Scubagen Mods

[Scubabatdan]

Dan,

I had quite an interesting experience with the gennie wick. I decided to roll a mesh very thin and only one layer thick. 0.75mm diameter with a single layer of S/S. Was not easy. Anyway, I bent in a U shape almost like your twisted coil. The capillary seems to work much better and off course you can get a whole lot more turns of nichrome / kanthral around it for your ohms. So far I'm impressed with the result. Good clean taste. Good TH. Lots of smoke. (No flames yet though)....

Cool will give it a try!
I have been going smaller on the DSU wick size, will try smaller

Teach, if that's what I think I'm seeing, I would hesitate to vape that... It looks to me like you made yours out of acetal rod, aka delrin... I think whats happening is the coil gets really hot and the plastic is outgassing and yep, it burns the gas... I have a delrin scubagen right here that exhibits the same phenomena and im thinking it might not be the healthiest thing to vape.

I kept a close eye on the delrin... it was getting warm, but I backed it off. The flame was the VG from the wick. Might be interesting to see how far it would go though... hhmmm fire!

I don't think its plastic fumes, though it could be. I think all the ones that are doing this are a little bit off. I have 1 scubagen that I can fire repeatedly just as long as I want with the top off. That one vapes perfect. And then I have the FireGen. I'm still troubleshooting but I think its a) a short or b) the wire is not connected to the posts tightly enough. My ohmmeter isn't working so I have to get a new one to continue working on it. I don't think it is simply overvoltage as I'm at 4V with 5 wraps, same as I'm running the good one.

There are 2 differences in my setups that I know for sure. Firegen is running 70% VG, non-FireGen 30% VG. non-Firegen, springs and thus connections are very tight, FireGen, springs are not very tight. I'll work to bring them closer to the same setup and see what happens after I get some ohms readings.

I did have an extra coil or two on that one - and 100%VG.

Got a little issue myself... 2 wraps, shows 6ohms! I did notice I have a post thats a little loose, could that cause it? I have checked for shorts and everything is perfect. I am using 32ga Kanthal, 400 SS Mesh...M1.6 screws for the posts.

That sounds like added resistance from a weak connection somewhere in the build that needs to be found and fixed. Pretty easy to find where it is by checking resistance along the various electrical paths with your multimeter.

How many Ohms do you get when you measure a 12" piece of Kanthal 32?

You should get a reading of ~14 Ohms.

Whew, got the two new parts turned and threaded! installed the oring and it gives me perfect resistance when turning the air adjustment. I should have it finished this weekend. Will do a video explaining the parts in more detail.
ALSO... I should get my parts in for my lathe today new jacobs chuck for the tailstock, new bits and a knurling tool!!! YAY me
Now I will be able to knurl the various parts.

Grats on the parts. The knurling tools? What type? pics please? Can't wait for the video.

Ah yes... knurling... a whole NEW level of frustration!

Dan is there anything else you need for your lathe? Perhaps I have extras of something you need... I have a ton of tooling!

 

[Gummy Bear]

Dan,
post a pic of the lathe too.
(that's the one you got from your Father right)?

Well now you offer LOL, I just ordered a 5/8 jacobs chuck. Already have the JT3 adapter for it. Well PM me what you want to get rid of Right now I just reached my comfort level of the things I despritly needed to basic stuff.

Will do, yes it is from my father. It is a mongomery ward (Logan) 48" free standing lathe.

Dude... that's just so totally knurley... oh... wait - East coast now.... 2011...uhmmm, nice apparatus you got there Dan.

Okay it seems that the loose post was the issue. Tweaked it a bit and now it dumps out TONS of smooth vapor with 3 wraps. I'm not getting much flavor, but I think that is because I am stuck using a box mod that only gives me 3.3v loaded voltage, and I'm used to 5.7v...

Dalton, glad you got it sorted, enjoy those plumes.

Glad to hear you've figured it out.

I've been using my eGo batteries to run my Genisis atty.

It doesn't seem like you need much more voltage than that to run the genisis atty with 3~4 wraps.

If anyones chasing a scubagen 3 i have 2 that i'm parting with.

Built or needs building?

my scuvagen3 has been running over a week now, got lots of build-up on coil, its wicking great!, decided to clean off all that gunk on coil and mesh, didnt want to take apart to do it, so , the ohms are 2.0.
So i put it on my 5v box mod and hit the button till the coils burner off all that build-up of, build-up gone, sorta dry burned it but not much.got it a little red.
Put it back on riva batt, at 4.1 volts, and ,,,,,,BAHM!! plumes of Vapor,, alot better now. was useing nutty caramel very dark..
