Venezuelan Cuatro Rebuild by Kevin Parsons – Part 2

The back is repaired

I missed seeing how Kevin removed the back off the cuatro.  There were questions about how he did this when I posted these photos and videos on the Facebook Group “UAS Anonymous” last year.  There is a video later in this series in which Kevin explains how he did this, the tools that he uses and what to watch out for if you are doing this at home!

The crack in the back being repaired

The crack has been glued. Then the back has been clamped with wedges while the glue sets. (There will be videos all about glue later! Be patient!)

Video 01: Unclamping the repaired back

Video 01 Transcript

KEVIN: The crack runs between those bits of tape. And these two bits of wood are locking down.

And that wedge is shoving that half into there and these two are just to keep it flat.

LIZ: How long will it take?

KEVIN: It’s done, I’ll do it now.

I’ll pull that wedge out, undo these, and there’s the crack in between . . .

And what I’ve got to do now is, I’ve got to reinforce that with some little diamonds (made of wood!)

It’s got to be reinforced . . . and then I’ll put bars across.

You can photograph what I am doing with it next time.

LIZ: Okie doke! You’ll have the little diamonds stuck on it then?

KEVIN: Yeah.

The repair is reinforced by “diamonds”

Video 02 Transcript

KEVIN: The cuatro is made very simply

I’m going to make it a little more complicated than it was.

It will be stronger, better sounding instrument.

I’ve taken off the back edge, what we call “linings” . . .

which are these small support blocks

which give a glueing surface

between the back and the sides

and the top and the sides.

Originally it was these small blocks

I’m going to replace it with this, what they call “kerf lining”

which is more solid . . . joint

I’m going to bend this to the shape of the sides

and fit it around. When I’ve done that it will be strong enough

for me to take off the small blocks

and replace them

with a much more dense set of linings.

When I’ve done that, I will also take off these two braces

and put on a slightly more nicely shaped set

that will also have side supports coming up

to stop them from ever moving.

And then we will be ready for the back to go back on.

So that’s the lining that’s glued onto the back edge

(Unintelligible)

LIZ: After what?

KEVIN: As is being revealed!

[Turns off noisy humidifier!]

KEVIN: So that’s the linings on the back edge.

And that’s the back, with the big crack

glued up and reinforced

Two small braces glued on, which I’ll shape down

and scallop the ends off.

And these two braces will go into notches I cut in the linings.

And that goes back on.

And that will have made the back a lot stiffer than it was before

So that should improve the brilliance and the sustain.

So what happens next is . . .

LIZ: You stolen those clothes pegs off my line?

KEVIN: You can’t buy these clothes pegs any more.

You can just buy horrible, plastic ones.

They’re too weak.

No good for a guitar maker.

So what happens now is . . .

I will do work on the top.

I will take these little blocks off

and fit a more constant stream of blocks

to the top and the sides.

And when I’ve done that

I can get rid of these two braces

And I’ll fit these ones in. They’re not finished yet.

But they will fit into there . . .

and there.

And they will have little side braces

coming down onto the ends

to hold them in place and to strengthen the sides.

These back braces, similarly, when they go on

will have a brace coming up the sides

to meet onto the end of it.

When that’s done, these will become

three little fan braces,

which will cut short of that brace,

and sit there on the inside.

And that’ll be just about the insides finished.

And then we can go on to the other side after that
