View Full Version : The walnut hand plane: Part 3, shaping it, and using it!

From my blog:

Following the glue-up (http://sandal-woodsblog.com/2009/06/20/the-walnut-hand-plane-part-2-the-glue-up/), I clamped the plane for several hours. But I could not wait longer - if you have ever been in the maternity waiting room at the hospital, waiting for your first child to be born, you know what I mean.

I removed the clamps, cleaned up the glue on the bottom, inserted a temporary wedge to tension the plane, and squared the bottom to the best side on the jointer. After that I sanded the bottom using 150 grit paper on the cast iron table on the table saw; this is the first time I actually brushed off the fine dust after every two strokes of the plane on the sandpaper. Finally, I drew some outlines, freehand, on one of the cheeks, and cut to the lines on the band saw. A little shaping with rasps, and I ran out of patience - I had to try it out!

The first trial, on one edge of a walnut scrap:

This shaving looks good, but is it thick, or thin? I wondered, as I looked at it:

The shaving was just under two thousands of an inch (0.002″) thick:

Then I had to tinker with the shape a little more, until time to go to the house:

The mouth is still not quite right, as sometimes shavings will jam. I shaped the mouth opening to run almost parallel to the surface of the iron:

As you can see, I got careless with the file, and chewed up part of the cheek during two misplaced strokes (the unsafe edge…). I can barely see a little light between the tip of the iron and the front of the mouth, so I still have some room to refine the shape. I will keep playing with this new hand plane, and will use it in one of the projects I am working on. I’ve got to work out the kinks in the mouth!

The Brese Plane (http://www.breseplane.com/) iron is great - I did not even touch the sharp edge prior to this trial run!

I don't know for sure since I'm not a professional plane maker, but doesn't the front of the mouth have too much negative angle? It looks really narrow there, it makes me think one errant chip would get stuck and at worst, drag the chip on the bottom of the sole, leaving a track on the work piece.

Sam,

I believe that is the area I must now tackle very carefully. In the first trial runs I would be fine for about 20-30 cuts, and then a little jamming would occur. Today I will see if I can fix this, so it will work better. Thanks for your feedback! I have a feeling this was the same reason I was unable to plane the face very well, as jamming took place when I tried a full-width shaving.

For what it's worth, Al, my experience with filing the mouths of wooden planes is that a safe edge file--any safe edge file, even if all you have is an auger file--is totally necessary.

And you can grind your own safe edge.
