… I’m not skilled enough to build a flashlight without a threaded battery tube.

I would think a pre-threaded pipe would be allowed.

Yes absolutely. Didn’t DBSAR make a light using assorted pipe nipples and fittings a few years ago… contest 2 or 3 I think?

There are a few ways to make hand made lights without any machines or threaded parts, some examples of techniques I have used in the past for ideas:

Old Lumens Hand Made Tribute Light

[image] I received some parts from a giveaway by leroycp a few days ago and as I stated in that thread, I have made a light and dedicated it to Old Lumens.

He did seem to like my work with brass so I would hope this light might be to his liking too.
