Double Top Classical Guitar - Redwood/Nomex/Sitka Spruce/Curly Black Walnut, Part 1

In an earlier post, I talked about how I replaced the top of a guitar I had on hand with an all-wood double top as an experiment. The new top was an improvement, it was very loud and strong, but its voice, to my ears and aesthetic, was lacking in beauty. I mentioned this in a text to a guitar maker I know in Brazil, he replied that he had made a similar double top and found that it "lacked resonance".  After playing the guitar for several weeks I made the decision to replace the top yet again, but this time with a “standard” double top that has a honeycomb Nomex core. The top is redwood and the inner veneer is Sitka spruce. Here is a link for more information on double top guitars.

Here is a jig I made from MDF, I wanted to have the main area of the lower bout to carry the Nomex. At this point the entire top is about 2.7mm thick. The top is on a vacuum platen that I made, the air is removed with a shop vacuum, this way the top won’t move or get pulled up into the router bit.

The feeler gauges in front of the jig represent the final thickness of the routed area, about 0.7mm.

Here is the top after routing.

The jig then goes on top of the honeycomb Nomex material…

and I careful cut the material with a chisel.

The honeycomb material was glued onto the top using a polyurethane glue and a Roarockit vacuum bag.

I used Sitka spruce veneer to cover the Nomex and redwood top. After the glue has set, I sanded down the honeycomb material level with the top, graduated the top so that after I glued on the Sitka spruce veneer I could graduate the thickness of the tops edges to about 2.0mm, the area under the bridge to about 2.5mm and most of the upper bout to about 2.7mm.

I went with a different bracing pattern this time, it is loosely based on bracing pattern used by a guitar maker in Granada, Spain, whose guitars I greatly admire.

Stay tuned for part 2, when I will share how I put the guitar back together!

Building an 1830's René Lacôte "Legnani Model" Guitar

I made this little guitar about ten years ago, it is based upon an original 1830's "Legnani Model" guitar made in the René Lacôte Paris workshop. Luigi Legnani was a popular European guitar virtuoso and composer in the 1800's, both René Lacôte and Johann Stauffer made guitars for Legnani to his specifications. My little guitar started out with a Douglas fir top, California laurel back and sides, with a simple bridge made from a block of East Indian rosewood. When I glued the bridge on I discovered that I had the angle of the neck set wrong, the bridge ended up being way too tall for the guitar and the Douglas fir top was too thick and heavy to produce a decent tone, it sounded like it was being played underwater. I put the guitar into a case and tucked it away.

December of 2020 I pulled it out from the closet so I could practice on it, I had a full size classical guitar in the shop that needed a new top, and I wanted to try a new way of removing guitar tops.

Here's the guitar before the removal work started.

The fret board and neck came off... I could rout out the perimeter of the top and save the original binding.


Here it is when the top was first removed...

...and all the bracing removed.

I used an nice piece of European spruce for the new top...

...and I did a good job of routing that saved the curly maple binding I originally used.

I believe the original Lacôte guitar had "ladder bracing", simple braces glued to the top that were parallel to the guitar bridge. I wanted to make this guitar as attractive as possible to today's young guitarists, and what many want today is loud guitar that is responsive and capable of many musical nuances. To that end I used a simple 3 strut "fan" bracing. This style of bracing was developed by guitar makers in Spain who were contemporaries of Lacôte, C.F. Martin used it on many of early guitars soon after his arrival in the United States in 1833. 

These simple braces allowed me to slightly dome the guitar top to give it more structural integrity and lyrical voice. The strip of ebony is there to reinforce and protect the top from the bridge string pins.

The top was glued onto the sides...

...and I made a new neck from Spanish cedar. The v-joint was used by many European makers at the time to attach the neck to the body, it is still used by steel string guitar makers and some classical guitar makers.

Unlike the original Lacôte guitar, this guitar has a raised fret board, the original guitar's fret board was level with the guitar top and the 12th through 22nd frets were directly inlaid on the top. I chose a raised fret board and extension to attract today's player.


