AGA-T Help Needed - Endless Hot Spots

I hate to disagree, but people new to setting these up are best served by making a coil with minimal wraps in my opinion. 28ga is going to require quite a few wraps to achieve a resistance that works well on common VV mods. With 32ga, four wraps (a 4/3 wrap actually) gets a pretty consistent 1.8-2.2ohm coil given the wick hole size on these AGA units. Fiddling with 4 wraps instead of ~7 is far easier for the person setting up a Genesis-style atty for the first time. If you anneal the wire first, a lot of the "springiness" is gone and coils are easy to wrap with proper tension.

Whatever works for you is always great, but keeping the number of coils to a minimum reduces the amount of poking and prodding required to get the coil working properly until you're more comfortable doing the setup.

i agree, i never like more than 5 wraps personally. but i did recommend either 28 or 30g, well maybe depending on wick size the 30g is best suited. with a cut off of 1.3 ohms a 5 wrap of 30g is still better than the 4 wraps of 32g imo. but yes the deciding factor is the amount of wraps and depending on the diameter of the wick it is hard to determine this, but i still hold fast about flavor being increased with a lower gauge wire. so not exactly knowing exact diameters, i would still say that if at all possible without exceeding 5 or 6 wraps, go with a lower gauge wire, then a higher gauge wire. in closing, i just like to give more options to the table, and once a user knows the amount of wraps and resistance cut -offs, of a device, that they should ultimately strive for a lower gauge wire.

Thanks for the help

Having the hot spot blues over here also. Thought I set up a good coil last night - everything checked out OK - but I decided to randomly check the coil after about 30 mins of vaping. Glowing bright orange on the leg from the + post to the wick. Poked, prodded, rotated, shifted, spaced,.....still can't get it to work. Rolled a new coil on the same wick....same story. About to try a third time. Glad I ordered a spool if Nichrome....

my solution for hot spots, twisting the coil. I use a spinning whip finisher, as seen in this video:

RBA Tools Part 1: Twisted coils with a whip finisher. - YouTube

and I'm currently running a 4-3 wrap of 28ga twisted kanthal, pulling in 0.66 ohms, and not a single hot spot or hot leg. for some reason, the twisted coil makes all the coils I build impervious to hot legs, I will get a few hot spots when first setting up the coil, but a couple quick adjustments and it is perfect. the spinning whip finisher can be bought online or at a sporting goods store, it's a fly fishing tool, for less than 5 bucks.
