Here are the two versions with stakes,fitted with the appropriate trucks and couplers.


To weight the model I glued some strips of lead between the sills.I used EZ line to make the truss rods.


This is the HOn30 version, painted and fitted with micro-trains 1015 couplers.


There are two small supports for the handbrake wheel at one end.They need to be drilled out to accommodate whatever you use, I used some 0.4mm dia. brass rod.The finished model:

The floor has 4 notches in it near the ends for the truss rods.I used a loop made from EZ Line, about 5 inches long.
The handbrake assembly passes through the platform and lower support at one end (arrowed).
Weight can be added onto the top of the floor before final assembly.



Assembled:


I was not entirely happy with the test prints.The layering (stepping) was quite evident on the roof.This effect will of course vary with print orientation.
By painting and sanding I was able to achieve a smooth finish.To avoid this I've designed a version without a roof.Plastic card (styrene sheet) is used instead for the roof.You will need a piece 27x89 mm, scored down the middle.This also works out cheaper.The floor is integral with the body in this version, with holes for the truss rods.The roofwalk is attached to the body by some bits of sprue.
I have not test printed this design yet, but in theory it should work ok.]]> pinddle 2012-09-24T22:44:53-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=58843&th=10371#msg_58843


The test print suffered broken stirrups, which I replaced with metal rod.To try to prevent this happening again I have added some support material, which will need to be removed during assembly.

These pictures of the raw prints show how the roofwalk comes attached to the body.This must be removed before assembly.





Assembly method is the same as the other boxcars, except you will need some glazing material for the windows.

There are no queenposts, but there are guides and holes for the truss-rods.



I've not got very far with this yet, the ladder is just a suggestion for the end.It needs lots of handrails and a handbrake wheel.
Note, on this prototype model the chassis was slightly too short, hence the cut-outs in the body sides.This has been corrected now.

See the next post for more useful info, the chassis is the same.]]> pinddle 2013-02-18T22:54:13-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=64443&th=10371#msg_64443 The model is printed with the body and chassis joined by some fine links.


Cut and remove these links and clean up the remaining parts.


There are 4 small holes in the floor to help with the truss-rods.
Here I have used E Z line, the ends are glued to the floor.



There are mounting points at each end for a brake wheel.


The body clips onto the chassis.]]> pinddle 2013-03-19T19:09:43-00:00