The bridge is very similar to the original...

...even down to the end pins and Mother of Pearl dots!

All strung up! I need to French polish the guitar now!

The back and sides are California laurel, or Oregon myrtle if you live in Oregon, I re-sawed this by hand with a Disston rip saw from a board I purchased from a wood supplier north of Eureka, California.

I kept the "ice cream cone" heel on the new neck...

...though the head stock is slotted to receive modern tuning machines, the original had a solid head stock with mechanical tuning pegs.

This is a lovely little guitar, the string length is only 595mm, but it has a wonderful voice and how loud it is will surprise you!

All Wood Double Top Classical Guitar

 Double top, or composite top, classical guitars are all the rage these days, especially among young guitarists and I decided that I would make a double top guitar. Instead of using Nomex honeycomb material as part of the composite top, I used a router to rout out channels in the top to help reduce the top's weight. I got this idea from the wonderful guitar maker, Steve Ganz, using his technique requires minimal tools and no vacuum platen to hold the top down while routing.

I saw no point in building a completely new guitar, so I took the top off of one of my guitars to conduct this experiment.

I then made the channel top...

...glued redwood veneer over the channels...

...braced the new top with my standard bracing...

and proceeded putting the guitar back together.

I put strings on it two days ago and with the cedar top is definitely louder than it was with the redwood top. Next week a friend of mine is stopping by the shop and I am going to get him to try out this guitar and get his opinion.

The point of making a composite top is to decrease the weight and improve the stiffness of the top. This top finished out around 2.6mm thick, most my normal tops finish out at 2.0mm thick, and was 15% lighter than a 2.0mm top. That means it is considerably lighter than a solid top of the same thickness!

I definitely want to try this technique again, but start from scratch and use East Indian rosewood for the back and sides.

My Latest Guitar

Those of you who follow my blog may know that I am a sponsor of the Twisted Spruce Music Foundation Symposium and Competition, this symposium brings together composers and young guitarists to create new repertoire for the classical guitar. Again, I am donating to the Foundation a high end handcrafted classical guitar which will be presented to the winner of their 2021 Classical Guitar competition.

This guitar's top is salvaged old growth redwood, the back and sides are East Indian rosewood that was milled in Milan, Italy twenty years ago, the neck is Honduran mahogany with a Macassar ebony fretboard, its string/scale length is 648mm/25.5inches, it sports Waverly Sloane tuning machines, the bindings are double thick ebony and the bridge is East Indian rosewood.

I just started French polishing the guitar with blonde shellac and expect to have it completed by mid October.

My young friend, Gwenyth, who is currently studying classical guitar with Manuel Barrueco at the Peabody Institute, was kind enough to stop by my study and try out this guitar while it was still "in the white". It is always a delight to hear Gwenyth play! She played on this guitar for nearly two hours and said, " I congratulate the guitarist who wins this! It is an amazing guitar!" It has a wonderful voice, it is loud with wonderful projection with incredibly clear treble strings, and is very even across all strings! This guitar will continue to improve and grow as it is played! I posted another video of Gwenyth on social media and got a wonderful response from Laura Husbands (adjunct faculty of Guitar at the Lamont School of Music, University of Denver), she said, "What a beautiful guitar!"

Here is a short video of Gwenyth and my latest guitar! Enjoy!

Classical Guitar Festival Experiences, Part 2

“Is that who I think it is?” I asked Frank as one of the vendors walked by his table.

“Yes, it is.” he replied.

“I should go over to their table and try out one of their guitars.”

“They make double tops” Frank said with some disdain. He continued to play my guitar, I kept quiet and avoided that table all week.

Frank then launched into “Muneira”, the finale of Federico Mompou’s Suite Compostelana, his playing was furious and wonderful, I had no problem hearing the guitar in the cacophony of other guitarists playing other vendor guitars in hopes of finding one that was truly great. 

When Frank finish the piece, he looked up, smiled at me and proclaimed, “I could play a full concert on this guitar tonight!”

