It's nice, but takes some patience. You have to make many passes and test fits for the first piece but then after that you can just swap part and repeat for runs If you take very light cuts for the last few then you really don't need taps and dies to finish them either from what I understand.

It also helps to count the number of turns going into the piece on inside threads so you can stop in the same spot every time without having to guess.

Great advice zen and lorderos, I do use a magnetic dial indicator to watch the depth in and out and zero on the thread relief so I know where to begin with the internal threads. Bu5t I do need to slow down the RPM, thay will slow down the cut.

Yes, it's important to cut threads at slow speeds and when cutting harder materials use lots of lube

So Three .005" cut every pass with lots of lube and 2 .001" final cuts to clean them should get me some nice threads?

Dan, recently I tried your idea of cutting threads on the lathe then finishing with a tap, but I won't do that again, the lathe cuts cleaner threads than the tap.

The three passes with subsequent cleaning passes will make great threads if you have sufficient cutting lube. Remember there are two kinds of lube in the shop... Coolant and cutting... Coolant makes things slippery and cools... That's for long passes and depth cuts... Cutting oil ensures the tool will grab the work and cut.

Let's take up a collection and buy it for him lol let's see, 60 people at $500 apiece might do it.

500 people @ $60 bucks each sounds better.

Absolutely! Do the math right on down, start a list and see how many will sign up? Lol

Robert

 

[Gummy Bear]

now that's a co-op. with a purpose.

 

[Robert T]

Yeah, if Dan had that then no more price quotes from emachine shop!

Hmmm, If Dan was able to get 500 people to sign up for $60 + cost of material for a G-Tank-US and he turned 500 GTUS for everyone???? I really don't see a big problem with coming up with 500 people to purchase a G-Tank-US. Especial when you consider the future products that he would turn out...

 

[bstedh]

So Dan, You ready to quit your day job yet?

 

[Gummy Bear]

but then he would have to quit his day job and turn mods all day.

I'm in.

Careful, your next...

 

[MadmanMacguyver]

Watch out "busted H"(lol thats what I thought it was) Gummy WOULD take you up on it...me...I'd settle for a baby CNC in exchange for mod boards for life...been gathering parts for a $350 homemade one a la instructables.....cutting PCBs w a dremel sux and I haven't had very good luck w etching...

Got it all together, very little vapor, good to extreme throat hit, kanthal will glow from time to time, taste is super good tho.

Oh and I'm on six wraps on my 3.7 18650 batt mod.

That should get clean results, the first one will probably be more cuts till you get a good fit so you will be able to adjust from there, but 5 or 6 passes should be good. I know a couple of guys who take it even slower than that, of course the number of passes and death of cuts are dependent on the materials you're working on, but you know that already

That means too much wicking or not enough heat, both do the same thing. Try lowering ohms or increasing voltage. Also, sometimes you just need more airflow. If adjusting heat does not give better results then drill a very small hole in the vapor chamber tube the directs air at the coil. That should get you some really good vapor and tame the throat hit.

Ok..can't get it figured out as to why I can't vape at 5V with any of my genisis attys. No matter what I do...the ends of the coil between the post and mesh glow..and in most cases break. Doesn't do that with my 3.7v mods. This has a boosted switch and circuitry to handle the dual and triple coils, which the maker said actually increased the amps, wonder if that has something to do with it??
