Disc Sander

Booth & Blades Disc Sander
Machine Workshop (Room G24)
Level 03 - Machine Certification


The sander uses a rotating disc of sandpaper to smooth surfaces of various materials through abrasion. The material is held against the sandpaper which slowly erodes the rough surfaces leaving a smooth and consistent finish. Different grades of sandpaper can be used to achieve different results. The Sander can also be used to improve the flatness of a surface in a technique known as linishing.

Health and Safety

  • The disc sander is a power tool that has the potential to cause serious injury if used incorrectly. Always exercise extreme caution when using the equipment. NEVER touch the machine or other moving parts during use.
  • Familiarise yourself with the emergency stop buttons on the machine. Always turn the machine off when not in use. NEVER leave the machine unattended while in use.
  • Ensure the dust extractor gate is opened before use and closed when finished.
  • Keep material in contact with table or fence.
  • Only sand on the RIGHT side of the disc ie the down stroke. DO NOT sand on the left side hand side of the disc.
  • Do not sand unsupported material or painted/finished timber.
  • Do not wear loose articles of clothing and/or jewelry when operating the sander.
  • Please see workshop staff if there are any issues with the machines operation. Please do not attempt to make any adjustments without prior approval.

Operation Instructions

  • Turn on dust extractor: Turn on dust extractor and open the dust extractor gate.
  • Prepare the workspace: Ensure the workplace is clear. See a staff member to unlock the machines power.
  • Machine material: Turn on the sander and begin sanding the material. Only sand on down stroke with the disc in a smooth and controlled motion.
  • Shut down and Remove material: Use the mushroom switch to turn off the machine. Remove the material and clear away any dust and offcuts from both the machine and floor. See a workshop staff member to lock the machines power.

Workmanship Considerations

  • Don’t attempt to sand the material too quickly by applying heavy pressure to the workpiece. It is best to go slow and steady.
  • There are different grades of sandpaper which have different levels of coarseness known as grit. The lower the number the coarser the sandpaper will be. For rough jobs (such as removing paint) you want to use a coarse sandpaper. For more delicate work choose a finer grit.
  • When sanding down rough wood, begin with a coarse sandpaper and gradually move through finer grits to something very fine (200 grit or more) to give a silky finish.