“Well, why don’t you?”

“The powers-that-be do not seem to think I am fit enough to be on the marquee!”

Later that afternoon, Frank began to sing, his assistant accompanied him on a guitar and a hush fell over the entire space as everyone listened to his wonderful voice.

What a Concert Classical Guitarist Says About My Guitars

 I have had the pleasure of playing the magnificent guitars made by the luthier Wilson Burnham. The first impression that one perceives is the beautiful and fine aesthetics of his meticulous craftsmanship, but the most important thing for a concert guitarist is to be able to reveal all the expression, dynamics and musicianship that only the fine instruments can offer us and  without a doubt that is what we find in Wilson’s guitars: balance, elegance, color, volume, dynamics and a fast response, a sound that flies, catches and embraces not only the player but also the audience. An ideal guitar for the professional soloist and also for the serious student. Highly recommended!

Classical Guitar Festival Experiences , Part 1

A couple years back, I was a vendor at an international guitar festival and in the first minutes of the opening day a gentleman approached my table and began looking at two western red cedar/East Indian rosewood guitar I had made. He complimented how they looked, then took one from its stand and played it. After several minutes of playing he tried the other cedar topped guitar and when he was finished with that one he asked me for prices, I told him that both were $3000. His eyes got big and asked “Really?” He returned the guitar to its stand and said, “I will be back!” Fifteen minutes later he returned with a friend and I immediately recognized his friend who was well known East coast classical guitar maker. The friend didn’t introduce himself and made no attempt to acknowledge my existence, and sat down opposite the gentleman who was already playing the first guitar he tried. 
“What do you think?”, the gentleman asked his friend.
“What is the price of the guitar?”, the friend asked.
“Play the other one for me.”
The gentleman got up, got the second guitar and began to play it.
“Well, what do you think?”
“This guitar is more open sounding than the previous guitar. What is the price?”
“The same. Should I buy it?”
“No. They are too cheap.” The guitar maker immediately got up and walked away.
The gentleman sat in the chair holding the guitar randomly picking notes while looking at the floor. He rose from the chair, put the guitar back in the stand, looked at me with a shoulder shrug and walked away.

Today’s Work


I am making this guitar for the 2021 Twisted Spruce Music Foundation Symposium and Competition. It has a salvaged old growth redwood top, East Indian rosewood back and sides and will be outfitted with an ebony fretboard on the mahogany neck. The sides are laminated with old growth redwood to match the top, laminated sides make for a stiffer rim than a regular side. The sides were laminated with epoxy and the help of a Roarockit Thin Air Press luthier bag and clamped to an internal mold. The sides ares attached to the top with blocks of Spanish cedar and hot hide glue from Tools For Woodworking

My Latest Guitar - European Spruce/Canadian Cypress, Available Late June 2021

My latest guitar has a European Spruce top, Canadian Cypress back and sides, Honduran Mahogany neck, Macassar Ebony fret board and bindings and an East Indian Rosewood bridge. Scale length is 654mm and the fret board a 20th fret. Body length is 490mm, body depth at heel is 100mm, body depth at end block is 106mm. Width at nut is 52mm, width at 12th fret is 62mm, string spacing at bridge is 59.5mm.

I completed the French polish last week and will start the final rub out on June 7, 2021, the guitar will be set up with strings the week of June 14, 2021.

I used buttonlac shellac to French polish this guitar, buttonlac is a tougher version of shellac and was once used to coat bowling alley lanes! If the shellac is tough enough to stand up to the abuse of a bowling ball, it should withstand use by a guitarist!

The bindings are Macassar ebony and are doubled up, meaning I used two strips of ebony to make a wider than usual binding for the guitar. This is a technique that was popularized by the luthier Art Overholtzer of Chico, California.

The sides are triple laminated, the exterior layer is cypress and the two inner layers are beech and maple, and this creates very stiff sides, a stiff rim gives the guitar more projection. The back is also triple laminated with the same woods, cypress exterior with inner beech and maple veneers, this also helps with the guitar's projection and greatly reduces the chance that the back will split due to neglect.

