Keepsake box: the frames and panels

Guitar Building By Hand - Tue, 11/25/2014 - 8:46am

I started the box by making the top and bottom frame and panel, mainly because this was new territory and I wanted to keep my options open. I figured that I could fit the rest of the box to the frame and panels if they ended up being slightly off in size.

I completely blew the first mortise by chopping right through the frame with my chisel. This was caused by a combination of laying out too deep a mortise and hitting the chisel too hard while chopping. Luckily I had some extra wood, So I redrew the mortises slightly less deep and hit the chisel with more care, especially when reaching the bottom of the mortise.

After making the frames, I measured and cut the panels to size. I bevelled the outside and rebated the inside of the panels.

I was quite pleased with the end result. The frames were square and the panels fit!

Stanley No. 45 Combination Plane, Type 7B, 1901-1906

Brokeoff Mountain Luthierie - Mon, 11/24/2014 - 12:07pm
The craftsman in wood may ask himself "Why should I possess a Multi-Plane?"

Hampton and Clifford, Planecraft, 1934




I splurged the other day and ordered a No.45 plane from one of my favorite antique tool dealers, Sydnas Sloot.



I've always wanted a No.45, but I never could find one at an affordable price and then the other day there was this beauty on Sandy Moss's website. I couldn't resist. Thanks, Sandy!



It doesn't have all the bells and whistles that come with some of the 45's, I figure I can buy extra blades and soles as I find them.




The box no longer has its sliding lid, I can live with that, perhaps one of these days I may make one and repair the box.

I love this box for the decal, the box is cool enough to use to hold just high dollar guitar tuning machines...




It has all the parts I need, in the next few weeks I will use this plane to cut drawer grooves. I could use it for sash work, but I'd have to find or make a blade for an ogee, I'm not too partial to ovolos on the muntins, rails and stiles of a sash.




The instruction sheets.

For more information on how to use these beasts click here for the Cornish Workshop and here for a pdf copy of a Stanley No.45 instruction booklet.

I will definitely read through Alf's (Cornish Workshop) tutorial on how to tune and use a No.45.


The UPS driver just arrived with Spanish cedar neck blanks for two of the guitars that I will be making this winter.

It's snowing outside at the moment, guess I had better get back to work...

Disston Rip Saw, Stanley Scrub Plane, Douglas Fir Guitar Top

Brokeoff Mountain Luthierie - Mon, 11/17/2014 - 3:47pm
Towering up to heights as great as 220 feet, with sometimes 100 feet of trunk clean of branches, arrow straight, and with almost no taper below the crown discernible to the naked eye, an ancient Douglastree may be 17 feet in diameter.

Donald Culross Peattie, A Natural History of Western Trees, 1953



Douglas fir isn't often used as tonewood for classical guitars, many makers think that it is too heavy of a wood to be used for guitar tops. The strength of Douglas fir is phenomenally strong, its specific gravity is 0.50 and its modulus of elasticity is 1.95! Compare that to Sitka spruce's specific gravity of 0.42 and its modulus of elasticity at 1.57.

I think it is great wood, and, yes, I am biased because I was weaned on a chunk of Douglas fir, it was a playmate along with ponderosa and sugar pines, incense cedar and black oak.

The point of all this is there is a young classical guitarist who wants me to make him a guitar with a Douglas fir top.



This is the last piece of old growth Douglas fir that I possess, it was salvaged from old bleachers and I acquired it from a trim carpenter who was making doors out of this stuff.

Just think of all the butts that sat on this wood...




Ripping it down with my trusty No. 7 Disston rip saw...




To the saw horse for the last few inches...




One problem with ripping out tops from a piece of wood that is under an inch in thickness is you don't always get to rip out two sets of tops. I suppose if I owned a real he-man Norm-ite 10 ton style re-saw bandsaw this wouldn't be an issue, but I enjoy the gentle noise of a hand saw.

To make sure that I end up with two pieces that are 5/32" to 3/16" of an inch thick, I reached for the No. 40 Stanley scrub plane.

Running this plane over and through the wood I can get a sense of the sound, the voice, this guitar top will have. I just listen to the blade cut the wood and I hear music...





