Lil big hualer saddle tank loco bash.

Can the pony truck move sideways at the pivot or does it only swivel on the center fixing?
I assume the main loco wheels do not pivot on the chassis?
 
Thanks dunnyrail I will recheck that sounds like a real possibility. I hope I can figure it out. I really want to run this locomotive..
 
I assume you mean it twists but the pivot point is fixed. In that case, yes, thats your problem.
Either, the pivot point needs to be able to move side to side or the drive wheel unit needs to pivot.
 
Just found a picture of an alternative. You will see how they have moved the pivot point forward so that the truck more closely follows the curve behind the drive wheels - which are fixed to the chassis.
Also, it looks as if the truck can also pivot on the swinging bar.

Perhaps a bottom view like that of your Loco would help us to id the problem. If you have a piece you could even set the Bogies to their maximum throw and Test touch a small curve to the wheels to see if they fit. That should highlight the problem, solutions in part as above but with perhaps as ai said a but of bidywork removal and skightly thiner bogies to allow the wheels to move around a little.

I had a problem with a Buddy L loco and its' single axle pony. I was going to move the pivot point but, in the end, I added weight to stop it lifting out or climbing the rails.

As was....,

....and as it is now (which solved the problem)....

I'm not saying this will solve your problem, but it got mine to go round R1's and the reverse curves of same radii.
 
Wow thanks guys. Great information. I need to really learn more about the locomotives . Bogeys and ponys trucks and r1 lol. Track radius confusion me. I need to learn the terms and and parts of a locomotive. Anyways I think I get what you guys are saying. So I am trying something similar to the picture. It seems that the back set of wheels will be more like pulling a trailer. It it will be able to move side to side and swivel too. Here is what I got so far. And thanks so much for helping me out guysIMG_20180124_212109305.jpg IMG_20180124_212113773.jpg IMG_20180124_221549783.jpg IMG_20180124_213912308.jpg

the front wheels will be tackled after the back wheels. Sorry I'm not sure if the pony truck is the front one or the back. And is the the boogie truck the back lol. Thanks the pictures will help tremendously.
 
As I understand it....
A 'Pony truck' is a single axle, articulated to guide the loco, and distribute weight(?) - Also believe it can be front, or rear.
A bogie truck is where you have two axles (hence bogie). It may pivot on its' centre, when it is probably just a bogie, or on an arm, when it becomes a truck.

But someone who knows these things will be along to correct me in a minute! ;):nod:

You're obviously doing something right, it looks a brilliant model

That's also my understanding. However American terminology may differ as, for example, in switch / point / turnout.

Well thanks to all the help I got from you guys we are making progress . I have more cutting to do but it stays on the track at least now. Still needs tweaking.

I could be wrong but that looked like an LGB Radius 1 Point to me. I think earlier on you possibly quoted Diameter where we all tend to talk Radius on Curves that being of course Half of the Diameter.

For some reason I can't seem to wrap my head around the system of how they are numbered.
