The machines are replacing themselves: string pinsetters and self-diagnosing equipment are deliberately engineered to eliminate the full-time mechanic. The trade shrinks to a regional service tech who visits several houses — and even that circuit is thinning.

Our AI replacement risk score — how we score jobs
A traditional bowling alley mechanic tends free-fall pinsetters — Brunswick A-2s and AMF 82-70s, machines designed in the 1950s with thousands of moving parts that jam, shear pins, and eat belts nightly during league play. The job is fast diagnosis behind the curtain: clearing a 180 stop, re-timing a table, rebuilding distributor assemblies, plus maintaining lane machines that oil the lanes, ball returns, and scoring systems. A busy house historically needed a mechanic on shift every league night.
The industry found its answer, and it isn't a robot fixing the A-2 — it's removing the A-2. String pinsetters, where pins dangle on cords and reset by winch, have swept new installations and conversions because they have a small fraction of the moving parts, sip electricity, and rarely need attention; sanctioning bodies now certify league play on them, which removed the last excuse. Modern scoring and management systems self-diagnose and phone the vendor. Boutique bowling-entertainment venues are built around string machines with no mechanic position budgeted at all. Each conversion quietly deletes a full-time trade job that took years to learn.
What remains: thousands of legacy houses still run free-fall machines and will until the conversion loan pencils out, and those machines need exactly the old skills — an A-2 does not fix itself. String machines still tangle cords and need periodic service, so regional multi-house technician routes are the emerging model. Our 72 reflects a trade being obsoleted by product design rather than AI per se: the knowledge stays valuable in a market that keeps shrinking underneath it.
Automatability: our editorial assessment of current and near-term AI capability
The conversion wave is rolling now: string pinsetters dominate new builds and retrofits, and every conversion eliminates most of a full-time position. Through 2030 expect on-staff mechanic jobs to keep disappearing into regional service routes and vendor contracts. Legacy free-fall houses provide a long tail of work for veteran mechanics — a tail that shortens with each center that converts or closes.
They're getting rid of the machines that needed them. String pinsetters have a fraction of the parts of free-fall machines, cut energy and maintenance costs dramatically, and are now league-certified. When a center converts, the full-time mechanic position usually converts too — into an occasional service visit.
Yes, in two places: the thousands of legacy centers still running Brunswick and AMF free-fall machines, which need traditional skills nobody teaches anymore, and vendor service networks maintaining string machines across many locations. Both favor experienced techs willing to travel; neither supports many one-building, full-time positions.
Nearest neighbors first: amusement and arcade equipment, vending systems, commercial kitchen equipment, or facilities maintenance — all reward the same diagnose-and-fix-under-pressure skill set with bigger markets. Within bowling, string-machine certification plus scoring-system IT skills makes you the regional tech the industry actually still hires.
Longer than vendors would like — a paid-off A-2 that a veteran keeps running beats a six-figure conversion for many family-owned centers. Expect a substantial legacy fleet into the 2030s, shrinking with each renovation or closure. That's a real runway for existing experts, and a poor bet for anyone entering the trade now.
