A well-maintained wood throughfeed moulder will produce consistent, glue-line quality finishes for decades. A poorly maintained one will cost you in burned parts, chatter marks, snipes, and eventually unplanned downtime as spindle bearings fail or drive components wear out prematurely. The two biggest drivers of long-term reliability on any through feed moulder are consistent lubrication […]
Consistent veneer splicing quality depends on two things working together: a properly adjusted splicer, and a maintenance program that keeps every moving part running clean and true. Missed lubrication intervals show up quickly as increased chain wear, feed roll drag, and heater bar misalignment — all of which translate into overlapping joints, mismatches, and burning […]
A disciplined straight line rip saw maintenance program is what separates a saw that delivers glue-line quality cuts for thirty years from one that’s burning material and producing un-square edges inside of three. Every defect we cover in our straight line rip troubleshooting guide — erratic cuts, no glue joint, edges not square, wedges — […]
A through feed moulder is one of the most complex machines in a rough mill — each spindle, cutterhead, guide, feedroll, and holddown has to work in precise coordination to produce a clean, square, chatter-free finish. When something goes wrong, the symptom usually looks like a finish defect, a feeding issue, or a snipe on […]
The Mereen-Johnson Rip Navigator Tracker is the automatic infeed system that feeds boards from a hopper through a board dealer, stops, and pinch rolls onto the chain that carries them into the rip saw. When the Tracker stops feeding cleanly — whether it’s double-feeding, feeding unevenly, or dragging boards on the chain — the root […]
Consistent lubrication is the single most important preventive maintenance task on the Mereen-Johnson Rip Navigator Tracker automatic infeed system. The Tracker’s bearings, pivot points, linear guides, and gearboxes all rely on proper greasing intervals to maintain smooth, accurate feeding — and when lubrication is skipped or over-applied, bearings run hot and premature wear follows. This […]
Proper lubrication is the foundation of long-term tenoner maintenance. Bearings that run too dry wear out prematurely; bearings that are over-greased run hot and fail even faster. Arbor bearings in particular require precise greasing intervals, exact quantities, and active temperature monitoring to deliver the decades of reliable service that a Mereen-Johnson tenoner is designed for. […]
View PDF The Mereen-Johnson Scout Deck is the lumber scanning and feed-prep component of the Rip Navigator optimization system — measuring board width, length, and crook before each piece is fed onto the Tracker conveyor and into the rip saw. When the Scout Deck stops feeding cleanly, it’s almost always a mechanical issue in the […]
View PDF The Mereen-Johnson Scout Deck is the lumber scanning and feed-prep component of the Rip Navigator optimization system — measuring board width, length, and crook before each piece is fed onto the Tracker conveyor and into the rip saw. Consistent Rip Navigator maintenance on the Scout Deck protects both the scanning accuracy and the […]
View PDF The Mereen-Johnson Power Table is a feed-assist material handling table that helps operators load lumber into your rip saw — reducing operator fatigue, improving feed consistency, and protecting throughput across long production shifts. Like every chain-driven machine on a rip line, the Power Table relies on consistent power table lubrication to maintain smooth […]
