How to build a coil for an RBA or an RTA
An RTA, as well as an RBA section of a sub ohm tank, will come with certain limitations. In most cases, there is not enough space in the deck for larger builds. Use your coil jig as a reference and see how big a coil you can get away with. If you think that your vape coil would end up touching the chimney, go with a smaller diameter build—you wouldn’t want to cause a sort. After getting everything ready, you can secure the leads in place and wick your coils.
