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
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
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 ,MARIUS