The top after is has been smoothed with a No. 3 Stanley plane.

I have drawn the plantilla, or outline, that is based on one created by Manuel Hernandez and Victoriano Aguado, in 1961.




The grain on this piece of wood varies from 15 rings per inch to 32 rings per inch.

Very beautiful wood.

I can't wait to start working on this guitar...

Keepsake box: the six P’s

Guitar Building By Hand - Mon, 11/17/2014 - 8:51am

My father in law used to always quote the six P’s: Prior Preparation Prevents Piss Poor Performance. Very wise words, to be heeded at all times! Especially when making furniture.

I spent a lot of time thinking about the box before I even started. A lot of time. Too much time? I don’t know. Looking back, I think the time I took was worth it. It was the first time I was tackling a project of this complexity on my own. Although I was adapting an existing design, I had to rethink not only the external dimensions but also the joinery (tenon sizes, dovetail layout, etc). Since this was an important gift I wanted it to look really good, and didn’t want to mess up (that should apply to all projects, but still, this one was different!).

I tried a few things to get the dimensions to where I wanted. I tried scaling the original design. However, this didn’t really work: I wanted a box that had a shorter width and length than the original, but still had some height. It had to be of a practical size so you could still use it to put things in. One practical consideration was that the wood had already been sawn into planks, so I had a fixed wood thickness to consider in relation to the size of the box.

After doing a lot of thinking in my head and some sketching, I delved into the world of the Golden Ratio. This did help me get some ballpark ratio’s, like the ratio of the drawer height to the rest of the box. But it became a slippery slope towards being over complicated and fussy for my liking. I also tried using Sketchup. Although I’m quite computer literate and it gets rave reviews, I can’t connect with it. It took me hours to just draw a box with a flat lid. I’m not sure I’ll be using that again.

What helped me the most was simply drawing on paper. First I made some scale drawings. I thought about how deep the inside of the box and the drawer would be and if these were practical dimensions. I sketched on the wood itself to see how the grain would look once it was sawn to size.

But what helped me the most was making life sized drawings. I drew each side of the box on a large sheet of plywood. After some resizing/redrawing I got what I wanted. I also penciled in the joinery – the mortise depths, the frame and panels the dovetail layout etc. Penciling in the joinery was very helpful, not only during the design phase but also during construction and assembly. I really recommend drawing out the joinery, especially when building something for the first time. It helps as a reference and also helps think the project through before you start marking out and sawing bits of wood.

I felt comfortable with the design and felt I had taken care of the five P’s. Time to start building!

How to Make a Box Sing, Part 2

Brokeoff Mountain Luthierie - Mon, 11/17/2014 - 7:13am
Here is a video of Kyle Throw playing the Torres/Santos style guitar that I finished this summer. The guitar has a Engelmann spruce top with California laurel back and sides, 650mm string length.

This guitar is very responsive, very loud and is capable of many musical nuances, with proper playing and care it will continue to improve and become a magnificent guitar!

Kyle performs the Fandanguillo from the Suite Castellana by Federico Moreno Torroba.

Keepsake box

Guitar Building By Hand - Sat, 11/15/2014 - 11:40am

I wrote my last blog post in May: eek!

I’ve been spending as much time as I can in the workshop and have completed a few projects since my last post: a keepsake box, an ebony chopping board and a corner cupboard. Plus some other things in between.

I’m going to start with the keepsake box. I’ve prepared a few posts about it, which I’ll be publishing over the next week or so.

The keepsake box was for my little nephew, who was born in January this year. A few months before he was born I obtained a nice piece of Dutch Elm for this project. I really like elm. It’s got a varied texture, a deep reddish colour and is nice to work with.

The design of the box was inspired by Paul Sellers’ tool chest on Woodworking Masterclasses. You can read about his tool chest here. My plan was to make a smaller version, with just one drawer.

There are many cool features in this chest which I wanted to try out. For one, it’s got a frame and panel top and bottom – a technique I hadn’t applied until now. Another feature is the lid, which is made by first making the box, fixing the top and bottom and then sawing the box in two. Very scary prospect, but I wanted to try this as well. And third, the drawer. This would be my first ever drawer, so that was also something to look forward to and of course a necessary skill to master.

