Printed DNA30 Bottom Feeder

[BobC]

First, I have say THANK YOU to gdeal. This is a great mod!

Cocky me, when I first saw it I thought it would be a piece of cake, after all I have built a bunch of mods! I have to admit, this one was a wee bit more challenging than I expected. Soldering that Alps switch, lots of tight work, etc.

Hits good, and maybe this is normal, but I fear I may have done the tubing wrong, I followed the photo walk-thru gdeal did, or tried to anyway. My problem is that it seems to be real slow filling and sucking the excess back. I even took the atty off (to eliminate the Cyclone) and just squeezed some up into the 510, a very slow ooze at best, and I was pressing the hell out of the bottle.

Any suggestions?

Mike, are you using the bottles in the parts kit or the 9ml Vapage bottles?

In either case, the tube should not be constricted at all by the cap, it should be tight, but not collapse the tube in any way
The 9 ml bottle is a bit tougher, just use the cap, not the mini cover that comes with it

Good point.....if you have a tight cap seal you dont need the dripper tip to snap into the bottle. Another method which works well, is to leave that snap mechanism in place and not use the cap at all. Rossum turned me on to it. Its not as secure, but it holds well and is much quicker for refills/change outs. You can see the threads from the screw, going threw the tube and seating well in the dripper tip.

Thats how I've been running for months, no leakage at all.

As of the other day, I've started using the Vapage 9ml bottles, They're a better fit and actually hold more
I use the cap, not the cover that comes with it, and used a 1/8th drill bit to start the hole, then used a round file to fit it

 

[Rossum]

A good point. It depends on how much of the tip you cut off of the drip tip part. We want a tight compression fit on the tube, but its possible that the tube (and the 1/16 hole) can get compressed by the drip tip if its too tight. If you dont take enough off, the drip tip wont stretch and it will compress the tube just below the screw. If you take too much off, then you risk loosing the leak sealing compression. So its a balance between hole size drilled and where you cut the tip. If you have the tube extend about 2-3mm out of the bottle tip, there should be enough screw threads that can make its way past the all of the compression points.

I don't drill the dropper cap, I just slice the tip off off with a sharp knife.

The ones from the V3.1 parts list, same as was in the co-op. The extra 1/64 th in hole diameter did the trick the trick for me.

George, I can see that Peko is not gettin any love (way too clean) send it my way, I'll get it dirty

Hide your Dibs folks, we have a new squonk convert among us

What is a cap and what is a cover?

The Vapage kit comes like this:


Don't use the clear cover, drill the white cap

Are the Vapage bottles softer than those provided in the parts co-op?

Just a touch

Thanks just bought a total of 8 bottles . What's the reason for not using the transparent cover?

 

[mikepetro]

You are welcome! I gotta say, I was getting a bit worried there that you gave up.... Very nice job on the wiring...your close-up pictures make it seem like a walk in the park. Did you glue the two alps wires together?

100ml is about what I need to calm shaky hands after soldering one these up

Naw, co-ops, fish tanks, shrimp tanks, and RL got in the way for a while.

I used ribbon cable on the Alps, the conductors stay together nice and pretty, and in this case made soldering easier. That blob in the middle of the two wires is actually some of the clear jacket that holds the ribbon together, it does look like a glue glob though in this light.

Of course taping the wire to a ceramic plate, and then taping the Alps to the plate to line it all up and hold it still helped a bunch too.

Not stiff enough to stay on proper and prevent leaking

Have you ever filled a bottle a bit too much? Using SS tube into the bottle allows a juice refill to the top.

An easy SS feeder tube that eliminates the constricted tube at the bottle cap seal and lets you fill it right on up.

The cap first drilled from inside the flange with a bit that fits provides a good center for drilling it centered with an 11/64 bit. A short chunk of typical feeder tube inserted and thread it onto the vented screw as normal. Finish by tapping a section of SS tube through until it touches the screw.

A very full bottle doesn't leak out the top due to the displacement of the thick tyvek tubing. It also keeps the path unrestricted so VG squonks easy in the cold. Also, just feeding the thick tubing into the narrow neck of the vapage 9ml bottles can get messy as the neck scrapes off juice when mounting the bottle.

Still has a bit of flex for easy handling during refills

It's easy to do and I think it works better It certainly make the coffee taste better!

Looks like a lot of work for .02 ml to me, with the tube, you just suck on the drip tip, covering the atty hole to draw the juice up to the tube, no loss

I'm sorry, it wasn't my intention for somebody think that the .02ml extra capacity, or whatever it is, was actually part of the point ... ?
Never overfilled causing juice out the top when the feeder tube is inserted? Squeeze cold VG through a restriction? Have you ever used the vapage bottles?
I see it as not much build effort to save considerably more cleanup effort later (or worse liquid on the DNA screen). I use SS feeder tubes with the 6ml bottles too for an easier squeeze, not for increased capacity reasons.

You sure convinced ME! Where do you get the SS tubes? Good info!

 

[TyCreek]

Last year I got several sizes from amazon and the one linked above is what I used for my last couple rigged up like this for the 9ml bottles. The 6ml bottles don't have that little flange in the cap to preserve (for helping a bit with sealing) so I use a bit larger SS tubing.

DOH! Sorry didn't see the link in your original post!@
So the original link is for the bottles from Vapage then right? Those are the one I got.
