Hello,
I know the stock Crown coils are not “rebuildable” but I’m trying to rebuild them anyway as demonstrated in many youtube videos. Anyway, i just took an old Crown coil apart and had a closer look at the wire they are using. It looks like a thicker wire which is connected to 2 thinner wires:
Does anybody know if this can be done at home without using expensive equipment?
Thanks!

No metal specialists around? Welders? No DIY gods, mad scientists, hobby chemists, anything?
How do you disassemble the crown coil metal casing on the coil?
I think these new coils use a solder joint, but once you get the resistance right you should be able to use just a dual wire?
Joining wires seems counter productive what is its use?
This video is for the original crown coils
This can be done with 2 wires ( no need to weld or connect them )
I like to use a drill bit the same size as the original coil ID I think it’s more like 5mm
Do you wrap SS NI or what, and what size?
I have a bunch of dead crown coils
I use 316L SS you can go with 28g or 26g ( I like 26g ) 7 or 8 wraps
What ohm do you like ???

I have some 24ga SS316L but i found it ohms out too high. I like low ohm as long as it works, but i’ll order some better wire next payday.

Just play with wire gauge and coil ID to get what you like 
Just remember on those crown coils the smaller the coil ID the less airflow you will get. I would not go any smaller than 4mm ID
This is how to build the Crown V2 coils but will work for the original Crown coils
( duel coil build ) @Bad_Influence and @CosmicTruth check it out
The first video is quite simple, we don’t need to pull that inner metal part out of the coil, or the cotton liner. after watching these videos (again) I will be rewicking these old crown coils.
Thanks Rob.
Thats true the original coils do not need to be pulled apart just the V2’s
Not sure why they’re using this method on the crown coils. I thought that maybe you can avoid the wire getting hot anywhere along these thicker wires.
Yeah that makes sense…
I’m just trying to rebuild the 0.5Ohm coils as they come with dual SS wire. I think it is 26ga for the dual coil joined to a 24ga wire. I keep forgetting to take the wires to school where i could measure them.
I’ve seen the videos where they’re using 2 wires and if i can’t find an easy way of joining the wire I’m going to use this method. However… I’d really like to try the welded wire method because Uwell wouldn’t do it just for fun…
Not exactly related, but I have been rebuilding with these:
I have to say that flavor is top notch, no leaks, and that nasty initial flavor from the stock coils is absent.
I use the same method people have been using on Youtube with wrapping cotton around these and bending a lead…works in TC mode and Wattage mode…running around 65W (just like stock 0.25 duals) and loving it…By the way, if you get it down pat, the coil rebuild is about 10 minutes or less…
