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" [1.91mm]
Machine screws are designated by a number, threads per
inch, and a length.
For example 4-40 x 3/4" [1.91mm]
• When you see the term “test fit” in the instructions, it
means 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. Do not glue until
told to do so.

Important Building Notes
Optional Supplies and Tools
Great Planes Easy-Touch Bar Sanders are made from
lightweight extruded aluminum and can be found at most
hobby shops. They are available in five sizes.
5-1/2” (GPMR6169) for those tight, hard-to-reach spots;
11” (GPMR6170) for most general purpose sanding;
22” (GPMR6172), 33” (GPMR6174) and 44” (GPMR6176)
for long surfaces such as wing leading edges. The Easy-
Touch Adhesive-Backed Sandpaper comes in 2” x 12’
rolls of 80-grit (GPMR6180), 150-grit (GPMR6183) and
220-grit (GPMR6185) and an assortment of 5-1/2” long
strips (GPMR6189) for the short bar sander. The adhesive-
backed sandpaper is easy to apply and remove from your
sanding bar when it’s time for replacement.
Custom sanding blocks can be made from balsa or
hardwood blocks and dowels for sanding difficult-to-
reach spots.
On our workbench, we have three 11” Great Planes
Easy-Touch
™ Bar Sanders, equipped with #80, #150
and #220-grit sandpaper. This setup is all that is required
for almost any sanding task. We also keep some
#320-grit wet-or-dry sandpaper handy for finish sanding
before covering.
