LOS ANGELES class Sub on Scale 1/81 (I thnik?)

[profesorul]

And the last step :
- not having such thick material for WTC supports - and two component resin is very expensive here , I chose to do each support from light pvc , four layers of 2 mm glued , pressed and procesed on lathe - as seen in pictures .... a job that is extremely messy ,

PART: III ,

part II :

then I moved to the next stage of the work consisted of making a bronze bushings have inside a 6mm hole for propeller shaft and a small flange at one end.
Flange and also will be a stop on it will slip when the propeller rotates.
Bush I did - a smaller more remain outside as much as in material thickness will give aft cone when the hole for attachment.
I found a shaft 6mm long enough, worked extremely fine (it was to a printer) at one end which I did a 5mm thread for the adoptive propeller and screwing nut

HELLO There ,

I progressed a little work on the submarine. ...
Not having a laser level or other modern means of marking curved surfaces , I have found a way to draw a straight line inside the lower hull .
I did like the following:
On the exterior of the lower hull I had the axis allready trased – axis used to draw the flooding holes ...... I made a few very small holes along this axis , I’ve passed a more resistant rope inside the submarine , I caught as stretched out as I could at the ends , and on the other holes I made a connection to the outside as seen in pictures .
In the end I’ve put a few drops of glue on each link

OK That's it !.
I'm don with the flooding holes .
I don't want to hear NO more about Flooding Holes!!! .

these is the FINAL shape :

Looks good, as long as the hole is 1/8" (3mm) or bigger then it will be functional as well.

As Mr M says " keep it up ".

Marius,

Easiest way to do it is if you have a rivet gun. Drill a hole into a scrap piece of metal the size of the rivet, then fit and pop the rivet then slowly and steadily with a drill bit slightly bigger than the rivets hole drill the head off. It will probably get stuck on the bit but just reverse the drill whilst holding it with pliers.

Peter

HI PETER ,

What do You say about that ? .
- I enlarge hole in the hull approximately 0,1mm bigger than the rivet ring ,
- I enlarge also the hole in the rivet ring nd than I cut it the ring ,
The result is , what You see in the pictures below :






looks more OK than the rivet next ?.
The last picture shown the rivet ring with flat surface up side down but I don't like it . I'm gonna use the rivet ring with curved surface up .

Thanks PETER ,

All I can do is to tray !.

Comparing to 1/700 scale my job is "a piece of cake" .

MARIUS

[Peter W]

Aha , I see what You mean . At the end of these operation it's gonna be a small Aluminum Ring . But is gonna be Very Difficult to glue such small surface 1-1,5mm wide !.

MARIUS

CA applied with a toothpick job done, adding a slight rebate will help contain the glue, look on any static modelling site at the 1/700 scale photoetched parts and gluing those rivets will look simple.

O.k., do you have pop-ups blocked on your browser? The screen that comes up when you click on the photo could be considered a pop-up. Usually under preferences, but if you tell me the browser, I might be able to guide you.

The problem is like these :
- when I am on Forum , I make the first click looks like these :


After the second click on the same picture looks like these :


After I download on comp and I tray to open looks like these:


- after I download those pictures , my goal was to print them , to have them in front of my eyes when I did the piece , that's way I need them large .

THANK YOU for Your efforts to help me ,

PETER ,

I want to follow your advice but do not have the drill column and / or milling .....
I have hand drilling machine with simple drill bits and they make the bottom of the hole sharp .....
for the rivets I need to do a flat base hole ....

I hope You'll understand what I mean to say .
