Making the binding and purfling of guitar (front)

20201219
Now to work on the front binding channel side.
I had to figure out how to hold the guitar this way.
So I added a wood tension and clamp down the guitar.
I also fixed the L wooden bracket with dowels.
Now I am ready for the front binding channel.
For this side I go by the hand binding route instead.
I find that it has more control.
Luckily for me I had my own binding cutter as well the LMI gramil.
I set mine as the top cutter and the gramil as the side cutter.
This time round I use my 2m chisel and shave down the sides as I scribed it.
This method works great but abeit slower.
My paring chisel with a square reference (not bevelled) works great in this case too.

Merry Xmas everyone.
Next I began to cut the purfling channels.
This is relatively easy as the cutter can easily scribe the spruce without any issue.
I only need to control the depth not to cut too deeply.
But even if cut all the way thru' it should not be an issue, as my linings are about 10mm wide more than enough to support the top.
To cut the purfling channels accurately, I use my router plane and set the depth and cut in 2 passes.

When the channel is ready, I began to glue the purfling after some test fitting.
For holding the purfling, tape is still the best medium as it can apply the force in a wide area (equals the width of the tape used) After some time the gluing is done.
I did a joint on the purfling, which looks very good.

A Happy New Year to all!
I began gluing the front binding after checking all the fit.
I was contemplating whether to do both at the same time or one by one.
If doing one by one, the fitting at the butt end can be made to perfection.
But the rope pressure might damage the purfling.
If doing both at the same time, the fitting could be more tricky to handle.
In addition the rope tying sequence will be affected unless I started at the waist.
In the end I decide to go one by one.
Again by using just rope only I am able to see any gaps and close them before the glue dries.
If surrounded by tapes, I cant see anything...

The next day I did the other side repeating the same procedure.
The purfling was alright luckily.
Anyway the purlfing is a bit proud of the top surface so it can be sanded down easily.

Once the glue dried completely, I took off the ropes and began to scrape the binding flush with with sides and top.
There are some areas which I fill the gaps with saw dust and glue.
The effect came out very good.

First of all I decide on the binding to be used.
Originally it was planned to be using red colour binding (blood wood) but because the body itself is a bit reddish brown, the contrast does not come out good.
So after discussing with the owner, we decided to use ebony instead as it provided a good contrast with the backs as well as the top.

Bloodwood binding (not so good contrast)

Maple binding (good contrast with back but not so good with top)

Ebony binding (good contrast with back and top)

After all is done, I finally began to cut the binding.
The binding jig works relatively well, but I did some tweak to the binding jig to make it track better.
The top part was extend a bit to make it more stable while the side reference is made closer to the binding bit.
After both channels are cut, I use my chisel and files to correct the binding channel itself.

After that I spend some time to correct the channel dimensions using chisels, files, and rabbet planes.
Then I cut the end graft channel using saw and chisels.

Next I began the binding process.
At first I wanted to use the binding jig for working 1/2 the sides of the guitar, but in the end I just go without it as it's easier to access all parts of the guitar while working.
First I glue the purfling using white glue and CA.
The CA will hold it in place while the white glue gives it strength.
Next I began glueing the binding.
After measure and cutting, I began at the end graft area.
As I tied the ropes, I began to glue the binding also.
Similarly I use CA at certain points to help to hold it.
At some portion I had to use big clamps to force it in place due to the spring back of the binding.
Finally as I reached the heel area, I cut the excess and glue in.

Glued the purfling using white and CA glue.

After scraping the binding, the binding looks good without major gaps.
The gaps can be closed easily with some CA and clamps.
Next will be the other side of the binding.
To make them fit I tie the 2nd binding flush with the channel and mark the length at the butt end.
Then I trim it using a saw.
When I started binding I started with the butt end instead of the waist.
When I reached the heel end then I measure and saw to length and adjusted with chisel.
This way the fiting is perfect without any gaps due to overlength or underlength.

Next I plane and scrape down the 2nd side too.
Good no major gaps.
