Periscope, antennas, radar and smoke stack:
Take a close look at the sail top view below. Notice
the six small door like spots? These are the doors for the periscopes,
antennas and diesel exhaust stack. As these can be withdrawn completely,
you can decide your selves how many of these you want out in the open,
and to what degree you will use them
as suggested in the “Add-on’s” chapter. (Able to
extend / withdraw by remote.)
The other image from the Internet show how these details can be fitted,
and what they might look like. Form the pieces in metal if possible, and
consider making them able to unscrew so they can be removed prior to
transporting the model, if you will not be able
to withdraw them into the hull.
Mine will be manually extendable, with a mechanism involving a
magnetic locking up and down. The fore-most scope will stick up enough,
so that I can pull the mechanism by it.
||By looking at
various pictures, I had an idea on how my scopes etc. should look.
The first thing that I noticed, was that their base was oval, not
round... How to do that?
Well, thanks here goes to MacDonald's! One
day at the local Mac D, I was sitting with a straw that was oval by
mistake. Home I went, with two unused round straws, pressed them
oval as shown in the picture, and poured pure resin into them, and
allowed them to cure. (Remember to close one end..) The size is perfect for 1:81 scale!
The two metal "spacers" used here were chosen from their diameter,
so they'd equal the measurement of the scope's thinnest measurement.
||After the resin had
cured, the straws was pulled of.
Resin does not stick to Mac D.
straws. A small hole was drilled a bit into the scope, and a carbon
rod was inserted. (App. ½ inch.) The amber light was fitted in one
of the short ones.
the scopes was painted as I had seen them on various pictures.
First they got a light grey base, and black
tops. The short ones are fully black, as they will be fitted in the
holes in the sail, without being able to extend. They match the top
of the long ones one and one, so when all's withdrawn, it will be
impossible to see which are extendable, and which are not.
||The next day they got their spots, painted them all in one stretch, so they'd be
as much alike as possible.
The paint scheme varies a bit from SSBN to SSBN, but I saw that the majority had 'navy leopard' style painting.
The spots are painted in dark
grey, not black. This gives the scopes more visual depth.
Also in this picture: The navigational lights
that goes in the sail as well.
two scopes was molded into an anchor block made of pieces of pcb,
A small alu tube (inner Ø=2mm / 0.07") was included to serve as a
guide, sliding over the black carbon fiber rod. (Giving a secure and
vertical path of movement.)
Magnets was included in the resin as shown with the blue pointers in
the picture. A forth magnet went in to the lower side of the sail
top. These magnets hold the scopes in either extended or withdrawn
Inside of missile deck, below sail.
The two fixtures serve as a resting point for the scope bridge,
which again holds the lower end of the carbon rod.
A tiny 2mm / 0.07" hole was drilled a bit into the sail top, thus
supporting the other end of the carbon rod.
fitted scope bridge, made of pcb. Notice the scope block visible in
the bottom of the hole.
The scopes are extended, and held in place by the magnet in the
scope anchor block, and the magnet fitted on the lower side of the
Scopes on their way to the withdrawn position. Shortly the magnet
in the lower part of the anchor block, and the magnet in the scope
bridge, will catch, locking the scopes in position.
Scopes fully withdrawn, and locked.
tiny black carbon rod (Scope top) that stick up, is actually a
handle, and by pulling it, the scopes extend.
But which two? Can you tell?
Please notice, that the fifth mast with the amber flashing light is
not fitted in this picture.
This fifth mast will be permanently fitted, sticking out a bit, so
the amber light can be seen at all times when turned on.
Also please notice, that the two scope tops of those that does not
extend, are made just like the long ones, thus making it impossible
to tell fake and real apart. The reason for not making all scopes
extendable, is that it would crowd the sail.
The two fake ones are glued in one side only, allowing water to
drain from the holes.
Scopes fully extended, and locked by magnets. A small push by hand
will withdraw the scopes.
This entire thing with the detachable scope-bridge serves the
purpose, that the whole thing can be removed, and replaced, should a
scope ever get damaged. (Or automated later??)
