Buffers and couplings

 

Both buffers and couplings on this kit will be familiar to anyone who has built an O gauge kit. You can see the buffer components above. The only glue required is to attach the ring to the face of the buffer body. 

I screwed the nut half-way along the thread as doing it all the way up seemed to leave too little buffer shank showing. Maybe I'm wrong there, but it's my model, and I like it this way. 

Couplings are again, the same as a 7mm kit. The hook slides through the buffer beam, a spring is put on the back, and retained with a split pin. The only difference is that the chain is chunkier, and needs lot more bending to open out the links for fitting!
