New: Dan's scubaqu only

Can't easily find all the pictures in the original thread. Please re post here if you have gotten the pyrex or quartz tube and lets keep this on topic so we have an easily refer to it. I should have some tubing today and am anxiously waiting to try this. The main reason I am excited about this is for many vapers that I have gotten off analogs that just don't have the mechanical abilities to deal with finicky genesis. A long lasting stable SS genesis would be great for them.

3mm glass with a 500 SS mesh powered with my .44 mini boost mod and an 18500 battery.
8 wraps of 28ga Kanthal A1 wire, 4.8 ohms at 6 volts.

BJ – Great Idea.

I will keep it short to the specs and pics. Hopefully the sequence below can help others. Details/commentary for my set-ups are in the other thread.

Version 1:
AGA-T, 5mmx20mm 4amp Fuse – Radio Shack (ID est ~3.5), 28ga Kanthal A-1, 1.7ohm #500 ss mesh rolled tight.
Glass tube length ~10mm
Results: Okay vape. Tried airflow in all different angles from wick


Version 2:
AGA-T, 5mmx20mm 4amp Fuse – Radio Shack (ID est ~3.5), 28ga Kanthal A-1, 1.7ohm #500 ss mesh rolled tight
Glass Tube length ~6-7mm
Results: Okay vape, but better than version 1. Best with airhole aligned with wick



Version 3:
AGA-T, 3MM OD / 2.4 ID Pyrex Glass – Wilmad Labglass, 28ga Kanthal A-1, 1.7ohm #500 mesh rolled tight,
Glass tube ~5-6mm. (just above airhole height)
Results: Good vape, still a bit airy, better vapor production, but quality still okay. Best with airhole aligned with wick


Version 4:
AGA-T, 3MM OD / 2.4 ID Pyrex Glass – Wilmad Labglass, 28ga Kanthal A-1, 1.5ohm #500 mesh rolled tight
Glass Tube ~5-6mm off of base. (Aligned with wick/airhole slightly above tube tip)
Result: Much better. Adding washer improved airflow/minimized non-coiled wire. Good vapor production, good taste, not better than coil-on-mesh genny.


Version 5:
AGA-T, 3MM OD / 2.4 ID Pyrex Glass – Wilmad Labglass, 28ga Kanthal A-1, 1.3ohm #500 mesh rolled tight
Glass tube ~4mm off of base, raised mesh 3mm above tube. (Aligned with wick/airhole slightly above glass tube tip)
Result: Very Good! Much improved vapor production, good taste, but not quite as good as a coil-on-mesh genny.


i used the same coil wire for all the Wilmad glass versions, so it pretty beat-up... Still work in progress: either coil isolation and/or improved air flow dynamics are next up.

Finally in the game. Got my pyrex today. First coil 8 wraps 30g 2.3 ohms on a 75mm 635. Wick to the top of the pyrex. I decided to try it with my diy Opus X because that is the juice I really know the flavor. So far I am impressed with the flavor and the vaper. Sure it take a little to get started but similar to my double draw on a cigar (when I smoked them). The first draw gets the fire going again and the next draw, full flavor. So far I like this.

How did you cut the Pyrex? Mine is coming on Monday. Thanks

Just scored it on one side with a mini file, wet the score with a little saliva and snap it.

 

[queenpanzer]

Thanks, I will give that a try. With my luck I will shatter the whole tube.
Good that I ordered three.

 

[beamrider]

We already have the materials to cut glass tubing....A light score around the tube, and heat the score with a kanthal loop. Few drips of cold water on the score and it should snap. That's how I used to cut glass bottles, it worked very well.

 

[queenpanzer]

What should I use to score it.

Deleted....off topic

Deleted...

 

[bapgood]

Don't Know what you are showing and yes wrong thread, we are trying to have just a Scubaqu thread for reference.

Deleted the post.....FYI PGS is a thin sheet that conducts heat 4-6 times better than copper...my thought was just to wrap it between the wick and the coil....the video was just showing that it worked with a little oxidation....I will keep the rest in the other thread or start a new one.

Now to get to my glass.

Got my 4mm .8mm walled pyrex in today. Cut several peices for testing. I went out and bought a $20 diamond dremel cutoff wheel. Wish I could of found something cheaper...tried a new razor, didnt put a scratch on it... they had a 3$ glass cutter tool but didnt know if it would work on pyrex... maybee one of them women nail files???

Anyway, snaps easily after scorring. I cut a few different legths to play with.

Played around with a short coil sized peice in my DFWvapor RAtank. Vapor production is volcanicly good but once the cap is put on its just nothing to brag about.

I had my air hole pointed right above the coil, taste is ok but swear i get a metallic taste from the glowing coils, not alot but its there.

Once I find some tubing to make a new topcap section that will be 4 or 5mm taller, I plan to add an aluminum baffle that will sort of make another chamber on top where I plan to have several small airholes all pointing at an angle to create a vortex. Hopefully someone will have success with this design in current genni tanks.

Ill post more findings after more testing

On capillary tubing a mini triangle file works great for scoring. Also thinner wall capillary tubes work better IMO. The 3mm I am using has .5mm walls.

Thanks BJ, this is exactly what I was wondering, the diamond triangle or half round file. My wife's nail file will remain hers.

The reason I cut my wick even with the top of the pyrex tubing was to reduce any down flow of juice on the coils. One of the factors that interested me was no burning of juice on the coils. Now after 3ml of vaping I am getting crud buildup on the bottom coils. It seams the vaper coming out on the bottom of the pyrex tube rises over the coils and collects on the hot coils. The pic shows this and also that I have to tighten the top wrap.

I have tried making an aluminum baffle - not much improvement, although you might have a better design than me. I tried trapping the air between the aluminum, and side of the cap, wrapping around the back of the cap to ultimately reach the coil. But I think that unless that air tunnel can be isolated (and by that I mean sealed; not being able to go out the top until reaching the coil) my design was flawed.

I was also thinking of a stainless tube at the airhole inlet that would be directed at the top of the wick to carborate the vapor - but have no materials to try it with.

Scubaqu-bamboo. 4 threads Lydias, 30g coil.

First burn at 3.6V, I am now vaping at 4.2v and it is great, clic on pic for video.

Scubaqu-bamboo. 4 threads Lydias, 39g coil.

Looking good. It also looks like there is less vapor coming from the bottom of the tube. Is that due to the bamboo or did you adjust something else.

I think it is the bamboo, also much cooler, no heat sink effect.
