# How to make a bowl from a flat plank

This instructable will show how to make a bowl from a single plank of wood, using only a jig saw and wood glue, the bowl could be mounted on a lathe to clean it up but is not necessary. This is a great way to get a nice large bowl from a cheap piece of wood.

## Step 1: Materials

Materials and Tools:

-jig saw or bandsaw with a tiltable table.

-compass

-pencil

-a plank of wood atleast a 1/2" thick

-a strong woodglue

-sand paper

-optional lathe

## Step 2: Measuring (ya sometimes you have to)

Im no fan of accurate measuring when I build things but this is one of the times its difficult not to.

Begin by marking a center line down the middle of your plank of wood, then mark the middle of this line, this is where you will put your compass.

Then mark in even increments along this center line, these will make up the rings of your bowl. The distance between lines is up to you, If you make the distance the same the as the thickness of the plank then there will be no "steps" in your bowl. I chose to have small 1/8" steps in my bowl because I think it looks quite interesting. This made my lines a little less than 1" apart . I drew six lines, the biggest being about 14" from the center and the smallest being about 8".

Now take your compass and seat it securely into the center mark you want it to stay here for all the circles you draw so they are all perfectly concentric. Then use it to trace out circles that meet all the lines you just drew.

You show the saw set at a 45 deg. angle, but those look more like a 30-35 deg angle.

Having seen my father work great things on the lather, bandsaw and jigsaw i can appreciate the time and patience involved with this. I wonder how well it would work if you created a wave in the bowl? If you labeled the pieces from the bottom 1,2,3... and you created a bit of a stepped pattern?
base -1 -2 -3-4 then put five glued under 4 to create a rim of sorts?
Great instructions! Got the mind moving for sure!!

thats a scroll saw not a jigsaw. a jigsaw is the hand held saw with the blade that goes in and out

Looks like a hegna saw(or how ever you spell it) that we have in my d.t class at school

Another possibility, without cutting clear down the center line, is to just feed into the saw to the circle, and then glue the cut back together after the circle is cut.

Good job event need a complicated tool. You also a master of relaxation

Nicely done. I noticed that you stacked the rings on top of each other, another method is to push each ring down into the preceding. Might be easier to center that way.

Very nice. I had been planning something like this for a while, only using a scroll saw. I think with the scroll saw I might get away with cutting all the rings whole, without halving first, by drilling very small starting holes.. Anyway, I like your bird feeder and method! I guess you can also do interesting things like alternate light and dark woods and things this way.

Thanks, and I think it could be quite easily done with just drill small holes to fit the saw blade through, I chose not to do this because my blades where to big so hole would be very noticeable. A thing to look out for if you do drill holes, is to make sure for the inner rings your drill the hole at the same angle your saw is set at.

Great idea. Makes me think of a Fresnel lens. But here, reversed effect (giving volume to something flat).

Looks great! And I can't fault you on Step 8 - you've got just about everything you need. ;)

VERY INTERESTING! I am waiting since two years ago the opportunity to do something so. But I intend to do two sets of cuts, not necessarily inclined. That is, first I will cut two slightly different diameter disks, then I will cut them in concentric circles and interlayer them. Using this method one can make the sound box of a musical instrument, too.