Anyway, here’s a sneak peak of the end result. I’ll use the next few blogs to document the highlights and share what I learned along the way. Hope you enjoy!

How to Make a Box Sing

Brokeoff Mountain Luthierie - Tue, 11/11/2014 - 12:54pm
Stephen Valeriano and Kyle Throw, both classical guitar students at Metropolitan State University, Denver, stopped by my shop last weekend to play two guitars that I have on hand. Kyle also came by to pick out the wood for the new guitar that I will be making for him over the winter.

Stephen played Heitor Villa-Lobos' Prelude No. 1 in e minor on a Sitka spruce/black walnut guitar that I made a while ago.

He does a wonderful job with this piece, he is a very sensitive musician and I expect great things from him.

Enjoy!

1860's Greek Revival House: My Work Is Done!

Brokeoff Mountain Luthierie - Tue, 11/11/2014 - 12:05pm
Greek Revival A style popular in the first half of the nineteenth century, it favored the Greek version of Classicism over the Roman. This meant eschewing arches in favor of post and lintel, basing forms on the Greek temple, and using the Greek version of the Orders.

Mark Gelernter, A History of American Architecture, 1999



Two weeks ago, I and my co-worker, Michael Lohr, were able to walk away from the 1860's era Greek Revival farm house that we worked on all summer.

Siding was replaced, a new door matching an original was added, several days were spent in a skid steer landscaping the grounds, and paint was applied to the building.




Here is what the house looked like when I started working on the building...




Siding and landscaping completed...

Hernandez y Aguado Style Guitar, Douglas Fir Top, Mahogany Back and Sides, SOLD!

Brokeoff Mountain Luthierie - Mon, 11/03/2014 - 8:58am
The classic guitar is a delicate equation painstakingly conceived to produce a brilliant, balanced tone over its entire playable range.

Irving Sloane, Classic Guitar Construction, 1966


The young guitar student that I mentioned in my last post came to my shop yesterday to take delivery on the Douglas fir/mahogany guitar. It is a close copy of a guitar made in 1968 by the great Spanish makers, Manuel Hernandez and Victoriano Aguado.




The top is from a salvaged Douglas fir board...





...and the back and sides are Honduran mahogany.


The young man played several Catalan songs arranged by Miguel Llobet, I thought I was listening to an old recording of Andres Segovia! This guitar has an old Spanish-like quality to it that gave me goose bumps, it sounds so wonderful! I can't wait to hear this guitar in six months!

I hope to get a chance to record the young man and his guitar this winter so I can post the videos on this blog.




He and his father gave me a deposit so I can start working on another guitar for him.

He really likes the Douglas fir for its sound, now I need to convince him to let me use sustainable woods that grow here in North America for the rest of the guitar...

The Best Wood, Part 2

Brokeoff Mountain Luthierie - Mon, 10/27/2014 - 10:58am
Federico Sheppard: Do you ever use cedar tops?

Antonio Marin: Yes, but only two or three per year. This is a spruce town.


From an interview with the great Granada guitar maker, Antonio Marin, American Lutherie #117



A young man visited my studio the other day to chose a guitar from my inventory, he was looking to replace the Asturias brand guitar that he is currently playing. His two complaints about the Asturias were the string length (656mm) and the neck is too thick and rounded.



Spruce/Walnut Guitar


I handed him a spruce/walnut guitar (photo above) with a scale length of 650mm. He loved the neck and the string length, but I noticed right away that he was struggling to get a good sound out of it.




Spruce/California Laurel guitar, Torres/Santos Model

So, I pulled out one of my latest guitars, the one based upon Antonio Torres's guitar FE 19, which is loud, has an amazing voice and capable of many nuances and again, as he played this guitar I noticed that he didn't get along with it.

"Wilson," he said, "I really want to play that Douglas fir/mahogany guitar that you brought to the Guitar Celebration at Metro State."





I got that guitar out of its case and handed it to him.

It was startling to hear him play that guitar, it was clear that a spruce topped guitar was not for him. The piece of music that he played was immediately clearer in sound and quality, no flubs with the left or right hand.