The neck head stock before the top was attached, the veneer is East Indian rosewood.

The guitar will be fitted with Schaller "Grand Tune" tuning machines which sport ebony buttons, black rollers with metal bearings for effortless and accurate tuning. 

If you are interested in purchasing this guitar, please contact me at

A Basic Tool Kit for Making a Classical Guitar - Another Look

I was looking at a blog post of mine from eight years ago, Basic Hand Tool Kit for Making a Classical Guitar, Revised and saw that I have made a few changes in my tool kit. Here are some of the changes and my current recommendations for someone who wants to make their first guitar.

I still recommend purchasing or borrowing one of the following books on guitar construction, but choose only one! Pick one book and make a guitar using that book and that book only! Using more that one book at a time will do nothing but confuse you! I speak from experience! Once you complete your first guitar then purchase other books.

Guitar Making: Tradition and Technology, by William Cumpiano and Jonathan Natelson


Making Master Guitars, by Roy Courtnall

You can skip buying a book and find a guitar making course here in the United States or aboard. There are many such courses available today that weren't available when I started this journey thirty years ago.

These books by Roy Underhill are still recommended reading:

The Woodwright's Shop

The Woodwright's Companion

The Woodwright's Workbench

The Woodwright's Apprentice

Why these books by Mr. Underhill? You will learn valuable wood working techniques if you make any of his projects. The dovetail joints used to join a drawer together are far more complicated than any joint you will use in making a guitar. 

A modern classical guitar is made up of butt joints and one scarf joint. Yes, there is the "V" joint to join headstock to neck shaft which requires much more patience and experience. You will do some inlay with the rosette and rout out a few rabbets for the purfling and binding, but there are no complicated joints, unless you join the neck to the body with a sliding dovetail or make a "V" joint to join headstock to neck shaft. 

I think it is easier to build a guitar than to build a Federal highboy.

The very first thing to do is  BUILD YOURSELF A DECENT WORK BENCH! Build something basic and sturdy with a flat top!

There is a plethora of information on the Internet about how to build a work bench, so much so it's a little mind boggling! It seems that many wood workers would rather make work benches than anything else.

I recommend making a work bench similar to the one in Underhill's, The Woodwright's Apprentice. It is simple, goes together quickly and I have been using that same bench for the last twenty years! If you want to, build yourself a Roubo bench, or a Nicholson English bench, which I think is the best bench ever designed; or make a Shaker style bench. Whatever bench you chose, just make it!

In my previous post on a basic tool kit,  I suggested looking for vintage tools at local tool swaps, flea markets and antique stores. I don't say that anymore, unless you are willing to spend the time and effort to restore these tools and if you don't want to do all that work, I suggest buying new tools, especially hand planes. 

The hand planes that are made and sold by Lie-Nielsen and Lee Valley are exceptional tools that are ready to use right out of the box. Yes, they are expensive, but they will save you hours of frustration of trying to restore and set up a vintage hand plane, and if you buy a Lie-Nielsen plane and you don't like it, you can sell it on eBay for as much as you originally paid for it!

If you do want to restore vintage tools, there are several books available on how to restore and keen vintage tools, not to mention the articles available on the Internet. 

Here is a basic list of tools that I use to build a classic guitar. And this is not a definitive list, just a place to start. By the best you can afford!

No. 62 low angle plane (highly recommended!)

No. 5 plane

No. 7 plane 

Low Angle block plane 

Lee Valley Spokeshaves, flat and round 

8 inch drawknife

1/16 inch 

1/8 inch chisel

1/4 inch chisel

1/2 inch chisel

3/4 inch chisel 

Marking gauge,  shop made or purchased

Cutting gauge, shop made or purchased

Sloyd knife, 3 1/4 inch blade (Mora of Sweden #106)

Card scrapers

Classic guitar tuner drill jig, with 13/32 inch drill. This is a must! Get the one from Stew-Mac. There are several other jig available.

