Dual Coil RSST Build

[jjkillian]

I get burnt hits time to time on my RSST, so I wanted to go dual coil with it. I used the original fill hole as a second wick hole and drilled a 3rd hole to serve as the new fill hole.

My problem is getting the coils installed. Major pain in the .... just to get them to the negative. Where I am really having an issue is getting them both to connect to the center post. I basically cannot do it. I fiddled with it for a few hours last night. Just the slightest bump while wicking it will knock one or both off the the center post.

Is there a better center post, washer, spring, something to make the connection tighter/stronger? I have seen the silver center posts, but I don't think that is going to help any. A hole through a silver one would rock. Put both through the hole while holding down the washer and release I would think would solve the issue.

I am at .5 ohms on my single coil and am installing two 1.0 ohm coils. Both are built with 28g Kanthal with a .5mm ID. I am wicking the outside of the coil instead of the inside to get the dragon coil (saw in another thread) effect. So because of that set up I am getting zero support from the wick or anything else. Only the negative and positive post support the coil.

Thanks,

Interested of the answers you hopefully get from the experienced folk.

Also wishing the RSST had a more solid termination point on that center post. I would think a person could find a replacement post that threads the entire length of the post instead of partial threading as the stock post is. This would enable one to include nuts and more washers to tighten the positive lead(s) in a more, "Electrically Sound", fashion!

Maybe someone has this figured out??

Actually, between my center post find and your idea of just adding more nuts, I think we have the solution.

Silver post is way better for voltage drop and it is threaded the entire way. Now we just need silver nuts to go on it.

Actually, they were out of stock. Bought two of them here:

Thinking I will be able to find the nuts from a jewelry related site. I just need to know the thread

Same problem here, did you guys advance this or move on to other atty's?

I have my RSST setup with dual 1.4 ohm coils with XC116 wicks. Hits fantastic after drilling 2nd hole.

But those two wires up top are impossible hard to get attached. Have done it twice. Took a lot of trial and error.

I have a AGA-T2 that has stacked nuts instead of the spring and washers, but I found the down side to that is that it gets the center insulator too hot and tastes AWFUL once it burns.

An RSST with 3 posts with holes would be ideal for this.

try to make 2 coils on one wire. Like this TERRIBLE diagram below

I Do this with mine in autodripper mode but i use it on a stock deck, Modified cap though
