Sneak preview of the finished lighter
Wick & Fuelling
Most refillable lighters such as the Zippo refill from the bottom, but I didn't want to make unnecessary modifications to the case itself, so I decided to create a removable wick mechanism that would allow the neck to also be used for fuelling.
I started with this, and using a grinder rounded off the outside diameter until it sit snug in the neck. Finally added some solder to secure it in place.
Some wool strands twisted together to create a wick and pulled through this creates the removable wick.
Also at this point I filled the lighter with some wool padding to for the lighter fuel to soak into.
This just leaves the ignition source.
Ignition
The assembly was constructed from a piece of a picture hook, which was widened to accept the width of the flint wheel.
A small hole was drilled and a hollow copper tube attached to the bottom, where the flint and spring was placed, and held in place with a small screw. (see below GIF for clearer explanation)
This assembly was fixed in place using another plumbing olive around the neck of the cartridge and secured again with epoxy.
