Luthiery Log - 06 and 07/2019

I’m building a guitar, and logging the progress on the 7th of each month. Here are Months: One, Two , Three, Four and Five.

Trevor told me it would take seven to nine months to build a guitar. I sit here, six months after first walking into his build-shop, with my new guitar firmly in it’s brand new case. It’s done. Finished. I am beyond excited to share it with you.

Session Twenty-Three
Having routed a path for it last time, today was all about securing on the Edging to the Body. This meant the return of the side-bending apparatus so that I could roughly match the contour of the sides again. It was a little more particular this time around, having a small amount of material to bend and a very hot pipe to bend on. Once all the sides were bent, we ran glue along the edge and taped the edging into place. This took the whole night.

Session Twenty-Four
After removing the tape, the edges were grubby with glue and burns from the bending. So this session was all about removing those marks and sanding the edging flush with the body. I was late from work, so I was rushing to get things done tonight. I did manage to grab some before and after shots below. Again it goes to show not to rush. I was using an orbital sander (which i’d never used before) and in not trying to hit the body, I took too much off of the edging where the Neck will meet the body. you can see that it’s the light diagonal bit in the last picture.

Session Twenty-Five
Back in session Eight, we routed a dovetail in the Neck. Today we routed the gap for it to fit into. The gap is a littel deeper than the joint on the Neck, so that if future maintenance is needed a Luthier can drill through the 15th Fret and use steam to soften the glue around the joint. The rest of the session was spent fining up the headstock again after my mathematical mistake. In the picture below you can see the mahogany dowels we used to plug the holes, you can’t see them from the front. Trevor was unsure which terrible film would be selected tonight for his regular movie night: I recommended ‘Black Dynamite’.

Session Twenty-Six
’Black Dynamite’ was a hit. Everyone enjoyed watching it, and I’m sure you will too (if you enjoy a little sillyness, of course). This session was largely about me watching Trevor finish the fretwork on the neck. First I drilled the holes for the Tuners (properly this time) and free-handed a curve at the end. Then Trevor explained every step as he used more and more specialised tools to equalize, curve down, and put softer edges on the frets along the entire neck. He exaplined that this is the one part of the process that he always does, as it has a massive affect on playability and sound. The last picture is all of the metal dust over the neck. We finished the session by gluing the neck to the body.

Session Twenty-Seven
By the time I arrived, Trevor had done some pre-math and figured out exactly where to place the Ebony Bridge, but it was still flat when I arrived. My job was to put the appropriate curve into the Bridge. This was achieved by sticking a piece of sandpaper to the already curved Top and sanding the Bridge against the curve itself. It took a long time. We then created a small cap to glue onto the base on the neck and make it look uniform with the Edging. The Session finished by glueing both of these on.

Session Twenty-Eight
This is the moment that most people had been asking me about for weeks: '“When do you get to oil the guitar?”. The answer is, today. We laid a couple of coats of clear on the headstock, and then I donned gloves and used a small soft metal scrubbing pad to apply the oil. I’ve put a couple of shots below so you can see the contrast of with vs without oil. Trevor said we should be able to finish the project within the next couple of sessions.

Session Twenty-Nine
This was a busy one. We could sense the home stretch, and acted accordingly. I sanded back the headstock and lay down the symbol I had chosen (The Seed of Life). It’s purely black on the Rosewood Headstock, and shines underneath another couple coats of Clear. On the Bridge I drilled and reamed the holes for the Pegs to fit into comfortably. Then Trevor super-glued the electronics for the pickup to my fingers. It was a hard job to position these little golden pads correctly, so difficult that I did it once, then Trevor did it twice. We took a little off an interior brace in order to fit the controller for the pickup, and finished by drilling a big hole in the Bass of the guitar to enable it to plug in, and a matching button near the neck to support a strap. One session to go.

Session Thirty
The Final Session. The birth of my guitar. Trevor was wearing a shirt that I gifted him last week, it has my face on it. This session was all about details. I made a little plate to cover the truss-rod hole in the Head, using a specific drill piece so that the screw used to secure it was more flush with the plate itself. Next was fixing in the Tuners. Using a ruler to make sure they were level, I drilled and screwed them into place. This next bit was super fun, Trevor had glued into place the Nut previously to figure out where the bridge goes, and he had marked the top and bottom string. My job was to find the right spacing between the strings using a specialised ruler, then to file into those marks using specialised files. After I was finished, Trevor took over and worked magic in performing the rest of the initial setup and testing the sound: video below.

