How To Shape A New Bowl Gouge Profile (Change, Reshape, Adjust)

Shaping New Bowl Gouge Profile Steps Image

Each bowl gouge angle and profile has a different use and function. You will need to shape your new bowl gouge to fit your needs.

When you get your first new bowl gouge, and if you’re new to turning, you might think, “so this is the bowl gouge profile grind I should be using.”

Not so fast.

Perhaps, if you purchased a high-end signature bowl gouge endorsed by a well-known turner, your gouge is pre-set with a specific sharpened angle and profile.

However, most new bowl gouges come with a basic standard grind that is okay at best. It’s up to you to change that bowl gouge to best suit your needs.

How do I shape a new bowl gouge?

You will need a sharpening station, and also, a sharpening jig (a grinding platform at a minimum) is very helpful to shape a new bowl gouge. You will need to grind your desired wing shape and bevel angle first, then create the shape of the gouge side wings.

We will cover all the steps needed to shape a new bowl gouge profile in this article.

Which Bowl Gouge Profile?

Oh, this is the most loaded woodturning question, if ever there was one. Ha!

Which bowl gouge profile is best?

The real answer is, whichever bevel angle gouge profile you prefer and works best for you.

As a wood bowl turner, you will need at least a couple differently ground bowl gouges to be used while you turn different types of bowls.

Yes, most of the bowl turning can be done with one bowl gouge, but additional gouges with different grinds help in numerous ways.

A standard ground 45° bowl gouge can be incredibly helpful when confronting delicate wood fibers that want to easily tear-out.

The micro-bevel bowl gouge is indispensable for turning areas hard to reach with a “regular” bowl gouge.

My Favorite Gouge Bevel Angle Profile

My favorite all-purpose bowl gouge is a swept-back winged gouge with an approximately 55° bevel angle. I use this style gouge to rough, refine, and finish almost every bowl I make.

For this article, I will be shaping a new bowl gouge profile to this 55° bevel angle and swept-back configuration.

You can follow these same steps, making adjustments for bevel angle and wing shapes, to shape or reshape any bowl gouge profile you’d like.

Hand Grinding or Jig System?

Hand-grinding a new gouge profile is possible, with much practice and experience.

I recommend using a sharpening jig system to not only make the process easier but also make it dependably repeatable.

In this example, I will be using the Oneway Wolverine Sharpening System to assist the process of reshaping a bowl gouge.

Other sharpening systems are available. I use the Oneway system because it’s simple, easy to use, and relatively affordable.

Shaping New Bowl Gouge Profile How-To

Safety At Grinder

Before we go any further, we need to be safe and cover some safety requirements while sharpening.

Eye protection in the form of safety glasses and a face shield is obvious and a must.

Many people overlook a very dangerous second hazard, dust. The metal dust from the grinder can be many times more hazardous than wood dust.

Wear your respirator at the sharpening station at all times.

I know this might seem like overkill, but you can thank me when you’re breathing easy many years from now.

Also, keep the tool centered on the sharpening wheel. If the gouge slides off to the edge of the grinder, it can get caught and be forced under the grinding wheel.

If the gouge catches and is pulled down, it can make a very violent sound and impact, not to mention the potential for damage and possible injury.

Cooling While Bowl Gouge Sharpening

The steel used to make bowl gouges is heat-treated and strengthen to withstand tremendous forces.

When we sharpen a bowl gouge, it is possible to overheat and weaken the cutting tip. Overheating can potentially make the gouge tip fragile.

To prevent overheating a bowl gouge while sharpening, stop frequently, and quench the tooltip in a container of water.

I keep a medium-sized container of water within arms reach of my sharpening station for quick tool cooling.

Work slowly and dip the tool frequently in water to prevent the metal from overheating.

If the bowl gouge metal turns color, it is overheating. Make more stops to quench the tooltip to prevent overheating.

I have contacted several gouge manufacturers, and they recommend removing any bowl gouge material that is discolored.

Continue sharpening as normal and grind away any discolored steel until the tool is free from potentially weakened material.

Grinding away all that material can be time-consuming and expensive, and it is also an excellent motivation to keep your tool cool while sharpening.

Establishing Bowl Gouge Bevel Angle

You will need to determine what bevel angle at which you will shape the bowl gouge.

I’ve written an article about the very lively topic of bowl gouge bevel angles, be sure to read this when you get a moment.

I will be making the profile angle of this particular bowl gouge example at 55° with long swept-back wings.

