Here are some pix o the evod mod, more of a proof of concept than a finished job, I'll probably finish it when something stops working but for now this quick fix keeps on truckin.

Use the inside part from this fitting, this will become the (ground collar) for the coil- it is a bit hard to get out

Here the brass (ground collar) (with an air hole drilled into it) is mounted to the base of the coil along with a small o-ring to seal against the o-ring inside the tank. The collar on the coil needs to be cut down to easily fit inside the tank.

Installed into tank with a nano clearomiser tube (cut to length) the bottom of the nano tube is flat so it made for a nice fit to seal against the gasket on the coil. The coil can be removed from the bottom of the tank, leaving the tube in place.

Bottom view-note the shoulder of the (ground collar) is nearly flush with the bottom of the tank.

It seems these tubes are breakable, I was tyring to push it out from the bottom with a pen and this happened...be warned.

In my setup I put a wire through BB's original contact block for a ground wire and removed the gasket for the brass ground collar to sit in, so here is a shot o that....
