Woodworkers or tool addicts?

I was recently in a chat room at The Wood Whisperer website and the conversation triggered me into thinking that there are two main groups of woodworkers: the ones that got into woodworking because they wanted to work with wood and make something beautiful with it, and the ones that are into tools and eventually use them to build something following a plan.

Don't get me wrong here, I enjoy using my tools, specially my planes, chisels and my new Japanese saw. I find it very relaxing to work with hand tools and getting thin cottony shavings with wooden planes. The sound of the sharp blades slicing through the wood and revealing a silky smooth surface with a beautiful grain pattern on a piece of wood usually takes me to woodworking nirvana.

But what drives me as a woodworker is the possibility of taking a project from the design concept to the finishing stages. The tools are just a means to work the raw wood and turn it into something that looks great and serves a certain purpose.

Lets think of a chair, it has a well defined purpose, you seat on it (at least I do!) either at a dining table, your desk at work or outside in the garden. And that is when design takes a major play in the game, depending on the function that chair will serve it will have different characteristics.

Furthermore, you can incorporate different design elements and materials in this chair, either to combine with the surrounding environment or to give it a certain mood. A chair with its arms open will invite the viewer to take a seat, if the lines are straight it will have a very formal look whereas if the legs are splayed it will transmit a relaxed feeling and will be right at home at a lounge or near an hi-fi system at home, welcoming the visitor to listen to a record or two.

Before you rush into your workshop for your next project and take those boards through the jointer and planer, take a little longer to think about the design: form, function, color, texture, materials, mood, the shape and thickness of each component and the environment it will live in.

All these factors will make the difference between a beautiful piece that feels right in its place and something that serves the purpose it was made for but looks awkward in its environment.

Japanese saws

I've been meaning to try a few Japanese tools for quite some time but only recently I decided to buy one. I chose to go with one of the most popular types of Japanese saws, the ryoba, which has teeth on both sides of the blade, one filed for crosscut and the other to rip along the grain (see photo above).

The other very popular Japanese saw is the dozuki, similar to the western backsaw, and is mostly used to cut fine joinery like dovetails. This is the saw to use when you want the finest cut.

But why Japanese saws? Are they different to the western saws?

The main difference is that Japanese saws have their teeth filed in such a way that they cut on the pull stroke, which makes it possible for the blade to be much thiner than on a western saw. This is because as you pull the saw to make the cut the blade is under tension, while on a western saw, the blade is compressed as you push it along the wood, thus the need for a thick blade.

The thinner blade means that it is possible to have a very thin kerf and together with the very clean cut that these saws leave, even on end grain, they are very popular in fine woodworking.

On a quality dozuki saw, the blade can be just .25mm thick with a saw kerf of .4mm. Yes, than thin!!

My experience with this saw has been great, I find it easy to control due to the long handle (nearly as long as the blade) and it produces a very clean and smooth cut. Even on end grain pine, it only takes a couple of swipes with a block plane to leave the surface ready for finishing.

Next to try are the Japanese chisels, but more about that on a future post.
