Not too bad, as the overhang from the bogie pivot isn't that great. Also body mount to body mount can take reasonably sharp curves; it's body mount to bogie mount where the troubles start.As the Man said:
Keeping body-mount couplers together, on those, is no mean-feat!
Out of curiosity are those DZ wagons variants of those 2ft gauge examples imported from South Africa by the Welsh Highland railway over here?The DZ's are evolving nicely. Some chassis candy.
The 3ft6" DZ7 was a way bigger wagon of course. As a matter of interest, the NG versions were DZ2 and DZ10's To compare sizes I am including a couple of drawings so you can judge the sizes. First two being 2ft gauge and the last one 3ft6
Have a look at both of my Battery Railcar Bash threads where I made up the Sideframes from scratch. Much of it was metalwork and some turning, but Plastic Card and Plastic rod would have worked just as well.Compliments of the season to you all.
I am currently taking a break and contemplating new stuff hehehehe.
I did decide though, here around Christmas, that I need a track tester. You know one of those locos that makes things really difficult for you whenever it can.
I am a fan of the the old GE U18C 1 we had here. It was called the class32 and was to my eye a very good looking loco. And because it had the pony trucks either side of the CoCo...pivot points would move inwards enough to make a lot of swing at the bulkheads.
But....where do you start? I have never built something like a loco.
Got some drawings and decided to have a go. I have built buildings out of foamboard before. Main reason being that i have very little tools here. And the foam i can work with my hands. Little sanding block, Dremel and a carpet knife.....off you go.
I cut some shapes to get the GE rounded top. Decided to clad it. Long story.
Look, it is going to be my tester....but even so, I want it to at least look half decent. Cut a cab for it out of perspex. I have done a mockup chassis which i plan to do out of 6mm mild steel for a bit of weight.
Biggest job is going to be completely homemade sideframes. Currently its standing on USAT blocks and SD70 frames.
Will do those last. I am one third in with the body.
What about having the USAT block the other way around, then having a pivoting axle at both ends? Would that make the beast more flexible around the curves?Will have a look.
Here is my dilemma. If i make a solid sideframe, i would have to make the pony axle swivel from the middle of the of the two sideframes. Like in real life. But i checked, with a dummy axlebox on there, the swivel is severely compromised. It just takes a R5 turnout. And even over that the axlebox rides against the frame.
But if i attach a whole new section to the swivel end of the USAT motorblock, it tracks beautifully but that would mean a small gap in the sideframe and them moving seperately, like in the mock up pic above here.
