another Lulonga model

[Tomas Krejci]

Hi gents,
I would like  attach to my article> > Another Lulonga « on: February 16, 2013,where I describe the construction paddle wheels at this model  <   a series of images that I put here, describing how I built my Model Lulonga.

If you will have a questions about the construction, I will answer it


During the construction I used different materials. Hull is made ​​of plywood and balsa, plywood deck, superstructures made of hardened polystyrene(psh), front superstructure is  psh , but also covered with veneer boards.
Stacks are made of cardboard tubes, small cowl vents purchased, cast from resin. Large cowl vents are pressed from psh and paper laminated tube 10 mm dia.
The railing posts are made of brass split pins 1 mm dia x 42 mm long, shaped with   pliers on the simple template with nails , the railing is made of brass wire 1 mm dia.
he towing hook is made from an old compass, brass plate, fixed with screws through the al block to the base in the aft deck (below the  aft superstructure).
Companionways - psh. Punt -psh + wooden grate ,Oars and paddles.. wood sticks and skewers.
The sand for the rudder, compass and machine telegraphs  I   turned by hand chisel using the electric  drill .
Two independent quarter paddle wheels are  driven by two electric 12 Volt motors with a gearboxes , controlled by speed controllers. (yet in construction).The transfer at the paddle wheels  is made  by toothed belts. (round 80 - 150 rpm at p.wheels)
 Electric drive test   with a model in a bathtub met my expectations. It seems that the model could be quite fast on water....
I am considering about  steam sound module too.
Side hull height I increased by about a centimeter, it gave me a greater reserve of displacement. My  home-made paddle  wheels  are quite heavy and model, built as quarterwheeler has  a small reserve in the rear displacement, which I  will have to balance with  heavy loads or heavy Pb batteries in the front  part of the boat.
At present I have to build winches, anchors ,stick veneer panels on the front deck and stick companionway.. and more a lot of other little things that most time-delay construction ..
Sometimes  I quite envy the people that built ship models from kits ..
But srratchbuild has its secret charms and examine every modeller  ...

Very well done, Tomas,
Love all the detail you have incorporated
Where did you get the construction drawings please.
As had them ages ago, but with life's ups and downs, and a couple of changes in country since, no longer have them
excellent work

Hi Kiwi
The most complex - (not to say the most difficult) was to think of as simple technological process for every detail, which started dividing the individual components of which each larger units composed, by drawing these components, then the cutting, grinding, turning, folding, and set forth a procedure for bonding painting ...
This is what I had to basically receive for every detail. While they are in the modeling literature describes the procedures for the production of these parts, but You as a modeller have to a more-or less adapted according to your possibilities.
Usually I have each part drew in axonometric projection, so I made ​​a visual idea of ​​how each piece will look like, where it comes attached, so I chose accordingly forward or drewv quoted form of technical drawings and worked on by them. Thus I fell off the constant re-measuring proportions of every detail in the drawing.
