Dynaflite PT-19 - Manual (Page 4)

A flat, durable, easy-to-handle sanding tool is a
necessity for building model airplanes. Great Planes
makes a complete range of Easy-Touch'" Bar Sanders
and replaceable Easy-Touch adhesive-backed
sandpaper. On our workbench, we have four 11"
Easy-Touch Bar Sanders, equipped with #50, #80,
#150 and #220-grit sandpaper. This setup is all that is
required for almost any sanding task. Custom sanding
blocks can be made from balsa for sanding hard-to-
reach spots. We also keep some #320-grit wet-or-dry
sandpaper for finish sanding before covering.
For future reference, here's a list of Easy-Touch Bar
Sanders and adhesive-backed sandpaper:
5-1/2" Bar Sander (GPMR6169)
11 "Bar Sander (GPMR6170)
22" Bar Sander (GPMR6172)
12' Roll of adhesive-backed sandpaper,
80-grit (GPMR6180)
150-grit (GPMR6183)
220-grit (GPMR6185)
Assortment pack of 5-1/2" strips (GPMR6189)
IMPORTANT: During construction you will be using a
number of balsa sticks to frame various assemblies.
Ample material is included but you should study the
plans, then make an effort to cut the longest pieces
you will need first. Label the pieces as you cut them
for later reference. By doing this now, you won't
have to splice pieces together later.
This kit is built with three types of glue.
Cyanoacrylate: CA glues cure almost instantaneously
and are moderately strong. There are different
viscosities of CA's intended for different conditions
you will encounter when you build. Thin CA is great
for "tack-gluing," for glue joints that fit well and for
parts that are already joined but need to be
permanently bonded. Medium CA is used for general
construction where you apply glue to one part, then
join it to another part. Thick CA is great for glue joints
that don't fit perfectly or parts that require a little time
for positioning before the glue cures. You will
encounter many other conditions that require one or
the other types of CA.

Always use CA in a well ventilated area. Open some
windows or place a fan in the room to circulate the
air. Do not lean directly over your work when you
use CA and look away while it cures or "sets off."
CA can cure immediately upon contact with skin so
if you accidentally bond your fingers, do not use
vigorous motion to separate them. Use CA Debonder
(GPMR6039) or acetone (nail polish remover) or
soak your fingers in warm water for a few minutes.
