let me ask that another way....
who would care to send ME this stuff? ....
... and underwrite my insurance?

Woody (Mama), I'd be more than happy to send you one. You want? PM me.
By the way, Feisty Alice, you intimated, but I wasn't sure if you were joking. I made one with you in mind too. (let me know)
Took one for science!
I knew something fishy was up with the coil, so I took everything off, slid the door off and just watched as the short happened. Fast, efficient and safe. The fuse does its job perfectly and replacing it is easy and fast to do. When I get the copper vein I'm sanding that bad boy and adding the fuse there as well (I always like sanding that area, even with the spring). Also and this is very important, battery seems completely unharmed.
So, ChrisEU asked me to do a test. Short out the mod. Here it is. Turn up your volume and you can hear it pop.
. . . . .. instantly.
here's the button. (after)
the button is wet, not damaged.

i appreciate the offer, but i'll pass. others are far more deserving. i'm perfectly content to remain a voyeur.
besides, i take great pride in my overall propensity to do massive amounts of damage to various body parts. i used to design analog circuits, power supplies and such decades ago, but self-preservation morphed me into a digital engineer. much safer...
i have a tremendous geeky appreciation for all the tech and innovation, but i really am the poster boy for someone who should be discouraged from trying this
Hey pdib, so I finally made it on to the reo side, and the first thing I read is this. I mentioned to you before that we vape about the same res in coils, and man am I glad I stumbled on to this thread! Lots of possibilities. Thank you to you guys for testing this mod out. I'll be trying this as soon as my reo hits my hands.. And if you need some one to test your little contraption I'd be more then willing!!
Thanks again to you guys
Thanks again to you guys
Also, for those with the folded legs fuse mod that the legs face the door (if that made any sense) wouldn't using a piece of shelving felt or a strip or too of elec tape on the bottom backside of the door eliminate the worry of the fuse sliding forward?
So it may have been discussed but I'm too tired to read through all of the other posts right now.
Is 15amp too much?
It works fine but I haven't short tested it yet.
Either way to be safe I'm just rolling w/ a 10amp right now. At 3 bucks per box of 5 I figured why not.

after reading this thread (oblivious to (ignorant of) the electronic language here)...
Will vaping a .5 or .6 ohms coil on a stock brushed aluminum Reo Grand cause premature batt deterioration vs. a v-drop mod Reo G, or a mech pv that has better vdrop specs?
fwiw, my stock spring seems to lose its strength after about 6 months of regular use...
i'm getting intermittent misfires and think its the spring not keeping the pos. contact where it should be... should i be changing out my springs more regularly?

I am going to try the fuse mod guys and probably the dechroming of the 510 connection but a bit nervous about the firing pin mod.
I will have a read back over the thread to refresh my memory and see what's involved.
Does anyone know how much v-drop the pin mod is worth ?

Hey pdib, good to see you are still moving forward with the advances in eliminating voltage drop at every point, and even adding the safety aspect. I've modded many average tube mods by improving contacts and switch design with stellar results. I have my first Reo from the Aussie classifieds arriving any day, so all this info will go towards my own upgrades for the Reo when it gets here
I was worried that the battery was done for, but it seems to be the multimeter. It's reading all my batteries at over 4.24V in a curious manner, it starts at a random V like 4.18V, and starts going up. If the battery is fully charged it even goes as far as saying it's at 4.35V (all 3 of my batteries). I already ordered a new one, maybe the short happened as I was using the multimeter to measure vDrop and it trashed it. I'm waiting for 4 sony 30 amps but they sure take their time from Hong Kong .
.The most amp draw you would get from a .5ohm coil would be in the 8.4A to 9A range, so as long as your battery has high discharge rating of > 10A you should be fine. The only other way that *might* cause battery damage is the arcing from the stock pointy firing pin. Other wise the stock reo w/ hot spring should not cause premature battery deterioration. Now if you mod the reo and decrease the v-drop in the mod and vape at a higher ohm coil such as a .7 or .8, you will extend the battery life, which in turn will mean that you charge/discharge the battery less frequently, extending the life of the battery. (lets say you only get 300 charges per battery, normally that takes you 300 days, but with extended battery life it could be 350 days before the battery is bad)
The hotsprings are designed to deform when heated, so when vaping super sub-ohm there may be enough current going through the spring to cause it to start to deform. I would recommend changing out any spring when you notice that its starting to lose contact.
Not sure if this has been covered, but Atmizoo Meet The Bug | atmizoo vaping modware has a resettable polymeric fuse rated at 8A and is able to handle coil resistances down to 0.5 ohm. I have a couple of them but haven't tried putting one in my Grand yet, but it is definitely small enough to fit, but may need some kind of shim to take up extra space without the spring to push everything together.
That looks like it would be perfect for me! Thanks for sharing! It still may be too low of a trip current for our super sub-ohm friends. It might work depending on how well we can decrease the v-drop of the mod, I think I may pick one of those up for testing. I only vape at .8-1.2ohm coils so I wouldnt have any problem running that, I would be curious about seeing a trip time curve.

Hey, so the 15amp fuse took about 1.3 sec. to blow. This might translate to some battery damage and a melted button. (I don't know for sure). the 10A fuse has worked great for anything I've thrown at it . . . . Low .4Ω coils, for ex. and (specifications-wise) it should run everything we need. I would run the 10s, and if I started building, say, .2Ω coils, and the fuse popped .. . .. then I'd look at 15s. BUT, .4Ω is pretty goddanged hot when you've got most of your voltage actually reaching the coil.

I'm eager to see what you come up with, modmeister studiovap. I hope it incorporates, Aussie coin, a bee's wing and Kiwi beak
(oh, and a part from a 1970s transistor radio, please)
I'll have to go look at it; but (SeaNap) is this the kind of fuse that can be doubled - i.e. run in parallel - (like bapgood did with his PTCs)? . . . . .. double the capacity to 16A and cut it's resistance in half?
That would be super cool! I'd make a housing for that.
Speaking of housings; . . .. . FEMO anyone?
ADDIT: I just looked at the fuse . . . not a shape conducive to running parallel.

Also, just wanted to remind y'all. Another thing I've done with my added power (running at higher voltage), is to do some fatter, longer coils. Stuff that would heat too slowly with a standard configuration. I wouldn't be surprised if a nice 13 wrap w/ 26g wire wouldn't put out some great flavor (ballpark that at .7Ω). Maybe not for everyone (certainly not for every flavor) . . .. just a thought.
