My Acoustic High-Precision Thickness Planer

My Acoustic High-Precision Thickness Planer

Nothing original here, just an old trick that makes quick, quiet work of squaring and evenly thicknessing wood.

A few drops of super glue temporarily hold two wood runners to the bottom of a plane, in this case a Stanley #5 1/4 for those who care about such details. The plane can not take off wood below the height of the runners so repeatedly planing wood to the same height becomes easy. The top and bottom of the workpiece will also be parallel.

In the photograph I’m planing spruce brace stock for dulcimer backs. The rough brace sits on my planing beam; a flat and straight beam of oak with a bench stop at one end. I use this planing beam when truing and jointing fretboards and fingerboards, thinning bindings, and brace stock. I also use the planing beam as a caul when gluing fingerboards to fretboards.

Yes, it is a fascinating life I lead.

 

The Guitar Maker's Backsaw for Cutting Fret Slots

The overall correct process of placing frets in a guitar fingerboard ("fretting"), is far less straight forward than most people believe. A perfect job, for perfect playability, requires some careful preparation.

Anthony Lintner, guitar maker



Twenty five years ago, I bought my first fretting saw from Luthiers Mercantile. It was made in Germany and had a straight handle on it, basically it was a gent's saw.

First thing I did to the saw was to take off the straight handle and make a nice handle for it from some wonderful Claro walnut that came from a Cottonwood Creek bottom wild grown walnut. I used it to cut fret slots in dulcimer and classical guitar fret boards. The saw served me well for several years until I made the mistake of cutting some brass with it.

Well, I never did get around to sharpening the thing.

The blade is .015 of an inch thick with the teeth set at .022-.023 of an inch. I think it has 22 teeth per inch. It is a great saw and I was very sad to see that the company that made it went out of business a few years after I bought it.

Then I bought a fret saw from StewMac, which turned out to be far less than stellar. The saw blade was exactly .022 inches wide, which meant that the teeth had no set to them making it almost impossible to cut a straight slot in an ebony fretboard. That saw got put in my carpenter's tool box for everyday job site work.

I limped along with the saw from Germany.

Soon, I purchased another fret saw from LMI and once again, no set to the teeth, the blade was .022 inches wide which made life difficult for cutting ebony.

At that point I decided to use the fingerboard fret slotting service that LMI offers, they slot the board and all I had to do was glue the fret board on and use the new fret saw to deepen the slots after I tapered the fret board to final dimensions.



I was never happy with the LMI fret saw even for deepening the fret slots, so one day I broke down and purchased yet another saw from StewMac, this time a Japanese style back saw. It works reasonably well for deepening the slots, though I have to be mindful to always clean sawdust from the teeth gullets with each slot and apply paraffin wax to the teeth to make the saw operate fairly well. I still use the fret slotting services at LMI.

I wish I had a better saw even for cleaning out the slots!

Over a year ago, Kieran, at overthewireless mentioned on his blog that he was working with the folks at Bad Axe Tool Works to make a high end fret saw.

That saw is now available to order. Yep, I will be putting down the $100 non-refundable down payment for a saw.

I am sure that the saw will be worth every penny!

The Joy Of Honing

The joy of honing.A few days ago my finest waterstone shattered. I can’t complain; it had given me over ten years of service and was $30 well spent.

This afternoon a replacement waterstone came in the mail and I took it out for a spin.

I find honing an edge to be a relaxing experience and a form of active meditation. These days I do most of my honing freehand so there are no jigs and gizmos to deal with. I like waterstones because I get a lot of tactile feedback on what is going on between the steel and the stone.

I like feeling two surfaces gradually becoming a single, sharp edge.

A blade becomes sharper and I become more relaxed.

Look, listen and do, but never ask why.

Kenosuke Hayakawa, Japanese wood worker.


Friday is the only day I get to be in the workshop. Due to circumstances beyond my control, I had to take a day job to cover our bills and with this job I have to work four ten hour days, thus Friday is really the only day I get to myself. Weekends are just that, trying to catch up on yard and house work along with having some fun.

Don't worry, by mid-November I will be back in the studio workshop cranking out guitars and capos/cejillas!



My studio workshop is a bit of a mess because I have no proper storage for the likes of fretting tools, sandpaper, wood cauls, etc., etc., many of these things make up an organized chaotic mess on the floor underneath the window, or are cached away in cardboard boxes.

To remedy this situation and help make the studio workshop look like a real studio workshop, on Fridays I have been making two sets of drawers that will support a work surface.

You won't find any dovetails in these drawers, twenty five years ago I discovered that I find cutting squashed triangles a very, very boring task. Rectangles and squares really don't excite me, either. Curves and circles, the shape of a guitar, are much more pleasing to me.

A trim nail gun, a router, a table saw and some glue helped me put this very basic, rough and tumble set together.

The nail holes were filled, now the set awaits primer and paint. I still need to build a base and the work top.




Yesterday, I was able to do some work on a guitar neck that I made about four years ago. It is Spanish cedar with an East Indian rosewood face plate and it is for a guitar with about a 25 5/16" string length or 643mm. When I first made it I tried a different technique for carving the heel, that was using a short knife on a long handle instead of chisels. I almost ruined the neck because of a slip of the knife.

The headstock crest started out in the style of Santos Hernandez, but since I am focusing on making near bench copies of guitars by Hernandez y Aguado, and that there was enough wood left, I cut a HyA style crest. The field between the tuning machine slots will get rabbeted and stippled just like some of the original HyA guitars.

It is nice work to do and a bit of a challenge.



We have had over ten days of thunderstorms and rain here in this part of Colorado, a very soggy start to August. It's been so damp that I had to fire up the furnace! Lots of mushrooms are popping up and in the above photo you can see that the woodland pinedrops are growing at a phenomenal rate! This is less than one week's worth of growth!



This photo shows the saw filer for the Sierra Lumber Company at Lyonsville, California, circa 1900. This was an important job in a logging camp, as you can well imagine, especially for the men who worked as buckers. This photo is from the Digital Collections at CSU Chico.



This flume carried rough cut lumber from the Champion Mill in Lyonsville to a planing mill in Red Bluff, California, a distance of over 30 miles. The flume was abandoned in 1914, this photo shows a crew of men dismantling the flume. I was told that my grandfather, Rufus Wilson, helped dismantle this flume, I like to think that he is somewhere in this photo. Photo from the Digital Collections, CSU Chico.

What’s On The Bench – Filing Frets

In the photograph above are some of the tools I use when filing frets after they are installed on a dulcimer. On this dulcimer the ends of the frets have already been filed flush with the sides of the fingerboard. The next step is to assure there are no high or low frets as these … Continue reading "What’s On The Bench – Filing Frets"
