LGB Knuckle Couplings

grabcad

This is a set of working knuckle couplings for G scale railways. These fit "standard" LGB fittings.The "fixed" coupling is a single self sprung part. Each coupling comprises the body, a small retaining cliip and the knuckle its self. For free movement I use a 8mm round file after printing to clear the 8mm dia hole in the coupling and make sure it moves freely on the body housing. There is also a moving knuckle version that uses a bent wire interlock that enables it to unlock prototypically. I use this version in my servo operated couplings. The three "Body variants" work with different LGB bodies to avoid having to cut the coach/wagon /loco bodywork. I use the middle one for my 3D printed wagons.
