Brass lined wood battery tubes?

Hmm…. What about a 2x26650 for a dst?

If there’s enough metal to ream the tube for the brass sleeve then it’s possible. I roll the sheet brass into a tube and braze TG seam. Then bore a piece of wood to fit the sleeve and epoxy it onto the sleeve and turn it on the wood lathe to shape. The threaded ends are bored with sandpaper wrapped but to a tight press fit and epoxied on. The ends are masked and the wood stained with a lacquer finish applied to a slowly spinning part in multiple coats.

Nice idea. I have some argentinian lignum vitae (verawood) that would make nice tube covers/accents. Dense and heavy but a pleasure to work with hand tools. Love the aroma as I work it. Nice olive green color after exposure to sunlight.

I haven’t seen that but feel free to query/share details on any lights you want to use it on.

This a great idea. I have been looking around for a decent flashlight with timber for ages !!

Very nice. You have just started the old grey matter churning over. Whats the cheapest postage to the US?

I wooden mind one of these ….

Cheapest would be just the threaded ends of a tube in a padded mailer. The least I’ve ever paid to ship one to Australia is $6-7. Fortunately the whole host isn’t needed, just the battery tube.

Yuk, yuk.

I’ve considered doing it without the sleeve and using an old style wire handle wrap to carry the current but haven’t tried that yet.

If all goes well I’ll soon be able to do better than just sharing . Currently waiting for the first opportunity to pick up a wood lathe given to me by a friend. Her cisplatin treatments take priority. My only handy example of ALV is the handle for a cane I made. Hickory and quilted pacific bigleaf maple. Strong enough I could lay it between two cinder blocks and stand on it.

Look forward to it. I’m looking for interesting figure in the grain along with other more mundane qualities. I tried some lacewood which is interesting but the dried sap pockets create some interesting challenges. I also need to replace my 14650 Micromag and have some oak for that or maybe walnut. One of the local yards has an ok selection of interesting species to choose from though not all are available in 5/4 thickness needed for 18650 tubes. For example the Lacewood, Walnut and Sapele are only 3/4 while Purple Heart, Cherry, Poplar, VG Fir, Oak, and some others can be had in 8/4. I forget what size the Zebra Wood is. I haven’t checked some of the other yards either and the small amounts needed might be available online.

If I tried to make one I know it woodn't work. How about if I give you some dimensions and I could glue it on my own built battery tube? How is your checkering skills to make it look like its knurled.

Hey RBD, I have quite a bit of heavily figured maple if you’d like some. I also have walnut, mahogany and even some curly oak. The maple is in whatever thickness you could want. The others are 4/4 and 8/4. I’d be happy to stuff a flat rate box full of whatever you could use if interested. No charge of course. Let me know

A tube to spec is a fine notion but I haven’t tried checkering. Bead blasting seems more appropriate since it enhances the existing grain texture. Know anyone that can do that? I wonder how much a setup for that costs. What wood are you thinking of?

That would be sweet. 18650 and smaller need minimum 4/4 square blanks and larger things like 26650 or Mag D tubes 8/4. I’ll send a pm, thanks.

I have no idea about what type of wood. Is there a list?

That looks beautiful. I wish I had a light that wasn’t black that wood match these.

Common softwoods are pine, cedar, redwood.
Semisoft are vg fir, poplar, mahogany, alder
Hardwoods are oak, ash, maple, teak, cherry, walnut, most fruit woods.
There are some exotic woods available like sapele, zebra wood, and Purple Heart though some of them aren’t around in anything over 3/4 stock(~20mm) so not good for 18650 tubes. The cherry in the op has just a natural oil stain and lacquer clear coat.

mhanlen, black ano can be baked to change the color to a brown-bronze-copper depending on the temp it reaches.

Might be doable. I’d have to see one.
