Step 8: Mass Production
Here you can see my belt sander mounted upside-down on my workbench (holes drilled in the table and wire used to tie the sander handle down). A tool rest surface is held by my vise to rest a special sanding guide tool on. To keep plastic dust from getting sucked into the motor, a PVC pipe hood extends the air intake away from the sanding action.
Since the metal guides on my tool are not perfectly shaped, I usually have to do a little hand sanding after the power sanding. Even so, the power sanding saves a whole lot of time when you are making hundreds of tootophones.
