Diz: A Turned Fiber Tool Project

Turned wood and fiber are a natural combination.  Think of the turnings on a spinning wheel, from legs, to spokes, to supports for the flyer.  Wood and spinning, kind of makes sense as they are both fibers after all.  There are lots of fiber tools that you can turn.  One of the simplest is called a Diz.A turned diz that is used to prepare fiber for spinning

A diz takes prepared fiber and makes it into a long uniform roving so that it is ready for spinning.  You don’t need to explain its purpose.  If a spinner is looking for a diz then they know what it does and how to use it!

To make a wooden diz we are going to turn a round piece of wood that is slightly dish shaped.  In the center we will add the holes for the fiber to go through.  It will need to be well sanded and smooth so the fiber doesn’t catch in the holes or on the tool.  The advantages to turning a diz, rather than using a credit card or metal washers, is that you can make the diz a size that is nice to hold in the hands.  Credit cards can bend and washers are very tiny to hold.  Your wooden diz will be perfect and a pleasure to use.

Turning a Wooden Diz

To give the diz strength to pull the fibers through you need to turn it like a bowl; the grain of the wood in the blank needs to be oriented at right angles to your lathe.  You can make several from one blank just make sure you don’t hit the screws holding the wood to the face plate.

Find the center of your blank

For this project I took a piece of linden and flattened the inside surface to attach the face plate to.  With a ruler and pencil mark from corner to corner to find your center point.Diz: Find the center of your turning blank

Attach the face plate to the turning blank

Position the face plate over the center mark, the intersection of the two lines.  Do not line up the wood screws along the grain or your wood might split while you are turning.  This will be more tricky with a four hole face plate rather than a three hole plate like the one I’m using.Attach a face plate to the blank

Mount the blank on your lathe

Place the face plate onto the drive shaft of your lathe.  Make sure there is clearance with the bed of your lathe and your tool rest.  Even with small turning blanks bring your tail stock up for additional support.Turning blank mounted on the lathe

Turn the blank round

At this point turn the blank round, using your bowl gouge, and slightly larger than the finished diameter of your diz.  I was aiming for 3″ in diameter and the finished diz is just under that size.  I was aiming for a size that was easy to hold and use.  There is no precise size for this tool so turn a diameter that looks good to you.Diz blank is turned round ready to shape the face

Turn the front of your cylinder

When you have your turning blank round, remove the tail stock and position your tool rest in front of your turning blank.Turn the face of the diz.

Use a small bowl gouge to dish out the face of your diz.  At this point you can shape the edge as well taking light cuts with your gouge.

Turn the back of your diz

This is the trickiest part of the turning.  As you have shaped the interior of the diz you want the back to match the same shape.  I use a parting tool to create access for the bowl gouge.  Measure the depth of your turning and add on the thickness you want.  Mark this line on your turning blank.  Use your parting tool on the left of the line to make sure you miss the bottom of your turning.Working your way down the back of the diz

When you are about half way through on the back, stop and sand / finish the turning.  (Here is more on my sanding process.)  Sand through to your finest grit remembering to wipe the turning off between each size of sand paper.  Finish the front of the turning at this time as well. You want to sand part way down the back as the outside edge of your turning will be held in a jam chuck later on and you won’t be able to sand right up to the edge.

Get ready to part off the lathe

The shape will narrow as you approach the center.  I used a narrow parting tool to help shape the last portion of the turning.  You don’t have to be perfect at this point as you will flip the diz and use a chuck to allow you to finish the back off really nice.  Use your parting tool to remove the turning from the lathe.Before you part off, finish the face and edge of the diz

Finish the back with a jam chuck

You can use a simple jam chuck and create an opening to hold the turning in.  In my case I used a 4 jaw chuck with a paper towel to protect the turning.  Ready to turn the back of the DizThis lets you finish the other side of your turning.  You only need to sand and finish the area that you could not reach before.Back of the diz sanded and finished

Drilling the holes

I drilled three holes into the Diz.  Just to confuse things I use imperial drill bits but the basic sizes I was after was 3mm, 5mm, and 7mm.  This corresponds to 1/8”, 13/64, and 9/32.  Use a sharp carving knife or gouge to smooth out the wood where the drill bit breaks through.  Then fold your sand paper on one corner so you can twist it into the holes and make everything smooth.

Using the Diz

Taking the prepared roving pull, or thread, some of the fiber through the hole size you want to use.  Once the fiber starts coming through it will continue.  The end result is a long roving ready for spinning.  This article on how to use a hackle (another spinning tool) has more information on using a diz as well.Diz: A Turned Fiber Tool

Other Turning Projects

You can turn lots of projects for fiber artists.  Here’s a few that are ready to go:

  • Yarn Ball Winder         – ready to make a ball out of any type of yarn
  • Sett Gauge                  – a little tool to measure the grist of the yarn being used or spun
  • Shawl Pins                    – keeps the shawl on your shoulders and shows off the fibers and the wood
  • Needle Case                – keeping pins and needles in a safe place
  • Knitting Nancy           – for the young knitter, a great way to start

Wood and fiber go together so well.  Just remember that if the wood is coming in contact with the fiber it needs to be smooth.  You might have to go a step or two beyond your normal sanding practice.  This could be a new product line if you have connections in the spinning, knitting, and fiber world.

  1. Hi Robin
    As you do several projects for fiber arts customers I thought you might be interested in the Dodec spinning wheel. It is a woodworking but not a lathe project. I made one for my daughter a few years ago, she hasn’t used it much but she has many interests. This is a very simple, low cost, spindle type wheel (no flyer) There is a forum for this wheel on Ravelry, , and here is a link to the free plans. https://docs.google.com/file/d/0B6D_i4-AKeQ5a2JGRVRGYmFEbmM/edit

    • Thank you for the link to the spinning wheel plans. Interesting idea and could be adapted to some lathe work!
