He takes the rough pickguard and sticks it to a simple shaper template, and
runs it on the pin router. |
 |
He bevels the edge. |
 |
Sands and fairs the bevel. |
 |
Finally, he buffs the pickguard to a high shine. Another Collings guitar has made
it through the incredible gauntlet of operations and inspections! |
Mandolins:
|
Not a full exposé, but some cool pictures. |
 |
Mandolin production is the newest enterprise at the Collings factory. |
 |
CNC fixturing is just as important in the mandolin section. |
 |
All of the mandolin tooling is bright and shiny, because it's mostly quite
new. |
 |
Vacuum chucks for fingerboards |
 |
Vacuum chucks for peg heads |

A tiny go bar deck for a tiny body. |
 |
Check this out. It's a real pain to fit those curved top braces to a curved
top. |
 |
Not so, if you make BOTH on CNC equipment. |
 |
Here a billet of spruce is precisely machined to fit to the curve of the mandolin
top. It's a snap to rip out a couple of perfect braces from this piece. |
 |
A simple jig locates the braces. |
 |
There are only two top braces inside a mandolin. |
 |
The mandolin side bending rig. |
 |
This is clearly the direction that the guitar side bender will take. |
 |
Spring clothes pins fit the smaller linings of a mandolin. |
 |
Neck and end blocks, also made on CNC, are glued at the same time. |
 |
Sides are held in CNC made phenolic and aluminum molds. |
 |
Check out this bit of binding. Rather than assembling and mitering, the entire
outline was cut from a solid piece of ivoroid. No sweat, if you happen to have your
CNC programmed to cut the peghead veneer, too. |
 |
More CNC parlor tricks. The end of the bound fingerboard is undercut on the
CNC. |
 |
And, sheets of laminated ivoroid are cut to match. |
 |
Look at this little piece. |
 |
Here's the back side. |
 |
Simply snap in place. |
 |
And you get a terrific look of binding and purfling. |
 |
This is the cantilever support for the fingerboard as it hangs over the body.
Only Collings makes this out of one piece. |
 |
A tricky little CNC-cut piece of ivoroid goes in here. |
 |
To complete the top binding. If you're not into mandolins, you may not recognize
this piece. Take my word for it, it's way cool. |
 |
This next CNC trick is just plain not fair. Strips of laminated ivoroid are
sliced on the machine. |
 |
And, a tiny 0.020" cut is made along the length of each strip. |
 |
Into that strip fits a 0.020" black strip, forming the most perfect laminated
binding, with built in side purfling! |
 |
And, that nasty piece around the "button" of the heel. Why not make
it of solid ivoroid with an inlay, so you don't have to bend it either? Why not,
indeed. |

Collings mandolin #1. |
 |
A laser. Any good mandolin maker needs a laser. Oh yeah. |
 |
Secrets, posted on the wall. |
 |
A finished mandolin. Yep, they really are finished completely, just like this,
before the holes are cut. |
 |
And, wouldn't you know it, they're cut on the laser! Now, that's really
not fair. When the laser cuts the f-holes, it doesn't crinkle the finish in the slightest,
and it also burnishes the edges of the holes, so there's no cleanup to do at all. |
