I love tools—I’ve got boxes of them in my shop and in my home. My wife chuckles and shakes her head, I’m sure, because there’s a tool kit in almost every room of our house. Every new job I take on is an opportunity to acquire a new wrench, cutter or crimper. Punches, files, clamps and drills fill my heart with joy. Pantographs, saws and shapers fill my workspace with lovely dust.
As much as I adore specialized tools—the ones that do one thing and one thing only—measuring tools, that I use every day, or even every hour of every day are my bread and butter. Rulers, scales, micrometers, depth and diameter gauges. These are the implements needed to navigate the complexities of building something to close tolerances—like a guitar. But by far the most versatile of this class of tools is the dial caliper.
I’ve had my Brown & Sharpe dial calipers since the late 1970s. The corners and edges of the mahogany case have been rounded off from three decades of constant use, and the mahogany itself is darkened from oxidation and the oils from handling. If you look closely, you can see the impression from the serial number stamp in the wooden case. Steve Ward and I used those calipers to build the original five-neck guitar and the twin necked “Uncle Dick” for Rick Nielsen. I used them to plot the original design for the sustain block bridge and world’s first 12-string bass. They were there to measure neck dimensions on KK Downing’s Flying V and Glenn Tipton’s SG when designing their signature models in 1984. Gary Moore and I used them to measure the neck width and depth of Peter Green’s Les Paul ’Burst.
Almost every person of note who worked at Hamer handled this tool at one time or another. It’s is still insanely accurate and one of my most treasured possessions, and as much as I enjoy the new digital calipers that can add, subtract and convert to metric at the touch of a button, there is something satisfying about using the analog version. It’s a connection to something deeper than just the job at hand.