Bevel Angle Step One

Use the adjustable locking protractor to find the current nose bevel angle of the bowl gouge.

For the moment, we are not worried about the side wings, measure the bevel angle at the very front of the bowl gouge nose.

Bevel Angle Step Two

Adjust the flat platform of the sharpening system to approximately match the bevel angle you want for your gouge bevel angle.

On the more coarse grinding wheel at your sharpening station, preferably around 80 grit, grind just the front nose of the bowl gouge.

Bevel Angle Step Three

Use the protractor and re-measure the nose bevel angle of the gouge.

Keep grinding just the nose until it matches your desired bevel angle from the bowl gouge heel up to the flute.

Shaping Bowl Gouge Nose Bevel Angle

I’ve taken this bowl gouge and ground just the nose to a 55° bevel angle.

When you first do this step, you’ll probably have similar thoughts as I did initially.

“Oh man, I really screwed up this gouge now!”

LOL, don’t worry, it looks ugly and wrong, but it will all start to take shape soon.

Creating Top Side Wing Profile

If you want a more traditional grind on your bowl gouge profile, you will make relatively smaller wings.

On the other hand, if you want swept-back wings, you will be taking away more material on the side wings of the gouge.

As you grind down the side wings, its good to have a guide to follow. Let’s make that guide now.

Using the thickness of the bowl gouge shaft as a measuring dimension, the side wings of this swept-back bowl gouge will be about two times longer than the thickness of the bowl gouge.

Place a pen or pencil along the side of the bowl gouge, and use your thumb to mark the width of the gouge.

Now, without moving your thumb from the pen, rotate the pen and measure off two sections from the tip of the gouge.

You can use a marker to roughly indicate the shape of the top wing angle profile, from the base of the flute at the nose to the upper end of the wing.

Flip the bowl gouge over, so the flute is flat on the grinding platform.

Using the platform as a guide and for support, keep the two edges of the flute flat to the platform while you lower the tool handle.

Now, with the gouge flipped over on the platform, remove material from the top of the gouge to match the marker drawn shape.

Stop when the side profile of the top of the gouge looks right.

Shaping Bowl Gouge Profile Top Wing Shape

When this step is complete, the bowl gouge still isn’t going to look too pretty, but it’s getting there.

We now have the outline of the cutting edge of the bowl gouge.

Looking down on the bowl gouge flute, the inside curved arc at the nose will be the final cutting edge, once we remove the excess wing material that stands in our way.

Bowl Gouge Wing Profile Ground Stage

Setting Up Vari-Grind Jig

Place the bowl gouge in the Oneway Vari-Grind Jig and set the nose to a depth of two inches.

For my particular configuration, I use a jig setting at the fourth flat notch from the top.

In general, the steeper the angle on the Oneway Vari-Grind Jig, the longer the wings will be.

If you’d like a more traditional small-winged bowl gouge profile, try a setting on the first or second notch. This angle keeps the gouge at a more horizontal presentation to the sharpening wheel.

Start by adjusting the V-arm until the bowl gouge nose angle, mounted in the Vari-Grind Jig, is flush with the sharpening wheel surface.

Use a marker to mark the flat nose bevel angle and then rotate the sharpening wheel enough to scuff the marker on the gouge.

Bowl Gouge Set-Up Nose Angle Marker Check

When an even amount of marker is removed, you are ready to proceed.

If marker color is only removed from the top of the gouge, near the flute, loosen and gently slide the V-Arm inward, just a touch and try again until the marker is evenly removed.

When the marker color is only removed from the bottom area of the gouge, near the heel, loosen and gently slide the V-Arm outward, just a touch and try again until the marker is evenly removed.

Bowl Gouge Marker Test V-Arm Adjustment

Shaping the Bowl Gouge Side Wings

With the gouge mounted to the Vari-Grind Jig and the V-arm adjusted to the right distance and locked, slowly grind away one side wing at a time until the top cutting edge merges with and matches the top flute line.

Be careful not to grind too much on the nose. The nose of the bowl gouge only needs to be lightly ground and merged into the side wings.

When the full bevel angle, which wraps around the front of the gouge, is ground to meet the top edge of the flute, the new bowl gouge profile shape is complete.

Final Shaping Bowl Gouge Profile

Final Sharpening New Gouge Profile

Most sharpening stations have two sharpening wheels on the grinder, one more coarse than the other.

Do the majority of the shaping, as described above, using the more coarse sharpening wheel.

Once the bevel shape is complete, move to the finer sharpening wheel and lightly sharpen the full bowl gouge bevel profile using the same jig set up.

