This thread will be chronicling my Vintage Les Paul build.
After having built a number of Classical and Steel Strings over the past few years it is time to switch gears.
The build will be mostly faithful to the Gibson late-50's design.
I will be using a traditional Mahogany body and Curly Maple top, Maple-bound Rosewood fretboard with EVO Gold frets.
The neck will have the 17 degree headstock angle, and I will use a scarf joint (vs the traditional 1-piece)
The frets will feature hemi...semi...er....rounded ends (vs the traditional ABS binding notched at the fret ends)
For the maple top, I am planning a nice amber burst.
I was unable to find 13.5" wide 8/4 Mahogany for the body, so I found some nice 8" wide stock that I will be gluing up for the 2-piece.

This is gonna be fun, thanks for looking!

Rob

There are a number of excellent plans available for Vintage Les Paul builds.

It is generally accepted the John Catto plans are accurate for the body shape and various cutouts and hardware placements.
John Catto v10 Plans

The Bartlett Plans are also well regarded as accurate, with full neck details:
Clicky here for Bartlett Plans

The Stew-Mac plans are regarded as accurate for the neck, the body shape, not so much....

I will be using the Catto plans for the body and SM for reference.

Another good set of plans out there are the top carve profile plans:
Top Carve
Top Carve Cross Section

You will need a few copies of the Catto plans and the Top Carve profiles - I brought mine to my local printer and had 10 each printed out.
The plans are to scale - be sure to tell your printer to print them with the "No Scaling" option

All righty then - let's get started!

Here are the woods I have selected, after an initial run through the drum sander:

I will set them aside and get cracking on the templates....

A number of templates need to be built before getting started with shaping the body.
Here is the Catto plan - cut out four outlines 1/8 outside of the body profile:
Attachment:
IMG_2875 (Large).JPG

Attachment:
IMG_2876 (Large).JPG


Trace the plan out on a piece of 1/2" MDF, then cut the rough profile on the band saw.
Glue the plan to the MDF.

Great info. I just put together a Les Paul kit guitar for a friend. The quality wasn't too bad but really made me want to make one from scratch. I noticed in your posting above that you had some good references for the carved top of the Les Paul. Do you where I could find a solid model of the top that I could use on my CNC? (I am confident I could make my own model but just seems like someone has already done this!)

Thanks Brad!

I have not run across a model for the carved top - however there must be some out there!

Using the spindle sander to sand the edges almost to the line.
Attachment:
IMG_2878 (Large).JPG


Using a sanding block to sand the edges exactly to the line. The 1 1/2" rubber attachment from the spindle sander is perfect for shaping the upper bouts and the cutaway.
Attachment:
IMG_2879 (Large).JPG


Cut out and glue up two more plans and templates. On the Master Template, drill and countersink a screw hole in the center of each pickup, and screw the master template to the second template, ensuring the centerlines are exactly lined up. Use a pattern bit and rout the second template so it is a perfect copy of the master. Repeat for template #3.
Attachment:
IMG_2880 (Large).JPG


The 3 templates are ready to configure.

Some progress on the templates. Much effort must be made to ensure the templates are exact.

To shape the cavities, first hog out as much material as possible with a 1" Forstner bit, just inside the line:
Attachment:
IMG_2882 (Large).JPG


Here is one pattern all hogged out:
Attachment:
IMG_2883 (Large).JPG


Shaping the cavities on the spindle sander (followed by shaping and smoothing with files):

The back has been thicknessed to 1 3/4", and the master template was used with the 3/4" top bearing pattern bit to shape the sides. Mark the switch and control cavities with a pencil.
Attachment:
IMG_2893 (Large).JPG

Hog out the cavities with a 1" Forstner bit to 1-1/2" deep.
Attachment:

Hogged out and ready to route.
Attachment:
IMG_2895 (Large).JPG

Use the top-bearing pattern bit to create the cavities.
Attachment:
IMG_2896 (Large).JPG

Remove the template to get enough depth for the last pass. Route to 1 11/16" deep, leaving 1/16" of material.

