Further commentary from 84 Engineering, the designers and manufacturers;
RIGID
The Gibson 72" grinder body and stand start life as 6mm Australian-made sheet steel. The components are precision laser cut before being assembled with more than 35 seam welds. Weighing in at over 85kg, the Gibson 72 is one of the most rigid and stable platforms on the belt grinder / linisher market. This mass and rigid construction not only ensures accuracy and perfect alignment in all grinding / linishing scenarios, but makes for a smooth & vibration-free experience.
The auxiliary components and attachments on the Gibson 72 maintain this extra-engineered philosophy and premium build quality. The 40x40mm tooling arms, single-piece tension mechanism and over-sized tracking knob are CNC machined from 6061 aluminium. The ergonomic tension handle and rotating platen-support are laser cut from 12mm plate steel, and 25mmØ tooling spigots and the platen rotating/indexing mechanism are turned from stainless steel bar, making for a bullet-proof platform.
 
VERSATILE
Included with every Gibson is a small wheel rest, 300x150mm chamfered angle-adjustable work rest, small wheel idler arm, ¼”, ½”, ¾” & 1” (6mm, 13mm, 19mm & 25mm) small wheel sets, and an extremely versatile rotating platen.
Loosen the locking handle by hand and rotate the entire platen assembly to access 7 separate grinding setups! Utilise 2 x 2”, a 3” and a 5” contact wheel, a hardened 215mm D2 flat platen and 3 different slack belt lengths without removing a tool arm! For ease, the platen assembly includes a spring-loaded indexing pin that has 12 locking positions at 30-degree intervals.
Platen support design  allows for excellent access on either side of the flat platen or contact wheels for un-interrupted grinding of edges, reliefs and awkward work pieces. The in-built tilting stand allows the grinder to be used in both vertical and horizontal orientations.
 
POWERFUL
The Gibson 72” belt grinder will plug into any standard 230/240v 50Hz 12A power socket. The Variable Frequency Drive (VFD) is IP66 outdoor rated water/dust proof enclosure and converts power to 3-phase driving the 1.5kw (2hp) 4-pole motor. This powerhouse spins a high-traction 7” drive wheel to generate a maximum belt speed of 5000 surface feet per minute. You can hog material at an epic rate or run the belt slowly enough for fine shaping, sharpening and polishing – the infinitely variable speed controller provides maximum torque throughout the speed range.
 
URETHANE WHEELS
All contact wheels on the Gibson 72” linisher are precision CNC machined from 6061 billet aluminium and coated in our newly formulated abrasion-resistant urethane rubber. Rubberised wheels make for quieter operation and even out belt discrepancies, meaning you will not experience any ‘jitter’ or ‘bounce’ through the contact wheels.
 
DRIVE WHEEL TRACKING
The Gibson belt grinder uses a unique drive-wheel tracking system whereby the whole motor mount tilts to adjust belt alignment. This design offers superior tracking characteristics, maintaining alignment under heavy loads and varying belt tensions in forward and reverse.
 
INFINITE BELT TENSIONING
The grinder tensioning mechanism uses a combination of acetyl bushes and a cam mechanism to easily and infinitely adjust your belt tension to suit the job. This feature comes in especially handy for using slack belts, and makes belt changes a quick, single-handed operation.
 
COMPATIBILITY
The Gibson is compatible with the Surface Grinder Attachment and most others found in the 84 Engineering Section.
