Find a Good-sized Branch
This will be the base of your box.
We're basically going to hollow out the inside, so get a good size.
The starting branch here is a little to long, so . . .
If Needed, Trim Branch Down to Size
If your branch is from the wild and is kind of long, use your band saw (or other means) to cut it down to the rough size for your box.
Here, I'm using a 14" bandsaw with 6TPI blade.
Trimming Branch to Size, Cont.
There are a million ways to cut logs on a bandsaw, one way is to use the Carter AccuRite Miter Mill for Logs shown here. It's basically a sled that holds the branch as you slide the whole thing through the blade.
Sometimes it works, sometimes not so much.
Flatten/Straighten Ends
Usually trimming the box down to size winds up making a not-so-level-looking top and or bottom, so . . .
Flatten Ends, Cont.
One way to flatten is first to prop up your branch with clay or shims until it looks level.
Here, I used some clay under the branch to prop it up until it was sanding straighter. Then . . .
Flatten Ends, Cont. : Glue on Some Rails to the Branch
Flatten Ends, Cont.: Place on Router Table
Put the rails on the router table and raise the blade to just near the high spots on the branch. In the second photo you can see how the branch is tilting to the left and the right underside has the high spot.
Now . . .
Flatten Ends, Cont: Use Router to Flatten Bottom
Run the rail sled over the router and raise the blade and repeat until the bottom is even. Here is a video demonstrating this.
Flatten Ends, Cont: Remove Rails (Video Demo)
Pull off the rails from the branch.
This is a video demonstrating this.
Flatten Ends, Cont: Repeat for Top If It Is Uneven
You can repeat the router process to even out the top side of the branch, but you could also push the branch through the band saw with the bottom end flush against the band saw fence. Either way you are now ready to start the Band Saw box part of the project . . .
Cut Off Its Head!
This is one of the more confusing steps in making bandsaw boxes, but trust the art.
Sketch a rough line around the branch at about a half inch below the top.
Cut Off Its Head, Cont.
Then line the branch up against the bandsaw fence and carefully push the branch through the blade.
Trust the art.
Cut Off Its Bottom!
Admittedly not as dramatic, but repeat by slicing off about a half an inch slice from the bottom.
Save and Mark the Top and Bottom Slices
We're going to use these again later, and it's very easy to get them mixed up.
I recommend marking the outer and inner sides of both top and bottom.

Glue the Split, Glue the Bottom
Optional: Add Magnets
You can add a set of magnets to the top of the box and the box lid to help keep the lid in place.
First, tape a couple of straight pins or nails flat on the top of the box, then place the lid on the box and squish down.
Add Magnets, Cont.: Mark Pin Dents
... this will put indentations on the top ledge of the box and on the underside of the lid which allow your magnets to line up
Add Magnets, Cont: Drill, Glue Magnet Holes
For 6mm (aka 1/4i in) mini-magnets, I found a 15/64 bit worked pretty well. Drill the holes down a little deeper than the height of the magnet so glue and the magnets will both fit in the holes.
Add Magnets, Cont: In-lay Magnets
Remember to glue the magnets that are inlaid into the top edge of the box should be one polarity facing up, and the magnets on the lid should be inlaid with the opposite polarity facing up. Otherwise the lid will slide off. Yep been there, done that.
Sand Box and Lid
Sand the box and the lid with 150 then 220 grit sandpaper.
Sand, Cont. : Wear Protection
Be sure to put on earplugs and N95 mask. But put them on YOU.
Wipe Down Dust With Alcohol
Oops, Wrong Alcohol
hee
Burn
Now the fun part. Use a propane torch to lightly burn, like a well-done piece of toast, the box and lid.

Brush Off Excess Soot
Wipe Down/w Alcohol
Wipe down loose soot with alcohol of your choice.
Paints
I used a variety of acrylic paints, water-based dye, and alcohol. Oh, scratch that, I didn't used the Merlot.
Paint
I recommend applying the paint like you would stain: with a cloth. Note that gloves are really expensive these days so as a tip: buy XXL gloves, they are easier to remove and you can re-use them several times.
Let Paint Dry
As the paint dries, it will look chalky and ugly.
Add Polyurethane/Polycrylic
These photos show a box after its paint has dried and after polycrylic was applied. The poly will bring out a deeper, richer color.
Ooh La La
Enjoy!
