Great Planes Rapture 40 - GPMA0220 - Manual (Page 5)

Building Board (GPMR6948) is suggested. A piece of 2' x 4'
[610 x 1220mm] Celotex
® ceiling tile is also suitable. Of
course, the building board won’t be flat unless the
workbench beneath it is flat as well.
• 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" [20mm]
This is a number six screw that is 3/4" [20mm] long.
Machine screws are designated by a number, threads per
inch, and a length. SHCS is just an abbreviation for “socket head
cap screw” and that is a machine screw with a socket head.
For example 4-40 x 3/4" [20mm]
This is a number four screw that is 3/4" [20mm] long with
forty threads per inch.
• 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 written 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, the
instructions will make a recommendation.
• Whenever just epoxy is specified you may use either
30-minute (or 45-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.
• Photos and sketches are placed before the step they
refer to. Frequently you can study photos in following steps
to get another view of the same parts.
• Not all die-cut parts have a name, or their complete
name stamped on them, so refer to the “Die-Cut Patterns”
on page 6 for identification. When it’s time to remove the
parts from their die sheets, if they are difficult to remove, do
not force them out. Instead, use a sharp #11 blade to
carefully cut the part from the sheet, then lightly sand the
edges to remove any slivers or irregularities. Save some of
the larger scraps of wood.