This guitar has a 640mm string length, one-half inch shorter then his Asturias, which he noticed right away and mentioned that the neck on my guitar made it easier from him to play.

For a little experiment, I let him play my old battle axe, a cedar top Hernandis guitar with a 665mm string length that was made in Japan in 1973 and imported by Sherry-Brener, the one that I played at the Christopher Parkening master class (click here for my posting on that) all those years ago. Yep, he could play that guitar well and it turned out that his Asturias guitar has a cedar top.

I told him that at this point in his studies he is a Douglas fir and cedar man.

I never would have thought that wood could influence a classical guitar player that much.




A true Spanish guitar is made of spruce and rosewood, like the woods in the photo above. I strive to make as Spanish of a guitar that I can, even though I am not Spanish, I want to capture that sound I heard in Segovia's and Sabicas' recording when I was studying the classical guitar.

Working with these young musicians is showing me that I need to make instruments that fit them, that fit them physically, sonically and dare I say it, emotionally. The guitar they play should blow their minds so much that they can't stop playing it and through that constant playing they become better musicians. That is a goal worth working for.

The young man will come back next weekend to pay for and take delivery on the Douglas fir/mahogany guitar. He mentioned to me that he wants me to make him a guitar for his senior recital, which will be in one year.

I all ready know what woods I will use for that guitar: a Douglas fir top; black walnut back and sides; walnut for the neck; black locust for the fret board and bridge; and braced with Engelmann spruce.

All woods that grow in Colorado.


Douglas fir that was salvaged from an old bleacher seat. I've had this piece for 15 years

Time for me to go have lunch and get into the workshop and do some work!

Wooden Straight Edges

Brokeoff Mountain Luthierie - Mon, 10/20/2014 - 4:57pm
It is not advisable and can even be dangerous, to entrust someone else with the search for a fiancee, the purchase of a pair of shoes or the choice of a guitar.

Jose Ramirez III, Things about the Guitar, 1990




I didn't get everything done today that I wanted to get done, but I did get started on a few things.

After morning chores, I took the dogs for a walk through our wonderful backyard, which is part of Arapahoe National Forest, and then started making legs for a router table. I have about ten windows (6-9 pane) to make before the end of December and I am not about to plane all the muntins, rails and stiles by hand, I have an expensive router bit for that.

I got the legs glued up, went for a 2.5 mile run and had lunch. The afternoon, I thought, was going to be dedicated to working on a copy of a 1968 Hernandez y Aguado classical guitar, click here for a post on that guitar, I need to thickness the fret board and glue it onto the neck.

First thing I wanted to do was to check to make sure the gluing surface of the neck was still straight, and, as usual, I once again discovered that my 24 inch long Lee Valley straight edge is too long to check the neck. One end of the straight edge ends up on the guitar body which has dome to it so the straight edge won't sit flat. Duh.



The answer was to make a straight edge. If you don't already have Chris Schwarz's article on how to make such a beast, click here and take a gander at how to make a wooden straight edge.

I wanted to use some mahogany that I have, but it isn't quartered well enough. Once again, it was California laurel to the rescue.





The straight edge that I needed most was this one - 16 inches long to check where the fret board will sit. I should have made it 17 to 17 1/2 inches long.





I had a 10 inch piece left over which will be perfect for checking the other side of the neck.





I love California laurel, I wish had some more. It has a wonderful smell, is very easy to work with and makes incredible sounding guitars. I suppose I ought to order a few laurel boards from Gilmer Wood or Northwest Timber.

The fret board will have to wait until next weekend, tomorrow is back to work at my day job.

Advice for an Aspiring Classical Guitar Maker

Brokeoff Mountain Luthierie - Sat, 10/18/2014 - 5:13pm
I shall start off by stating something that could sound rather surprising coming from a guitar maker: a guitar is not a work of art - it is almost fundamentally a technical opus.

Jose Ramirez III, Things About the Guitar, 1990


The following advice is for those who want to make a classical guitar in the Spanish tradition. I do not make steel string guitars, I am not interested in them, but, perhaps, some of this advice can be used to help you succeed in making a steel string guitar.



