I think my Reo died.

[zmauls]

I've never experienced this kind of problem with any other mod.

It simply does not fire.

I've tried all four of my batteries (fully charged), and the same thing happens every time. It will hit half-decent for about 2 or 3 puffs, then, with the door off, I see sparks where the connector meets the battery and then it just dies.

Considering all the batteries work fine with other mods, I have to assume it's the Reo.

I have taken it apart completely and cleaned all the connectors. The problem still persists.

What is the deal here? This is horribly frustrating.

Use a file on the firing pin, then apply some noalox to it, & give it another go

This exact thing happened to me. Had a lot of arcing/sparking at the positive connection, so I sent it back to Rob to take a look at it, but in retrospect, I probably could've just fixed it on my own. As FEEDER said, take a nail file to the firing pin and really put some elbow grease into it. Make sure the file is making good contact with the tip of the firing pin, the point that touches the battery, because that's where oxidation builds up. I personally use a jeweler's file because it can really fit in there. You can get one at a crafts store, like Michael's if they have one in your area. Then apply noalox to delay the build up of oxidation.

Rob is currently in the process of getting new positive contacts manufactured that will help with this oxidation issue. I've been checking website daily for updates.

If that sparking is particularly bad, it will melt you delrin firing pin. I have gone thru about 6 of them. Some people will also polish the top of their batteries and noalox that too for good measure. Anything that helps reduce oxidisation and maintain a good contact.

Is arcing when you release your button also caused by a dirty positive pin? I just noticed I melted one of my buttons last night. I'm pretty sure the contact is as clean as it can be since I've filed it to the point of shininess. I installed a new switch and after a few puffs I checked again and found melting has started again.

It only seems to arc when I release the button.

I'm running a 0.8 micro coil on an RM2.

Thanks!

What batteries are you using ? It really does sound like a dirty contact. Do your batteries have a flat top or a button top ?

 

[supertrunker]

Noalox the pin. I modify my pins to stop them melting.

It will not stop arcing if your mod is dirty. Clean it and noalox it. This is not recommended and i have had people telling me it'll short the mod etc - so i'll post it anyway!

one rivet: left to right - take inner out - ceramic paint(waste of time) - mount on firing pin. I used epoxy to glue it.


I should add that your best long term solution would be a PTFE/teflon firing pin, since it has a higher melting point.

You contact is dirty you need to clean it good and apply some pressure when filing the contact

 

[Treebeard]

I'm usually between .6 and .8Ω on my coils and have never melted a button. I file my firing pins about once a month and apply a tiny bit of Noalox. Are you using a button cover? Are you sure that the firing pin is making solid contact with the battery top? Sometimes a button cover doesn't allow enough travel to fully reach the battery and make solid contact. Are you using flat top batteries? These mods are dead simple and it sounds like a contact issue whether at the battery contact or the 510 (unlikely). Is your atty making solid contact with the 510 center pin?

I'm using an AW. I've filed both the battery's positive contact and the Reo's firing pin. I've filed the firing pin enough to lose the pointy tip (it's now like a \_/ ). Arcing only happens when I release the button, Is this good enough?

Apply a bit of Noalox and you're set.

Hey Z once you get it filed and nice and clean. Put the Noalox on the button of the battery not the firing pin. A little bump of Noalox on the battery button causes the firing pin to be submerged in the Noalox and there will be no arcing because the pin is surrounded by the Noalox. Therefore it can not arc for lack of oxygen. That's my theory and has worked for a couple of months so far. It only takes a little while for the pin to become oxidized I think I've passed that point where it should have stopped by now.


BTW Reos don't die......it's usually user error. We've got your back.

Yeah, one of mine is not pointy anymore either. Whenever I notice a little sparking I just give the pin a light filing and use a soft polishing wheel on my dremel and some compound and polish the battery tops till they are super shiny and free of any dark spots created by the arcing. I apply a very tiny bit of Noalox to the pin and the battery top and it takes care of any arcing for a long while.

General question(confusion): Trying to wrap my mind around the melting button thing.

Where is the heat coming from. Does the button melt all at once or over time? What makes a firing pin so hot that it melts the button (surely it can't be a little bit of arcing. I've had some arching and it never melted anything). How does the heat get transferred to the delrin button. Is it because oxidation on the pin prevents current from traveling the span across the firing pin to the 510 center pin. Is it the battery that gets hot (surely not at .8Ω).

 

[supertrunker]

I think that bit of arcing has plenty enough power to heat a firing pin (22W with a 0.8Ω coil and new battery) and delrin melts fairly easily in my experience. Quite often i have seen the firing button melt with the shape of the firing pin in it - such that it will no longer lock - and that suggests that the tip of the pin is getting very hot, very fast.

Yep throw a dab of noalox on and you should be good. I suggest getting a finer file no need to take so much metal off I file my reis every week or so and still have a pointy tip happening here

 

[SeaNap]

FYI arcing will only ever happen when releasing the button (opening the circuit). I work with 6.6kV and we actually have to use disconnect contacts that are vacuum sealed to prevent arcing, but even they eventually wear out over time because of arcing.

Thanks! My problem is sourcing Noalox locally. None of the hardware stores I've visited even has a clue what Noalox is so I had to make do with a contact cleaner that left an anti-oxidant layer.

They have it but don't even ask them about it. They just look at you like you have two heads. It is almost always found hanging near the multimeter rack (HD & Lowes). I found some just the other day. I asked the attendant where the multimeters are and he brought me there and said "which one do you want". I said "this one" as I reached for a 4oz squeeze bottle of Noalox. I left him with a puzzled look on his face.

 

[supertrunker]

i bought mine from Amazon after eliciting exactly the same response from the store staff.