While this was going on I watched another student sawing fret-holes. It was surreal to think that six motnhs ago I was doing the same, then I look to the right and Trevor is playing the final product. He’s confident with the sound and hands it to me. I sit and play a newer song, and it’s like a first piece of perfectly cooked steak, the feeling of warm laundry, fresh sheets, a cool water in the summer heat, and a warm mug in the middle of winter. It’s more than all of these things. I’m literally giddy. This is one of my life’s dream and it’s coming true in my hands.

We take a few pictures, and I zip it into a carry case (I pick up a hard travel-case the next day). It’s bittersweet to know that I won’t be coming back next week, but that doesn’t stop me from laughing maniacally all the way home.

Luthiery Log - 05/2019

I’m building a guitar, and logging the progress on the 7th of each month. Here are Months: One, Two , Three, and Four.

So I may have gone a little crazy this month. After coming back from holiday I was itching to get back into Luthiery, and Trevor had more availability, with some students finishing their guitars, and others starting later in the year. So to keep things brief, I’ll combine these sessions into Weekly groups.

Sessions Fourteen, Fifteen and Sixteen
This week was all about the Face and the Neck. We found two short supports for the Face had been positioned badly, and when correctly mirroring the other short supports, they were now too short. Really they had always been too short, but now we had discovered it. Measure, Cut, and Dish the replacement supports, then glue them all into place. Below the X Brace needed a bridge plate to strengthen where the strings will eventually be pulling the top of the guitar, and finally we popped in three small braces to strenthen the sound hole.

We also started marking the Neck to be trimmed down and carved. The main cuts were made on the bandsaw, finishing everything else we could reach with the drum sander. This next part, Trevor said, is his favourite part of guitar building. We put some oil on the Fretboard to bring out it’s natural beauty, before cutting some special wire strips to size and banging them into the neck to create Frets.

Sessions Seventeen and Eighteen
A lot of these sessions went into Carving the Neck. Using a couple of rasps, Trevor would show me how to get the right curve, carve an example patch, and then have me match the curve on the rest of the neck. I was nervous to go too far, and slow to get the hang of this one. I certainly felt better after Trevor confessed he had made seven practice necks before being allowed to touch a real one.

This next part, Trevor said, is his favourite part of guitar building. I used a chisel to pare down the supports under the Face, turning them into real treble-braces and Tone Bars. Trevor showed me how to get very close to the Face without carving into it. During this time I met a couple of other students. Jim was changing professions after a long time serving in the NZ Air Force, so was in Auckland temporarily to learn the craft. He made the beautiful blue electric that you see below. I also met Daniel who was working on a gorgeous Bass, but I neglected to get photos.

Sessions Nineteen and Twenty
This next part, Trevor said, is his favourite part of guitar building. Now that evrything was pared down and sized for the Face and Back, it was time to mark out facets in the Kerfing along the sides. It reminded me of Japanese woodwork, small and intricate. I’m certain that if a Japanese woodmaster saw my work he would call me a barbarian. Neverthe less, we managed to dry-fit the Back onto the sides and were happy with the fit. Before gluing it on, we had to do the same for the top. That way it’s easier to see if which parts needed to be brought in. At the end of session Twenty, we glued the Back onto the sides.

Sessions Twenty-One and Twenty-Two
The first order of business? Glue on the Face. So we did. And it was glorious. Things were going well … a little too well. Next order of business, calculate, mark, and drill the holes for where the Machine Heads, or tuning pegs, would sit in the headstock.

Now I must have been tired that day, because I’m usually good at math.

I added 45 on to 42 and ended up with 97.

It made sense in my head. It looked fine when me marked the placements. It looked fine when we drilled the first hole. The second hole looked great. The third hole was too close. Nope, both the second and third were out by ten millimetres. Solution: Plug the holes with dowels, sand off the face-plate, make a new one. To repeat this work was painful, but a good learning experience to not just measure twice, but to check the math.

This next part, Trevor said, is his favourite part of guitar building. The final session of the month was sanding down the Face and Back until they were flush with the Sides, then routing around the edges to create a track for some lining to be laid on, and strengthen the edges of the body.

Tuesday Tunes & Luthiery Log 04/2019

Tuesday Tunes

“What is this, a cross-over episode?”. Yes. Instead of publishing two blogs on the same day, I have combined them into one, all-powerful mega-blog. Today you get both my (mostly) weekly song recommendation and my guitar building progress. I figure since it’s a guitar centric blog, let’s have a guitar centric song. Also - I have a Gig coming up on the 26th. Check the SHOWS page for the details.

