First Genesis - Richman Hybrid HELP

[tmel]

Hello! I got my Richman Hybrid in today and so far it's been great. I am a Reo user, but wanted to try a Genny and rebuilding is not new to me, however..I am having some issues.

I cannot seem to get rid of the hot spots properly on my wick/coil. I have 30g, 28g, 26g and 24g. I have only used the 28g so far with 500 ss mesh.

I have tried the Petar K method and I just couldn't get rid of the hot spots, or my wick wasn't going fast enough....My wick is 7/64 in diamater and I have been doing around my 7/64 bit 5 wrap coil around it and mounting it in my atty with the drill bit in the wick hole, once its straight, I slide my mesh in. I think my hot spots are due to my wick not making good contact with the coil, but I am not sure...

I have tried an unoxidized wick and an oxidized one, sometimes my coil would just snap instantly after firing, not sure why.

Do you guys think its an issue with my wick not touching the coils or my inability to fiddle with the hot spots?

I have a working 1 ohm setup. However, if I tilt the mod down towards the wick, it will fire and not glow red. The moment I tilt it the other direction and it stops wicking is when the vape becomes extremely hot and it glows.

What am I doing wrong? Should I make a new wick?

Does the coil hotspot when their is no wick? I usually check first for hotspots before putting in the mesh. Then pulse it with the mesh in till the hotspots go away.

Pics of the setup would be nice to further diagnose.

Will post pics the next time I build it....my coil glows evenly without the mesh in.

You want the wick to slide easily into the coil but just enough tension that it won't fall out if turned upside down. You'll get lots of hot spot with a tight wick. You MUST work out hot spots with a dry wick.

The wire will move and shrink a bit when it is first heated, fire your coil numerous times without the wick to "set" the wire.

eta: Oils on the wick from your skin will hinder wicking, make sure you burn the oils off and use tweezers after.

I've always had better luck eliminating hot spots by wrapping the coil on the wick while it's in the atty. Good wire to wick contact is a bit more certain this way. Thicker wire seems to be easier to eliminate the hot spots as well, 26ga being much easier to deal with then 28ga.

In terms of wicking, I've got the best results using SS rope with a small wrap of mesh above the tank to wrap your coil on. The rope seems to work so well, tilting only seems to be necessary when the liquid level gets low.

I am almost out of mesh...what size ss rope is a 7/64 drill bit? and ungalvanized is good?

This time they all fired evenly eventually from the outside in while my mesh was dry. I think I messed up the top wrap between the positive post because when I finally put juice in it, major hot spot there that I couldn't get rid of it.

It seems that no matter how much I oxidize the ss mesh, I get hot spots which then leads to my coil snapping usually on the top wrap center.

I have stopped using 28G and moved to 30G.

2 ways I try it.....wrap coil around drill bit and install, fire, looks good, insert unoxidized mesh and fire, this is hit or miss. I've tried with it oxidized as well and I have a hard time getting the mesh and coil to make good contact.

Other way is install oxidized mesh and then wrap with 30G around it, this seems to work the best for me...however hot spots and my coils eventually snap.

I've gone through an entire 6x6 square of mesh already

I had a hard time learning how to fix hot spots at first. I try to wrap even spaced wraps pretty close together with 28 ga. try and have short even legs to the positive and negative screws making sure the Mess is just a little away from the positive pin-not touching. I did have better luck using stainless steel cable wrapped with mesh I wrap my mesh the entire length of the SS Cable but that's just my way. This kind of wick is sturdier and easier to wrap the coil[wick in in place already. After I oxidize my mesh and torch the SS Cable glowing red] and wrap the cable with mesh I put e juice on the wick. Light it on fire blowing out every 5-10 secs until juice is burnt off. Repeat. Then it is a matter of pulsing coil and using a tiny flat head precision screwdriver adjusting the spacing on the wraps until hotspots gone. Also try and use a partial drained battery [if using a mechanical mod] or turning the Watts/voltage way down on a regulated mod for pulsing. This helps not burning a leg off before you can adjust the wraps.

Also when I use just a SS Mesh wick I do a solid wick not hollow. Its stiffer and I find still wicks well,at the most may have tip some.

My goto genesis build is a kraken with ekowool wrapped stainless steel wire rope. The ekowool insulates the stainless steel wire rope so that prevents hotspots. You also don't get the metallic taste. I would defiantly recommend it.

I just ordered a foot of ss rope 5/64 and a foot of 3/32 along with 400 mesh.

I wanted to just try it with 500 mesh at first but, i'll try it with ss mesh wrapped around the cable. Seems more sturdy to wrap the wire around yeah?

Looking to avoid any eko wool/silica....hate that stuff!

What do you guys use to cut the ss rope? Will my little wire cutters work?

I think you pics look pretty good but if that's 30g and only 3 wraps, its going to get really hot and if there is a hot spot its going to snap. I would definitely use at least 28g and imo 26 is best. if your getting better results wrapping the wire around wick, give this another try with the 26g wire. first oxidize the mesh pretty good with torch, I do it some before actually rolling the wick. once rolled torch it a bit then quench, repeat this 3x's then drip some juice on it and light that up. now that the wick is pretty oxidized but not toast, install the wick in device. before wrapping anneal the wire with torch a few times to get it more supple. now do your wraps, not to tight but not to loose, if anything I would error on tighter side then to loose. make at least 4 to 5 wraps and the most important part is the top wrap to the connection. this connection is key and has to have the perfect tension. fire device at a low voltage and work out hotspots with a tooth pic or something while the coils are firing. the good thing about the 26g is it wont pop while working out hot spots. once you have eliminated the hot spots increase voltage a little higher and once again work out HS, keep increasing until your vaping voltage and eventually you will have a nice working coil. only after this is successfully done, then add juice. I like running without fill hole screws and a fairly tight solid 500 mesh wick with just a very tiny center hole. this oxidation method maybe older school because it does oxidize the wick more then the pulse method but it worked for me for a long time, once you get the hang of this method and become proficient, then start messing around with other methods. as long as the wick has a good coat of oxidation you hotspot issues will decrease but that top wrap connection is still the key and needs the right tension. once you get a hot spot issue, mess with the top wrap tension to the post, most times this tension will be too tight.
