These are pictures of the ForumIII guitars in progress sent to me by John Larrivee Jr. They are also posted by him  in a Facebook group called "Larrivee Forum III guitar".

The links will be to the full size images, about 1.7mb each of the same pictures.

6
Antonio is adjusting the index bolts to ccommodate the 4" lower bout depth specification.
7
The sides are bent, head an tail blocks have been assembled.
8
Mario is preparing the frame for kerfing. Kerfing is a liner that goes inside the frame to create surface area for the top and back to be glued on. We'll see more of this later.
9
These LS tops are the first to get into the climate room. Here they will sit for at least 72 hours and slowly adjust to a humidity of 44%.

10
Andrew, who does a lot of the top processing, is jointing the Italian spruce before gluing.
11
This is Kirk. Kirk does a lot of the wood processing downstairs at Larrivée. Here he is roto plaining the LS tops after they have been glued. Then onto the laser.
12
The laser goes twice around to insure a clean cut.
13
Some more before and after laser. I thought it would be interesting to see your serial numbers going through. Later you can match them up with your Forum Guitar #

This top has just been glued.

This is Bob, Mario's son. He is about to glue the braces on the LS tops using a vacuum press.

Keeping track of things.

18
With a little glue and a few taps the taile piece is snug. Side grinding is next for this frame.
19
Ebony headstock veneer being lined up and glued onto the 12 fret neck.
20
A pneumatic press is used to clamp down on the veneer giving it firm, even pressure. These are all the 12 fret necks for your LS's. It wasn't too long ago this was done using hand clamps.
21
Turnbuckles help keep the frame true to it's shape.

22
Snug fit. This is the first of body assembly. Here at Larrivée we refer to this department as the climate room. It maintains a strict humidity level of 44%.

The black patch on the waste is a reinforcement for a pickup installation.
23
A little bit of pencil makes the serial numbers more visible.
24
Here Gonzalo prepares the inside of the top by scraping and sanding each brace.

26
This is Neil. Neil has been with Larrivée for over 20 years.
27
This is Conner Iannone. Does the name sound familiar? It should. He is one of two son's of David Iannone, the man behind Morgan Guitars. Conner has the hands and skill of his father. The sky is the limit for Conner should he choose a career in guitar building.
28
Every Larrivée top and back is hand fit to the sides. The bracing and notches will all fit snug.
29
This LS has just had it's top just glued on. The back is next.

31   
Chris has been Larrivée's side bender for many years. He is also responsible for matching backs and sides. He has a great eye for it.
32   
Chris has just removed this LS from the bending mould. Next it will cool down and any excess moisture from steam will evaporate. Now it will head up Antonio and the kerfing dep't.
33   
Waiting to go upstairs
34   
Looks like some cutaway's are going through now.

35   
Andrew jointing up some South American Mahogany.
36   
The first batch of 12 fret necks are moving along.
37   
Jigs are used in all sorts of process'. This one is to keep the necks measurments consistent.
38   
Soon this batch will be of to the CNC for contouring.

Neil is trimming the excess of the headstock.
40   
Here's Kirk again gluing some South American Mahogany backs. He's also been around 10+ years.
41   
Another back is going into the pony-clamps.
42   
Andrew is jointing more S.A. mahogany for Kirk to glue.

43   
Here the two LS sides are being joined by the head and tail blocks. The body now starts to take on its familiar shape.
44   
Bessey clamps are used for clamping the blocks to the sides.
*The two digit numbers you see on the sides are not the Forum III Guitar numbers. They are used as a reference much earlier on in the matching stage done by Chris.
45   
A full rack of LS rosewood waitng for blocks to dry. After this, Mario will begin kerfing this rack.
46   
This is the pickup reinforcement patch applied. Customers often inquire what this patch is for. For those who do not purchase a guitar with a pickup, it alows you the option for a future installation.

47   
Moulds are used to glue the patch. This creates complete and even surface pressure for drying.
48   
Serial numbers are still hand stamped here in Vancouver. The number is read off the side of the frame and reproduced on the headblock.
49   
Azucena prepares the numbers and checks for their correct sequential order.
50   
A quick tap is all it takes for the impression to be made. Later, a pencil is used to darken the impressions.

I don't think ben is around here.

So I will post some photos from facebook

pic 1. These frames a just of the drying rack. The head and tail blocks have been drying for about 4 hours. Next they will be frame sanded and kerfed.

pic 2. If you log on to www.youtube.com and search "Amstel Light Beer Commercial - Live Tastefully" you will find an surprising commercial. It starts with our very own Mario working on a guitar and features Larrivée props. The 31 second commercial was only released in Europe.

http://www.youtube.com/watch?v=TVFcDLreoaE

pic 3. Mario is kerfing some of the first rosewood LS's to go through. He uses a few different mini clamps for gluing. The smallest one can be found in most offices clipping paper.

picture 4.
The 3 dot 12th fret position markers commemorate the Forum III Guitar. Next for these fingerboards its on to get ivoroid binding.

Description

1. 12 fret fingerboards are being contoured on the CNC. They have also been shortend to accommodate the 12 fret to neck joint.

2. This machine, somtimes refered to as "the wheel of fortune", is actualy a frame sander. There are two of them. One is flat(for top) and the other is arched(for back). This process alows for tight and consistant control of the body depth. For the Forum III guitar, the pins were adjusted for a 4' lower bout depth.

*Notice turnbuckles securing the frame to the mould.

3. Moulds are used several times during the building process. This allows for better management of the frame.

1. A pair of tops and backs comming out of the vacuum press. After they are removed, Bob wil scrape and clean any excess glue off and put back in the rack. When their respective sides come along they will be joined together.

2. Bob has been busy bringing tops and backs up to speed.

3. Bob is setting up and gluing back braces in this photo. To the left of it is one drying.

4. Tops and backs have been relaxing in the climate room for 72 hours. These two have just been braced.

2. This frame is ready to move to the climate room.

3. Luis has just kerfed this frame and is now cleaning up inside before sanding the head and tail blocks.

4. A couple of frames next in line for kerfing.

The first all mahogany set has had the top lasered. Next the back. An initial hole in the center of the rosette helps guide the rosette cutter and keeps it centered.
