SPRING? . . . . .. what spring?

[pdib]

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 ?

The pin mod was a 2 phase thing. Shape gained some, and brass gained some. Sheathing existing pin in brass gained 0.15V .. . . the shape gained another 0.05V. Total gain was .2V. (I didn't test this at multiple resistances . .. so, consider that to be a rough estimate)

Well... i'm late to this party. with no mod on a 4.2v battery at ~.7Ω, under load I am at 3.2v. With the brassed firing pin, I am at 3.6v, and with the pin + shimmed spring, I am at 3.8v

I slept for ~24hr after getting home, so no fuse mod from my end at this point, but I certainly give the brassed pin and shim the thumbs up!

 

[pdib]

Oh, you did the pin too! Good on ya', monkey! Glad to see you got some decent results, and I wasn't just whistlin' dix. . .see!

 

[Xobeloot]

certainly not. a .4v gain from just the pin was incredible. I tested under full load on a 4.2v charge w/ both mods, but I have flipped the shim up to utilize the "turbo" on a discharged battery.

I know... yesterday's news...

Still exciting for me!

So, when you are able . .. . go get some full size 10A auto fuses. Same/better performance, + face.

 

[Xobeloot]

maybe tomorrow. if I wake up. i'm ready for bed before 5pm.... gah!

 

[pdib]

What, you don't have any fuses in your car? . .. . radio, fog lights, wipers



.. . . . better still . . . .. your neighbor's car

 

[pdib]

It's nice to have you back . . . . . ya' big ol' hairy ape.

 

[Xobeloot]

sleep goooooood... reo no make cough! zZzZzZzZ.... see ya tomorrow!

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.

Sounds good pdib thanks. I pushed the envelope and did a .3Ω coil. It worked and vaped great w/ the 15amp fuse.

1 issue. I melted my button. Luckily not enough to cause serious damage which I quickly fixed. I'm gonna order a few spare buttons.

The battery had no heat the mod itself had no heat it just pushed too many watts through the top firing pin.

At work so I just removed a coil on the fly and its working fine. I'm gonna look at at fixing this issue w/ the derlin button. I still haven't modded the top bar like you did so I'm not sure if that would solve the issue but I don't think it will since its a heat issue w/ the Derlin button's heat capacity prior to melting. The Battery's fine....I only used the 15amp one because based on Ω's law online calculator if I started off pushing 4v @ .3 that would be 13amps give or take so I didn't wanna risk popping the 10amp fuse b/c of it. Now at least I'm aware of this limitation in the design as well.

i mod the firing button too since i have melted about 6 of them!

Family and I are heading to walmart. Gonna dip in the automotive section for some 10a fuses and start rolling like Bee-dib. Yay-yuuuh

ST, what do you do to mod the firing button?

 

[Dturp]

ST, what do you do to mod the firing button?

Anyone know one of these guys that makes the glass drip tips? A glass button would be awesome not to mention it could handle the heat well enough and never melt. Although heat transfer would be something you'd have to test.

Here's mine. Definitely a keeper. That spare fuse in the grand is money. Mundy, like I said - money

And the fuse mod - Peter D - freakin off the chain. What a killer, simple idea. Note, it worked with no electrical tape inside on the back panel cause of the paint, but taking no chances of it wearing over time, I put some elect tape there.

Battery doesn't move at all. Tried a little self sticking rubber glass mount but was too stiff. Going commando on it and it's rocking.

Fantastic research, development and explanation pdib. You rock bro

Looooooooking Goooooooood, Supe! Lovin' the way you're lovin' it!

i mod it like this - epoxy resin glue and nickel rivet - read the pic as stage 1-2-3-4 from left to right. Finished pin on the right.

it'll short to your mod - uh huh! I wanted a firing button with a round profile since the pin makes an arc anyway, for better control. I prettied it with ceramic paint - but that's a waste of time.

never failed since.

Yeah, I've been thinking about your button lately, T. I might wanna try and copy you. I had forgotten how you attached it tho. Epoxy, you say. . .. . hmmm.

 

[supertrunker]

i thought about a nail but the delrin splits
