Powermatic 20" Extension Bed extends the working distance between centers on the Powermatic 4224B lathe by 20 inches, which allows turning of longer spindles or assemblies on the same machine without changing your basic setup. The extension mounts to pre-drilled holes in the end of the bed or on the leg, so it uses factory-located mounting points that keep alignment consistent with the original bed. When the extension is mounted down on the leg, it adds 24 inches to the diameter of the workpiece that can be turned, increasing the maximum turning diameter in that position for larger bowls or platters. The extension also has a tool rest post, which provides a support location for the tool rest in the extended area so cutting tools can be supported close to the work.
The extension mounts to pre-drilled holes in the end of the 4224B bed, so it ties directly into the factory-machined end for consistent bed height and alignment relative to the headstock. The same extension can mount on the leg, which changes the working position and increases the possible diameter of the workpiece by 24 inches when mounted down on the leg. Using those pre-drilled locations helps position the extension in a way that supports smooth tool travel from the main bed onto the extension surface. The integrated tool rest post on the extension gives the operator a place to locate the tool rest in either mounting position so the cutting tool can track along the extended work area.
The Powermatic 20" Extension Bed for 4224B, part number PM9-6294905, is used on the Powermatic 4224B lathe, which places the extension directly in line with that machine's bed. When the extension is mounted to the pre-drilled holes in the end of the bed, it becomes a continuation of the main lathe bed, giving an additional 20 inches of working distance between centers for spindle or between-center turning. In that position, turners can set up long workpieces, such as extended spindles or multi-part assemblies, within the combined bed length. When mounted down on the leg instead, the extension shifts the work zone vertically, which allows the lathe to handle workpieces with 24 inches more diameter capacity in that mounting configuration. The tool rest post that is part of the extension supports the tool rest in whichever of these positions is used, so the turning tools remain supported near the work along the extended bed.
The fact that the extension mounts to pre-drilled holes in the end of the bed means Powermatic has located those holes relative to the original bed ways, which supports accurate alignment between the existing bed and the extension. Using those fixed locations helps the extension line up so the tailstock and tool rest can travel from the main bed onto the extension without a step that would affect movement. Adding 20 inches to the working distance between centers allows longer turnings to be managed between headstock and tailstock, which reduces the need to reposition centers during a job and supports more consistent results along the full length. When mounted down on the leg, the 24-inch increase in diameter capacity changes the kind of work that can be handled, allowing larger diameter pieces to be turned in that area while still using the lathe's overall structure. The presence of a tool rest post on the extension gives a dedicated anchor point for the tool rest in the extended area, which helps the operator maintain stable tool support across the full added length or increased diameter zone.
The Powermatic 20" Extension Bed with part number PM9-6294905 is designed for the Powermatic 4224B lathe, which aligns the extension with that specific machine's bed.
The Powermatic 20" Extension Bed adds 20 inches to the working distance between centers, which allows longer workpieces to be turned between headstock and tailstock.
The Powermatic 20" Extension Bed mounts to pre-drilled holes in the end of the bed or on the leg, providing mounting options that use existing factory hole locations.
When the Powermatic 20" Extension Bed is mounted down on the leg, it adds 24 inches to the diameter of the workpiece that can be turned, expanding diameter capacity in that area.
The tool rest post on the Powermatic 20" Extension Bed provides a mounting point for the tool rest in the extended zone, supporting cutting tools close to the workpiece.
The pre-drilled mounting holes used by the Powermatic 20" Extension Bed align with factory locations on the 4224B bed or leg, supporting proper positioning relative to the main bed.
The Powermatic 20" Extension Bed for 4224B, part number PM9-6294905, extends working distance between centers by 20 inches and can also increase diameter capacity by 24 inches when mounted on the leg. Its mounting to pre-drilled holes on the bed or leg and integrated tool rest post tie the extension into the existing Powermatic 4224B layout. For shops using this lathe that need greater length or larger diameter capacity in a controlled way, this dedicated extension bed provides that added capability within the same machine footprint.
