 | | Bogie design (coupler) —Sonnich Jensen
|
| | | Hi all! I am working on a new train, and I am blocked with the bogie design. It is a standard small bogie 6x4, but I do not use a normal coupler, as I do not want the buffers, secondly, the coupler must a bit away from bogie it self, something like (...)

Also: 1) I cannot attach a beam to it and keep in in position. 2) using it as an extension is not an option as it is too wide (2 studs - well 1,5 from (...)

That sort of thing is often done by builders who are putting their trucks somewhat inboard of the car ends so that the magnet can swivel freely and can reach the car end to mate with the next car. Real cars body mount their couplers in (...) (21 years ago, 28-Nov-03, to lugnet.trains)

| | | | | | Even better: by using this part: Technic Rotor 2 Blade with 2 Studs [LDrawPart 2711:7] you can achieve the desired 2,5 stud offset, by putting two Plates 1 x 1 Round under the part (one in the hole at one of the ends and the other right next to it) (...)

I wondered about the strength at first but the fact that the stud on top of the "Technic Rotor 2 Blade with 2 Studs" meshes with the bottom of the bogie plate just adds (...)

| | | | | | | Instead of a bogie plate you can always use a Tile, Modified 2 x 2 with Pin [LDrawPart 2460:0] This gives you more flexibility with how you attache beams etc. you alos don't have to have the pivot poit in the centre of the bogie. Tim (21 years ago, 1-Dec-03, to lugnet.trains, FTX)

I actually use this in MTW-1003 because I want the wobble this gives you (it's a bit taller of a pin than a normal bogie plate's pin which fits into two plates worth of space, this is a full brick thick or 2.5 plates) but the flexibility (...)
