It's time now to present this new project!
I have choosen to reproduce the sleeper deluxe you have in your auto train, the one with only bedrooms on the upper level and roomettes + family and handicap bedrooms on the lower level:
The shell is quite the same as the coach car; there is just one more window on each side for the handicap bedroom.
So many parts are similar and it avoids me not to re-draw the plans!
But there is one important and different thing: the way to build!
The coach car is for me a prototype and it means that for this new one, I have to remove all the defaults and mistakes I have made! most of them have been corrected by modifying 2 and 3D drawings bt also by changing the way to build this car.
The coach car had 2 main parts:
1 - the chassis: one piece with the lower and upper floor, the end faces, the partitions on both levels,
2 - the shell: the two sides and the roof
This second part fitted by sliding inside the end pieces and stopped by 8 locking tabs (4 by side) fixed on the sides of the upper level floor.
The assembly of the sleeper will be different:
1 - the chassis is now cut in the middle and the ends are fitted with bolts and nuts (in orange on the drawing) to give an access to the batteries installed on the low floor ends. You can notice that I have kept the locking tabs on the upper floor.
2 - the interior design is one and only piece and it will fit into the chassis (without gluing it)
3 - the internal faces, strips for rigidity and external faces will be glued together
and after fixed in place thanks to the locking tabs I spoke about earlier.
4 - the roof will be inserted on the sides before fixing the ends which have also locking tabs that you can see on the top of the left end (little cilynder in purple on each side); so the roof will be fitted in place.
Obviously, before gluing the external face on the rigidity strips, I will install the entrance and equipment cabinets doors!
I think this new way of building will bring me more accuracy and will make this car better than the first one.
I have begun to prepare some pieces but I will show you in another post; now it's time to go to bed!!!
See you soon
