The last piece of the wick I sent you . . . . and you sent back . . . . got vaped at .4Ω this weekend. I never told you, by the time it made it back here, some 2 weeks later (?), it was flat as a pancake.

It stayed flat? Kinda strange. Does still vape like normal?

Speaking of wicks... I still need to get your 7 strand installed in the RSST. Tomorrow perhaps. :)

Well, no, I rolled it around btwn thmb&4fngr and it revived. Oh, that old thing . . . . . . its probably stale by now. I just figured it worked like cr-p and you were too polite to mention it.

Nah... Just got several new toys all about the same time. Haven't touched the AGA or the RSST for awhile now. They both need a good cleaning. Both hanging around with month old juice in them.

Hey Jas nice switch, seems like a lot of work though. Over here the 2$ coin is about the size of three of your copper penies and is 97% copper rest nickel and ..... Can't remember what else.
Was thinking of a similar plan to you with that, but went with the drilled out $2 coin sanded/ground for a nice tight button fit on my second U-can mod, binds a little from time to time though and not sure I like looking at the queens head up the ... of my mod lol. Have a very cronkite pillar drill with shot bearings so the ability to get anything really level or parallel is crap hence the slight binding due to a slightly wonky shaft.
Did you just press fit the coins into the u-can sleeve plate or what?
And how does the button attach to the Aluminium shaft post? Press fit, silver solder or glue or animal magnetism, or did you thread it to receive the brass screw?

Brother, you ain't kidding. Abe's face is raised more than I'd thought. Trying to make pennies flat by grinding or sanding is a total pain in the .... Then, to top it off, as I was reflowing the solder, I moved the hot air gun and blew the pennies out of alignment. Thankfully I was able to nudge them back together with a pair of scissors before the solder resolidified.

Next one I'll start with 3/8" brass washers... No more pennies

Here are the steps I took after I had the pennies soldered into a stack...
1) Drilled and tapped a hole for a 4-40 screw in the center of the stack.
2) Cut the head off a 4-40 brass screw and threaded on a nut followed by the penny stack. (Used the nut to lock the stack into place on the screw.
3) Pressed into 80 grit sand paper until both sides were parallel.
4) Used a Dremel with a carbon cut-off disk to grind away the excess copper around the edges. Holding the Dremel perpendicular to the drill press actually worked faster and easier than expected
5) When milling, I created a very slight taper toward the bottom of the stack. As soon as the tapered end was able fit in the sleeve plate.
6) A hammer and a block of wood completed the task.

Short answer: yea, it's press fit.

As far as the binding... My larger press is horrible! I literally have to use the work piece to hold the bit and keep it from wobbling. Fortunately, I also have a small MicrLux press that is insanely accurate. (http://www.micromark.com/microlux-3-speed-mini-drill-press,7797.html)

Even still, I'm getting some binding if I press the button around the edges. I think it has more to do with the fact that I'm using dissimilar mete rials, both of which are soft metals, than design or workmanship. A thin layer of dielectric grease seems to have improved the binding without affecting conductivity. It will hopefully reduce oxidization of the copper and aluminum, as well... I hope...

And how does the button attach to the Aluminium shaft post? Press fit, silver solder or glue or animal magnetism, or did you thread it to receive the brass screw?
100% Press fit.

My original plan was to follow your design an lock it into place w a brass flat head screw but I didn't have any bits to match the taper of the screw head. You can see from the pics in my last post where I tried and failed.

Any way, drilling out the little sleeve in the button to 1/4" allowed a nice secure press fit with no need to secure from the back.

So I just received the novice from Chris creations and couldn't get it to fire for the life of me...the concept is exactly the same as the modded u can, only thinner and longer...to make a long story short, in the novice, you put the battery in upside down, ie with the + facing the bottom.
Same idea, an oring holding the battery up, and a screw the makes contact when you push the button. I think we can save a mm by doing that. :)

Ok as promissed I have made another U-Can hybrid, and here are a few terrible pictures taken with my I-phone, that do not do it justice at all, this thing is super tiny and very purdy :)
Original U-Can/RSST hybrid was 112mm from base of uncompressed button to top of drip tip, new more compact build is 96mm.
Juice capacity is just over 3.1ml
Details of build will follow if there is any interest.

A finger was harmed in the making of this mod :(

And yes, the airhole is a little larger than I'd have liked, but I have a plan :)

Personally I'm terrified of placing a battery in upside down. Any tear in the battery's shrink wrap will result in a dead short as soon as you press the button. With the battery pointed up, you'll always have the atomizer to act as a load/fuse.

Also, In the u-can, I don't see how placing the battery upside down will buy you anything in terms of space... In fact it would take up more space. You'd need to use a thicker o-ring at the bottom to add clearance for button throw. Placing the battery upright doesn't cost anything because there is plenty of head room above the battery nipple. The deck cap is catching the battery on the shoulder of the battery, not the nipple.

Sorry... Not not trying to be an ...... Just thinking out loud...

I'm loving the bottom button! Long live the Queen! (even if she has a hole in her head now. LOL)

YES, please, give the details of this build and provide some "under the hood" shots. I curious to see what you did with the tank.

Once again, beautiful work!
