The quick overview

I'll be honest. I have a drawer full of woodturning bowl gouges in my shop. But really, there are only a few key gouges you need to start turning bowls.

While much of the tool choosing process is based on personal taste and your unique projects, these tips are meant to provide guidance and give you a firm starting point as you choose your tools and develop your own preferences.

Step 1: choosing the gouge size

While choosing the right bowl gouge size for your work isn't an exact science, here is a general guideline. Note that our measurements are based on the outside diameter of the gouge.

For small bowls with a diameter of 12" or less, we suggest a 1/2" bowl gouge.

For medium to large bowls with diameters of about 12" to 14", a 5/8" bowl gouge will be more efficient.

For sizable work with a diameter of 14" or larger, a powerful 3/4" bowl gouge will really get the job done.

Keep in mind, that while larger tools can be more efficient, bigger doesn't always translate to better! Try different gouges and pay attention to which you are most comfortable with and which best fit your work.

Step 2: choosing grind profile & flute shape

While it's true that every turner has their own grind preference, there are three widely held bowl gouge profiles and flute shapes that are worth exploring.

Traditional Grind
An easy profile to sharpen, the traditional grind is nearly straight across, similar to that of a spindle roughing gouge.
 
This tool excels at handling end-grain fiber, and other difficult grains. Often referred to as a "bottom feeder", it is popular for finishing the interior bottom of a bowl and creating a smooth finish.
 
A "u" shaped flute takes well to the traditional grind.
Fingernail Grind
While a slightly more difficult profile to grind than the traditional, mastering the fingernail profile is worthwhile simply because it's extremely versatile.
 
Roughing, detailing, shear cutting, the fingernail grind can do it all.
 
The tool on the right has a "v" shaped flute, which takes well to a fingernail profile.
Swept Back Grind
Although a swept back profile is challenging to grind, once mastered it's recognized as the most versatile.
 
Excellent for roughing, scraping and finishing - it's no wonder this grind is used by many professional and production turners. Grinding the long wings first and finishing with the nose is a helpful technique.
 
A parabolic flute takes well to the swept back grind.
