First ribs in place...

... little to show for what is actually a fair amount of progress.

What has happened to get to this point?  Form selected.  Blocks squared and installed.  Outline traced onto the blocks.  C-bout curves cut into the corner blocks.  Curves cut on the neck and end blocks.  Ribs thinned to proper thickness and trimmed to starting height.  Bending iron fired up and curly maple bent into shape.  Glued and clamped into place.

Not shown -- the top and back plates are joined (individually, that is).

I find the other ribs much easier to deal with, so basically this fiddle is moving along into its second trimester.  Once the ribs and linings are in place, the outline can be traced onto the plates, and serious carving begins. 

This is my Hardanger, so it will have typical Hardanger f-holes -- a new adventure for me.

Note also in the photo, just right of center at the top, the plastic handle of a cheap chisel.  Even so, probably older than many of you reading this.  I bought it in the 1970s, just out of high school, working as a carpenter.  It is not what one would call a good chisel.  I had a good friend who would chastise me, if he could, for including such a piece of sh*t in my photo here, but he can't. 

And I use this cheap thing all the time.  Need to slice some old, gnarly glue out of a mortise?  Here you go.  Works as an old-glue scraper, too.  Split some wood into blocks?  Whack!  Won't stay sharp for a long, long time, but takes a good edge quickly and is just dandy, in this instance, for working blocks down to the point where my good gouges and scrapers can take over. 

What works, works.

Ribs and teeth

Thinning ribs with a toothed plane, to avoid tear-out in the highly flamed maple.  This side will go inward on the finished instrument.

An old task for me, but in a new context.  For the Hardanger, I'll go as I generally do with violin ribs.  For the viola, about 10% thicker.  So 1 mm and 1.1 mm!  Not much, but a difference.

Quitting time

I spend most of my time in the house, where my shop is, hunched over the bench, worried about bumps or awkward curves in my carving, thinking this new batch of varnish really isn't the right color.  Sometimes I'm practicing tunes, wondering if I'll ever learn how to play the fiddle.

It's nice to quit for the day, step outside, and see something that just is what it is.  Knocks me down a gear or two, and that's a good thing.

Light, and sympathetic strings (in the future)

Glancing light is a great tool for violin making.  With it, you can see how many (many, many) bumps one has on a surface, and it can even direct you towards how to remove them.  As I stepped outside the other evening, near sunset, I noticed these autumn leaves on our carport floor.  Note the shadows cast by these not-quite-flat leaves.

I decided to try my hand at making a Hardanger fiddle.  With some online research over the years, a plan from the Guild of American Luthiers, and a photocopy of the English translation of Sverre Sandvik's "Vi byggjer hardingfele", I decided to plunge in.  Since I expect I'll have enough problems with the basic mechanics, I decided to simplify some of the decorative details, such as the scroll. Instead of the traditional dragon, I wanted something like a canoe prow.  To get things uniform, I followed the Lancet arc, here described in "By Hand & Eye" by Geo. R. Walker and Jim Toplin.

It's a decent book, with practical methods for creating shapes in spaces.  My one quibble with the book is that the authors imply, maybe even state, they are not measuring when using a divider or a compass.  While it's true they are not reading a number off a ruler or tape measure, and then not using written math to divide or multiply, a divider is a elegant and exacting way to lay out work.  It is measuring, with extreme accuracy and precision -- assuming your divider or compass stays tight.

Their book is worth having.
