3 inch Spindle Assembly for JBOS-5 gives the JET JBOS-5 spindle sander a dedicated 3 inch spindle sized for sanding larger curvatures, so curved workpieces can be shaped with better control along broader arcs. This JET Tools spindle assembly is identified as manufacturer part JT9-709534, which ties it directly to the JET 709534 spindle assembly specification for consistent matching on the JBOS-5 machine. The part is described as JBOS-35A 3 inch spindle assembly, which clarifies that this single 3 inch spindle is configured for the JBOS-5 system rather than a different JET platform. With a listed height of 3 inches, the spindle provides a vertical sanding area that aligns with the stated curvature use, helping operators present taller work along the abrasive surface. The 5.1 lb weight reflects a solid assembly, which supports stable sanding contact during extended shaping.
This JET Tools spindle assembly is designated specifically for use with the JET JBOS-5 spindle sander, so its interface and proportions are set up around that machine's spindle system for direct installation. The 8 inch length and 3 inch width dimensions describe the overall footprint of the assembly, which affects how the spindle is maneuvered into position on the sander and onto the storage rack between tasks. With a 3 inch height listed, the sanding area stands tall enough to work larger curvatures while still remaining manageable for typical JBOS-5 table settings. The 5.1 lb weight gives the assembly a substantial feel when lifting it, which aids steadiness as the spindle is carried to and from the machine for changeovers.
This 3 inch spindle assembly for JBOS-5 is identified as being for use with JET's JBOS-5 spindle sander, so it is oriented to shops already operating that specific machine. The stated compatibility with the JET JBOS-5 spindle sander ties the assembly to that platform for sanding operations that rely on spindle changes rather than separate machines. With a single 3 inch spindle provided, this assembly is directed toward sanding larger curvatures where a wider diameter contacts more of the workpiece edge in one pass. That 3 inch height works with the larger diameter to present a taller sanding surface, which is useful when shaping thicker stock or extended curved profiles along templates. The JBOS-35A 3 inch spindle assembly designation groups it with JET's organized spindle options, giving shops a clearly marked size when setting up repeat jobs that call for this diameter.
The JET Tools spindle assembly is listed with a length of 8 inches, which defines how far the body extends as it is guided into place on the JBOS-5 spindle sander for each changeover. A 3 inch width pairs with that length to describe the side-to-side clearance needed around the spindle, which matters when the machine is positioned near other tools or benches. The 5.1 lb weight means the assembly sits with noticeable mass once installed, helping it stay steady under normal sanding pressure in repeated passes. Because it fits conveniently on the storage rack, the spindle can occupy a defined spot on the JBOS-5 itself between uses, supporting a consistent workflow when switching between different spindle sizes during production or fitting work. The part identification as JET 709534 and JT9-709534 gives a stable reference for technicians who want the same spindle geometry every time they reorder or standardize setups.
The 3 inch spindle assembly is for use with JET's JBOS-5 spindle sander, so it is intended to work on that specific JET JBOS-5 platform.
The 3 inch spindle is stated as for sanding larger curvatures, giving a wider diameter that tracks smoothly along broad arcs on curved workpieces.
The 3 inch height defines the vertical sanding area, allowing taller sections of curved material to contact the abrasive surface during shaping.
The assembly fits conveniently on the storage rack, so it stays on the JBOS-5 sander between tasks for faster spindle changes during ongoing jobs.
The spindle assembly lists a height of 3 inches, a length of 8 inches, and a width of 3 inches, defining its footprint for handling and storage.
The 5.1 lb weight indicates a solid spindle assembly, which helps it sit steadily on the JBOS-5 sander during normal sanding pressure.
The 3 inch Spindle Assembly for JBOS-5 from JET Tools combines a 3 inch height with a diameter specified for larger curvatures, so it suits curved work needing a broader sanding surface. Its compatibility with the JET JBOS-5 spindle sander and fit on the storage rack ties it directly into existing JBOS-5 workflows. With part numbers JBOS-35A 3 inch spindle assembly and JT9-709534, this spindle offers a clearly identified option when a 3 inch spindle is required for repeat sanding setups.
