This week I have some good news for my OO Gauge Fixed Link Couplings.  All the designing is done and the sample packs are ready.  If this coupling project is new to you, you can read more about it in the previous post here.

All of the different types of OO Gauge Fixed Link Couplings can be seen in the table below.  The main couplings are numbers 1, 2, 7 & 8. These should work for the majority of models.  However as I described in part 2 of this project some manufacturers have set their NEM sockets at different heights so I have also supplied adaptors to cover all situations.

The first fifteen are the shortest and designed to give 18mm between each NEM socket.  Should your layout have tight curves or you have a model with the NEM socket set further back then all the couplings have been repeated for 19mm and again for 20mm.  The extra distance on tight curves will avoid buffer lock which can derail wagons.

Both the 5.5mm Step Up and the Loose 3 Link couplings were a special request from a fellow modeller so I have included them in the range.  Please note that the 5.5mm Step Up will require any existing molded hook to be removed from the wagon but it will put the coupling at a more prototypical height. Also the Loose 3 Link only has the center link loose, both outer links are fixed; this means there will be some slack in the coupling but it’s only good for pulling rather than shunting.

Given how many different types are on the table I’ve made five different sample packs available.
