NSR 4 wheel coach.

Thanks. was more confirmation as suspected that's what it may be (from later brake systems) but wasn't sure for this period. I have something similar drawn for the MTV wagon... this may actually solve that last issue ! 2 for 1 ! boom ! It's a case of sitting and drawing it now. Back at work now.

Ah, not my drawings...Simply repairing damaged STL files. and I think I'm going to replace this with a better detailed one I've done in the next few days.

 

Following @Mossy ’s drawing of the brake rigging I spent some time yesterday evening setting it all up.. and then today I still find an error which amassed to extending a link by a whole 2mm!! Just to stop it fowling the axle!

for clarity, I’ve painted the main brake pipe red (it can be black) and shows all the underside with the wheels removed.


A close up showing it in a little more detail. At the moment I have the pins in, but once I’m happy re placement etc, I’ll knock them out and make holes for real pins to sit in when printed, just to make assembly a little easier and more “Airfix” that solid build..

I also chose to swap the vacuum cylinder for one of drawn earlier for another model.. now I’m assuming these are all the same size? If not I need to shrink it as I have two issues here.. one being that it sits inside the timber frame of the chassis, and also sits in a slightly different place to the original so the block under it sticks out.. that may mean re editing the chassis again, but not an issue. What I may do is leave a small cross bar from inside to outside and cut a slot in the vacuum cylinder to make the locating easier.
Thoughts?

 

I found out that the cylinder size should be an 18” one for the coach and I therefor resized it.
I have also edited the chassis and removed the block the old vac cylinder sat upon.
The air tank has also been redrawn.

Next up was an experiment with the NSR Crest. (I’ve also found where the coach numbers should be!) had to cheat a little as Fusion will not let you apply an image to an STL file and the work around was to create a panel with a tumblehome to as close as I could to the model profile..

Reversed it 180 and align to the other side.
It’s only been added to one model at the moment but it adds to the look.


I’m now at a point where it’s time to start assembling the parts needed for the printing side to make it (new resin and other bits expected for the weekend) and also send them back to Mark who supplied them.
I’ll report back soon.

 

Thought best to crop it so you can actually see what I’ve done.. doesn’t like transparent so had to paint the crest the same colour as the body. Still shows as a different colour slightly due to gloss finishes etc..

 

Oh yes, many thanks

 

@Mossy & @paul_l

hopefully when the new bits arrive (resin and filter papers) and I’ve fitted a new fep as I’ve found dings in it, I’m going to start printing Friday or Saturday night whilst the wife is at work. (I can sleep though it whiring away in the room below)

what I could do with is some suggestions for laying the parts out. Ie angles. Coach body, chassis and the chassis beams, roof. (see the earlier post re the differing parts.)

Not sure what to do re printing the brake rigging. So again any suggestions.

I may omit the buffers.. but not sure what I’d use. (Bear in mind O gauge is not my first modelling scale really and less so kit vehicles.) but we can cross that bridge when I’ve printed it.

door handles and grab rails will also be separate

Andy

 

Roof and floor/chassis are separate to the body, 3 separate files. But the seating is intact in the coach.

there are second chassis rails with the W irons on..

 

The floor or chassis looks like this, but the square has been removed centre bottom (that’s where the vac cylinder now sits.. acceptable in OO but not O in my opinion)

so which side facing in to the supports and which out? The back side is flat and is the coach floor.
I have a horrible feeling that if I do the beams facing down, I will have to support all that text! Great for shapeways but not mono x

 

in the coach body to keep it square. That’s how it was first drawn. I’ve never took them out only the floor which was moved to the chassis

 

Copy sent. Good luck!

 

I dont follow... add 1mm holes to where ?

 

The printing has finally begun.


first off were the chassis rails and hornblocks
Little bit of bow in them
But that may pull out with warm water and then glue. The air tank, and just going out of shot some grab handles

the walk boards over the lower half of chassis


the body. Looks ok on first inspection, but sadly, it’s not. Unknown reason but the side edges have not printed well and distorted. Both sides

you can see where the edge should be by where the supports start. It’s even got that trim in place on the other side … grounded coach body rot!!



What I don’t get, and the other printers here may be able to fathom, the skate has all
Bubbled here - as if the surface blistered?
Start of a fresh new bottle.


Anyway, cleaned up, printing the chassis and roof now. Then hopefully the final parts during the week. We will revisit the body later on.
