Revolver, the USPS has been under some serious strain lately, what with the government wanting to shut it down completely and all. We've already lost a very large portion of the postal service we had just last year. So if Dave sent it it's on its way, but if you're trying to track it you can just about forget about that as tracking anything right now is a 50/50 possibility that it'll work. You might even find that your package will magically appear in tracking a week after you've already received your package, it's happening more often than you'd think lately.

Not to stray ot, but someone at my post office told me that they just aren't hiring new people. So if someone quits or retires.... that's one less employee

Double post, but in case you missed it: Why Rhodium? The Facts.
 
Q: David, you’ve been making mechanical mods for over two years now, why did you switch from non-coated brass battery/switch/atomizer contacts to Rhodium Plated Brass Contacts?

A: Brass (as well as aluminum and copper) are highly conductive materials with a glaring detriment, they readily interact with oxygen on a molecular level, a process called oxidation (which is often referred to as tarnishing on brass). Most all non precious metals oxidize, even stainless steel, albeit very slowly compared to brass, aluminum, copper etc.


Q: What is wrong with oxidation?

A: When a metal experiences oxidation, a chemical transformation of the surface layer of the metal occurs, this chemically transformed layer severely impedes the flow of electricity.


Q. Can we see Oxidation?

A. Oxidation is virtually invisible because it occurs on a molecular level, it is only when it progresses so far that free radicals start breaking away do we actually see it’s effects. But it’s effects to the flow of electrical current begin immediately when these bare metals are exposed to oxygen.


Q. What If we don’t touch the brass after we polish it, will it still oxidize/tarnish?

A. Yes, it will begin oxidizing immediately after polishing, these metals only require oxygen to begin oxidation. Introduction of moisture by touching it or humid air will increase the oxidation rate.


Q. Can we slow the oxidation process?

A. Yes we can slow it, but not eliminate it, by applying anti oxidants to a cleaned surface. Anti-oxidants are petroleum based products (which go under many name brands, such a Dexoit Gold, Noalox, Di-Electric Grease, Vaseline etc) that, when applied to metal, form a protective semi-oxygen proof barrier. They are not conductive in and of themselves. They Promote conductivity by shielding the base metal from oxygen and the resulting oxidation.


Q. Ok, so I think I understand. Untreated bare metals experience oxidation. Oxidation interferes with the flow of electricity, which makes my switch fire inconsistently and lowers the voltage reaching the atomizer. But you still haven’t answered my question, Why Rhodium?

A. One of the biggest complaints users of all mechanical mods have is the frequent need to clean the electrical contacts in order to keep their unit firing. We’ve all experienced it; the dreaded push the button and nothing happens. Push harder or twist the button, try again. A few moments pause before our atomizer fires, followed by weak vapor. Arrg, time to clean again! Feedback on all mechanical mods is unequivocal, find a solution, so Super T set about researching a solution to the problem! Enter Rhodium.


Q. What is Rhodium?

A. - Rhodium is one of the rarest and most expensive Precious metals.

- It is a non oxidizing metal; oxygen and moisture have no effect on it. It will not oxidize, tarnish, or corrode.

- Rhodium is impervious to most acids.

- Rhodium is extremely hard, with over 4 times the hardness rating of gold, which is very important due to the high friction and pressure loads electrical contacts in a mechanical mod encounter.

-Rhodium is extremely resistant to electrical arcing. Electrical arcing occurs when electricity jumps the gap just before and after a switch makes contact and this electrical arcing creates hotspots that oxidize, but since Rhodium is virtually impervious to oxidation, electrical arcing has little to no effect on Rhodium, unlike Nickel, Brass and copper which are susceptible to the oxidizing effects of electrical arcing.

-Due to Rhodium’s extreme resistance to the effects of electrical arcing and it‘s extremely high melting point (3600+ degrees and a boiling point of 8000+ degrees), it is often used to coat the end of spark plugs which often see 20,000 volts and localized, intermittent temps in excess of 10,000 degrees!



Q. So the solution to eliminating oxidization was plating the brass contacts with Rhodium, I understand that, but What exactly does the Rhodium do (or not do) that makes my unit hit so consistently and so much harder then my other devices? Is it because it’s so conductive?

A. Actually, Rhodium is just an average conductor, it’s purpose is not to conduct per se, that is still the function of the brass base metal over which the Rhodium is applied and Brass is an excellent conductor. The Rhodium, poses virtually no resistance to the flow of electricity as resistance is also dependent on the thickness of the metal electricity has to flow through.

BUT what the Rhodium does do, is provide a virtually oxygen proof barrier over the Brass which prevents oxidation of the brass from occurring and since the Rhodium itself also never oxidizes, corrodes or tarnishes, it is always making the best possible electrical connection for the electricity to pass through. Hence, you see no loss in voltage to your atomizer and you experience reliable switch action, hit after hit and the biggest benefit of all, you never have to clean it!

The Precise was hogging all the attention. I wanted to see more of how the A2 and Precise got along because I know for a fact that the A2 and Precise, any Precise, get along better than most setups out there.


Hey Wing, when I get my upgraded parts for the P-18 will let you know how much better the Bulli hits on it. Will have pics tomorrow of P18 and Bulli A2

I am seriously teetering on the edge here. I've gone cuckoo for Precisey mods, but do I really have to have a new P+18650? Well it could do 3.7v, 5v, 6v and 7.4v. But, I think I'd have to reinforce the pockets in all my pants and shirts to carry it around out in the yard all day. Then again I have been looking for an excuse to upgrade my wardrobe, and the P+18650 could be just the incentive I need to do so.

I'd definitely like to get my hands on the P+18650 too :) Can't wait!!!!
Wing, let me know when you go wardrobe shopping, & I'll be your "stylist".

Ok, so I got this really sexy black leather triple cigar case in the mail yesterday. So, not only do I have my Pelican case to store "All Things Precise". I can use the black cigar case to hold whichever Precise i'm using at the moment, a tall 10ml bottle of juice & an extra battery if i'm using the P16, or 18350. This reminds me........pics or it didn't happen.

I'm sure (Ha!) I won't be needing an 18650, I have enough big things to lug around. But I'm absolutely certain an 18350 is in my future one way or another. Today I've been vaping the 18500 with a 306 all day long...this little thing is a beast.

My P+18,5 is on its way... !!!

I am curious, though, about one thing I have not heard anything about... The juice well...!!! Maybe it has been mentioned, but I was wondering whether it is very functional; meaning: Is its size the proper one?
I am asking because I was wondering if I should still use my Drip Shield with my Plus... !? I am not a 'messy dripper' actually, so wouldn't really need this if the juice well is the right size...
Any input on this would be appreciated !!!

Thanks!!!

=)

Funny, I was thinking about that the other day. Why no one mentions how well the juice well functions. It doesn't spit out, it's caught in the well due to the height placement with the atty in place. a shield has not been required to contain the residual. It's a really simple and efficient system, they stand above all other mods I own. Some of the other mods your hands get sticky from the excess fluid residue whereas my hands stay clean with the precise line. One of the nicest features in my opinion.
