Titanium wire, vaping and safety

[druckle]

It cuts double wire too

Really weird. It was a non issue last week...

Wow! I don't understand that one. Titanium is a lot stronger/stiffer than Ni 200 and I can't imagine how that occurs. You must have some guillotine screws in that thing. Maybe a little piece of steel wire beside the titanium wire?

You haven't stared anabolic steriods in the last week have you?

I have no idea what's going on. My titanium is way harder than kanthal and even more then nickel. Like I said, last week I did two builds without hassle. I tightened down the screws and the wire got stiff like a piano wire. Completely solid. Yesterday I was I wasn't even cranking down that hard when 'snip' and the wire is cut in two

I know this is totally off the wall.....but...is there even the slightest chance that you grabbed the wrong spool of wire when you made that coil?

 

[TheotherSteveS]

Tony did you try a kanthal build in there??

Tony,

Is there any chance that the wire is getting push to the side of post hole and when you tighten the screws the wire is getting caught up in the threads. When you were doing the single coil the single wire tends to sit at the bottom of the post hole but with two wires in the hole at least one will get pushed to the side and caught between the screw threads and the threads in the post.

I have had that happen with Kanthal and once the wire gets to the side of the screw and drawn up into the threads it will never feel like it is getting tight but the threads are acting as pair of scissors and up until the time the wire cuts it will feel loose.

This may not be what you are experiencing I am just throwing out things that I know will cut wire hoping something will turn on a light bulb on your end.

No intent to be patronizing. All I know for sure is when dual coiling it is hard as he!! to watch everything, hold the wires, turn the screwdriver, rub your head and pat your belly all at the same time. We won't even mention a civil conversation with the wife and keeping half an eye on the kids.

PS - rounding the end of the screws can make the scissor effect even worse with small wire.

Tony, had a similar problem some time ago: abruptly one post screw started to cut thru Kanthal wire like butter. In the end it was a shard of steel from the screw that landed and seated at the bottom of the post screw hole. Fixed it by drilling the bottom of the post screw hole with a small Dremel burr.
And yes, chamfering the screw initially made the problem worse [emoji4]

It's a mutation x! I have a v3 and I have had the devil of a time getting a dual build in it for the same reason. Having seen Georges suggestion I think that wire creeping up the side into the thread could well be the problem. Certainly sounds like what was happening to me....try screwing down as far as possible leaving just enough room to get the wires through...

 

[tchavei]

Thx for all suggestions guys.

I'll try again tonight. If all fails, I'll go and get some crimps.

Yes, it cuts it clean off... I have guillotines instead of deck posts [emoji14]

I think it used to hold well when the wire jammed between the threads and the wall. Now it seems like it starts bending upwards and snip, it's off.

Man that is ugly. Mine was bad but not that bad To be honest, you might get away with tightening down until it starts to bend up and then just leave it at that. Probbs would work for kanthal but maybe not for Ni/Ti

Hope you sort it out!!!

 

[tchavei]

Oh, I have to. This is my "new build experimental" atty so it's the one where I try new coil designs etc. After lunch I'm going to a jewelry diy store see if they have the crimps. If not, I'll go to the fishing store. As long as they aren't lead based, the crimps should be ok to use

Ok

Managed to get ahold of some sort of crimps (rather silver tubes) and it works. No problem whatsoever holding the coils. I won't mention building them and crimping the ends because that's another completely different story lol.

Anyway, learned a new thing about my titanium wire... Don't dry burn it for extensive amounts of time because it will become grey. Seems that Torching is fine but dry burning at 20w isn't a great idea. I had to do it though to make sure both coils would fire the same and from the inside out. One of them wasn't so I had to fire a few more times and mess with the coil so maybe it was too much.

They are working great now and I'm still alive

You can see partially the crimps stuck in the picture

How are your Ti coils?

Oh - did I forget to mention that putting the crimps on and then getting them in the post holes is a real PITA - Oops.

PS - the good jewelry crimps are made from tubing that way you don't have to deal with seams in the crimp.

I expect that the reason you were getting more voluminous oxide when dry burning for an extended period of time was caused by the availability of oxygen being higher during the dry burn than it was in the torch flame. In a flame the oxygen content can vary greatly depending on the location of the wire. The flame can vary from oxidizing to reducing depending on the local availability of fuel and oxygen. That's why I always do a dry burn in the dark and try to pulse the current to avoid a glow for any length of time. I'm not really much concerned about the titanium oxide present being a health hazard in vaping but the loss of metallic titanium changes the resistance and titanium also absorbs oxygen quickly at higher temperatures which causes it to become brittle.

Tony,

Are you using TC with those Coils? Compressed Coils on titanium? I had heard touching compressed Coils for TC is a no no.???

Looking good man. If you remember I saw the same thing with a dry burn although I really beat on it! Anyway I think it's clear we are good to go with this stuff which is cool.

To paraphrase
Nickel is dead, titanium is the future and the future is now!

Sorry Rip!!

Druckle,

Tony said you knew a lot about Ti but you even thought of stuff (that makes sense) that I would have never even give a thought to i.e. Torch flame consuming the oxygen so not available to oxidize the Ti vs Dry burn which has all 20% Oxygen available to oxidize the metal. Gee this is "no country for old men" (I think that is the name of a movie)

At the edge of the flame there is plenty of o2 although not as hot. I really think torching or significant dry burning is dodgy at best!

Steve,

I sure as heck ain't going to disagree with you and Druckle. I know when I am out of my element.

I am just waiting to see how Tony's touching Ti coils work out.

Hey George. I don't know much really but I know this stuff will oxidize badly if you beat on it!!

Definitely props to Tony for the duals!! Way to go mate. I still have to follow through on my promise to try a sleeper. I'll have a go tomorrow on my vertex which should be ideal!!
