Ibanez Jem Refret

After tackling the maple board, it's time to refret an ebony board which can sometimes be prone to chipping. Here's how it went:

Photobucket
Before entering the operating theatre.

Photobucket
Steve Vai's signature which offers no particular significance nonetheless.

Photobucket
Worn out frets. Not particularly bad, but the owner wanted a change in fret size and some notes were choking on the upper frets

Photobucket
Frets are removed and the fingerboard is checked with a radius gauge. 16" radius it is.

Photobucket
Inevitably, some chipping occurred as the frets were removed.

Photobucket
Chip is reglued.

Photobucket
Another chip.

Photobucket
Ebony dust is also used to touch up the chipped areas.

Photobucket
Using a 16" radius block, the fingerboard is sanded down.

Photobucket
Photobucket
Photobucket
After leveling the fingerboard, the chipped areas look acceptable. After putting on the frets, the repair should be near invisible.

Photobucket
Photobucket
The frets are seated in with a hammer and ready to be pressed in.

Photobucket
Frets are pressed in with a radius caul on the drill press. I don't always use the radius caul to press in the frets and actually I prefer the hammer most of the time.

Photobucket
The frets are pressed in to perfection - absolutely no gaps showing :)

Photobucket
Frets are leveled and due to the meticulous fretboard prep, only a light level is needed.

Photobucket
Routinely, the frets are checked with a straight edge. No problems here.

Photobucket
Photobucket
Photobucket
The frets are trimmed, crowned and polished. As you can see from the various angles, the fret ends are rounded off for playing comfort.

Photobucket
Guitar is strung up and ready to rock!

Hope you enjoyed that,

Refretting a maple Strat neck

I have here a 57 RI Fender Strat which needs a refret. Maple necks are hard to handle and some lacquer chipping usually occurs no matter how careful one is. Certainly, the best way is to relacquer the neck, but sometimes cost is a consideration and here, I'll have to work with the original lacquer. Here goes:

Photobucket
Handsome looking burst

Photobucket
Original frets have worn out

Photobucket
The lacquer overhanging the fret is adroitly removed with an Xacto knife.

Photobucket
Frets are heated up and removed with a cutter ground flat at the jaws.

Photobucket
Some lacquer buildup is still present and a micro chisel is used to fix that.

Photobucket
Frets removed and not much major chipping

Photobucket
I then stained the maple to give the neck an even look throughout. This allows an acceptable appearance when touching up the chips with lacquer later.

Photobucket
The frets are hammered/pressed in and a fret level is being done.

Photobucket
As the frets were hammered in nice and tight, only a very light level was needed as you can see from the metal filings.

Photobucket
Quick check across the frets revealed no problems.

Photobucket
The fingerboard is taped up once more and the frets are crowned, trimmed and polished.

Photobucket
Finally, the end result. The neck feels new and plays well again.

What goes in your Setup (Acoustic)

Continuing the 'What goes in your setup' series, we have here a Larivee L-03 acoustic guitar. I would consider it a mid to higher end production guitar and as you will see, many of the problems associated with guitars has nothing to do with the price. A higher priced instrument can eventually develop fret problems.

Here's the process in its entirety:

Photobucket

I'm impressed by my Powershot's as well as my own limited abilities :)

Photobucket

Guitar sitting on my workbench feeling helpless.

Photobucket

Many frets have popped up at the ends and this is the first thing to fix

Photobucket

Fret reglued. This is a time consuming process and in total I glued in more about 20 loose ends which took about 30 mins.

Photobucket

A notched straightedge is used to set the neck perfectly level (truss rod needing adjustment of course!)

Photobucket

Frets are polished with steel wool.

Photobucket

Nice and clean.

The nut action didn't need any tweaking so I proceeded to measure the action with a long ruler. At the 12 fret it measured about 2.2mm on both the bass and treble. I had to take down the treble side more. Point to note: to reduce action on the 12 fret fret by 1mm, approximately 2 mm had to be taken down on the saddle. Good ole trigonometry at work here, finally a use for it so many years after leaving school!

Saddle is brought to the appropriate height. Final sanding on a flat surface is crucial to good contact with the bridge, hence producing better tone.

Photobucket

Upon stringing up, I realised there was a 'sitar' like sound on the high E. A quick check revealed a poor break angle to to the bridge pin. Notice how shallow the angle is compared to the rest of the strings.

Photobucket

Photobucket

Without haste, I put my chisel to work and notched a deeper string slot groove at the bridge pin hole. Now, the break angle is much more desirable and the 'sitar' like sound is gone.

Photobucket

After stringing up and a wipe down, I couldn't put this baby down. A great setup could make all the difference, regardless of the price of your guitar.
