|HO scale narrow gauge 25 foot cars [message #52026] Sat, 28 July 2012 13:32 UTC
I'm planning on producing some of the rolling stock of the Ohio River & Western Railway, a 3 foot gauge railroad.They are suitable for both HOn30 and HOn3, there will be versions for both gauges.They are designed to sit on my trucks, available for both gauges.|
The first one available is a flatcar, with or without stakes.
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:

I have updated the design, as part of the queen-post was too thin and fell foul of the thin walls rule.At least one order was rejected because of this.|
The new version 'should' be ok.Apologies if you have been affected by this.There is a degree of uncertainty about detail parts and minimum wall thickness.

My first design is with integral roof and roofwalk.The floor is a separate part, attached to the body by 4 bits of sprue.Take care to not damage the stirrups when separating them.
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.
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.

I've now added a caboose at last.HOn3 and HOn30 versions, same body, different chassis.|
The body and chassis are linked together for printing by some small linking pieces.Cut through these to separate them, inside you will find the roofwalks.
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.

The new ( to me ) design rule about minimum wire size is affecting most of these models. It's going to take me some time to work through them and modify them. Until then there is no guarantee that any of them will print , even though they have done in the past. |
edit : I think I've done them all , so they should be ok now. I've taken a few models off sale as I don't think it's worth modifying them.

The build continues.|
Body painted, Lead weight and glazing added inside the body.
A roof for the body, made from some styrene sheet, in this case planked.
Trucks (from my range) added, airbrake fitted. The couplers are Microtrains 1015.
Roofwalk fitted to the now painted roof. Handrake wheel made from brass.
The open part of the car can be customised or used any way you like.