#1: Buy the following books:

Guitarmaking: Tradition and Technology, by Cumpiano and Natelson, click here;

Making Master Guitars, by Roy Courtnall, click here;

The Guitar Maker's Workshop, by Rik Middleton, click here.

And you must buy every book written by Roy Underhill. You will learn so much about hand tools from him!

Read them from cover to cover several times before you start to make a guitar or buy any tools.





#2: Buy The Naked Woodworker with Mike Siemsen (click here).

Buy all the tools needed to build his version of Nicholson's work bench. This DVD will also help you when you go to purchase other tools for guitar making. Remember, you will need a work bench on which to build your first, second, third, etc., guitar!

This DVD is another "must" for your education!





#3: Keep the tool list simple.

Buy only what you need.

Stick with hand tools for your first guitar or two, hand tools are much quieter than power tools, but can bite as badly.

Safety should always be your first concern.

Click here to read about my list of tools for guitar making.





#4: Pick a guitar to make.

Click here to see some plans that are available from the Guild of American Luthiers.

I suggest that you make the guitar in Guitarmaking for your first guitar.

Do not deviate from the instructions in the book, you can do that on your second or third guitar.

Or you can pick a historic guitar, such as the 1912 Manuel Ramirez guitar that was used by the great Andres Segovia (click here for a video), and use the instructions in Courtnall's book to build it, but no matter which method you chose you must follow the method to the letter and remain true to whatever guitar you pick!





#5: Here is where I am going to get into trouble from the cyber wood working world.

Do not visit any forum on guitar making!

Forums are a waste of time, you should be in your shop making a guitar.

Do your own research on guitar making! Read every thing you can get your hands on and then spend time in the shop working on guitars!

Many would be guitar makers express their opinions on guitar making in those forums and that is just what they are - opinions. Then the professionals weigh in and it gets messy.

Remember this: your goal to is make a guitar that a guitar player will play and use. Very few professional guitar makers are professional musicians.


Tico Vogt playing one of my guitars




#6: After you have made two or three guitars start researching how the traditional Spanish guitar was/is made. Or maybe you will buy into the school of making where every guitar should have a double top with lattice bracing.





#7: When you have completed your first guitar, do not take it to a professional guitar maker for a critique! A guitar maker will not buy your guitar, only a guitar player will buy your guitar!

Players/performers are the ones who will tell you if the action is too high, if the guitar is too quiet or too boomy, they are your best critics!





#8: Perhaps the best piece of advice I can pass along is produce, produce, produce.





#9: You can ignore what I just said and hie yourself to the nearest guitar making school.

I know that Red Rocks Community College in Lakewood, Colorado has a great program, click here to learn more. I know that there are other such programs through out the nation.

One reader told me that he was able to find a guitar maker who was willing to teach him how to make a guitar, that is another great avenue to proceed on!

Better yet, get a grant so you can go to Granada, Spain and study with Antonio Marin or John Ray or Antonio Raya Pardo! Learn how to make a truly Spanish guitar!

A guitar is a romantic creation.





#10: You must live, eat and breathe classical guitars! That means you must love them and that is all you want to make! Money should be of no concern to you, think not of making a living at making guitars! The only thing that matters is that you make them!






#11: If it were easy then everyone would be making guitars...




Now, turn off your computer or other device and get yourself into the work shop and make something!


Here is a wonderful phenom, Leonora Spangenberger. She is only 11 years old!

Factory Fiddle Scroll

Owyhee Mountain Fiddle Shop - Thu, 10/16/2014 - 2:28pm

Nothing special about this.  It's a typical ca. 1900 "factory fiddle", probably from Germany.  Labelled "Antonius Stradiuarius ... 1736".

I liked seeing the facets.  Hastily carved, by someone who had carved a few, and was just trying to make a living.  After that, the scroll itself has seen some use over the years.

Interesting character, I'd say.

1964 Jazzmaster fret marker repair and refret

James Roadman Instrument Repair - Sat, 10/11/2014 - 7:36pm

This  neck came off a 1964 Jazzmaster that was heavily modified and adorned with ornaments.  The fret markes had been gouged out leaving odd shaped jagged holes and the fretboard was worn, pitted, and scarred from some terrible fretwork.  The veneered fretboard left very little material to work with.  To clean up the fret markers I was able to drill holes with a flat bottom drill and plug them with matching rosewood plugs.  Afterwards I drilled the correct size marker holes and installed clay dots.  Since the wood beneath the frets was still the original height I was able to level the board just enough to true these ridges for the new frets to be installed.  There are still areas of wear and gouging between the frets but they all sit level and it plays very well.