Rosette and Sound hole cutter, available from from LMII or purchase an attachment for a Dremel router from StewMac

Dremel router, variable speed

Razor saws 

Fine tooth crosscut dovetail saw

12-14 inch crosscut back saw

20 inch rip panel saw

20 inch crosscut panel

Fret saw, buy the best and get the Luthier Saw from BadAxe Tool Works! I don't recommend any other fret saw, most aren't properly sharpened and you will have a hard time cutting slots in an ebony fret board!

Bow, or Turning Saw, available from Tools For Working Wood, or make your own. TFWW has parts to make one.

Dial Caliper, buy or make your own

Hand held electric drill, don't buy an impact drill!

Dead Blow Fret Hammer, from Stew-Mac

Diamond fret crowning file, from Stew-Mac

Side cutters for cutting frets, from Stew-Mac or LMI

Nut slotting files

Bending iron, buy an electric iron and spot thermometer from Stew-Mac

A Shop Fox vise, available from Grizzly, Stew-Mac and Garret Wade

Clamps-cam clamps (which you can make yourself), bridge clamp, C-clamps, long reach C-clamps, spring clamps, clamps, clamps, clamps. I use a vacuum pump and vacuum clamp to glue bridges onto guitar tops now.

I know I have missed some tools, but look at the tool lists in the book your purchase. 

Don't forget to join the Guild of American Luthiers. You can learn much from their publication, American Lutherie. You can learn so much from them that your head will swim and you will get confused!

And remember!

Try not, do or do not! There is no try.

Shaping a Classical Guitar Neck - My Latest Concert Grand Guitar


My wife and I took last week off for a quick get-away from the dreadful Denver 'burbs and now a new week begins back in the work shop. 

I carved this neck two weeks ago and today the goal was to finish shaping and sanding all the surfaces that a guitar player's thumb will be resting on. My guitar necks have a flattened "D" profile, in my opinion this profile is more comfortable, therefore more ergonomic that a standard "D" shape. The human thumb is not shaped to ride along a fully rounded surface, a flatter surface is more comfortable.

The heel is shaped in the manner that the Jose Ramirez III guitar shop used back in the 1950's and 1960's, no exaggerated dip and scoop, just a simple arc.

The profile gauge is to make sure that I get both sides of the heel shaped more or less the same.

The heel ready for "whiskering", raising the grain and final sanding before I start pore filling with shellac and pumice.

New Video - European Spruce/East Indian Rosewood Concert Grand Classical Guitar

My friend, Nathan Fischer, made a video of him playing a Concert Grand classical guitar that I made. Nathan is such a wonderful guy and boy, can he play the guitar! Along with teaching at Indiana University, he is a director of the Twisted Spruce Music Foundation. I am a sponsor of Twisted Spruce and I will donate a Concert Grand guitar to the foundation this year.

Moving Day - From a Small Shop to a Tiny Shop


I moved across the hall to a smaller studio at 40 West Art Studios today. The space I have occupied for the last year is 230 square feet in size, has an acoustic tile ceiling and is nearly impossible to humidify properly. The best the humidifier can do is 37% RH, when I run it at a higher setting the reservoir will run out of water overnight.

The space I moved into today is only 140 square feet in size with a lower ceiling that is dry walled,and I plan on installing a rubber door sweep to help keep a more consistent level of humidity.

For the last several months I have been thinking about how to reduce clutter, a good solution I found was to place things I hadn’t used in one year in a cardboard box and put the box in the FJ Cruiser. I need more boxes. 

I’m not sure there is enough room for a saw horse...

or all of my clamps!

The Dutch-style tool chest is going to be replaced with a sectional tool cabinet to organize my tools with a little more efficiency.

All this work to do organizing the shop and there are two guitars to work on. 

The Best Workshop in the World!

The best workshop in the world is the one that you are working in! I know that there are people who complain about their work space - it is ...
