Metro 2033 inspired "Trench" lighter pt 2

In my last post I got the design and cap sorted for the trench 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.

To do this I needed to create a screw thread in the neck.

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.

Then I took this F-F coaxial (satellite cable) adapter, and drilled out the plastic middle, leaving a hollow tube with threads on the outside that fit the lighter.
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

I still have the inner components of the lighter that I used for the screwdriver bit holder. The flint is long gone, but the wheel could still be useful, so I pulled it apart and took that. There was also a spring that is used to press the flint to the wheel, so I scavenged that too.


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.
