Creating flat, straight surfaces is crucial in the quest to build elegant projects. Virtually all forms of joinery and the tools that cut them depend on straight edges and square cuts. The POWERMATIC 54A/54HH 6” Jointer makes it easy to achieve the high levels of accuracy you need in this always-crucial operation. Base Cabinet The 21”-wide by 13”-deep all steel base cabinet provides stable footing for the POWERMATIC 54A/54HH 6” Jointer and puts the table surface at a comfortable 32” above the floor. The all-steel base cabinet not only provides stable footing for the jointer, it houses the motor and dust collection outlet. The 1 HP, 1Ph, 115/230V motor (pre-wired 115V) is factory-mounted within the base cabinet and can be converted to use 230V power should that be desirable. The motor is on a special mount within the base cabinet that allows the user to adjust belt tension should that become necessary. The base also contains the dust collection chute that evacuates debris from below the cutterhead. The chute guides that debris to the exterior 4”-diameter port near the floor. Locating the outlet port near the floor helps keep the hose out of the way and puts it at a similar height as the inlet of our popular dust collectors such as the PM1300. 3-Knife Cutterhead (54A Model) The 54A cutterhead (top in this photo) features our Quick Set knife system that uses cams to position the knives precisely so they cut smoothly and work together equally to disperse wear. The POWERMATIC 54A Jointer features a 3-knife cutterhead fitted with adjustment cams that make setting critical knife height easy and extremely accurate. Each knife is 6 1/16”-long, .”-tall and 5/64”-thick and made from high quality steel. The knives are secured by a set of 4 gib screws and a gib plate. Below each knife are two adjustment cams. The included manual provides complete instructions (with illustrations) that make changing and setting the knives easy. They even show how to offset one or more of the knives for cutting small rabbets or to compensate for small nicks in a knife. Helical Cutterhead (54HH Model) There are many cutterhead designs that carry the helical moniker, including simple straight blades broken into segments and dispersed around the cutterhead cylinder. However, despite the name, they retain many of the liabilities of the long blade designs. While designing the POWERMATIC 54HH 6” Jointer we wanted to incorporate the performance of a true segmented, shear-cutting helical head. The helix head (right side of the image) uses full carbide inserts that greatly extend durability as well as the quality of the cut. Sound is also drastically reduced over nearly all other cutter configurations. The helical cutterhead is so effective because its carbide inserts are arranged in spiral-shaped rows. The inserts have a 4” radius ground into them and are mounted so they approach the wood at a 14-degree angle. That creates a true shear cut that eliminates much of the impact and the resulting fiber disturbance other cutterhead designs deliver to the wood. The helical cutterhead cuts so efficiently that it dramatically reduces the noise made when cutting wood. In fact, it is so quiet, new POWERMATIC 54HH 6” Jointer users often think it is not cutting wood at all, until they see the results. The shearing effect of the helical cutterhead produces a remarkably smooth surface on even heavily figured wood. The helical cutterhead inserts are precisely machined from solid high-grade carbide, each with four identical cutting edges. If an edge eventually goes dull, you simply index it to the next cutting edge! Each insert has a marking at one edge that makes indexing all or any number of them the same way very easy, though needing to do that is unlikely. Because the inserts themselves and the seats into which they fit are so precisely machined, there is no adjustment or “fitting” necessary. Indexing or replacing an insert takes just seconds. Simply loosen its retaining screw, turn the insert to its new position and tighten the screw. The infeed table height adjustments are truly u...
