Hollow Vessels

Deep, enclosed forms turned through a small opening, built for the pattern to wrap the whole body.

The bowls and hollow vessels are my creations. I love building and turning my blanks with a vision of the final product and then watching the piece emerge from the raw form I created.

What goes into a hollow vessel

A hollow form is the hardest of these to build and the most rewarding. The wall has to stay even all the way round while the opening stays small, so every ring has to be right before it is glued.

I have discovered that I can stretch my skills and push myself to an even higher level with segmented turning. The possibilities are endless and intriguing.

Worked through a small opening

The inside is turned out through an opening far narrower than the body, which is what makes a hollow form its own discipline.

Even wall all the way round

Every ring has to be true before it is glued, because the wall thickness cannot be corrected once the form is closed.

How a piece is made

Polychromatic woodturning, commonly known as segmented construction: boards become segments, segments become a blank, and the blank becomes the vessel.

STEP 01

Select the wood

Domestic and exotic woods chosen for colour, availability and sustainability, from local Phoenix suppliers and resellers of traditional American hardwoods.

STEP 02

Cut the segments

Boards are cut down into small pieces, sized and angled so that the rings will close cleanly when they are assembled.

STEP 03

Build the blank

The pieces are rearranged and glued ring by ring into a form that will serve as the blank canvas for the piece.

STEP 04

Turn the vessel

The blank goes on the lathe and the shape emerges from the raw form, then it is sanded and finished by hand.

Straight from the workshop

Every bowl, vase and hollow vessel is designed, built and turned by David Kohler, then sold direct and shipped from Phoenix.

Question? Answered

How the work is built, where the wood comes from, and how to buy a piece.

What is segmented woodturning?

It is polychromatic woodturning, commonly known as segmented construction. It involves taking boards, cutting them into smaller pieces, and rearranging them into a form that will serve as my blank canvas. That blank then goes on the lathe, and the bowl or vessel is turned from it. It lets me form shapes and figures in a piece in ways that are not achievable with a solid block of wood.

Where does the colour come from?

Almost all of it is the wood itself. The materials are a combination of domestic and exotic woods from around the world, selected for colour, availability and sustainability, and the natural colours in those woods are what allow for the unique patterns and designs. New to the line are vessels that incorporate dyed birch veneers for dramatic and unique visuals.

Where do you source your wood?

Most of the exotics and imported woods are purchased from local suppliers in the Phoenix area. I use wood harvested from sustainable forests and managed plantations that use sound reforestation programs. Other sources are resellers of traditional American hardwoods, the same species our furniture and other goods have been crafted from for generations.

Do you ship?

Yes. There is free domestic shipping on all orders over $350.

Can I see the work in person?

Yes, and it is the best way to see how the segments come together. The pieces are at three Arizona fine art festivals in 2026: the Wigwam Festival of Fine Art in Litchfield Park in February, the Fountain Festival of Fine Arts & Crafts in Fountain Hills in February, and the High Street Arts Festival in Phoenix in March.