Made a Draw Down Stand for Saddle Making

Brokeoff Mountain Luthierie - Thu, 10/09/2014 - 9:02am
The one piece of equipment that is almost indispensable is the drawdown stand.

Lee M. Rice, How to Make a Western Saddle, 1953



I recently attend a local heritage days celebration, there were many great volunteers on site who did a great job of engaging the kids in butter churning, quilt making and several other skills.

I did notice a volunteer who was trying to teach two young boys how to rope, the volunteer couldn't handle a rope any better than the boys, he just handed them the ropes and walked away.

I went over and showed the boys how to build a loop, how to hold the loop and rope coil and how to catch a calf with a simple under hand throw. Then I showed how to swing the rope over head - one boy caught on and roped the dummy calf, he was very excited. On the way home I told my wife that I should volunteer next year and be the cowboy.

Horses were always a big part of my life, I rode whenever I had a chance and my brother and I occasionally got the chance to ride for one of our uncles who owned a large ranch and ran about 500 cows. We could rope and ride with the best of them, but back then (1980) the best wages I could get was only $600 a month with no benefits. So, I went to college.

The day after the celebration, I found an old slick fork saddle at a local antique store for a decent price. My idea is to fix it up enough to use it as a prop for my 1880's cowboy living history program. Though to even start the necessary repairs, the first thing I need is a way to hold the saddle so I can work on it.



The stand is pretty much the one that Mr. Rice describes in his essay, "How to Make a Western Saddle", you can find it in the book How to Make Cowboy Horse Gear, by Bruce Grant.

I used some piss fir (white fir, abies concolor) construction lumber that I had on hand to make most of the parts.

The slot that you see in the leg is to accommodate a 2x4 that is hinged to the back leg. In turn a short board is bolted at right angles to the 2x4 to which you attach a 36 inch long strap of leather that goes from the cross piece over the saddle to the other end of the cross piece. You then put your foot on the 2x4 and push down to tighten the leather. You have to figure out a means to hold the 2x4 in place.





It's a simple stand and for something like this, I used power tools to make it, I had other chores to get done the day I made it.





Here's the saddle I bought.

There is no maker mark on it, all I could find was "Warranted Steel Tree" and the number 077. After a little research on-line, I came to the conclusion that is was made for either Sears and Roebuck or Montgomery Ward, and was probably made between 1905-1915.

It has a seven inch wide fork, a fifteen inch seat (a little short for me), double rig (a "rimfire") with a five inch cantle and it's in fairly poor condition. I suspected that the cantle was broken when I bought it, that was confirmed when I got it home. This isn't too big of a deal, once the saddle is down to the bare tree, I'll strip the rawhide covering off the tree, repair the cantle and recover the tree with fiberglass and epoxy. I know that that is a lot of work to do on a saddle that is not collectible, but some one used this saddle hard and liked it well enough to have had some repair work down on it.





It'll be a side hobby this winter, I will need some time away from guitar making!

What’s On The Bench – 10/7/2014

Wood sides for a Korg Delta

James Roadman Instrument Repair - Thu, 10/02/2014 - 8:42pm

One of the sides of this Korg Delta was cracked and the owner asked me to make wooden replacements.  This seemingly simple task turned out to have quite a few challenges.

The brackets that attach to the sides are recessed, at different depths no less.

I used the router table to make a duplicate of the ends. I only needed one template because the ends are mirror images.  I used and oversized bearing on a router bit to enlarge the ends by about .100″ just to give the edges a little thickness. I then used the center finder on the milling machine to locate and drill the holes for mounting the brackets.

I measured the depth of the different slots and used the milling machine to accurately rout them to depth.  With a little adjustment with a chisel I was able to get them to fit tightly in the recesses.

After a little sanding and several coats of Tung Oil I assembled all of the pieces with button head socket screws and installed them on the keyboard.
