    Recently my friend (whom I live with) purchased a mini-lathe from a local consignment shop for $100. We purchased a few extra's (tooling) to allow us to start working with it. Neither of us have ever used a lathe before , but seem to be picking it up slowly.

    I wanted to make a tritium pod for my keychain, but decided to start by making one for my friend first. He supplied the four 2 x 10 tritium vials (2 blue and 2 green). This was made over the span of a few days. I worked on it for a little bit each night before going to bed.

    Originally I was just going to use a single 2x10 vial but got an idea for a single pod using all 4 vials. The aluminum rod was turned down to the basic shape and then was offset in the 4-jaw chuck to allow the 4 small bore holes for the vials. Next the material in the center was removed to cut into the bore holes for the vials, in turn creating slots. A small ball end mill was used by hand to debur and finish the slots and holes. After the vials are installed, an o-ring is cut and stuffed into the holes to secure them. A slit-ring was added to the op to finish it off.

    This was an great project that made me realize just how thought out your work has to be so that it flows in a process with minimal steps and zero back-tracking and one tiny mistake( slightly offset vial hole) . Maybe someday, I'll be able to make stuff like this in titanium...but for now aluminum will have to do.

    Hopefully the owner will be able to get it coated. Maybe HA III or DLC. We plan to cover the vials with clear epoxy for protection. Really happy with the way this turned out and I have something pretty cool (IMO) in the works for these 2 large vials that have been laying around...

    Thanks guys!:thumbsup:

    I have no plans to mass produce them, but would be willing to consider making a few for interested members with the understanding that they would not be perfect as they are done freehand, and I'm still very new to the lathe....no promises though.

    Just got back in from the garage and found the majority of the materials for the "other tritium projects"
    We are in the process of relocating the lathe to a new STURDY workbench and made many improvements to the surrounding lathe location.

    This first fob is going to be hard to part with! Luckily I've had a week to enjoy it!
    I have a few interesting ideas to try out and will update this thread or start a new one if it turns out as I hope.
    I'll keep you guys posted. I have a feeling you tritium freaks are going to like them....:evilgrin:

    I would love one of those or close to it.

    The only change would be larger tubes to hold the trit in a clear rubber/plastic tube for protection.

    I would pay for one, send me a pm if you would be willing to sell one.

    Nice work. Great design and I bet it is very bright with 4 vials.

    Very nice work! I have a penchant for tritium as well. Please let me know if you are planning on making some more of these for sale.

    Nice work! Very creative!

    Just a suggestion for protecting the vials... clear heat shrink tubing. It will provide more scratch and impact resistance than epoxy and you've already created a nice "waist" in which it could be set.

    I'd be interested in buying one of these, but I know it'd cost way too much for me.

    That has to be the best tritium fob I have ever seen.

    I would also like to see the holes slightly larger so you could cover the tritium vials in clear heat shrink or a very thin clear tube for protection.
