Handheld Sander Introduction

From CoMakingSpace Wiki

This is the content required for an introduction to our handheld sanders - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)

This introduction is valid for the following machines:

If you need this introduction, please reach out to the following tutors: Lukas, Johannes, Keno, Martin, Patrick, Luzian, Sebastian, Jakob, Luca.

Let's begin! First off, make sure you have read the machine's wiki page and manual (should be linked from its wiki page).

Safety

Personal protection: Protection - breathing.svg

+ when working with metal or small workpieces: Protection - goggles.svg

ear defenders and gloves are also recommended when working with a sander (and shop vac) for an extended amount of time

Dangers Precautions
lots of fine dust from wood or plastics - can irritate lungs and skin
  • wear a dust mask and long clothes if your material generates hazardous dust
  • check for a clean run and fit of the sanding medium before you start; check if hole alignment for the dust extraction is correct
  • sand outside if you can't connect a shop vac or fine filter
  • do not blow the workpiece clean when you're done, best clean it with a moist towel
sparks from sanding metal
  • when sanding metal, do NOT connect dust collection - the sparks could cause a fire!
  • wear goggles when working with metal
powerful movements can make the workpiece shift (or fly!) and let a handheld sander "run away"
  • wear goggles when working with small workpieces
  • secure your workpiece and exert a firm grip on the tool
  • let the tool get to full speed before contacting your workpiece and start with light pressure
    • exception: eccentric sanders only work correctly when under load and may leave marks if you lift and lower them while running - they are best started on the workpiece [1] & HolzWerken 115
Danger - sudden start.svg
some of the sanders have no prevention of turning on after loss & restoration of power (keine Anlaufsicherung)
make sure the tool is turned off before plugging it in

Protect the Velcro

WRONG!

Do NOT sand with parts of the velcro pad uncovered - this will wear it out and lead to much poorer bonding of the next piece of sandpaper!

Suggested Reading

Besides these safety notes, you should read the page about dust to get a better conception of the dangers associated with some materials! Remember, you are responsible for the material you choose and for protecting yourself.
