stock sized squeeze bottle fits, I tried to do a larger bottle but I think that's just pushing it I will def get it to fit the 18650 too. the Igo L was just a matter of drilling up the center of the pin until deck height then drilling through the side of the pin for the feed to reach the deck... it works really good, now I see what all the rave is of the reo, I modded this one to feed like the reo, blind squonking and eliminated the upper juice chamber thingy that the vmod has, I wouldn't call this the ultimate but it is pretty good, much better than the Vmod was stock. I almost bought a reo several times but I just can't bring myself too do it,so I did this Vmod instead for now

I just put up a thread for the modded Vmod here:

Hey, thanks for that. Looks interesting!

 

[turbocad6]

another update, I still haven't given up on building my pump design but I wanted to build something to use in the meantime and I winded up wasting some time building the Vmod only for it to fail, so I then ordered a reo to have something to just use immediately, and then I just couldn't help myself so I winded up modding the damn reo too stuck a dna20 in it and man, I gotta say that I'm really now loving my reo, I shoulda got one long ago. it's doing the job great for me and now I almost don't even care how long it takes me to build my pump feeder I will build it eventually though, probably over the winter months

here's a few shots of the reo I modified, and I put up a thread for it here : http://www.e-cigarette-forum.com/forum/reos-mods/478411-moddified-reo-grand-dna20d.html



here's some pic's if you don't want to bother going to see that whole thread:

 

[Ryedan]

That looks absolutely great turbocad! Very nice clean work. Going to have to check out the thread.

 

[Pierces32]

Hey turbocad, I've been admiring your work, both here and in the VMod thread. It inspired me to create this modded VMod. My first attempt at modding and rba's. It vapes quite well. My initial quest was for more flavor which brought me into the rba threads (cotton wicks) and bottom feeders, where I came across your brilliant dna mod. Just thought I'd drop by to say thanks for the inspiration.

 

[turbocad6]

hey man, that looks great, love inspiring others to get in there and customize and build stuff I keep building new things but still haven't really buckled down and started really developing and building this pump idea that I have, hopefully soon I'll have some time to play

 

[Pierces32]

It's hard to hold an accomplished tinkerer like yourself down, keep on keeping on!

Pierces, How much bigger is your mod over the original? I really like the way that looks but I know I can't make one like it. I just don't have the proper tools to tackle something like that. I've got an idea for using the body and battery of a Groove, some parts from Bogger Box and making my own bottom feeder. But then again, I know I don't have the proper equipment to tackle it just yet.

 

[jcalis1394]

You guys are awesome, keep on the modding! That wooden VMod looks stunning, and that DNA20 REO is epic. I've heard rumors of the DNA30 *might* allow for 30 watts regulated output, so keep at it turbocad! Your ideas are amazing, don't give up on it. If you manage to pull something like that I'd throw cash at the screen expecting you to catch it .

 

[Pierces32]

BD, it's not much bigger than a pack of stinkies, 100's. The height may be 1/4 inch taller, the main size difference is the thickness of the wood. It's still pocket friendly though. Been using at my work all week, though I still go outside to vape, don't like getting in peoples faces etc. The only power tool I used was a dremel & a square random orbit sander, two clamps to glue the initial box together. The sqwoonk hole & top were cut with a hand scroll saw, the kind used to do back miter cuts on molding. You can pick one up cheap at Harbor Freight, Lowes, HD etc. If you aren't sure what one looks like i'll be glad to post a pic.
I also made a 2.0 version, just haven't had the time to put the finishing touches on it and I have to work.

Speaking of patenting things... If anyone tries to patent something that's already in the "prior art" (i.e. in public knowledge or use) even if they do get the patent, you can show that you came up with it first by showing this thread and the date... You won't be able to get a patent but you can invalidate theirs. Anything that's publicly disclosed like this can be patented within one year by the inventor. After that it's considered public knowledge and is unpatentable.
