Brass tube size for threading connectors 801,901,510,400

[Cisco]

Hey Guys,

Just some confirmation that these taps and dies are a perfect match to the factory threads.http://www.e-cigarette-forum.com/for...1-510-4xx.html

So I got some brass tube in and went ahead and threaded them for 901,801,510.



For 901:
.3125 OD x .2285 ID x .042 wall thickness is a perfect match for threading your own connectors.The OD is a little to large but the die threads without issue.

For 801/510

.375 OD x .245 ID x .065 wall thickness. The OD is a little to large for threading for an 801 connector so I had to mill it down from .375 to about .355 for the die to catch without binding. For the 510 the ID had to be drilled out from .245 to about .260 for the tap to run without binding.

These brass tubes are the closet match that I could find. I got these brass tubes at Online Metal Store | Small Quantity Metal Orders | Metal Cutting, Sales & Shipping | Buy Steel, Aluminum, Copper, Brass, Stainless | Metal Product Guides at OnlineMetals.com, they have no minimum order and will sell in small quantity's. I am sure there are other web supplies also.


Cheers

Awesome post, big help!!!
Now, since you mill and drill (I don't have a lathe) can you sell me a foot or 2 of the pipe after you've milled and drilled it?
Pleeeeze?

So is it safe to assume that the O.D. thread is a 5/16-18 and the I.D. 1/4-20? I'm just guessing from the dimensions given.....

Oops, I guess I'm dumber than I thought. No 1/4-20.... all 5/16-18???

Im interested in the 510 part.

1) With your recommanded tube how did you drilled the inner diameter from .245 to about .260 ? With a .260 "tip" and a drill ? (not sure about the term "tip", my english is really bad..) or maybe you just grinded the ID with a dremel or something ?

2) I mostly want to thread my own 510 battery connector where I can plug 510 attys to mods .. RCA is working but i would rather use connectors. Question, once your tube is threaded, i guess we have to find a way to isolate the positive and negative inside the connector.. install a center piece.. how do you plan on doing this ? Any idea oh great lord Cisco

Thanks again for all the info, you solved so many people connectors problems with their mods, you should create a paypal donation link next to your name.

Heres a source for stainless tubing in small guages, if you don't like the chemistry between brass and juice:
