No go to the other end of
the control arm and bevel
that polygon three times.
a)
Shift 20 mm - Inset -25 mm
b)
Shift 100 mm - Inset 0
c)
Shift 20 mm - Inset 20 mm
19.
Go to the front of the control
arm and copy and paste the
polygons as shown, into an
empty layer. You'll use that
as a Boolean object. The composite
image shows the polygons involved
and the result after the Boolena
subtraction. The Rudder top
now has a proper slot in it.
20.
Neat little rudder, is it?
Now all you have left to do
is to "pin the tail on the
donkey". That is get the rudder
handle combination mounted
on the pivot. After all of
this work, save
file as ship_tute17.lwo
21.
Guess what will become an
oar? How about the rudder
control arm? Works for me.
Select it, make a copy of
it and paste it into an empty
layer. Select the point of
the knob at the end and with
<t> move them toward
the right, as show. The grid
is at 500 mm.
22.
Shaping the blade of the oar.
Take the point on the leading
edge of the arm and slide
them as shown. Follow suit
with the rest of them until
they are in place. The second
screen-grab is on a 100 mm
grid. You can easily see where
this is all going to end up.
A few cuts (blue line for
the initial one) will soften
the curve.
23.
All the cuts are in place and you can
shape the oar a little more. Blue arrows
indicate the cuts.
24. Grab the two rows of points
in the middle and use <h>
to stretch them vertically...and
the right image shows you
what you want to achieve.
25.
Now sqeeze the blade a little,
use <h>, and you will
be left with a very passable
oar.
26.
On to the Rowing benches/
sea-chests. With storage space
at a minimum on those vessels,
they used sea-chests as rowing
benches. Very practical. They
were found with curved and
flat tops. All heavily banded
with iron straps. Make a disc
and delete the lower half
of the points. Follow with
a box and you've got the sea-chest
nearly finished. They mounted
them on legs, I guess to keep
the contents dry. Two more
little boxes (one copied and
slid) take care of that.
27.Now
for the iron banding. Copy
the sea chest to an empty
layer. Take the knife and
cut a slice out of the middle
somewhere. Hit <H> (MODIFY/Size)
and enlarge the slice slightly.
It's your iron band. Delete
the rest of the chest. Copy
a few and spread them across
the chest. Then select them,
name them straps, and copy
them to the chest. Use the
same color you used for the
rudder pivot and hub, to color
the bands. I made them just
a little more shiny.
29.
And voila, one burly seachest.
Now you realize, that at some
point you will have to make
32 chest and at least 30 oars
and distribute them evenly
around the ship. I'll give
you some pointers. Of course,
setting up one quarter of
the ship and mirroring the
rest will pretty much take
care of it, with some adjustments.
On the 200 mm grid, stretch
<h> the seachest to
these dimensions. When you
move the cests around, make
sure none poke through the
hull.
30.
What remains is the sail.
The sail will be fastened
to the yard with hoops of
rope. So, go forth and make
some hoops. This is what we
need. Open an empty layer
with the yard in the background
and create these points. Connect
them with a Closed Curve.
31.
Go to an empty layer with
the curve in the background
and create a small disk in
the Front/Rear view.
32.
Swap <'> layers and
go to MULTIPLY/Rail Extrude,
set it to Uniform Knots =
20, and hit "OK". Name the
result "Hoop".
33.
Go forth and select, copy,
and slide, until you have
six of them, as shown on the
left. Then mirror the bunch
in the Z axis. Save file as ship_tute18.lwo
