WIP MOC: German Tri-axle Carriages
Posted 08 March 2012 - 11:32 PM
I have a couple of questions:
1. Does anyone know how to make rounder roofs? Something round like part 61487 (which seemingly exists only in white or green) would be perfect...
2. Is the coulour for the bottom of the body correct? I am tryin to represent the sloping effect at the bottom of the body as one can see on this link

With the inverted slopes you don't need that many as they are stiffening ribs that go from the underframe to the coach sides, if you have a good look at the photos you will notice that as well as the other fitting such as brake cylinders and battery boxes etc, black is the right colour to use for that.

Indeed, however While not being a purist, I find it difficult to procure stickers, let alone use them. Basically I can easily find printable decals, but I have yet to find prinable vinyl sheets.
I tried with black and I find it to "pure": gray looks a bit weathered. As soon as it is possible, I'll post a version in black next to a version in dark bluish gray.
Yes. I use an an articulation system. The centre wheel is sliding on the frame and using universal joints causing the outside wheels to turn. I made a mock-up to see whether it works.

Solutions which could work
Light Bluish Grey 45411: But ouch these are expensive parts
White 54095: But probably too wide
Light Bluish Grey 88930: mounted at right angles to each other with SNOT techniques
88930 counterpart 61068
58883 mounted upside down, with tiles to cap the bottom studs?
The wheel base mechanism would be a worthy thing to look at!

Very nice Umbauwagon, I've built a few of the longer version so I'm always interested to see someone else's. I like the idea of the slopes to represent the bracing, but I agree with Steinkopf, the actual wagon frame is vertical set back from the body edge, with only thin diagonal bracing. Perhaps use only a few slopes to represent them, and I'd choose the black same as the rest of the floor.
I'd also love to see the design of the wheel articulation.

That's what my thoughts were originally but given the coaches are 8 wide I think it will make the centre section of the roof too flat as there is a fairly pronounced curve in the real life version, if the coaches were to be made 6 or 7 wide the 6005 arches would be perfect.

As for the roof, I think I'll stay with the current one: although it has more of a parabolic rather than half elliptic section, it is easier to build. I'll post a picture of the new design for the lower body as soon as it is ready.

Two videos with a lock on s-curves:
By the way, don't the curves when one goes through a point have the same curvature as normal curves?

Hi Frank, check out the Flickr link in my signature to see what the 8 wide roof looks like with the curves that peterab suggested. I made a similar tri-axle wagon for my BR50 which is an interpretation of the locomotive and wagon that are at the train museum in Blumberg Germany. I like the solution you found for the third axle. As my solutions didn't work properly I actually had it running on 4 sets of wheels on the track (you will see that in the video here), and switched it back to 3 axles when on display.
I am looking forward to seeing how yours turns out!

The bricklink part orders are gone... I'll show the photographic/video results as soon as the building is over... I am adding a boxcar which is of the approximate Ghs 30 "Oppeln" type (see that link -- the photo is very big, so no embedding)
I am already full into my next project: a (062)+(260) (i.e. (C1)+(1C)) articulated tender locomotive of the "du Bousquet" type (see the wiki page or that page). In 8 stud wide it will have a length of about 42 studs. Here is postcard depiciting the loc:
The coulour scheme is one of: chocolate brown ("Nord" scheme -- the one on the postard was in that scheme) ; a rather expensive coulour, jet black ("Est" or "Ceinture" scheme) or black with green tanks (SNCF scheme -- after 1938). I think I'll go for all black...

I use the gray ones for more moder trains...
