and replaceable Easy-Touch Adhesive-backed
Sandpaper. While building the Giant F4U Corsair we
used two 5-1/2" Bar Sanders and two 11" Bar Sanders
equipped with 80-grit and 150-grit Adhesive-backed
Sandpaper. Here’s the complete list of Easy-Touch Bar
Sanders and Adhesive Backed Sandpaper.
5-1/2" Bar Sander (GPMR6169)
11" Bar Sander (GPMR6170)
22" Bar Sander (GPMR6172)
33" Bar Sander (GPMR6174)
44" Bar Sander (GPMR6176)
11" Contour Multi-Sander (GPMR6190)
12' rolls of Adhesive-backed sandpaper:
80-grit (GPMR6180)
150-grit (GPMR6183)
180-grit (GPMR6184)
220-grit (GPMR6185)
Assortment pack of 5-1/2" strips (GPMR6189)
We also use 320-grit (MMMR1204) and 400-grit
(MMMR1202) wet-or-dry sandpaper for finish sanding.
IMPORTANT BUILDING NOTES
•
There are two types of screws used in this kit.
Sheet metal screws are designated by a number
and a length.
For example #6 x 3/4" [19.1mm]
Machine screws are designated by a number,
threads per inch and a length.
For example 4-40 x 3/4" [19.1mm]
•
When you see the term test fit in the instructions, it
means that you should first position the part on the
assembly without using any glue, then slightly modify
or custom fit the part as necessary for the best fit.
•
Whenever the term glue is used you should rely upon
your experience to decide what type of glue to use.
When a specific type of adhesive works best for that
step we will tell you what type of glue to use.
•
Whenever just epoxy is specified you may use either
30-minute epoxy or 6-minute epoxy. When 30-minute
epoxy is specified it is highly recommended that you
use only 30-minute (or 45-minute) epoxy because you
will need the working time and/or the additional strength.
•
Occasionally we refer to the top or bottom of the model
or up or down. To avoid confusion, the top or bottom of
the model is as it would be when the airplane is right
side up and will be referred to as the top even if the
model is upside down during that step, i.e. the top main
spar is always the top main spar even if the wing is
upside down when you are working on it. Similarly,
move the former up means move the former toward the
top of the fuselage even if the fuselage is upside down
when you are working on it.
•
When you get to each step, read that step completely
through to the end before you begin. Frequently there
is important information or a note at the end of the step
that you need to know before you start.
•
Photos and sketches are placed ahead of the step
they refer to. Frequently you can study photos in
following steps to get another view of the same parts.
