    Hi

    By mastanec,

    .
    Hello and welcome to my blog.
    My name is Marian and I am from Czech Republic, country located in central Europe in the so called "Czech basin".
    We have been there for some time now, since times of great merchant Samo.
    Lets fast forward trhu the centuries, dukes, kings, monarchies and regimes and lets stop in 80'es - 90'es, era IV, era that I have deciced to model.
    And that is because of all the variety it offers, that is a lot of liveries, ones that were strictly adhered to as per official norms, colorfull ones thanks to losening of the political situation and the mix of CSD and CD. A bit faded look to everything.
     
    Here on my RM web blog I will present mostly models made by me, but also other things of railroad interest, mostly Czech, but I won't restrict just to that.
     
    Hope you will enjoy!
     
    Best regards
    Marian

    I have never built a scratch built model before but I have always fancied the idea and was impressed by works of Czech modeler Vladimir Klusacek aka. Tempotaxi.
    So I decied to give it a try as well. I should have had chosen an easier model for the very first time, but hey challenge accepted and by now it's almost complete and would be pitty to give up on this stage. It also took me a lot of time to get here, expectations were different. I will not go in depth here on how to scratchbuild... it's not that difficult, but requires a lot of patience, sharp scalpel and something to make right angles by.
     
    The prototype:

    2 truck 4 wheel hopper balaster car type Faccpp 411V.
    Manufactured since 1972 in Zielona Gora, Poland. It was made in multiple modifications, the 411V was Imported to Czechoslovakia for track maitenance, main use as track balaster, the height of hopper tip is adjustable and emptying of the cargo can be done whilst the car itself is in motion in speeds up to 5kmph, the material is spread by the tipper at the same time.
    It has spine like main frame to which the trough itself and control facilities are attached. The car is fitted with 2 diamond style 2Xta trucks.
     
    The model (still in progress):

     
    I have started by gathering documentation and pictures, there are very few pictures of this car from the CSD era, I had to ask veterans for some csd pic which has been sent to me. Also there are very few decent drawings so I had to improvise on some parts, eg. the hopper tipper is 2 mm shorter to allow for the trucks to turn in sharper curves than prototype. When I thougth that I have gathered enough resources I have started working on the main hopper trough, cut out of card styrene 0.3mm thick, glued this together and added tipper part to the bottom. Once I had this block I started attaching the detailing on both sides made from plastic half ring profiles and metal T and L profiles.

     
    At this stage it become apparent that I need to start building the spine frame and buffer beams in order to be able continuing building. The frame spine is from rectangle shaped brass profile and the buffer beams from evergreen styrene rectangular and C profile detailed with etched brass walk and buffer bases. I would have like for the complete frame and buffer beams to be completely metal as tehre is very little space underneath to conceal some solid weight, also the spine on this model is not exactly the same shape as on prototype because I did not have the proper drawing neither decent pic of the inside of the trough.

     

     
    At this stage I added the etched detail bits and also blasted it with few few thin coats of yellow in order to get the paint into difficult places before I complete the whole model.

     

     
    This is so far how it looks for now, with that I have now added the regulator and plough part.
    What still needs to be done:
    - buffers and air hoses
    - handrails on bufferbeam walks
    - handles for air control system of the hopper and tipper
    - finish yellow paintwork
    - paint both bufferbeams black
    - fit a little more etched detail (brake selectors etc.)
    - get someone to print me decals
    - weather and play!
     
    updates to follow hope you enjoyed it so far.
     
    During the building I have also side stepped to my other hobbies and little bit of learning with 3D SW and my first 3D printouts:
    Material 1, Prime Gray; iMaterialise
    results rather unsatisfactory, layers are very visible, a ? (T) profile has lost the I in it and left just the base _ this version of the cad model did not have stamped sides.
    Not worth the 20€.

     
    Test print 2, drawing version 2, SLA - Frosted Ultra Detail, Shapeways
    Well now we're talkin!
    I have read tons about 3d printing before I tried it and was aware of downsides FUD can have, its very fragile, in pic below you can see some corners already knocked off, next time delivery with support material. But this is value for money and material of choice for now (I mean near future):

     
    I would like to have a set of these at some stage, having actual physical model helped a lot with planning for 3d prototyping and future production of few more pieces at affordable price whilst not spending ages sculpting every little piece to same dimensions as the other one.
