This project has the goal of replacing the standard bridge and saddle with a Portland Guitar Split Saddle Bridge.

( 01 ) 17-Sept-18

Here we are removing the strings from this brand new Seagull guitar.

( 02 ) 17-Sept-18

I took the bridge apart to see what we see. This is a standard straight line saddle with a piezoelectric pickup under the saddle.

( 03 ) 17-Sept-18

This is what we want the current saddle to look like.

( 04 ) 17-Sept-18

Here I am using the CNC Router to create the individual saddle plates.

( 05 ) 17-Sept-18

And then making the individual saddles.

( 06 ) 17-Sept-18

We put them together.

( 07 ) 17-Sept-18

Next I turned my attention to making the template that I will use to guide the router as it cuts the channel in the existing bridge.

( 08 ) 17-Sept-18

 

( 09 ) 17-Sept-18

Having learned from experience I make a test cut to make sure everything fits just right.

( 10 ) 17-Sept-18

The test channel with the individual saddles.

( 11 ) 17-Sept-18

A good fit.

( 12 ) 17-Sept-18

I will use the template in this general purpose fixture that suspends the template over the existing bridge. Once I am confident I have it in the right place...

( 13 ) 19-Sept-18

This is the hardware that centers the fixture.

( 14 ) 19-Sept-18

The insert.

( 15 ) 19-Sept-18

 

( 16 ) 19-Sept-18

Three stiff cushions to support the fixture without damaging the finish.

( 17 ) 19-Sept-18

Fixture in place.

( 18 ) 19-Sept-18

 

( 19 ) 19-Sept-18

Exercise bands to secure the fixture.

( 20 ) 19-Sept-18

.

( 21 ) 19-Sept-18

And a C-clamp for good measure.

( 22 ) 19-Sept-18

I drill out the pin holes to a standard size...

( 23 ) 19-Sept-18

and fit ebony plugs in the old holes.

( 24 ) 19-Sept-18

They get glued in and the gaps filled with ebony dust.

( 25 ) 19-Sept-18

Sanded flush.

( 26 ) 19-Sept-18

Now everything get put together.

( 27 ) 19-Sept-18

I take a deep breath...

( 28 ) 19-Sept-18

and cut the new channel.

( 29 ) 19-Sept-18

 

( 30 ) 19-Sept-18

 

( 31 ) 19-Sept-18

 

( 32 ) 19-Sept-18

Success!

( 33 ) 21-Sept-2018

The drill again... for the bridge pins.

( 34 ) 21-Sept-2018

After a bit of concentrated setup the guitar is finished.