Now your new bowl gouge profile is ready for the lathe.

Reshaping Bowl Gouge Profile

The more you turn, the more you discover the need for different bowl gouge bevel profiles.

You can take an existing bowl gouge and reshape and change that gouge to a different bevel angle and wing profile.

To reshape an existing gouge, follow the same steps as shaping a new bowl gouge.

The only difference when changing an existing bowl gouge profile, depending on the current profile, you may have to remove more material compared to starting with a new gouge.

New Bowl Gouge Profile Conclusion

Shaping a new bowl gouge from scratch can be a bit intimidating at first, but once you’ve done it, you may want to shape other gouges as well.

Take your time, and before you know it, you will probably be experimenting with all sorts of bowl gouge bevel angles and profiles.

  1. Kent, I have gotten a lot out of you sharping e-course. It help me in your bowl turning e-course. I like your teaching style. I have one question, what gouge do you start with to grind the micro-bevel and 40/40 gouges. A basic spindle gouge?

    Thanks, Bill


    1. Bill,
      Thank you for writing and sharing your kind words!
      The micro-bevel and 40-40 are bowl gouges. They can be any size, but for the micro-bevel I recommend at least a 5/8″ for stability in the bottom of the bowl. Be sure to see this article too >
      All the best to you and Happy Turning!

  2. A great article. Most articles on Sharpening start with a properly shaped gouge leaving out the critical step of first establishing the top grind angle. Your step by step explanation with super pictures will make ir easy for new turners to get their gougeds ready to make shavings. Very well done.

    1. Steve,
      Thank you for writing and sharing! I’m glad this was helpful for you. Sharp tools are essential!
      All the best to you and Happy Turning!

    2. Excellent – i have looked all over the place for advice on how to shape properly and this explains really well with excellent pictures as others. Have said. My initial attempts, following the usual jig instructions, ended up with a very pointed bowl gouge and me scratching my head to understand why… Thankyou

  3. Hoping I can find this same article, but for a Sorby ProEdge system. I bought a bowl gouge second hand that I’m trying to get this specific grind/profile on, but having some trouble.

  4. Hi Kent, I just recently started turning. I was unable to keep a consistent angle on my bowl gouge so I have been using carbide tools because I couldn’t make it work. I just received the varigrind jig for Christmas and have seen other videos on how to sharpen but they were intimidating. This article was worth the entire price of the course! Thanks so much. I now have a beautiful uniform bevel and am looking forward to how it will cut.

    1. Allen,
      Thank you for your kind words.
      I’m so glad this course is beneficial to you!
      Enjoy and Happy Turning,

  5. Hi Kent,
    I have received 2 brand new Roberst Sorby bowl gouges recently. One is 1/2″ the other is 3/8″. They came with the fingernail profile from the manufacturer.
    I’ve decided to “mimic the master” and duplicate your 55 deg swept back profile you use and will reshape the 1/2″ gouge to that angle and profile using the video and this article as my reference guide. My question is, should I also do the same with the 3/8″ gouge or should I go with a different angle and/or profile?
    I would think that having the same angle will allow me to get used to holding both gouges in the same fashion.
    Your advice would be appreciated.

    1. Yes, keeping them both the same is fine and will make switching between tools easier. Happy Turning!

  6. Wow, your description is very detailed and you even how we get in trouble grinding the bevel of our bowl gouges. While I am turning, I use a stone to touch up the edge. Is that a good idea, or am I making things worse?

    1. Hello David,

      Thanks for writing!

      Yes, touching up a tool’s bevel edge between trips to the sharpening station can work for most tools, especially scrapers. However, the bowl gouge is a bit more touchy. If you can do it great, but it’s pretty common to make multiple facets on the bowl gouge when touching up by hand. If you notice the tool cuts well, but then stops cutting, you might be moving from one facet to another.

      Happy Turning,

  7. Thank you for writing this in language a layman can understand and for providing photos. Also, the reassuring manner of your tone is helpful.

    1. Thank you, Neil, for your thoughtful message.

      Much appreciated!

      Happy Turning,

  8. I have a varigrind and now that I have read this article it will help me to get the angle I need. I think I misunderstood the instructions that came with the system.
    This is a good explanation of the proper setup and the pictures help also.

    1. John,

      Thank you for writing.

      Yes, there is a lot of information to take in when you first get the Varigrind. I know I felt a bit uncertain at first.

      I’m thrilled this article is able to help you understand the sharpening system better.

      Thanks and Happy Turning,
