The application of the sandpaper strip is shown
in fig. 57. Care must be exercised in order to
prevent dubbing the corners of beads, shoulders
etc. It is good practice to finish sanding with
the work in reverse rotation. This is particularly
true when sanding basswood, white pine and
mahogany. These woods are hard to sand
clean since sanding packs the surface fuzz
down to the wood. Sanding very lightly, and
not too long with the lathe reversed, will lift the
fibres and cut them off cleanly.
2. USE OF SANDING DISCS
A fully adjustable sanding table adds to the
scope and convenience of sanding operations.
Sanding is always done on the down travel side
of the wheel working on the other side would
kick the work upwards. Either second or third
speed can be used.
SANDING, BUFFING AND POLISHING
1. USING THE LATHE TO SAND TURNINGS
Turnings should be sanded with the lathe running
in second lowest speed. A large sheet of
sandpaper is useful for smoothing cylinders. All
other sanding operations are done with a
narrow strip of abrasive paper. The best finishing
grit is 3/0 for soft wood, 4/0 for hard woods. Worn
2/0 paper is often used, and is the equivalent of
3/0 or 4/0 new paper.
The sanding disc is a metal plate with a threaded
shank which fits the end of the lathe spindle.
Abrasive paper is glued to the machined
surface of the plate by means of a quick drying
cement supplied for this purpose. Abrasive discs
can be purchased or cut from the standard sizes
of abrasive paper.
3. USE OF SANDING DRUMS
Standard sanding drums are usually r ubber
cylinders which can be expanded to hold an
abrasive sleeve in place. Similar cylinders turned
on the lathe and covered with abrasive paper