Control and Switch Cavities done
Attachment:
IMG_2898 (Large).JPG

Routing the Cable Channel with the pattern adapter and a 1/4" bit. The cable channel is 1/2" wide and 1/2" deep.
Attachment:
IMG_2899 (Large).JPG

Note the channel just cuts into the control cavity, and well into the switch cavity, to allow room for the switch.
Attachment:
IMG_2900 (Large).JPG

Align the top to the back and drill 1/8" holes through the top into the back by 1/4". Use the screw holes used previously by the Master Template, which are in the center of the pickup location. Insert 1/8" dowels 1" long to align the top during glue-up.
Attachment:
IMG_2901 (Large).JPG

Keep the glue at least 1/2" away from the cable channel.
Attachment:
IMG_2902 (Large).JPG

The top was thicknessed to 5/8" and rough shaped with the bandsaw, ensuring the centerlines line up. Using two templates as clamping cauls. Clean up the glue squeeze-out ASAP.

Thanks to ExNihlo for making these top profile maps available. They are a topographical map of a '59 burst, in 1/16" gradients. Cut out the 7 profiles and glue to 1/2" MDF. The 8th print is left whole and glued to the maple top.
Attachment:
IMG_2904 (Large).JPG

They are cut out with the bandsaw, then smoothed to the line with the spindle sander.
Attachment:
IMG_2905 (Large).JPG

Using a bottom-bearing flush-cut bit to trim the top to the sides. Then sand the sides perfectly smooth up to 220.
Attachment:
IMG_2906 (Large).JPG

Before contouring the top, use the Master Template and drill 1/16" holes to mark the center location of the pots and the switch - they are a pain to mark later....
Attachment:
IMG_2907 (Large).JPG

The full pattern has been glued to the maple top. Here the first gradient pattern is screwed in place. Using a pattern sleeve rout down in 1/8" increments until there is 3/16" left above the back. In this case, The top is 5/8", the pattern is 1/2", so the final depth of the first rout is 15/16". Successive patterns will be routed 1/16" less.
Attachment:
IMG_2908 (Large).JPG

After stepping down 1/8" per pass, the first 15/16" cut is complete
Attachment:
IMG_2909 (Large).JPG

All the passes are complete, creating the rough profile of the top

To route the neck angle, mount the body with the centerline square to the hinged routing jig
Attachment:
IMG_2917 (Large).JPG

The target neck angle is 4.4 degrees as shown.
Attachment:
IMG_2918 (Large).JPG

Use the jig as shown to route the neck angle. Increase the depth by 1/16" per pass to keep it smooth. Continue routing until the depth of the maple top at the neck/body join matches the rest of the body - 3/16"
Attachment:
IMG_2919 (Large).JPG

Perfect!

The target pickup angle is 1.2 degrees.
Attachment:
IMG_2921 (Large).JPG

Route the pickup angle, increasing the depth minimally per pass. the target depth is reached when the intersection of the neck angle and pickup angle is exactly at the end of the fretboard (and start of the pickup ring). In this case, the line was 82mm in from the top edge of the body.

Using the Troji guitar vise to hold the body.
Attachment:
IMG_2944 (Large).JPG

A 3/16" roundover bit is used on the back edge. This step is done near the end of the body build to protect the edge.
Attachment:
IMG_2945 (Large).JPG

The 1" output jack hole is centered in between the edge of the roundover and the binding. The location in on the Catto plan. A 1" forstner bit is used. Stop drilling once the bit just reaches the control cavity to prevent tearout in the control cavity. Complete the hole in the cavity with a round file.
Attachment:
IMG_2946 (Large).JPG

Locate the tailpiece with the Catto plan, ensuring it follows the centerline. Check that your tailpiece matches the plan. The Gotoh unit is standard 3-1/4" on center, which matches the plan.
Attachment:
IMG_2947 (Large).JPG

The 7/16" tailpiece bushing holes were drilled exactly 1" deep. Before installing the bushings, a 1/8" hole is drilled from the treble side bushing into the control cavity for the ground wire.
Attachment:
IMG_2948 (Large).JPG

After feeding the 22ga tinned ground wire through the hole, leave 1/2" in the bushing hole, then install the bushings. The top of the bushing should be just below the surface. Use a small socket and extension to seat the bushing.