The Song
Song: Sandmonster
Artist: Nick Johnston
Album: In A Locked Room On The Moon - 2013 - No Label
Method of discovery: Spotify Discover 2016

Personal thoughts: I enjoy lyrics. I enjoy the development of ideas they convey. It’s meaningful, then, to recommend a song devoid of lyrics completely. Even ‘Baba Yetu’ has lyrics, albiet in Swahili. It’s so much easier to tell a story with words than an instrument. Where many pure instrumentalist’s pieces tend to strike me as flexing grounds for their chops (I confess ignorance of deeper context), this particular song reminds me of the Hero’s Journey. Nick Johnston seems to possess the ability to state an idea musically, evolve the idea, morph it into something else, and bring it back, changed yet the same.

Theory: Instead of doing only music theory, I’m going to double down on the Hero’s Journey / Monomyth idea by listing parts below (with corresponding Chords). For sake of simplicity I’m going to use Christopher Vogler’s 2007 version. Feel free to listen to the song while reading this and see if you can hear what I hear.

0:00 - Ordinary world (G# - A)
0:16 -
Call to Adventure (G# - A)
0:27 -
Refusal of the Call (C#m - A - E - #A)
0:42 -
Meeting with the Mentor (G# - A)
0:54 -
Crossing the First Threshold (C#m - A - E - #A)
1:09 -
Tests, Allies and Enemies (C#m - A - E - #A)
1:22 -
Approach the Inmost Cave (|:A - D#:|x3 A - G# - B)
1:36 -
The Ordeal (G# - A then D# - E)
2:04 -
Reward (G# - A)
2:18 -
The Road Back (C#m - A - E - #A)
2:30 -
The Resurrection (C#m - A - E - #A)
2:44 -
Return with the Elixir (G# - A)

… or maybe I’m reading too much into it all.

Research: Because I’d like to keep the blog short, and still have guitar stuff to do, I’ve linked a 16 minute documentary that says more than I can about Nick Johnston. Link where the Links are.

Give it a go: If you like the idea of the Monomyth, or if you enjoy guitars

Give it a miss: If you really can’t listen to a song without lyrics.

Luthiery Log 04/2019

I’m building a guitar, and logging the progress on the 7th of each month. Here are Months: One, Two & Three.

Session Twelve
I’m going on Holiday in a few weeks, so I’m wanting to get the most out of my sessions before departing. When the Dish comes out again, I attack the protruding supports with gusto. Or maybe just with my guts-o. In the second picture you’ll notice the previously-glued-in supports over the right hand inside edge, on the other side they’ve already been sanded flush. Then out come the advanced tools; chisels and a plane the size of my thumb. I talk about the tools I’ve purchased and promise to bring in my planes next week so Trover can have a look at them. Then I get stuck into bringing the supports down to size.

Here’s where I make a mistake.

I take the firt two supports down to the size marked on the laminated plans, instead of the revised measurement Trevor provided. They should be 8mm, now they are 6mm. I am genuinely worried, but prepared to re-do some steps, starting with removing the old supports. Trevor says to put it away for now and he’ll spend the next week reflecting on whether or not we need to correct it. I leave the session very emotionally low.

Session Thirteen
It’s been a busy week at work, and I’m nervous to see if we need to fix last week’s mistake. Trevor is quick to put me at ease, it should be plently strong enough, but we won’t do any shaping on those two supports, just in case. I breathe a sigh of relief and get stuck into today’s work, most of which is just like the supports for the Back: Measure, measure again, cut, mark for sanding, sand roughly, finish sanding with the dish, grab the next piece, repeat.

After all is ready, I notch the ‘X’ supports to slot together. We glue it in. We speak about our relationships with our Fathers, and with Religion, and with Tools. Trevor sets up my Number 4 Plane. I finish the night by taking a curved piece of metal and sanding a slight curve into the Fretboard. I don’t finish before Trevor calls time, but I leave much higher than last week.

Luthiery Log - 03/2019

I’m building a guitar, and logging the progress on the 7th of each month. Here are Months: One and Two

Session Nine
We are not alone. Another luthier-in-the-making is in tonight. His name is Chris, and this is not his first guitar build, but the vigor with which he describes his relationship to music doesn’t give you that idea. He’s been to Nashville (a dream destination for myself) and has growing children, each inheriting their father’s music bug. He tells me this while finishing some unknown step on the newest addition to his family (of guitars), which is a lot further along than mine, but is really encouraging to know I’ll be there soon enough. I’m happily gluing in some Lining, or Kerfing, to the inside of the Body, leaving space for some supports to be later glued in. During the session Chris is calibrating the placement of the Bridge, and to get it correct they need to thread on one of the strings and pluck it. Trevor pauses, addressing Chris with gravitas …

“This is the first sound your guitar will make”

It was beautiful.

