Taper tool DIY
from old saw blade and a piece of wood.

Making my shaving horse I realized that I needed a taper tool for future projects, so I tried to find an old one with no luck, and then I checked the prices for a new and realized I wanted to make my own…

After some looking at the web I found this page: and there a fine version that should be quite easy to make from some scrap and a spin on the lathe, so I went for it.
Thank you to greenwoodworking!

First step was to make the wood part.
I found an old piece of a parasol (why there are holes in the wood), and turned a cone shape, a piece for putting a cross bar and rounded the top for a comfortable grip.
All just by heart and feel.

Then some linseed oil.

Found a piece of old saw blade and a dowel to put through the tool and drilled a hole to fit the dowel.
The ruler is in cm (10 cm app 4 inch).

Cut the saw blade to length with a Dremmel tool.

Secured the tool to the table.
Then cut a groove with another saw that was a wee bit smaller than the one I was going to put in, so I had a secure grip after.

Now the blade could be mounted.

The flat side of the blade was given a 45 degree bevel.

Like this.

Can also be done with a file…

And here you see the tool ready to use.
It can be used with the beveled side and the saw tooth side out.
The saw tooth side in gives a good grip to the tool.

To avoid the shaves get stuck I cut of a ‘groove’ in front of the blade.
(Make sure it is the front).

Like this.

In an inch thick pine wood I drilled a hole for testing.

And with ease I could taper the hole.
It does an excellent job.

And so we can leave this post with a tapered hole and another useful tool in my workshop.

Here a little sketch from my sketch book for details.

The tool can be used for many projects like tables and chairs, but I choose to post it under my shaving horse since it would have been excellent there.

Hope this blog could inspire, and a special thanks to greenwoodworking,

Very useful tool Mads. It would also come in handy when making a tool cabinet to taper holes to hand chisels and screwdrivers etc.

Very inspiring. Thanks.

Excellent blog Mads. I am planning to make some better shop stools and I have been wanting to do the legs with tapered mortises. Your tool (or my copy of it) will make that happen. It’s seems that you have that rare ability to look at an object (and visualize many other not to obvious uses for it. Thanks for this great idea!
