Sherwood 12in Parallelogram Jointer - Spiral Head Fitted
www.timbecon.com.au/sherwood-...
In this episode of Rig Rundown, Jake takes us through this monster jointer, one stop short of industrial grade.
The new Sherwood 12 inch Parallelogram Jointer's performance improve greatly over its little brother, the wedge bed jointer, to the point where it now thoroughly competes with the best jointers on the market. Featuring a parallel bed design, more cutters and spirals, a much bigger motor and the Sherwood Five-Year Warranty, you won't find another 12 inch jointer with the same specs for this price.
What is a parallelogram jointer? What is the difference between it and a wedge/traditional jointer
The traditional jointer bed is attached to the body of the jointer via an angled dovetail. Thus as you move the beds down, the beds move further away from the cutting head. As you raise the beds, the beds move closer to the cutting head.
Parallelogram beds are mounted on a parallelogram so as you move the beds down or up the distance between the bed and the cutter head remains constant. This keeps clearance to a minimum for a better finish.
12 Inch Jointer with a one-piece welded cabinet base
The same welded one-piece cabinet base supports the jointer securely on the floor allowing for larger pieces to be pushed through the unit. The cabinet has a single 4in integral dust port for efficient waste extraction and it houses the powerful 3HP induction motor that drives the cutterheads.
The double tapered belt design is gone and in its place is a single wide poly-ribbed V-belt. These belts have better power transfer to the cutterheads, longer service life and allow for precision balanced alloy pulleys to be fitted - reducing inertia and improving smoother, quieter operation.
Japanese SKF Bearings on a low-friction spiral cutterhead
The cutterheads are now supported by large Japanese SKF bearings, again for smoother, quieter operation with lower friction - improving service life and performance. Due to the increased cutterhead diameter, it has allowed a better design of helical spiral head to be developed for better performance. Featuring 6 spirals and 52 knives this unit will not get bogged down by even the hardest of Australia Eucalyps.
The bed itself and matching bedway on the tables are precision-machined multiple times over a number of days to allow the cast iron to settle and stabilize, then once assembled - the tables are again machined and polished over days for the same reason - so that each jointer bed has perfectly matched in-feed and out-feed tables. With a 2200m length, this jointer will comfortably straighten work pieces up to 4.4m long.
Higher, longer, solid fences with foldable handwheels
The new design of this jointer features a longer in-feed fence. Many other brands seem to feature a longer out-feed fence, which makes little sense as once the work piece is beyond the cutter, a longer fence helps less and less. So we have decided to ask the manufacturer to extend the in-feed side of the fence. This allows for greater accuracy with longer work pieces.
