Disc
Sander Speeds
Before
you begin any disc sanding operation, set the Mark V to run
at the correct speed. To do this: turn the machine on, turn
the speed dial to the correct speed and let the disc come
up to speed.
The operating
speeds for disc sanding are determined by the grit you're
using and the material you're sanding. Generally, you can
use faster speeds on softer woods. Faster speeds will also
give you a smoother finish. Slower speeds reduce the risk
of “burning” the workpiece and are better for sanding
away large amounts of stock.
To help
determine the right speed for the job, use Table 17-1. A good
rule of thumb is: The softer the material or the finer the
grit, the faster you can run the sander. However, don't run
the sanding disc too fast or the wood may heat up and burn.