Session Ten
The session is filled with more Kerfing, this time to the other side of the Body. When we eventually sandwich the Body between the Face and Back, this Kerfing will be what they hold onto. We break the session in the middle to speak about faceplates and symbols. I need to decide which wood to have on the Headstock, and I can choose between Rosewood to match the neck, or Walnut to match the Back and Body. There’s also a choice of what to put on the Headstock, as there’s typically a symbol or brand name up there. We’ve also started talking about bad movies, and how much we enjoy them. I recommend “The Lost Skeleton of Cadavra”, both to Trevor and to you. We end the session by drilling and gluing side-dots into the neck.

Session Eleven
I avoid scoffing at people who name their cars, because I’m one of those people who names their Guitars. I’ve already got a name, which will be revealed at the end of the whole process. But the two weeks since the last Session has been filled with a lot of googling. It’s good that I’ve had a break, because I’m finally able to decide on the symbol that I want on the Headstock. The fact that I want Rosewood was decidedly simpler. When I get in, Trevor celebrates my decisions, noting that he’s not come across the combination of Black Fret-Dots and Rosewood Headstock. I’ve created a monster. But at least it’ll be unique.

Having finished the Kerfing, I glue in side supports and, once dried, attach a small piece of Kerfing overtop to continue the pattern. We also cut to rough size the Rosewood Headstock Faceplate, attaching it to the Head of the Neck.

Luthiery Log - 02/2019

I’m building a guitar, and logging the progress on the 7th of each month. Here is Month: One.

It was strange looking back on the accomplishments of the first month. So strange I went googling for quotes about progress. Most were about social progress, but this one stuck out.

True progress quietly and persistently moves along without notice.     

- St. Francis of Assisi

I’m tempted to put ‘ - Michael Scott’ below. The point is: January started with a decision, and ended with the Face, Back, Sides, Neck, and Fretboard all in recogniseable states. A lot happened, but i never felt like I was doing a lot. Part of the beauty of this course, outlined in part one, is the method Trevor uses. He doesn’t weigh you down with a seemingly endless laundry list of absolutely everything that needs to be done this in every session, including after care instructions. It’s only ever “Let’s focus on doing this job right" and when that job is complete, “Here’s what’s next”. You’ll rarely start a process you can’t finish in the time you’ve booked, which means every night has visible, measureable progress. It’s a great experience.

Session Five
First step is to cut to size some small wood strips, these will become the internal central brace and will strengthen the Back. Once to size, we flex metal rods to hold tension between the underside of the workbench and strips, which are glued ablong the back joint. It' doesn’t take long, and in the meantime Trevor sets a gas torch to heating a metal pipe. I’m mildly worried. But what follows is the coolest part of the process thus far: Side Bending.

The Sides are sprayed with water until soaked, then laid on the heated pipe. As the water evaporates from the wood, the fibres loosen, and you press down on both sides of the pipe to create the curves that form the body. It’s a slower process, and it takes most of the rest of the night. We’re constantly measuring and comparing the sides to the jig, and once it’s pretty much there, we clamp them together and leave it to dry into shape completely. We quickly route the sides of the neck and I retire, ecstatic with the night’s progress.

Session Six
With the Back brace from last week dried, we violently hack into it (with care, diligence and skill) making room for the horizontal braces that will sit perpendicular across the back. There’s a little bit of sizing and measurement, but most of this session is running the pieces across one large slice of sandpaper mounted on a concave dish. This is because the back and front will be slightly ‘dished’ out from the body, instead of perfectly parallel. Trevor assures me it will look normal. This time the flex rods push the Back into that dished shape, as they also apply tension to the glued in horizontal braces. There are a lot more flex rods on this one.

Session Seven
Tonight, I spend a long time sanding the sides. It could be done later, but is easier while the two halves are separate. Now that I’m not power mad by pushing wood into a hot metal pipe, I can see areas where I spent too long making a particular bend. Most of it sands out, so i’m not worried. Besides, according to Keanu Reeves in ‘The Replacements’, “Chicks dig scars”. At some point during this process we talk about how I’m not actually Human, but merely a conglomerate of pop-culture references. We glue the sides together using two blocks that Trevor prepared, and the session is rounded off by drilling some holes in the Fretboard and gluing into position the fret-dots. I’ve chosen black against the lighter Bubinga wood, and I’m happy with how it looks.

