This unique rasp<\/strong>, handmade by Liogier<\/a> in France, will allow you to deftly produce beautiful curves in your woodwork. <\/p>\n\n\n\n

The stitched surface is flat across its 30mm (1 3\/16″) width<\/strong> with a shallow convex curve (radius = 320mm) along its 160mm (6 1\/4″) length<\/strong>. The robust hardwood handles at each end can be gripped from the sides or over the tops to give you power and control with an in-line push or pull stroke.<\/p>\n\n\n\n

You will feel exquisite tactile feedback<\/strong> as you fair gradual curves such as refining bandsawn curves in a table leg or rail prior to final smoothing with a scraper or sandpaper. I suggest grain #10 or 11 for general furniture work.<\/p>\n\n\n\n

After years of wishing such a tool existed, I designed this rasp<\/strong> in my shop using wooden and sandpaper mockups, and extrapolating from other rasps. I experimented with various curves, lengths, and widths for the cutting surface, and also put a lot of time into trying different positions and shapes for the handles. I presented the design to No\u00ebl Liogier<\/strong> who produced it with his legendary skill. The result: c’est manifique!<\/em><\/p>\n\n\n\n

It is now available from the Liogier website<\/a> for \u20ac58, currently $66.57.   <\/p>\n\n\n\n

You may find it helpful to visit the post I wrote a few years ago about available options in tools for working curves<\/a> by hand, and the two<\/a> posts<\/a> about the process of fairing curves. There are two key points<\/strong>. First, distinguish between two different processes: shaping <\/em>the curve and smoothing <\/em>the surface. Second, when fairing (shaping) the curve, you need a tool that provides continuous tactile feedback of the developing curve. The tool must have sufficient rigidity and length to reduce aberrant bumps and troughs.  <\/p>\n\n\n\n

This new rasp<\/strong> is far better for fairing curves than other options such as an adjustable float, Surform shaver, or diagonally pushing the convex side of a half-round rasp. It also provides better control and power than do curved ironing rasps for this task. Shorter tools such as a spokeshave or scraper are less reliable for fairing. I also think you will find this rasp more user friendly than a compass plane or other curved-sole planes. <\/p>\n\n\n\n

Liogier is one of the two best-in-the-world makers of hand-stitched rasps<\/strong>, both in France; the other is Auriou. This video<\/a> shows some of the incredible workmanship that goes into these tools. There is nothing quite like using a hand-stitched rasp. This new design adds to the venerable repertoire. <\/p>\n\n\n\n

If you do give this new rasp a try, I’d love to hear what you think of it.<\/p>\n","protected":false},"excerpt":{"rendered":"
