Made a router plane or OWT.

[Kees Heiden]

Copied from the Seaton Chest book, a router plane with the iron from a wooden plow plane.

Drilling the holes. I completely forgot to take more pictures from the build, but it is quite straightforward. Opening the holes with chisels, bedding the iron, making a wedge, moulding the front with moulding planes etc.

Here she is in action. Nothing special, just flattening the bottom of a groove. Bedding angle of the iron is 65 degrees.

And the underside. Showing why it's called an old wifes tooth.

Nice one Kees.

I imagine that one of the advantages of these Granny Tooth planes is that they require less space in which to work, unlike the metal router planes with a longer blade "foot". (I made a blade for the Veritas that is similar to a plough iron for this purpose).

Nice tool Kees!

[Kees Heiden]

Thanks,

And yes Derek, that is an advantage too. Especially in carving stuff, or when making small mortises that need a clean bottom (for whtever reason).

Cool, but is this more of a scraper than a plane? I ask because it look like the tooth comes straight out of the plane (at an angle of course). I don;t see the typical tooth of a router plane.

[Kees Heiden]

Indeed Pat. Bedding angle is 65 degrees so it scrapes more then cutting. This can be usefull sometimes when the resultant surface is visible and the grain contrary.

[Derek Cohen]

Kees, 65 degrees is still cutting - as depicted by your earlier photo.

The blade I made (from a hex key) is 90 degrees, so it a true scraper. It still takes shavings.

This is great for confined spaces, such as short mortices where flat bottoms are important.

There is a continuum from pure cutting to pure scraping and 65 degrees is somehwere in the middle.

Indeed. It's interesting to look at the wood structure under a microscope after cutting at various angles and on various grain orientations. As I think most people already know, the "cleanliness" of the cut depends on both angle and orientation.
