HULL
ASSEMBLY - Hull Openings (Pt. II)
|
|
1.
With all the pilot holes drilled out it is now time
to change tools. For the next phase you will need
a Dremel moto-tool and several needle files.
Small needle files can be bought in sets with
varying shapes.

2.
The Dremel tool should be used first to grind out the
flood holes. A steel grinding bit is preferred. Shown
are the two bits. The larger cylindrical grinding bit
in the tool was used for the majority of the holes.
The smaller round bit to right was used on the smaller
floods (the object to the right of the second bit is
the mandrel needed for the smaller bit).

3.
Moving outside, insert the Dremel in each pilot hole
and grind out the hull material. You want to get close
to the scribed lines but not actually to it. Use two
hands as the epoxy hull is tough and the tool can wander
if your grip isn't firm. Switch to the smaller bit and
do the same thing in the smaller flood holes. Be sure
to clean the dust off your clothes before going back
inside.

4.
With the grinding completed, pick up your needle file
set and file out each opening to the scribed outline.
Flat and square files work best and new, clean files make
the job go quicker. A thicker square file is good for
bringing the hole out to the scribed line. Use wider flat
files to make the sides smooth and straight. Then, go
back with the square file and true up the corners. |

5.
One down, forty-two more to go! The upper right hand
flood hole is what you should work for. The edges are
straight, the corners true and the scribed line is no
longer visible. With sharp files and some practice the
average time per hole should be about five to ten minutes.
But don't rush. The effort and care you put into the
process will yield a better looking model.
Once
your floods are filed out and looking good, there is
one more step to the hull assembly section...

IMPORTANT
SAFETY TIPS
Always
wear safety glasses or goggles and a dust mask when
grinding with a moto-tool.
Always
work outside when grinding to keep the dust out of the
house.
