Possible solution for connecting 510 atomisers

[kinabaloo]

Helicoils !

Strong Stainless steel. About $15 for 20.

All: eBay Store ? TOOLSQWiK: Search results for.

M7: http://cgi.ebay.com/20-Helicoil-M7-...id=p4634.c0.m14.l1262&_trkparms=|293:1|294:30

The M7 is 10.5mm long; certainly long enough, could be shortened.

Just need to put in a round piece or board or plastic at the bottom with a positive contact point (as on torch heads - the board with a contact point for the positive terminal of the battery).

Then perhaps hot glue as required.

ps: Didn't find M7 0.5 yet (assuming that's correct), but seems to me that an M7 1.0 would work. Within minutes would have a strong threaded connector with electrical connections and air flow.

(The helicoil would be used the other way up)

The hot end of a 501 atomizer:

VERY interesting idea!!!

VERY interesting idea!!!

Thanks man !

i also came acroos those while searching for a M7x.5 tap, but .75 was the smallest i could find. wouldn't the 1.0 be prone to cross threading?

I was expecting that it would take two atty threads at once, as an exact multple (2x). Worth checking out.

Perhaps it is 0.75. The 901 threads look about that and I can't imagint that the 510 would have closer threading.

Previously I suggested using some stiff wire (toaster style nichrome seems good for this) to carefully wrap around the threads of the atty and then use some glue or solder to hold in place (then unsrew atty).

Someone may have an M7 1.0 in their toolbox/attic and be able to say aye or nay ...

i tried something similar to that long time ago (as an expansion adaptor), but not much success, i was just using multistrand copper.

thought ~ you should run this by dedmon....

...I'm using 18 gauge copper wire and bending it into a v or w shape. Then wrap it with putty. Problem is, getting the atty to stay. Although copper wiring is softer than the brass, I'm finding it hard to want to twist grooves into the wiring to make it hold.

... he could wrap the atty, then mold to it, shape, whatever.

Multi-strand wouldnt be suitable. I have tried on a 901 with some nichrome (toaster guage) and it's not bad but a bit thicker and it would probably work. The cross-section is round rather than square, but would still be ok.

Here is my secret source for metric taps and dies:

Amazon.com: 7mm x .5 High Speed Steel Plug Tap: Victor Machinery Exchange

They ship fast, shipping seems kind of high, but they have stuff that you can't find anywhere else. Search thier store front. They have 7x1.25, 7x1.0, 7x.75....

Yes, that's the obvious way to go but only if one has a lathe.

By eye, I'd say the thread pitch is either 1 or 0.75; but most say 0.5

I'll put my 2 cents on 0.75.

When i say 'by eye', i'm looking at a pic on the screen and doing some trig

btw, if the 1.0 helio thread is too wide, just put it in a press, or (enter improvised technigue here) ...

if a 901 is M8x.75, then doing a side by side i'd have to say the 510 would be .5, much finer thread (smaller pitch).
.... a 510 atty thread against the side of a 901 batt thread and you'll see what i mean.

lathe? nah. only if you're going to turn your own stock.

@Laredo7mm
thanks for the link! even if shipping is killer, it's got to beat the one i was looking into!

a lathe is needed for a die, no ??

guess i lost 2 cents

With a magnifier I'd put a 901 at 0.85 so might be 0.75, might be 1.0

 

[kinabaloo]

Oops, too much wine!

I am sure now: 901 is 0.75

ps: the forum is approaching 1/2 million posts!

As of now, 417,061 posts.

And 0.5% are by some guy called kinabaloo
I really need to cut back; I only joined in march - eek!

 

[CanyonRunner]

Don't forget to order the drill bit if you need one, 15/64 should work.

Nah, I use dies and taps by hand, no lathe in my shop, unfortunately.

I made up six feet of 8mm x 0.75 in about a minute a while back. Put the die in a vise, chucked up some correctly sized brass tubing in the hand drill, and drove it though the die. Worked great, just make sure you use plenty of lubrication or cutting fluid, it gets hot!

The pic is of a M12 x 1.25 so much for your eye

 

[kardjunkie]

so dowes the 510 atty screw into the 7X.50 taps that were linked here?

More likely the trigonometry let me down

no the atty would screw into a die. The tap would screw into the battery.

510 high speed steel (Bottoming)hand tap 7mm x .5 ( bottoming tap is for threading down to the bottom of a blind hole just like an atty connector Amazon.com: 7 MM x .5 High Speed Steel Bottoming Tap: Victor Machinery Exchange

510 high speed steel round Die 7mm x .5 Amazon.com: 7 MM x .5 High Speed Steel Bottoming Tap: Victor Machinery Exchange
The 7mm x .5 die is great for making a threaded pulling bar for ripping out the 510 battery connectors Vapers Forum - View Single Post - Ripping apart a battery


all three pieces are available for $18.30 + shipping



They also have taps and dies for the 901 and 801

801- M9 x .75
Die: for threading battery connector threads
Tap: for threading a connector pull bar

901- M8 x .75
Die: for threading battery connector threads
Tap: for threading a connector pull bar

401- M7 x .5
Same as the 510

I have personally used all of the above and can guarantee that they are the correct tap and die sizes

no the atty would screw into a die. The tap would screw into the battery.

No a atty on a 510 is male so it would screw into a tapped out hole . A die cuts threads on a "male" screw or bolt.

Sorry stevo, i reread what you wrote and yes the tap would screw int battery and the atty would screw into a die but my question was if the end product of the tap, the tapped out hole would fit the atty. Just wasnt clear on my question but it was answered. i do use taps and die just about every day and know the difference and i see what you were saying, sorry.
