REQUEST: 901 battery to LTv9 cartridge adaptor?

[BarryK]

I really don't understand this thread, there are at least 2 people (3 if you include me) who've offered to do the machining for you.

All have said 'send me the old batteries and I'll make the adapters' - but still non-one has come up with the goods and that old perrenial 'go, check 'em out at the hardware store' still keeps raising it's stupid, ugy head.

How many times do you need to be advised that all the e-cig threads are non-standard, I guess thats to discourage people from making there own.

The only way you are going to get the adapters you want is to supply parts, with the required threads, to one of those who have offered to do the job for you.

Give us the information and we'll do the job! (in my case, other projects permitting)

Sorry I just came across this thread. So you are saying the threads are different than any you would find at a hardware store? I would definitely say that’s to discourage you from making your own. So old parts or a machine shop would be the only options for making these. I plan on doing some moding myself here soon so I guess its old parts for R&D then a machine shop if I think there would be a demand for the stuff.

That's correct GL - see this thread: http://www.e-cigarette-forum.com/fo...25-open-source-e-cig-project-3.html#post57608

It's a long old thread but there is some useful information there.......

Great, Thanks!

Leaford was going to send me the parts, but I believe his computer had a meltdown. I haven't heard from him since, So I think he went another route.

Thanks to SuperSteph I Just picked up another little gem from here :

http://www.e-cigarette-forum.com/forum/modders-forum/8355-m401-402-battery-thread-size.html

So we now have the following:
801 = m9 x 0.75mm
401 = M7 x 0.5mm

It would be nice if we can collate all this information into a 'sticky' at the start of this forum............

I don't think they are non-standard threads , just typical chinese factory shoddy standard threads.
I've not pitched any but they just look like shoddy standard threads, and i can't see these far eastern factories paying out for specialist taps and tooling It doesnt make sense and it's bloody expensive.
I used to work in a metal components outfit for 12 years , mostly doing threads and welding so it is an educated guess :

P & B Metal Components Limited

anyways , I'll be making one of these adaptors for a member here in the next day or two , so I'll post pics up when it's all done.

haha , just found this ..my machines i used to work on...oh the memories

http://www.p-and-b.com/videos/vplayer.php?videofile=lowvolprocess.wmv

oh and thats a M6 x 1.0 rolled thread. Job no. 380.. man i still remember...and over 3 years ago too

 

[BarryK]

Of course they are non-standard threads, or should I say 'non preferred threads' - the Japanese have been using their own version of metric threads since the 50's, on cars, motor cycles and other products and now the Chinese are just following suit.

As for the statement "just typical chinese factory shoddy standard threads" that seems to be a very un-informed statement - sure the Chinese have exported some real rubbish in the past, as did the Japanese, the Indians, the Koreans, the Americans, the Brits and the rest of the European nations.

The difference is that the Brits and the Americans and Europeans could not compete on Price, with the result that, first the Japanese and then the others gradually came to dominate world manufacturing, the situation with China is different in that we have now sealed our own fate as far as our manufacturing industries are concerned, by supplying all our designs to Chinese companys and invited to them to "please make this at a fraction of the cost that we could make it for." but instead of passing those savings on to our consumers, all the extra profits went to the share holders.

The Chinese, not being a race to miss a trick, thought "We can do that too, and we won't have to pay the middle man his share....."

The result is that virtually all the manufacturing industries of the West, no longer exist and that 80% ( that's just a guess, could be anywhere between 50% and 90%, and growing all the time.) or so of all manufactrured goods that we, in the west, purchase are now made in China.

Precision consumer items like Watches, Cameras, Fishing reels, also Electronic components, household goods, electric motors - and a million other commonplace items now come from China - also Machine Tools for the hobbiest, (and those few western manufacturers that are still hanging on).

The British and American motorcycle industries are, apart from a few specialist, low volume outfits, dead and the US and Brit Car industries will be gone within the next 10 years or so

Bleak outlook? Yeah - got it in one..................

Barry

PS - I've been involved in the UK engineering industry for over 50 years and watched it all happen - for me, the rot started in about 1960, when the Japanese sent engineers with note-books and cameras to the Isle of Man TT races.

The following year Honda sent a team of 3 to compete in the lightweight class and won the team prize, within 5 years or so the Japanese owned the Motor Cycle world.....

Isn't hindsight a wonderful thing?

Great post Barry , i enjoyed the read.
One thing thow is these e-cigs arent high end consumer electronics from the likes of sony, samsung, philips or LG.

These are cheap cheap little devices, pound shop stuff really , which is why i guessed at shoddy standard threads.
I know chinese can make some great stuff on the cheap, even at P&B we had our own tooling dept but still used to get some of it made in China because it was cheaper and sometimes a better quality than allenvale tools would make for us.

2 ends of the spectrum here

I think we're gonna end up agreeing to disagree here, but........

I don't think that there is anything shoddy about the manufacturing methods used, and the problems that we have are really only with the technology - i.e. the batteries are just not up to the job they have to do, and the original atomisers were a joke - but, for the atomisers at least, things are getting steadily better. the later, lower resistance, higher amperage jobs are really so much better than anything you could buy 6 months ago, I'm still using the 1st of 2 that I bought a couple of months ago, the second has remained virtually unused. (that reminds me, I really must get a couple more, even they are not gonna last forever ..)

Biggest problem is the batteries, and will remain a problem as long as the manufacturers insist on making them look as much like real cigs as possible, when they finally get the message and abandon the 'analog' look and start to produce e-cigs that have manual switches and work properly, i.e. those that us DIYers are cobbling together, we won't need to be worried about thread diameters and pitches.

Cheers
Barry

PS - I just checked out the thread sizes on my pen styles once again and they are exactly 9mm x 0.75 - also checked the manual switch screw thread on my David Yang passthrough and it is apparently 7mm x 0.5mm........

............. I surmised in another post that the thread on my 801 is M10x1mm pitch - it's actually a very rare, extra fine metric pitch - M9 x 0.75mm pitch.

Now taps and dies for this size are rarer than Rocking Horse Poop - they are available, but at a ridiculous price, i.e. - around £50 for the die & £35 for the tap.

Barry

I just realised that a lot of panel mounting toggle switches, potentiometers etc, have M9 x 0.75mm threads.

I have also managed to get taps and dies in that size and at a much more sensible price from Tracey Tools, website here:
