Coils Glow Outter side first

[PedroM]

I been trying to make coils for a goblin. I know the goblin is not the best for begginer but I found out too late. I have tried with 26 awg, but everytime I fire, glows outter side first.

Any Ideas what I'm doing wrong?

Hi Pedro,

If you can possibly post some pictures of that build, would help us to help you with this.

If I am understanding you correctly....Try scraping the entire top of the coil with a small flat screwdriver a few times then do a test fire, see if the coil fires evenly, continue this until it does.

those coils are in the garbage now, But ill try again and post pics

 

[MoDmAnDaN]

Ahhh, yes

I've tossed many a build cause they didn't seem to work very well. Thank god, most wire is cheap enough to do that and not feel like you've wasted money. And, it's good practice too.

Happy building!!

Yeah, if you've trashed them, make a new build. If it isn't doing what you want, post us some pics or a short vid so we can see what you're doing, and they are.

exactly. I think they call it strumming (like strumming guitar strings). It allows the coils to space out ever so slightly so you don't have any hot spots. And lightly pulse the coils at low wattage. Don't hammer them with a 5 second hit at 30 watts. I've had a lot of coils I made do the same thing and the strumming does the job perfectly.

short bursts of power till they glow from the center, squeezing with power off between, or strum

That was my night last night. The most frustrating night for coil building ive had yet. Nothing wanted to work for me. Got em up and running now though!

Been there done that! I have also gone back to just simple builds and stopped making complex ones like claptons and such. Sometimes, simple is better. Coils really aren't that difficult and don't over think it.

Thats just it....they were simple coils but the leg broke, or i couldnt get the legs even on both sides, or werent firing evenly, etc. Just one of those nights, i was the problem, not the coils lol!

Yes, simple is better. I use only single spaced kanthal coils. Never had a bad one.

I tried that and is working and is not. LOL. One of the coils glows faster and brigther than the other, but is from inside to outside this time.

You're halfway home

When building dual, quad, etc., coils, they have to be pretty much exact duplicates as far as spacing, wraps, leg length, or the power will be sent through one before the other. Also, check the tightness of the screws, they often loosen up when dry firing, causing one coil to heat up before the other. As far as the heat distribution, pulse the power, squeeze the coils (not while pulsing), strum, or reinsert what you used to wrap the coils, and repeat until they heat up from the middle to the ends. Also, YouTube is a good source for basic coil building techniques.

 

[PedroM]

Finally I get it right. Had some problems after strumming the coil (loose screw), but now I'm HAPPY. LOL

Actually I usually squeeze the coil between dry burns, should have the opposite effect of "strumming" but it doesn't.
