The Glues That I Use

While the most visible features of a fine quality guitar are the materials and craftsmanship used in conjunction, another factor that contributes to quality are the adhesives used to hold it all together.

Jose Oribe, The Fine Guitar, 1985

I want everyone to know that I am not receiving any money from any of the glue manufacturers that I will talk about in this post. These are the glues I use when I make a classical guitar or on other shop projects.




Here are my go-to glues.



Titebond and Titebond II are PVA glues that I use for glueing the scarf joint on a guitar neck and the heel block to the neck shaft. Titebond sets quickly, has gap filling properties and when I do my part on making a good joint, the glue line is almost invisible. Fish and hide glues tend to absorb the water present in shellac and can become dark making the glue line more pronounced.

I also use Titebond to glue the joints for the tops and backs for the same reason. I don't want the glue line to stand out.



LMI yellow glue is pretty amazing in how quickly it sets, you can mill parts glued with this within 90 minutes after clamping. It dries very hard, almost as hard as hide glue, a big consideration for string instrument makers. It is believed that hard glue joints make the transmission of energy easier and quicker, this helps that instrument sound better.

The only drawback about the LMI glue is if the glue is too cold, it becomes chalky. I have found that if I use this glue when it is below 80 degrees Fahrenheit and 50% humidity, it will leave a white residue in wood pores. That makes for more work especially when using this glue on walnut or East Indian rosewood, I spend more time washing out the glue than working on the guitar.

That said, it is great glue.



I can't say enough good things about fish glue. I usually purchase fish glue from Lee Valley which is a high quality glue that I like very much, however, the smallest bottle is 16oz. in size and it takes me almost two years to use an entire bottle. I bought this small bottle from LMI and wow! this stuff will glue your fingers together!

I use this high tack glue to glue on binding strips and sometimes, if I am not in a hurry, I use it to glue the braces onto guitar backs.



This is the stuff!

Granular hide glue is simply amazing! It has a much and sometimes more shear strength that "modern" glues and dries glass hard, again, that is better fro energy transference.

I use hide glue where it really matters in guitar making - glueing the braces onto the top and back, the linings to the sides and glueing the back onto the guitar.

Every wood worker should try hide glue at least once on a project. Just make sure you have a heat gun handy to warm up all the parts that will be glue together.

Adhesives are what you make of them, each has their advantages and disadvantages, you need to experiment to find what works best for you and your projects.

Now, turn off your computer and get out into the shop!

  1. I use hide glue and the LMI yellow glue. Great stuff! In Winter when I worry about LMI glue possibly freezing during shipping I use that much more hide glue and/or Titebond. I haven't tried fish glue yet but I think you've convinced me to give it a try!

  2. Hi, Doug! Definitely give fish glue a try! Go to https://journeymansjournel.wordpress.com, he posted about fish glue and how he came to terms with it! Good luck!

How to Make a Traditional Froe Mallet

What holds the Holy of the Holies, what did Brahma become? Wood. Why will aspen always tremble? For the nails driven into the cross. What makes the color of wood? The soil it tastes. Cradle, fiddle, coffin, bed: wood is a column of earth made ambitious by light, and made of beauty by the rain.

Kim R. Stafford, Having Everything Right, 1986.

Rive, verb, to split
Shake, noun, a split in a piece wood. (Heart shake, ring shake)
Shake, verb, (Middle English), to split.

I know I should have been in the studio working on my back log of guitars, but the day was so nice and warm with a tall blue canopy, I couldn't stay inside. I decided that I needed to make a proper froe mallet. This style of mallet is traditional to northeastern California, primarily Tehama (where I'm from), Butte, Shasta and Plumas counties where making shingles by hand from sugar pines was an industry. I don't know if it was used in any other region along the Pacific Rim, other parts of the United States or even o…

Basic Hand Tool Kit for Making a Classical Guitar, Revised

Ours is really a simple craft.

James Krenov, The Impractical Cabinetmaker, 1979


So, you want to build a guitar.

Since the original post, Basic Hand Tool Kit for Guitar Making, click here to see it, is the most popular post on this blog, I thought I would revisit it and adjust it to what I am using now to make a classical guitar.

The first thing I recommend doing is to buy or borrow copies of the following books:

Guitar Making: Tradition and Technology, by William Cumpiano and Jonathan Natelson
Making Master Guitars, by Roy Courtnall
The Guitar Maker's Workshop, by Rik Middleton

These are required reading before you begin making a guitar.

Also required reading are these books by Roy Underhill:

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 mor…

The New Workshop: New Roof, Snow, Rain, Sub-zero Temperatures

A snowflake is one of God's most fragile creations, but look what they can do when they stick together!

Author Unknown


Cold weather and snow delayed me in getting down the corrugate tin roofing on the new workshop. January 3rd proved to be a day of snow flurries and sunshine which at least allowed me to install the roofing. Then it snowed six inches.


The temperature fell to -5 degrees Fahrenheit and it kept snowing...


...until there was 22 inches of snow on the ground. And the temperature fell some more to register -14 degrees Fahrenheit on the thermometer.



Yesterday, the temps warmed up to 36 degrees Fahrenheit with the wind gusting up to 50 mph and we lost power for about two hours.

This morning we woke up to rain and warmer weather. I am very glad that I got the new workshop "dried in" before all this snow fell.



The high reached 40 degrees today with rain and snow flurries, there is a good six inches of slush underneath all the snow. No wind to speak of today, though…
