Featured Restoration ( A Broken 12-string)

A brother in Christ has brought to me his dear Takamine 12-string after a tragic incident that occurred in his house. Fortunately only his 12-string was affected and nobody was harmed, Praise God. He told me to be wary of IKEA shelves, don't load it with too much weight ... his Takamine 12-string has suffered impact blows from a string of falling objects when his IKEA shelves gave way to the constant loading from the items they were supporting. The impact has resulted in a broken headstock. It was indeed a guitar lovers' nightmare, equally to a guitar restorer ... This is one of those challenging restoration jobs that are talked about ...

This brother is a close friend. I took up this challenge as a way to reciprocate my gratitude towards him for being a brother in Christ and a faithful friend to me.

Lets' take a look at the start state. The headstock was totally severed from the rest of guitar.

Fortunately or usually, such cracks are repairable. You can also see the severed fibres are perfectly matching to each other.

Headstock Back
After studying the mechanics of the crack and the wood grains of the neck, time to get started.

Some wood splints and chips were carefully removed from the crack areas to avoid possibility of weak sealing between the crack areas when glued. The easy part was to glue the two parts together.

Glued and clamped
The wood glue needed only 30 minutes to set but it was recommended to not stress the glue joins within 24 hours.

Curing for the next 24 hours
After the glue has cured for 24 hours, the clamps and wooden blocks were removed. Usually the excess glue will ooze everywhere and cleaning was inevitable.

Glued Headstock Front
Glue marks were easily visible.

Glued Headstock Back
This is a 12-string, and my brother told that he has no intention to load all 12 strings on it from this point on. So he said I didn't have do a lot, just glue it back will do. However, it woud be hard to believe that the glue will be able to hold the tension exerted by all six strings. More has to be done ...

I think that both front and back of the headstock need to be reinforced. So I begun from the back.

Cutting a seat for the mahogany stripe
I used a piece of hardwood (mahogany) to reinforce the weakest part of the guitar neck.

Gluing again ...

Same rules apply ... 30 minute/24 hour
After glue is cured.

I went on to work on the headstock front

A square seating was cut into the headstock front
The tricky part ... the square seating was cut according to the size of the reinforcement wood. In this case, I should have used tonewoods but I didn't have any of the shape and size readily. Nevertheless, a piece of hardwood was used for reinforcement.

Gluing again ...

Same thing ... 30 minutes/24 hours
When the glue was cured.

I didn't think that my friend was going allow the two reinforcement woods to stick out like sore thumbs, so the excess wood must be removed.

Most sanding and shaping work were done finally. Next, I went on the stain the reinforcement woods to blend into the guitar neck.

For the headstock front, the reinforcement wood needs to be varnished.

Clear Satin varnish was applied to the demarcated area
Buffing ... the back

the front ...

Pretty blended
This dear friend of mine usually forgets a thing or two ... there was no guitar nut when he handed the guitar to me. So I was left with the options to buy a standard 12-string plastic nut, or hand-craft one. For this friend, I have decided to hand-craft a 12-string guitar bone nut ... oh dear ...

However, he has emphasized that this guitar was not going to hold 12 guitar strings anymore but I have cut light marks for the high octaves strings set in case he changes his mind later on. You might be able to see in the pictures below.

Finally, the completed work! My dear friend's 12-string has been restored and road ready again! It was tough but it was rewarding to see it through.

It is finished!
Praise the Lord for seeing me through this entire process.

Featured Restoration (A Taylor Baby Story)

Dear All,

Every now and then, I will get some uncommon restoration job requests. These guitars bear certain unique identities that were like no other. It was not about price nor the superiority in the wood but the strong bond between the guitars and their owners. Some jobs were down-right economically not viable to be undertaken but these owners have insisted that prices were not the main concern although it is worth weighing. The overwhelming desire to have the guitar restored back to "the desired state" was the main challenge for me. It is ethical to remind the owners the impending investment and the expected outcomes. If owners are agreeable, the jobs get a green light to proceed.

While there are many websites in the internet that feature the quality of the restoration jobs, this feature article is all but for this purpose. I thought it is valuable to share with this unexplainable passion to anyone who cares to read this article, and passing the flame to more people who are playing guitars, stopped playing guitars, play guitars once in a blue moon, just picked up guitars and those yearning to do so.

Here goes,

It is a Baby Taylor, arrived with a cracked neck. After ten plus years on the road, inevitably the road wears were noticeable at various areas the Baby. The owner requested for re-glue of the neck, replaced new bone nut/saddle, set-up, clean up. There is an"off limits"area that ruled out any restoration jobs regardless if they are desirable or not. I'll let you savor the moments of this process until the last few pictures where you will be able to see the "off limits" area. You will understand immediately the reason.

Notice the glue marks, the crack line was glue marks (picture below) ... Baby Taylor's headstock is glued to the neck by means of Taylor's unique finger joint. The crack propagated from the joint ...

Glue is applied to the crack line

More pictures of the clamping process ...

Curing
My concern was the puny bit of glue to take on the string tension ... as it turned out, the glue dislodged and the crack re-appeared when I loaded the string tension upon the guitar. As such plan B was incepted. While it was not my favorite but it was a viable option, i.e. to reinforce the cracked area with another piece hardwood. A cavity is routed out from the crack area and a piece of mahogany was introduced into the cavity. (see picture below)

The reinforcer was glued in place
The piece of mahogany was glued in place. Again, another 24hrs of curing. Thank God for Titebond wood glue, things were made much easier.

Clamped for glue to cure
Once the glue is cured, time to sand the mahogany to flush with the neck.

Dremel ... carefully removing excess wood
Wah lah! Almost flushed!

Much excess is removed
The final sanding was done by hand. Scratches were inflicted onto the surrounding areas during the sanding process thus these scratches have to be removed by buffing.

Buffed ... most scratch marks were gone
An important thing I have learned was that all structural issues on the guitar must be addressed prior to other jobs like aesthetic upgrades or pickup installations. Finally the neck was reinforced, and with peace of mind I moved on to install the new bone nut and saddle. Once the new bone nut and saddle were installed, setting up and tune up follow. It was a great relieve that the mahogany was able to hold the neck together. Here're some pictures of the restored guitar.

You may wonder now, what was the unique identity of this Baby Taylor? A friend to this owner has drawn an illustration of a toddler, munching away some food, who is the son of the guitar owner. That fully qualifies the "off limits" status. Does it not remind us that youth is invaluable and to cherish the food delivered to our tables daily? The illustration was completed with pencil ... on the top plate.

Enjoy the last few pictures to sum up the story!

Such detail touches
Nothing could drive me to clean the illustration away, it is sin to do that. From another angle ...

Finally, the Baby Taylor.

Yes! It is done!
If you got till this point, I really appreciate the time you spent. Stay bless!
