hot spot on top of coil going from wick to post

[dwcraig1]

I seem to be really getting somewhere with this AGA-T with mesh, I start reading the posts and get ambitious and pull it out and work on it a little more. This time I can vape it without tilting it, in fact it's straight up and wicks good although the tank is near full. I think that I am almost there. My 28g wire and 500 mesh will come tomorrow so I am going to re do my other one tomorrow.

If if my aga is perfect and wicking i always tilt, just habit

I tilt it to use it normally but I just "testing" it.
There's no question about it, it defiantly does better tilted but I could never have it vape any good straight up on previous builds.

So your using 400 mesh?

Im using 400 on all my builds, havnt tried 500 yet and i have 2 x 12x12 sittin here

 

[dwcraig1]

So far I have only used 400 mesh and 32 nichrome but tomorrow 500 and 28g K

When the wire heats up it also contracts, especially in open air like the top of a AGA. Try having a bit of slack when you tighten down the top nut, or push your wick closer to the center post. When it heats up it will pull in a bit, but not so much that it shorts on the wick.

Yep, it's why a lot of builders reverse the wrap, between the top coil and the center post. In other words, if you wrap your coil clockwise around the wick, attach the end lead around the center post counterclockwise, and vice versa.

dw, i did mean the wire from the wick to the post, that little bit that runs to it, it just keeps getting super hot no matter what I do

That is what I thought but some folks might have confused it with a hot top coil

Just how big of a gap would you say is between the wick and the post? Can you post a picture of it?

 

[dwcraig1]

Here is the one that I added washers to last night, there is still some gap left between the wick and the post but it is half of what it was.

28 awg kanthal is gonna be a very hot vape... some people like it, I prefer the 30 awg... 3/4 wraps on a 69 mechanical mod.. that is =/- 1 ohm... can not wick vertical as the coil gets to hot and the juice will not flow that fast. But this thing blows clouds of vapor! Here.. look

 

[dwcraig1]

But I'm just now getting on to it, thanks the posts that I read here on ECF.




I've only run half a tank through it so far , it's getting better the more that I use it.

I was expecting my wire and mesh shipment but it got delayed until tomorrow so I went ahead and worked on my second AGA-T. On both I have added two small washers to the center post but I did something different besides that and I think I should mention it because I was creating a problem with what I was doing. Here is what I "was" doing, I was making the coil using the drill bit method and firing it till red hot before inserting the wick. This caused the wire to sag in places resulting in poor coil to wick tension in various places along the wick. When I put the washers on I put the shaft back into the coil and pulled it tight again, attached to post between the washers, slid in the wick and then fired (re fired) dry and well pretty much perfect. On both of them I didn't have to make any adjustment to the coil. I'll cut you guys a break, I'll not post another YouTube video of the second one

I received my 28 awg Kanthal and 500 mesh today but after picking up a few more ideas from this thread, particularly added two washers to the post, I am going to do nothing to my AGA-Ts as they are now working miraculously well. I'm going to just wait till the need re done

 

[dwcraig1]

I now decided to re do one of my AGA-Ts and I'm going to make a solid wick with 500 but the part that I'm not sure about is do I fold the edge of the mesh that is going to be on the outside of the wick. All my previous wicks I folded it.
So do I fold or not fold?

Edit:
I had some problems reducing wick diameter since it is some what solid, lots of wraps of 28 k wire @ 2 ohms
It's pretty wild

I always fold. About 1/4".

Sounds good to me ,thanks

One thing that doesn't get mentioned a lot, which I just thought of: When you look at your mesh, before you roll it, there is a "grain" to it. You'll see it. Make sure the grain is lengthwise, not across, when you roll. I don't actually know how much difference it makes. It's just something I do. Every little bit helps.

 

[dwcraig1]

I had wondered about the "grain" as I had noticed it but forgot to ask.
