When production demands outgrow the capabilities of a single straight-line ripsaw, manufacturers have two options: they can add more straight-line ripsaws, with additional labor required, or upgrade to a gang ripsaw. The latter is usually recommended, and manufacturers typically start off with a 12-inch width capacity gang rip with fixed blades on the arbor. Read […]
This article explores the efficiency and yield improvements achievable in rough mill operations through strategic selection of ripsaw equipment. It discusses the transition from traditional straight-line ripsaws to gang ripsaws, emphasizing their ability to process significantly more material with the same labor input while delivering precise, parallel strips.

This article discusses strategies for wood product manufacturers to enhance efficiency and profitability in their rough mill operations. Highlighting the current favorable market conditions and challenges like rising labor costs, it emphasizes the financial impact of optimizing lumber yield. It explores the benefits of moving blade gang ripsaws, which minimize changeover times and maximize yield […]
This video demonstrates the potential dangers when anti-kickback safety features are disabled, missing, or not properly maintained. You’ll see a vivid illustration of the serious impact kickback can have on a rip saw. Mereen-Johnson has developed a controlled method to simulate kickbacks on any rip saw, helping to underscore the importance of these critical safety […]
Consistent rip saw maintenance is what keeps a Mereen-Johnson Select Rip Saw producing glue-line quality cuts and meeting its full 24-hour-shift duty cycle. On a moving-blade Select Rip Saw — with multiple shifting saw assemblies, an air-actuated arbor brake, anti-kickback finger systems, and integrated laser alignment — that maintenance program touches more components than on […]
Even a well-built rip saw needs periodic rip saw calibration to stay within factory tolerances. Wear accumulates, lasers drift slightly, chain race tracking shifts under heavy production, and small alignment changes start showing up as visible cut quality issues — un-square edges, no glue joint, snipe, wedging. Calibration is what brings the machine back to […]
The Mereen-Johnson Rip Navigator is a complete rip optimization system — the Scout Deck scans each board for width, length, and crook, the Tracker conveys boards from hopper through to the saw, and the Rip Navigator software and controls turn scanning data into optimized cut decisions. The system delivers up to 20 boards per minute […]
The Rip Navigator 4.0 software is the brain of a Mereen-Johnson automated rip saw line. It takes scanning data from the Scout Deck — board width, length, and crook for every piece of lumber that enters the system — and turns it into optimized cut decisions that the rip saw executes in real time. Knowing […]
In this video, we’ll showcase Mereen-Johnson’s TwistLock Blade Setting System — the industry’s fastest fixed blade positioning system. This innovative design allows you to position blades individually, enabling single-pocket changes without disrupting the balance of your arbor setup. Why TwistLock Changes the Economics of Blade Changeovers On a traditional fixed arbor rip saw, changing a […]
Knowing how to change rip saw blades safely and efficiently is one of the highest-leverage skills on a Select Rip Saw operation. Every minute of unplanned blade-change downtime is a minute the line isn’t producing — and a tooling change done incorrectly can damage the arbor, throw off blade positioning, or create safety risks on […]
A successful rip saw installation sets up everything that follows — accurate cuts, smooth feeding, full duty-cycle performance, and a clean handoff from machinery delivery to production. The work splits naturally into two phases: the preliminary placement, alignment, and anchoring that your facility team can handle before your Mereen-Johnson technician arrives, and the commissioning, calibration, […]
