Further Adventures In Hand Planing

Planing dulcimer fretboards to proper dimensions.

I once wrote about developing the skills to accurately plane parts to proper dimension. I have recently been making some changes to my planing technique to accommodate the capabilities and lack of capabilities of my body.

Some physical issues make it challenging to do as much planing as I have done in the past. I thought I might have to get a thickness planer and jointer to do some of the work I enjoy doing by hand. After further thought I chose to reconsider my approach to using hand planes.

Until recently I got rid of lumps and bumps, hills and valley, Satan’s minions, and anything else in the way of a smooth, square, flat surface by using a jointer plane early in the process. Using that wonderful, big, long, and heavy plane repeatedly does not make some of my body parts happy anymore so now I take out the lumps and bumps, hills and valley, Satan’s minions, and anything else in the way of a smooth, square, flat surface by relying more on smaller planes and then finish up with the jointer plane.

Either approach has long been in use by woodworkers and luthiers but the latter works better for me now.

I also recently acquired a skewed low-angle block plane with a fence that makes getting the sides of the fingerboard assembly square to fingerboard much easier. I used to leave my fingerboards a little wide so I could true them with the jointer plane and have enough wood to remove in order to get the surface both straight and square; this usually involved some trial and error and the extra wood provided a margin for error. Now I mill my fingerboards a little narrower and after getting the sides straight with the jointer plane the skewed low-angle block plane with a fence lets me square the surface using light, delicate cuts.

All is well in the tiny, happy part of the world that is my workshop.

Shaping dulcimer braces with edge tools.

Last night I realized this blog started in 2007 when I returned to dulcimer making following a 25 year detour. Since then my dulcimer designs and methods of work have continually evolved and this shows no sign of changing. This makes me happy!

As I continue to learn and develop skill with hand tools I am drawn deeper into older methods of work. Shaping wood with sharp tools appeals to me and I find comfort in knowing that if the power goes out I will still be able to work!

In the photograph above I have just finished shaping a spruce back brace. The shaping began with a low-angle block plane, then a finger plane, and finally a scraper. The next step will be tapering the ends of the brace with a chisel and fitting them into the side kerfing.

There was a time I felt obligated to sand back braces because I worried some imaginary person might think my braces looked rough because I “skipped” sanding them. Lately I think differently; I see the small facets on the brace that show I shaped them with edge tools. I see the slight irregularities edge tools leave behind. I see that I had been there and I had done something. Again, this makes me happy.

None of this means I will never sand braces again. It means I like following my intuition and inspiration. Creativity is never static.

Happiness Is A Sharp Chisel!

Happiness is a sharp chisel!Each time I start a new dulcimer or group of dulcimers I take an hour or two and sharpen everything in sight. Occasional stropping keeps my tools sharp but starting a new project is a convenient time to do any necessary grinding and honing.

Since I work in a small shop almost everything happens on the bench. In the photograph above is the setup I use for honing. It is nothing more than a bench hook on which I place my sharpening stones.  When not in use the bench hook, diamond stones, and fine water stones live on a shelf and when in use I move it to the bench. The coarse waterstones live in a container of water near by. I usually remember to feed them. I use the same spray bottle I use to mist sides during bending to spritz water on the stones.

I prefer using waterstones because I get a lot of feedback through my fingers while honing and quickly achieve a polished edge. I bought the diamond stones years ago. They are handy when honing a narrow tools that could easily gouge a waterstone but as I have gotten better at using waterstones I rarely need them. When the waterstones need flattening I lap the coarse stones on a cinder block with some water and lap the fine stones on the coarse stones.

On the other end of the bench and not in the photograph is a cherry dulcimer about to receive frets. As I said, everything happens on the bench.

Well, almost everything.

 

Plane Crazy

Many small planes equal one big plane.

In the photograph above is a small heard of small planes. I really do use all of them though not at the same time. There’s also some small spokeshaves keeping them company.

After shipping a dulcimer this afternoon I got the urge to do some deep reorganization in the workshop. This is never a good idea.

I did some less destructive cleaning and reorganization in the shop several days ago and now I can’t find a few things. My shop may look chaotic but it is my chaos and I understand how it works! Organization does have certain advantages but an organically grown chaos can have its own hidden sense of pattern and structure.

An artsy-fartsy shot of some planes on a shelf.

While cleaning and reorganizing these shelves I decided to put the planes I rarely use in storage. There is empty space on the shelves now. This has never happened before. I’m sure it won’t be there for long.

Young and old planes in love and three dulcimers in progress.

When posting picture of planes on a shelf someone will usually comment that I am storing them blade down. Many believe you should never store a plane blade down because the blade will become dull or get nicked.

These shelves are soft pine that has become wavy and warped. I don’t worry about the soft pine touching the blades and on the larger planes the warp in the shelves often keeps the blades from touching the shelves.

I strop my plane blades and chisels often so one way or the other they rarely become dull.

Yes, my life is this fascinating.

Laying out a dulcimer peghead support block.

On the bench is a cherry dulcimer ready to receive its peghead. In the photograph above is the block that gets glued to the end of the dulcimer to support the peghead. Layout lines are in place to guide the process of shaping the block.

Dulcimer peghead in progress.

The block is shaped and the gluing surfaces are flat and true for a perfect butt joint. I said butt, huh, huh, huh… Also in the photograph is the blank that will become the peghead and a cardboard template with the basic shape I’ll be using.

I use hide glue for gluing this joint. I could get an excellent, strong joint without clamping just by using a rub joint but I’m using a jack plane as a weight while the glue dries overnight. It is not necessary but it couldn’t hurt. Rub joints are made by applying glue to two perfectly mated surfaces and gently rubbing the pieces together until the glue begins to stick. After the pieces no longer slide I hold them in place for a minute or two and the joint is complete. As hide glue dries it pulls the joint tightly together.

A glue up that is far less precarious than it looks!

Here you can see the completed joint and a good view of the sound port; a soundhole in the side of the dulcimer. I use sound ports to change the frequency of the air space within the soundbox, get a larger soundhole without removing more material from the soundboard than I prefer, and so the dulcimer can be used as a birdhouse should the need arise.
