Lol !!.. I have a whole new hobby now..I'm on a polishing frenzy !!

I can't seem to find anyone who sells 7mm X .05 bolts? It sure would make things easier...

There must be a SAE equivalent?

There isn't an SAE equivalent, and 7mm bolts are rare as hen's teeth. I've looked. There are a few out there, but they're pretty rare and expensive. There's a place in my area that makes threaded rod in whatever diameter and pitch you want. Check if there's one in your area. Usually you have to buy at least a three foot rod, but they'll make it if you want it.

7mmx.05 is the top contact thread and pitch right? i had the same problem at the ace and lowes, so i just picked up some brass knurled 8-32x3/4, im gonna cut it down to 1/2, find a nylon piece that will thread into that 510 and force thread the screw into the nylon or whatever material i can find..., still looking.

alright, now that i've broken the 5-post-barrier, i've got a question about voltage drop. generally speaking, but also specifically regarding the sig8, because there's one en route to me, and i'm a mech neophyte.

someone in this thread had posted-

"Hows the #8 voltage drop?

I had the #13 a while ago, beautiful piece of equipment, but such a huge voltage drop that it hits so pathetically and i just couldnt stand it, had to release it in the classies. Really a shame too - i like my mechs like i like my watches, solid and heavy, and that mech felt good in my hand."


based on this person's post, it would seem as though voltage drop is simply inherent to some mods; nothing to be done. but isn't that the purpose of all the modifications detailed throughout this thread, to reduce the level of voltage drop?

maybe a better question is, what are the known variables factoring into voltage drop?

thanks!

Main constraints are the types of metal(conductivity), Type of button(weather the current passes though a spring or metal on metal), And weather or not there is a battery spring(springs cause voltage drops unless made on a thicker more conductive material.
So it all boils down to the metals conductivity and where its placed.

When I spoke with john at vaportek he said that he was contacted by segelei and was told there would be a slight delay due to a problem they were having with the switch. As it stands now the ship date from sigelei is the 26th of April.

I was inquiring about the #19. Not sure if this effects the #20, but I would venture to guess that they were ordered together.

I have a #20 on order, I asked last night and he said that they have not come out and said that there was a definitive problem, that he was told that the 20 is still in testing, which to him means that they are fixing issues before they ship, and he was told that they would ship on the 26th of April.

all the information i've sifted through pertaining to mechanical mods in the past few weeks suggests that there doesn't yet exist a sub-$80 model that isn't necessary to modify in some way in order to achieve an acceptable level of voltage drop.

so my new question is, what's the cheapest, readily-available mechanical mod that is good to go as-is; out of the box? are there even such things? do people have to modify even their caravelas etc?

Everyone has a different level they consider acceptable. I find my 25.00 chi chi acceptable in the voltage drop department. I personally think the chi chi is fugly though.

If I were to suggest an entry priced higher end mod:

Paps 2.1
Mankos
Ea mod
Piccolo 2.6 or 3.1

Hybrid:

Noble 1 is decently priced. I have yet to use one but from reviews conductivity is stellar. Will have mine by saturday.

Hey, you know that they are called "mods" for a reason, right? ;)

Seriously, what WinchellNomNom said is spot-on. "Everyone has a different level they consider acceptable."

That applies to appearance, machining, features, voltage drop, and perhaps most importantly... price. Most of the voltage drop you might read people complaining about is in a fraction of one volt. Even the cheapest Chinese mod wouldn't have any market at all if they didn't perform at least reasonably "out of the box".

Most of the modifications you will read about are simple, inexpensive ways of gaining back even a tenth of one volt in voltage drop. They are small improvements to a relatively small problem. Bigger improvements aren't improvements at all... they are fixing design or QC issues that the manufacturer chose to ignore. Or they are completely cosmetic. And like anything cheap and Chinese you will find that out of a lot of 1000 units you may get an oddball that got too much of this or not enough of that. One guy complains about ONE unit he had the misfortune to purchase... This does not necessarily mean that the entire model line is flawed. :)

I LOVE my Sig #8 and hope I am at least as happy with my #19 when I eventually receive it. How happy? My Vamo collects dust now, unless I'm using it as a multimeter. I am SO glad I didn't buy a Provari because it would be serving the same purpose. Yes, I like my $30 Chinese mechanical more than I would enjoy a $200 VV mod.

thank you guys for responding.

one last question for the night, then. at what point is it necessary to start troubleshooting a mod for voltage drop? an entire volt of loss? two? when a contact point gets really hot? i know it's subjective, but what would you guys consider in the "performing well" range?

Me personally? Use the mod. If you feel part of it getting warm that is probably an area that can use a bit of improvement. This is often in the switch or a spring somewhere. The only part of my #8 that gets any warmer than any other part is the 510 end of it, when I'm chain vaping my Smok RDA at 0.9 ohms, and that heat has *nothing* to do with the mod or any "voltage drop" ;)

Did you read my last post with the link to the blog post on voltage drop? I think you will find many answers there.

As of now that'd be the China GG (Chrome version). For one, it is a kick-... Mod, performs exceptionally well. Two, at $26.99 u cannot get any other worth a mention. Three, though a Chinese make - it comes from the fine folks at Hoosier Vapes - ppl who r trustworthy and sell 'only' what is good.

qorax, I know you've had both the CCTS and the Sig for awhile now. Care to compare?

I would either go with the CCTS (china GG) or the K100, both available at Hoosier Vapes. I have heard good things about the K100 and just ordered one yesterday and should have it either the end of this week or beginning of next week. I consider the CCTS as kind of cheap. I guess it is mostly because of how thin the metal is and how it wobbles when in 18650 mode. The wobble I am talking about is where the tubes meet that allows it to telescope. Other than that, I would say it is worth the money. The K100 just looks really well built to me. Otherwise the Sigelei #8 or #13 is a good choice as those have been my main mods as of late.

I too have had both for a while. My chi chi is in a box somewhere. I actually lost the spring for the switch 2 weeks ago while trying to get it to perform like my #8. Its a great mod. Its just that once I got all my contact points on the #8 sanded down, its been hitting like a dream. I am no longer having to wrap my coils down to .5Ω to get my desired vape. This is how I have overcome all the voltage drop in my mods. I am happy to say I am back to 1Ω coils now and still having a great vape.

Also If anyone wants a cheap mod with low voltage drop, have a look at the moneypenny mod. its all copper and ugly as hell imo but it is getting great reviews.

I have never sanded any contacts. I just got a #8 yesterday(from Hoosier as well, those people are great!). What contacts do I need to sand, what do I need to take apart, and what grit and or tools do I need? Any help is greatly appreciated.

Nothing!
U don't need to do anything unless (A)u want to, OR (B)something is getting heated-up. I'm using my #8 a while now - and haven't done any DIY... neither have replaced the LR-cartos on my F-16(!).

Congrats on ur purchase!
