Segmented Woodturning…Dinner Salad Bowls of Mahogany and Walnut

Segmented Woodturning – Salad Bowls

Segmented woodturning is a joy for the wood turner and turning a salad bowl set on the wood lathe can be a rewarding woodworking experience. It is also quite gratifying to enjoy one’s dinner salad and one’s fine woodworking in the evening with family and friends using the bowls you have created in the shop. While the wood lathe can be used to turn wood projects that are quite utilitarian it can also be a source for creating wonderful wood art. It just takes a bit of imagination. Join me and learn how a wood turner makes segmented bowls on a wood lathe using the creative techniques of segmented woodturning.

 A person with a new idea is a crank until the idea succeeds.

 See the process of making a Salad Bowl by using segmented woodturning techniques.

Each bowl has 12 staved segments of mahogany and 12 vertical spacers of walnut. The staves for the segmented woodturning were cut on the ten inch compound mitre saw while the vertical spacers were ripped on the table saw and then sanded on the open drum sander. As you can see in this picture the staves and vertical spacers are being prepared for the gluing process. The masking tape secures and aligns the joints while the yellow glue is applied. The tape will also serve as a temporary hinge for each joint when the joints are closed.

In the picture you can see the salad bowl halves of the segmented woodturning as they are glued. Notice that the bottom joints on both halves are flat to the table surface. This is important as these joints will need to be tight fitting when the two bowl halves join together. Two walnut spacers remain as they will be fit between the two bowl halves.

Wood Finish for Salad Bowls

Food-Safe wood finish for salad bowls

Once the wood turner is finished turning the wood bowls on the turning lathe it is simply time for any final sanding. To complete the woodturning project a food-safe finish is needed. A wipe on wood finish is applied to the wood turned bowls with a soft cotton rag. In this case Watco butcher block oil and finish is used to apply multiple coats on the bowls created by using the segmented woodturning process.

Turning on a lathe is enjoyable and you will find segmented wood turning to be a fascinating process. Once you start the wood craft of turning it may be difficult to stop!

Segmented Woodturning…Fruit Bowl…part 2

Segmented Woodturning…Fruit Bowl

This is segmented woodturning episode – part 2.
Be sure to watch the how to woodturning video: Wood Turning…a Segmented Fruit Bowl…part 1.

Segmented woodturning - Fruit bowl This sequel continues our study to learn of one of the great woodworking crafts, segmented woodturning. In this woodworking video our focus shifts to learn how to woodturn the segmented fruit bowl. We will also be sanding and finishing the fruit bowl that contains 24 segments of which there are 12 staves of light walnut and 12 vertical spacers of dark walnut. Beautiful ribboned mahogany wood is used for the base.

 

Segmented woodturning - Fruit bowl - Taping and gluing the jointsAfter the yellow glue has set-up it is time to remove the masking tape and packing tape from the segmented bowl. (In a fine woodworking project like this it is imperative that all of the wood joints are tight and free of gaps.) It is now time to start turning wood. We begin by mounting the bowl and leveling the bottom of the wall section . Taking the diamond parting tool we will create an interior mortise that will accept the tenon of the mahogany base.

 

Segmented woodturning - Fruit bowl - Mortising the baseNext we will determine the base size.To do this we will measure the outside diameter and the mortise diameter of the bowls sidewalls. From here we will rough cut the base at the band saw allowing for a slightly larger diameter.

After the base is cut on the bandsaw we will mount the base on the wood lathe so that we can turn the tenon to fit the mortise. Again, the diamond parting tool is used to cut the tenon and a dial caliper will gauge the tenon length needed.

Segmented Woodturning - Clamping the Fruit bowlWith the base mounted on the woodturning lathe we will take the segmented assembly and fit the mortise and tenon together. When we have a good fit we will then proceed with the glue-up of the two parts of our segmented woodturning.

After the glue-up dries and the bowl structure is complete it is time for turning wood and shaping the bowl. The segmented woodturning video reveals a spindle gouge with a fingernail grind for much of the interior and exterior wood turning. Other lathe gouges used for this sequence of wood turning include the following: A roughing gouge is used to remove the waste from the base exterior. Also, you will notice round and straight scraper gouges used on occasions as well.

Segmented Woodturning - Fruit bowl on the wood latheAfter the wood turner is finished turning the fruit bowl he will then switch to sandpaper to remove any marks left by the gouge. The wood turner changes to a finer sandpaper grit as he proceeds. Typically, he will take sandpaper sheets and tear then into quarters. He will then tri-fold a quarter sheet and sand with that as the wooden bowl spins on the lathe. This fruit bowl was sanded to 220 grit sandpaper and then burnished with the wood shavings. To prepare the wood project for finishing the bowl was then wiped with a micro-fiber towel to remove any remaining dust. Our segmented woodturning is now ready for applying the protective finish.

The wood finish for the segmented fruit bowl started with an application of SealCoat and finished with three coats of satin Arm-R-Seal. This produced a nice and natural wood finish for the segmented woodturning.

Recommendations for beginning woodworkers: View the segmented woodturning video a multiple times to get a better feel for the procedures. Pay close attention to the different lathe chucks being used at various times to hold the wood. Notice the gouges being used and how they are being used. Be patient and take your time. Always practice safety around the wood lathe. Consider taking a wood turning class to become familiar with this woodcraft.

Segmented Woodturning video of the 9″ x 12″ Vase

Segmented Woodturning – 9″ x 12″ Vase

Segmented woodturning has taken its hold once again. In this woodturning video we are back at the wood lathe with our turning tools working on a new woodworking project, a segmented vase comprised of 18 rings and 432 segments. You’ll see the segmented woodturning process from the very beginning along with edited clips displaying the various wood gouges chosen to cut and shape this decorative vase of mahogany, cherry, maple, and walnut.

When the actual segmented woodturning is completed we will break out the sandpaper and illustrate the sanding process and prepare for finishing the vase. Initially, Sealcoat shellac sealer is used on the vase (inside and out). Once the sanding sealer has dried it is then time for a light sanding with 400 grit sandpaper. Next the dust is removed and we are ready for an application of Arm-R-Seal satin finish. Numerous applications of the wipe on satin finish are applied to the  vase once it is completely prepared.

(Note: all segmented wood has been glued with the same grain direction to allow for wood movement.)

Segmented Woodturning – Applying the Wood Finish

Segmented woodturning - wood finish appliedThe segmented woodturning, a vase of walnut and maple is mounted to the lathe chuck of the wood lathe. In this case the vase already has a preliminary coat of Sealcoat sanding sealer. It also has a coat of Arm-R-Seal gloss finish. The next step calls for a light sanding with 600 grit wet and dry sandpaper. Then all the dust will be removed with a microfiber cloth so that an application of Arm-R-Seal satin finish can be wiped on and evenly distributed while the wood lathe is turning at a low speed. Allow the wood finish to dry in a dust free area. Repeat this process until you are satisfied with the wood finish. Also, make sure to dispose of any potentially flammable rags  in an appropriate manner.

Note:

Segmented woodturning - vase with wood finishDuring this finishing operation of the segmented woodturning, it is imperative to be safe and keep the wiping cloth away from the lathe chuck. Otherwise, the cloth could be grabbed by the spinning lathe chuck. For the same reason, it is also very important to use caution when applying the finish near the mouth opening of the vase. To avoid any chance of spontaneous combustion in the woodworking shop, remember to safely dispose of any and all rags containing flammable substances.
