I've bought an old Airfix 00 brake van kit off Ebay which I'm in the process of building and detailing - replacing handrails, wheels etc. I've bought some Smiths 3-link couplings from Mainly Trains and, having never 'installed' them before, am rather struggling to know how to go about it.
I guess I need to make a slot in the buffer beam to take the coupling but I'm not sure what tool to use for this job. Also the underframe has a rather chunky moulded Kadee coupling mount right behind each buffer beam which could make things difficult as well as meaning there isn't room for the back of the coupling hook.
I'm also not sure what the springs are for!
Any help would be much appreciated.