Session Eight
Using the ‘dished’ sandpaper from earlier in the blog, we sand the edges of the body, now one piece. This will mean they meet the dished Front and Back properly when it’s all put together. Imagine you have two levers, and as you pull one in, you push the other out. That’s what I’m doing, effectively rotating the sides at the ends. It makes my hips creak and belly jiggle; I’ve never felt more like a washing machine. Trevor calls this ‘doing the dishes’, and as an honorary Dad (eight niblings), I chuckle. To end the month, we put the Neck into a jig, route a dovetail joint in the end and glue the Fretboard to the Neck. Eventually the dovetail will be where the Neck meets the Body, but it’s easier to cut now. And now I may want to buy a router, also.

Luthiery Log - 01/2019

It was a hot day when I met Trevor Binford. I walked up outside his shop (Binford Luthiery) in Onehunga while he was doing some repairs on his car. We didn’t shake hands, his were covered in grease. Inside his shop I described that my steadfast Cort guitar had broken for a second time in the ten years I’d owned it, and although it was repaired, I was looking for a replacement for performances. I’d decided, in a fit of madness, that I would embark on the Guitar Buildshop course, in which Trevor guides you through building your own guitar. So after confirming an appointment, trading emails, and a suitable fistbump, I leave.

It would only be fair to say I was equal parts excited and terrified.

Session One
I turned up after work. We’re alone in the shop. Trevor confirms a few details from the emails we’ve traded, and then tells me his teaching style.
Step One: Describe. Trevor tells you the next step we’re going to take, any machines or material we’ll be using, and some pointers to keep in mind.
Step Two: Demonstrate. He performs the start of the task to give you a good visual indicator of what good technique, and result, looks like.
Step Three: Observe. He’ll watch you do the same.
Step Four: Run Away. Not completely, but once he’s confident in your ability, he’ll go work on some other task (usually a repair for someone else) and leave you to it.
At any point during any step you can ask questions, or double check what you’ve done.
The first task? Choose which two bits of Citka Spruce would become the face. There were four options in stock to choose from, each a bookended pair for symmetry. I learned about the merits of strength versus flexibility, the grain lines of the wood and the effect each would have on the sound. I chose the last pair based on the grain, both for the above and for aesthetic. He applauded my choice and said he would’ve made the same given the same options. Either I’m nailing this, or he has great customer service. We use a machine and a sanding block to square up the insides, then glue the pieces together, holding them all with clamps and weight.
Then he busts out some Bubinga which will become my future fretboard, and a crazy jig and reference board. We begin cutting holes for frets, which takes the rest of the session as we listen to Jonothan Coulton (my choice). I leave, less terrified, more excited.

Session Two
My Sides and Back have come in, and the Face is dry. There’s another person in tonight, sanding down their Neck. But before we get to that, more Fretholes required. I finish the fretboard, and we repeat the steps from last week for the Back. I decide to keep the white stripe in the Back, it’s not glue, it’s the heart of the Walnut tree that provided the wood. It’s left to set and we take the Face to the bandsaw. I sweat bullets as I’m cutting out the shape of my guitar, particularly around the cutway (not a standard option that Trevor offers, as it’s a bit more finnicky). I don’t lose any fingers.
The Neck follows. One solid piece of Mahogany that we cut at an angle to create the Head. A few more lops from the other end to create the part of the Neck that meets the Body. and the session finishes with a bit of sanding before the Neck pieces can be glued up.

Session Three
We’re alone again. The Back is dry, and is quickly cut out on the bandsaw. I now have a definite inside and outside surface on both the front and back. More importantly, I still have all eleven fingers. The joint surfaces on the Neck are sanded and glued, then stapled together, just to show it we mean business. During sanding we listen to Warren Zevon (Trevor’s Choice) and he is surprised when I recognise the singer. We become best friends (his words) over the lyrics and subtle guitar lines. Then we route the space for the Rosette, lay the Rosette, and route the Soundhole, all in the Face. He says we’re making really good progress.

Session Four
The Neck is dry, so I use a chisel to zip off the excess before running it through a series of machines to square up the sides and faces. Then we set up a router and bore into the solid, rich Mahogany to make room for the Truss Rod, the part which can bend the neck forward and backward to help control the Action over the Frets. The rest of the session is to use a thicknesser to lower the thickness (weirdly) of the Face, Back and both Sides. It’s a long process, and only toward the end do we realise there is no music. I become an annoying Millennial by grabbing a few last photos before ending my first month in the shop: One of all of the parts laid out, another of the parts in the cupboard below a more finished project.
The last depicts two madmen: one who decided this was a good idea, and the other who decided the same, except full time.
